this would be nice to develop to 3d floormapping

[dedndave]

if i answer Yes to vertex processing, it says Can't create direct-3d device
if i answer No.....

[qWord]

if i answer No.....

Can you please test the attached program to see if the issue is fixed?
I've also add some lighting and the graph can be translated along the x and y axis by pressing CTRL while mouse dragging.

much better   :t



try using this image
it is a 256-color bmp
the palette index (0 to 255) is the height

that is AWESOME, Steve   :t

Hi Dave,

   Glad you liked it.  Here is the scene description / code that I used.
More complex than needed as I try to set up a right handed, Z up
coordinate system rather than the default left handed, Z forward
system.  Which is why the penny came out backwards I guess.
I think the include files are no longer used, so ignore them.

   I fire up the ray tracer every year or so to look at things.  See
http://www.povray.org for the current version.  I still
use the old version that came with the book I bought back when.
I tend to like hard copy documentation.

Regards,

Steve N.

thanks Steve - let me see what i can learn from it   :t

[Siekmanski]

Hi guys

Here are some D3D9 heigthmap examples without using the D3DX9 library.
Bitmaps are embedded.

Press F1 to toggle Fullscreen.

1. BMP of 64 by 64 with 4096 color vertices and 7938 polygons.
2. BMP of 128 by 128 with 16384 color vertices and 32258 polygons.
3. BMP of 256 by 256 with 65536 color vertices and 130050 polygons.

Had a lot of visitors at my house this weekend, so better late than never hahahaha....
I'll clean up my source code this week and post them.

@Dave, hope you wanted something like this.

[dedndave]

hi Marinus
thanks for trying, but on all three, i get "unable to create Direct3D Object"   :(

[Siekmanski]

 :(

And this one?
edit: new version

[dedndave]

that one flies   :t

very nice image, too

the "top" edge flashes as it rotates, but i suspect that could be easily fixed

[Siekmanski]

So it works now?

I like to now if there where others who downloaded the examples and have problems running the 3 examples.
So I can locate the error.

[dedndave]

yes - the 4th one works pretty well

if it helps, i am running XP SP3, prescott @ 3 GHz, 2 Gb ram
the video is intel 82915GV Express Chipset on the motherboard
for it's time, it was decent stuff, but it's time was about 8 years ago - lol

[Siekmanski]

Seems to be a "IDirect3D9::CreateDevice" BehaviorFlags issue. ( type of VERTEXPROCESSING )
Like to hear from the other guys who tested the examples and make a fix then.

The "top" edge flashes are probably the very sharp 1 pixel height difference.
I'll make an amplitude factor in my code so you can play with that.

[dedndave]

you might look at qWord's examples
he got around the issue by using software vertex processing, as opposed to hardware

[Siekmanski]

@Dave,

I changed the type to "software vertex processing" in the 4th example.
I'm searching for the best type of VERTEXPROCESSING on the videocard.

Can you test this one and tell me what vertex processing type you have?

[dedndave]

HAL software vertex processing

funny - i was just looking at that example
it was in with your include files on the old forum   :P
