All the merit for Lode Vandevenne. This raycaster may be reduce in size dramatically creating textures on the fly, just time for that ;)

Brick walls and grass floor generated on the fly. This last one can be improved, but the bricks walls are neat, I think. I can make more type of textures on the fly. In any case the file size uncompressed is 62kb uncompressed and before now was 380 Kb, with the same tune in the background. Quite size save. :bgrin:
Edited:
1. Added another texture that pretended to be a heat metal grid for the walls
2. Substituted the ceiling by a cloudy sky.
3. I could make more textures on the fly but don't know if it worths
--> Brick walls and grass floor generated on the fly
reminds me of Wolfenstein Castle. :lol:
looks great,textures on the fly is what makes it look great independent of distance with no need for a mip/map solution?or you use mipmap too?
usual problem with using only one wall bitmap is it doesnt look good at distance
No mipmap involved here, it's just that the textures are bigger than before
Great Stuff Caballero! is there a tuto coming?
Thank you, Alex
I think I could make a new chapter if at least you are interested on it. Though I need time for that, family, job, my own time, time for my own learning. You know, few free time.
My flag, a sine wave example

The flag effect is a nice exercise, easier to say than to do

It depends on the algorithm you're using, it can be done with 64 to 128 pre calculated values. ( depending on the animation speed )
What is your algorithm?
You have to define the points in the flag that have to be waved, and the tone of color according to it.
Which algorithm do you use?
1 - Create a coordinate grid for the flag including the colors
2 - Create a sine table ( X,Y ) for a full rotation with the radius and steps you need for one coordinate. ( power of 2 size )
3 - Now step with linear interpolation thru the sine table and increase the X,Y coordinate added with the new X,Y sine position.
X starts at 0 degrees.
Y starts at 90 degrees.
Each next horizontal coordinate is one step further in the sine table.
( You can also use the sine values to add some shadow to the colors )
To speed things up, you only have to calculate the left horizontal half of the flag because, it is one full X,Y rotation.
You can copy the coords and colors to the right half of the flag by only updating the X coords.
I'd like to see your example, let's see that red/white/blue waving flag :t
:t
Next week, can't find the sources.
I'll have to make a new one.
Ok, I'll be here :t
I'm trying to do the filling of regions for the quadrilaterals
Flat color for the flag. Still appears some nasty black points that have to removed... someday
No acelerated graphic card involved here and no predefined function, just the all by hand :biggrin:
They are not nasty, if they were more shiny, they will look as the reflexion from the sun light or something like that. :icon14:
Btw, this flag seems to say GOOOOAAAALLLL!!!!!! :icon_mrgreen:
really nice flag :t
I had same problem with black pixel when floormapping,either you start filling the first pixel or last filling end pixel doesnt work properly
:t
And some shadow, from the sine table?
Yes, a palette according to the sine wave

Better start cracking, you don't have much time left. :P
Hello.
This version is similar to the previous one, except that this one makes an animated gif file in the same folder than the executable with the waving flag. All made with the all-made-by-hand GDI. The interesting of this one is just this: all made by hand.
When I have time I'd like to do:
- Allow to design your own flag, that also could be dumped to an animated gif.
- Improved the painting algorithm to remove the black points
screenshot from ubuntu, exe ran in wine. :biggrin:
Aha, it looks fine :biggrin:
I hope to have in a short time a version to be able to design your own flag on the fly.
So finally you opted for Ubuntu. I installed my son in his laptop bodhi linux (https://www.bodhilinux.com/), quite light and pretty.

Hi Alfonso,
Nice stuff.
We discussed the flag routine, I'm still working on it. ( sorry for the delay )
It will all be done in 2D mode, so no fancy 3D stuff.
Hope to show it soon to you, first finishing my other project ( fast SIMD Matrix transposition building blocks )
Here's a pre release, I still have to finish the shadow and the XY movement code for the final result.
Hi Marinus
You're welcome. It would be nice to see it when you have finished it :t, take your time. I'm working now on making a window to design any flag on the fly and save if in a gif. After that I'd like to improve the routines.
wow Caballero,I wonder how did you do it,so it behaved cool strangely on my xp computer?I clicked on 'x' on window and window+black background disappeared and a rotating 3dsphere was still on my desktop,but everything around it was transparent,I was able to switch to other windows also and when I wanted to close it I clicked on the sphere and esc
very nice flag Siekmanski
SIMD matrix blocks?,sounds very interesting
now when being busy with working with graphics,I see a need of support group hierarchy when you need to use complex 3d objects in a game or demo
does that need some recursion algo to go from highest group 3dtransforms to go down to tiny details,to lots of very tiny parts of objects when it explodes
Can't wait to see your new flag design. :t
My routine is divided in 2 ways to draw the flags.
1. simple 3 color flags need only 3 pixels in memory.
2. advanced flags will be loaded as color/size reduced png or jpg images and are as small as possible without losing too much detail.
@ daydreamer
Yeah, the pieces flying around due to the explosion need their own world transform matrix per object.
The SIMD matrices are in different small row and column sizes so we can build a very large Matrix Transpose algorithm for all sizes.
I'll post an example routine to time the matrices soon to see how fast the small blocks will be on different computers.
It reminds me of building with LEGO blocks when I was a little kid. :biggrin:

