Starting making one of the previous lesson quiz for a few compilers 32 and 64 bits
I have added some basic shapes using the standard GDI functions. Only in TinyC folder, the others is the same.
This is quite powerful in the sense that you can draw bitmaps on the fly than you can use in your own windows objects.
Really anyone interested? If so I don't like to speak to myself. Any feedback and code will be welcome.
PS. When maximize the smile face window it get quite slow. Fortunatelly it can be improved with our drawing routines.
QuoteReally anyone interested?
:t I am.
Always want to learn and see how routines are done by other people.
I think it is a cool idea to discuss the different methods to create one effect.
Demo effects are a great resource for building games too. ( many of the game techniques stem from Demos )
Hey caballero this is a great contribution, thank you :icon14:. I can't promise to be a good student, but surely i will have a look to the code when i get the time. You should keep with your courses when there are interest, i agree with that (that's also a good idea to make students better), but please don't delete what you upload, is good for the forum and when some people get the time to learn about this issue they will come here too. :idea:
I almos forgot. Though I don't like much PeekMessage, here is a way to use it and stabilizing the fps, painting the fps on the screen. Ie, a way to write text to the screen using standard GDI functions.
I know that there's a way to optimize it, maybe using the function Sleep, that decreases the resources used. But, no time to chase it. If anyone knows how to do it, would be nice to tell us :t
:icon14: This is great, thank you very much.
First shape made by hand. Bresenham lines
More on basic shapes: circles. Fractal of Apolonio.
And more with Aldus haza (https://youtu.be/dbc1ollRt_E). HIEEERBA.
Very interesting routine, thanks. 8)
cool,thanks 8)
Very nice :t
Hello, I'm moving my graphic tutos here (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=0&Lang=1&nivel=0&padre=0&accion=0). A work in progress.
Plasma made with poasm, 32 and 64 bits
Hello
I have started the third chapter (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=3&Lang=1&nivel=0&padre=0&accion=0) (palette) with two examples at the moment, if anyone interested. All the compilers have worked well for 32 and 64 bits, except GoAsm for the 64 bits plasma and the palette builder for 32 bits. NasmX also fails for both examples for 64 bits. If anyone find the problem, please, tell me, in other case, I will check it when I have time.
Regards
Keep working with Palette examples, here a classical bars demo in 32 and 64 bits, made in fasm.
The last example for palette: copper bars, widly used years ago in MS-DOS. Already uploaded to my site in the third chapter (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=3&Lang=1&nivel=0&padre=0&accion=0).
This time poasm version for 32 and 64 bits.

Ops, I almost forgot my old good friend worm demo. I finish copper bars for nasmx and goasm and incorporate this one too... when I have time. This one made with tinyc.
Thank you, daydreamer. :thumbsup:
nice
I read about you wannat go 3d
I am open for suggestions of different palettes,that is used for landscapes,LUT of colors use by heightmap
>that is used for landscapes
Yeah, you can move with cursor keys. :thumbsup:
> you wanna go 3d
Yes, I did
I have a lot of things that I will gradually uploading

Hello. Image files, this time bitmap 24 bits in resources. Reading it and dump its data image in an array. Also for pcx, tga and even for saving gif. The example is a bmp rotozoomer. It accepts any bmp file that you can drag and drop over the program window, don't use a big one, better a 200x200 for example. Don't pretend to be an image reader, just manage bmp, pcx, tga for our purposes.
Hello, I'm uploading the 4th chapter, for graphics files. At the moment only in the Spanish version (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=4), though I will upload it soon the English (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=4&Lang=1&nivel=0&padre=0&accion=0) one too.
Graphics files:
- BMP. 8 and 24 bits. Reading from files and resources
- TGA. 8 and 24 bits. Reading from files.
- PCX. 8 bits. Reading from file.
- PPM. 24 bits. Writing and reading from file. Using a little raytracing program for that.
- GIF. 8 bits. Writing to file. Using a little program to gerating it.
At the moment only for tinyc. I will make the rest when time permits.