Hello, this is a prerelease :t
The interface looks okay, but I think it would be easier to use if the user didn't have to click on each 'pixel'. While the left mouse button is down, couldn't we just continue to the next 'pixel' (using the same color) without having to click each individual 'pixel'?
Just a thought. Also it would be very hard to make a remblence to the US flag. See my new avatar, I put it up just for this post. 8)
I don't expect you to rewrite your code to my specifications, but just to let you know that one size may not fit all. But I do like the idea of an automated designer. :t
Yes, it wouldn't be easy to make the us flag, it would be needed more points. With this only an approximation. I would like to make a more advanced version later. This version is more simplistic.
Edited: Now you can draw holding down the left button of your mouse

Yes, it is not finished. When it is, you will see the waving flag of Spain and pressing the "1" key, you will access to the flag design window, if you accept, the waving flag will be what you have designed. If you checked the "save to gif", it will generate your waving flag in an animated gif with the name that you write in the edit box.

Nope. Built from the ground up, pixel by pixel. :biggrin: Using MS Paint fron Windows xp. :bgrin:
I now have I think the smallest possible flag that still bears resemblence to the original. The larger one was to distracting.
The original idea came to me when I was on another forum years ago and needed an avatar. Many of the members there
had a flag to represent where they are located, or were born. So that is when I made my first pixel flag.
When I saw yor flag designer GUI, it remnded me of the old days.

looking forward to it,I already tried make several flags
it would actually be nice to have background from your masm32 Clock as flag,would be an excellent avatar here

Well, this is a beta version, there are still some mistakes, but it admits your flag design and saves it as a waving flag in an animated gif.

- Always with the name of "spain.gif"
- The background is always black

So forgive any misunderstandings. :biggrin:
brain freeze
Not to be overly critical, but the flag waves in the wrong direction. The pole would be on the left and the wave should travel to the right. (at least on the American flag - other countries flags may not have a left or right side, but for the US flag - the star field is always on the side of the pole or other mounting - and is displayed usually with the star field on the left hand side)
You demand a lot, for what you pay :greensml:

nice work caballero :t
This bulls**t is taking me talking to myself for a while, you see, it's a work in progress. No acelerated graphic card used, no opengl or directx, only gdi. If anyone want to test it and tell me, here it goes:
- You must unzip the three files in the same folder to execute it.
- Turn on the speakers and loud them, it worths.
- Some nice toys as lambert and environment mapping, etc.
- The best is that you can move freely the camera:
* E: move forward +Z
* D: move backward -Z
* A: move up +Y
* Z: move down -Y
* Q: move to the left -X
* W: move to the right +X
* X: rotate to the left in the XZ plane
* C: rotate to the right in the XZ plane
* R: rotate up in the plane YZ
* F: rotate down in the plane YZ
* T: rotate to the left in the plane XY
* Y: rotate to the right in the plane XY
Known bugs and todo list:
- I have to incorporate also this two files to the resource.
+ I have to incorporate the mouse and the cursor keys to move the camera (already done).
+ It increases the memory usage continuously, I have to fix it. Take care of it, nothing serious though, but don't take the program running for hours Already fixed :biggrin:.
Edited: In this version I have incorporated the mouse and the cursor keys. Same as the previous one, but with the mouse you can rotate left/right/up/down. With the left/right mouse button it will rotate left/right. Use the cursor buttons to move left/right/up/down. I have fixed the memory increasing too.
Very interesting :t
Nice, I like the colors of the Spherical Environment Mapping object very much. 8)

Here is the version with the built-in mouse. Same as the previous one, but with the mouse you can rotate left/right/up/down. With the left/right mouse button it will rotate left/right. Use the cursor buttons to move left/right/up/down.
I have fixed the continuously memory increasing.
It will move according to how fast the mouse moves, so don't be rough. :biggrin:
I left it in the first post so as not to occupy unnecessary space.
Another proof with stars
Nice :t
Cool effect.
Which random routine did you use?
Hi,
It ran on Windows 2000. It ran faster on Windows XP. The
near-field stars had some jitter or rough movement. Overall
very nice though.
It did not run on Windows 98, it raised an exception.
Regards,
Steve N.
Hello
@Marinus. The random function is the c standard, but only used at the definition of the cube of stars. The motion is just rotating and translating the objects.
@Steve. Thank you for testing. I think that the jitter is due to the speed to the rotation of the stars, more evident as closer to the camera, unless I am using at some point integers instead of floats. I wonder if the error raised in the W98 is due to the mod player. I attach a version without this player, if you could test it again in W98 and tell me how it worked. Thank you.
Hi,
Yes, that one runs on Win98. Runs slower, obviously, but it
seemed smoother as well. I got to notice some larger stars
that went by too quickly on the faster systems. On exit it
throws an error.
This program has performed an illegal operation
and will be shut down.

Fixed point vs Float Point. This is a final example with palette :thumbsup:
Smooth :thumbsup:
Did you use 16:16 fixed point?
Hi, Marinus, I have scaled by 2^16, nevertheless, it is so smooth due to the palette usage, though the fixed point seems to be better than float point. I will upload the samples in my fifth chapter.
Fixed point arithmetic is very useful if you want to prevent rounding and drifting errors, e.a. in audio re-sampling.

Hello, this days I'm doing some examples on ODBC accesing to db, access and oracle. I have already had success, and now I am rewriting the code to polish it.
The mdb accessing has this look:

For it, I have made previously a mdb db with the Oracle alike emp table, whose structure is this:
create table emp(
empno number(4,0),
ename varchar2(10),
job varchar2(9),
mgr number(4,0),
hiredate date,
sal number(7,2),
comm number(7,2),
deptno number(2,0),
constraint pk_emp primary key (empno),
constraint fk_deptno foreign key (deptno) references dept (deptno)
);
Instead of using Microsoft Access, I have used MDB Viewer Plus, that is a free mdb viewer and editing tool. And I have fed it with some data.
I will rewrite then the oracle example.
As i sometimes use oracle SQORA32.dll directly, i needed a modified odbc32.def files.
Using the code to access mdb, already more structured, the access to oracle gives me an error, but debugging it goes fine :rolleyes:. Well, not everything was going to be easy.
You aren't going to believe it :toothy: I had fixed some bugs but I have missed an "int 3" in the code to debug it, that's what failed, removed it and everything seems to go right with the Oracle ODBC conn. I have made it in fasm, I'm going to do it also en others compilers.
Well, right, everything is ok now :thumbsup:

"Masm codigo" gives a 404. The attachment above is a standard windows template, it does not cover your taskbar demo.
When the page says "error 404" is because it doesn't find the object linked. In this case, it was my fault, I didn't write the "W" in "TaskWM01.asm". The source attached above is complete, you may drag and drop in the fasm editor and compile with F9, that's all, I just missed the "a.ico" file in the zip that is used in the source. Anyway, it should work the link now in my web page.

The key seems to be in that position of 1.
One more step done. As you already know, to connect to Oracle via ODBC you need a system DSN connection string, a username and a password. Instead of putting it directly in the code, I have created a combobox that I feed with the connection strings already created in the ODBC data manager and a user box and another for the password. When the "Connect" button is pressed, read from there to establish the connection. Once connected, you can disconnect or extract the data and dump it to the listview. In the Fasm program I was doing, I was stucked retrieving the information from the system DSNs to feed the combobox, so I switched to Masm, where I have been successful. The image you see is from the MASM version.
With this, the basic version of the connection to Oracle would almost be there. what would be left to do:
Implement superclass to be able to navigate between text boxes and buttons using tab.
A basic help system indicating what each thing is
This will be the basis for my final goal, which is to make a program that reads from two access files: acc_old, acc_new, and from an oracle database. The structure of the access files replicates the structure of the oracle database. Inside here are some LONG/BLOB fields that hold some code. The acc_new brings news in this code, while acc_old contains the original that helps us to find what specific novelty it brings and implement it in oracle. With the added difficulty that in Oracle you may have made your own changes to this code. And, furthermore, this code is historicized.
Depending on what comes in acc_new I will search acc_old and oracle and download everything to different folders and text files that contain said texts and thus be able to compare them easier from text files.
I am considering the possibility of also generating a mariadb or sqlite database to save all the recovered data, such as the name of the code, who it depends on, and the start and end date of existence, for each of the environments.
If I don't get bored before, I have here for a long time.
I would say that this basic project is already finished. Unfortunately it does not seem to be possible to use the help button with the minimize or maximize buttons in the standard title bar.
Is it a window or Dialog based application ?
Is IsDialogMessage() used with a Window app ?
QuoteThe title bar of the window includes a question mark. When the user clicks the question mark, the cursor changes to a question mark with a pointer. If the user then clicks a child window, the child receives a WM_HELP message. The child window should pass the message to the parent window procedure, which should call the WinHelp function using the HELP_WM_HELP command. The Help application displays a pop-up window that typically contains help for the child window.
WS_EX_CONTEXTHELP cannot be used with the WS_MAXIMIZEBOX or WS_MINIMIZEBOX styles.