Fix for TinyC example BMP8bitsWC01.c#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <stdlib.h>
#include <stdio.h>
...
// Variables globales
DWORD *pMainDIB = NULL; // line 48
...
*(pMainDIB+index) = *(DWORD*)(miBMP->data + k); // Lo pasamos a pantalla line 116
after that msvc, clang and Pelles C compiles it.
Hello
@HSE
Ok, thank you. I had to look where these files were :)
@TimoVJL
Yes, thank you. In fact, it should be this way, but I like more the other one:
*(pMainDIB+index) = (miBMP->data[k].Rojo<<16) |
(miBMP->data[k].Verde<<8) |
miBMP->data[k].Azul;
uploaded the fixed codes and bmp and tga versions for masm32 at the moment, and a 8 bitmap from resources also.
hello, I have uploaded nearly all the masm32 versions: readers for bmp, pcx, tga, ppm for files and in resources, 8 and 24 bits. Only lefts writing gif and the tiny raytracer. And the versions for the other compilers.

Hello, I have just uploaded my fifth chapter (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=5) about basic maths for 2d graphics. It is a work in progress that I have just started. The last point is for moving a point between 2 points in the screen in a straight way. If anyone want to try it before I upload more stuff in this chapter is welcome to do it. For the moment only in Spanish and only for TinyC. Regards.
Hola Caballero!
Me parece que no está muy claro que son los números complejos. A lo mejor ayudaría una nota que diga para que nos va a servir conocer los números complejos.
Aparentemente todavía no se puede descargar ningún código TinyC.
:thumbsup:
Bueno, gajes del directo :biggrin:, ya se pueden descargar. He explicado someramente lo que son los números complejos, en principio no quiero profundizar más para no liar al que lo lea, básicamente el cuerpo de los números complejos se corresponde con el plano real. Los vamos a usar para rotar un número, cuyo ejemplo está en el punto 5.1.3. como he indicado ahí, concretamente la circunferencia de la izquierda. :thumbsup:
Faltaría un cast: 108: pMainDIB[i] = (int) miPaleta[m];
Ya voy a entender lo de la paleta :biggrin:
:thumbsup:No tiene mucho misterio, pero es una herramienta muy potente para la programación de gráficos.
Hello, a simple stright line path example. Don't know if anyone want to try it

I really like your spirals,I tested move path between 2 points program and it works
Uploaded the stright line path source code in chapter 5.1.4.1. (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=5#LineaRecta)
I have updated the fifth chapter including (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=5#Circular) two path examples: circular and splines. Attached here one for the last one: 5 random generating points calculated each time the program starts.

Thank you for test it :thumbsup:
They work fine, as all your demos do on my Win 8.1 64 bit PC. :thumbsup:
Talking about paths, here a nice program that I found some time ago here (https://www.freebasic.net/forum/viewtopic.php?t=25301) that I have translated to tiny c, the original in freebasic flickers a bit.

maybe better to reorder math from simpler pythagoras and circlemaking sine and cosine to be before the more advanced rotation formula which is based on the previous its made from same radius on both the old angle and the new angle
good work with making that chapter :thumbsup:
Better show first Pythagoras than complex numbers and rotation? Maybe. Thank you anyway :thumbsup:
I have started the chapter of graphics demos, here is a "raining drops" demo. Note that the window is a 512x512 size that will facilitate me the calculation of random points through xorshifts functions. The use of the standard c rand function is heavy and would lead to a greater increase in CPU usage. In this case it is inappreciable. It may take me a little longer to start with this chapter because I would like to leave the asm versions of the previous ones.
Chapter 6 started here, only in Spanish for the moment
http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=6
:thumbsup:
This time a flag demo to show how useful may be the sine/cosine function. There's an interesting tricky here: though there are 360 degrees we can reduce them to 255 and play with binary functions (and) instead of divisions (module). This is a quite simple example too and is quite easy to design your own flag too.
Blobs Demo, 32 and 64 bits
Thank you caballero for these fascinating works. I'm reading your first posts and some chapters of Charles Petzold's book (Programming Windows - fith edition) are very useful for understanding any aspects of your work. Thank you very much !
Thank you to you. That is a really good book :thumbsup:
Blur effect is quite important because is used in many graphic demos. This sample is a bit more elaborated, uses blurring that gives a 3d sensation, observe the rhodonea path, and we are here I have added a text scrolling with pixel clipping and a tune in the background. Everything in 108kb uncompressed that could be 17kb compressed.
nice work Carlos :thumbsup:
how is your take on make simplest tunnel and more advanced?
:biggrin: Don't know if you refer to me, because my name is Alfonso, if this would be the case... I will focus this subject a bit later, you can get a good reference here:

thanks, I like your turning tunnel in other thread,but I think it can be made with a different approach,make curved tunnel in C and use break; in loop when detect its turned into hidden pixels
related to tunnels are star gate animation that start when you step thru it
I've just uploaded many of the examples for 6th chapter (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=6) at the moment only in Spanish. I have reduced the compilers to fasm, poasm and tinyc, I am too old to manage others that are basically the same. At the moment all of them are in tinyc and some in fasm, I will populate ASAP. Here the examples in tinyc.
Here the codes compiled for now.
Edited: all the demos for the sixth chapter up today

looks good,except when maximize maybe it would help to use "round pixels",in fireworks
your sine/cosine LUT inspired me to experiment and got spinning kinda Milky way
I think that the full screen fireworks do not look bad, obviously you could increase the resolution with a higher CPU load, the current version hardly uses it. Other demos of fireworks that I have seen make intensive use of the CPU.
I have tried to upload several images and programs for the sixth chapter but it seems that the server rejects them and I do not see the reason very well, maybe it is that I have exceeded some file limit or something (it is a freeware hosting)... I am already beginning to be older to fight with such stupid things.
If there is anyone there, I would appreciate if you could try the program that I attached here (which I have also tried to attach to my site). This is a bumpmapping demo, for this I have used a standard Windows font called "Impact". And this is where my doubt comes: if really everyone would have it in their system and if someone would appear in a way that exceeded the window boundaries.
You should move your mouse over the windows for the demo take effect. :thumbsup:
Regards
Apparently it's not possible to see anything... fortunately look like if my mouse have a lantern :biggrin: :biggrin:
Impact is here :thumbsup:

It runs here on Windows 2000. Impact font is

Hey!, thank you for your help, guys! :thumbsup:
Hello, I have updated the sixth chapter (http://abreojosensamblador.epizy.com/?Tarea=5&SubTarea=6#Plasma) for plasmas, static and dynamic. I attached here several samples related to plasmas:
- PlasmaEstaticoWC01. A static plasma example.
- PlasmaDinamicoWC01. The same as before, but this time is dynamic.
- PaletaPlasmaWF01. This program shows the palete used by the plasma. It is very useful to know if the palette is adecuated for so.
- CubeCTexPlasmaMModWC01. A 3d rotating cube with a dynamic plasma for corrected texture.
Any feedback would be welcome, as ever :thumbsup:
Regards
Hello, a note on dumping the palette structure miPaleta. TinyC allows to dump it as a integer, that in the end it is what it is, but strictly speaking it is a structure and it should be treated as is. So the right way to use it, that is what PellesC and others c expect is:
color = miPaleta[i].Azul | (miPaleta[i].Verde<<8) | (miPaleta[i].Rojo << 16);
This is the right way, more than casting it. I use in TinyC "color = miPaleta" because TinyC allows me to do so and it is smaller and smarter. With above you may loose a few cycles but don't believe that you could realize that.
Regards.

:thumbsup: Yeah
Edited: fixed a small gap in the movement
Quadratic Bezier curves explained. You can drag and drop any of the three nodes, but I have to improve its movement.
Talking about raytracing, here is a programming test in 46kb. It needs the earthmap.bmp file in the same folder to be executed. It takes a while to appear, meanwhile it is creating a ppm image file where you can see its development.
Great, very detailed!!
I've been developping the cylinder formulae for raytracing and they took me more time than I expected, but finally I've got it than it seems working, they are a bunch of formulae where you may lost easilly, here they are if anyone interested.