Hello, here the full fasm source codes for odbc connecting to microsoft access files and Oracle. "db_access.mdb" file also included. The program runs a query from the "emp" table.
First you must connect to the data base, for it you have to provide some data:
- Access. mdb filepath that you may type in the editext or by using the openfile dialog button. Then click in "connect", if you previously didn't fill the filepath the program tells you and position you in the edittext for it. When you finally connect, the "get data" button will be enabled and you can click on it to get the data from de data base table emp dumped in the list view of the program. You may disconnect when you want and then the "get data" button will be disabled again.
- Oracle. You must fill the DSN choosing it in the combobox, the user and password. Then you will be able to connect to database, otherwise the system indicates you what reamains to provide and put you in the right place for it. When you finally connect to database, the "get data" button will be enable, the same action as in access.
You may change the position for every object in the program using tab button.
* Edited: A minor improvement and bugfixed on listview headers.
I have perfiled the program for my personal project based on the ODBC-conn basic programs that I did some days ago. The name of the mdb loaded (without its path) is added to the groupbox. When the Oracle-conn is achieved, every object in its groupbox is deactivated, except the button to disconnect. I am planning to add a progress bar also above the executing button. It should extract the source codes inside every db to text files, so they would be better examined.
I'm noticing that SQLExecDirect doesn't allow functions within a sentence. For example, "select format(dt_start, "yyyymmdd")" triggers an error. Has anyone experimented such inconvenient? In the end I don't worring about if, because I can easily do it by hand in asm, but it would easier that the query send me the result. I have tested "select {fn format(dt_start, "yyyymmdd")} as fecha" but doesn't work either.
For this project I'm thinking on a embedded data base, my first thought was on SQLite, but it is more than 500k dll for such a tiny project, it seems ridiculous. So I searched and found LMMD (https://en.wikipedia.org/wiki/Lightning_Memory-Mapped_Database), 64K. It seems quite sexy for this project, but I didn't know it, any knowledge out there?
I have three environments:
- Orig. Main.
- Prev.
- Dest.
Starting from Orig I want the find what object has changed in Prev and Dest, but also it may be some differences, so I have stablished the next statement:
- Orig: 1 = 0001b
- Prev: 2 = 0010b
- Dest: 4 = 0100b
In such a way that, for example, 1 + 2 = 3 = 0011b means that this object is in Orig and Prev environments. And I have to dump all this data to the db I use. This information is usefull to know what object is in which db. Which one has changed, which one has been deleted, which is new, so on.

Yes. You can use the static library but size is same because is an object, and you can't remove unused functions. Any way is nice :biggrin:
This is my first attempt on doing so, not very well yet
A bit better now, I think
Rotating Sphere + back face culling
Rotating cube
Source?
WIP - 20Kb
F1: Plane
F2: Cube
F3: Cylinder
F4: Sphere
F5: Torus
1: Wired
2: Wired + back face culling
3: Flat filled
4: Lambert shading
great :thumbsup:
back face culling also possible with import few hundred polys?
Of course :thumbsup:
I have added the Gouraud shading that is, basically, a color gradient over each triangle. The result is a softer shading. But still with some white streaks that I need to fix.
Hi, fist attempt on making the Apollonian Gasket

Hi caballero!!
I was trying to see how you solved z-order in 6.1.9.14. Atractor de Aizawa (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=6).But not, you don't solved (yet?).

@HSE. Short memory, sooooo, the truth is in the code
Something strange still remains :eusa_pray:

zbuffer simpler solution?

That is the solution that fails.
Ok, now it is correct. The point is that if you set the generating spheres by eye, the algorithm can cause gaps between the following spheres. The generating spheres must be perfectly tangent.
