Hi Alphonso
I thought that i had nailed this one down, guess not.

Hi rCX
Not so much skill involved, im only a beginner.
I seen some of your posts and you are much better than i am.
I have only been playing with fasm for about a year or two.
Most of my experience is from writing Win32 and OpenGL apps in C/C++.
I have a nice game engine in these language so im porting little parts
of it to fasm syntax purely for the learning experience and for fun.
When i first looked at fasm sources i had no idea how asm worked
but i was farmilliar with Win32 so a lot of stuff was recognizable.
If it wasnt for these examples i would still be coding hello world apps.

I have made some changes to the timer code, maybe this helps?
Also some new changes made to the texture loading procedure.
There is now a 7 day poll for people who rather not respond by post.

Seems to be a problem with the exe in the package. When compiling the source it works great at ~670fps. Haven't tried with the new timer code as it is working fine now.

EDIT: Looking at the file dates the source is newer than the executable

Code:

27/05/2009  17:21               266 readme.txt
30/05/2009  10:22    <DIR>          API
30/05/2009  10:22    <DIR>          EQUATES
30/05/2009  10:22    <DIR>          TEXTURE
27/05/2009  17:34             9,728 fps.exe
13/02/2009  18:40               766 fps.ico
28/05/2009  15:40            25,524 fps.asm

Hope your not spending too much time to find coding problems that don't exist.

Hey thats funny, i may have had a mixup with all these files here.
Or maybe the zip was corrupted because they should be the same age.
I think this new version is going to produce some good results for people.
Anyway it seems that any of the changes i made are for the better.
So far so good on the poll, were at a solid 5 and 0. Razz

Hey,
nice!! Its amazing! it does not go very smooth, probably cuz im in safe mode lol
btw i use blender to make models, its awsome, and free.
blender.org
and it has a built in game engine Smile

New version!

Minor changes:

1) Rearranged code/data sections (some anti-viri complain)
2) App icon now loaded from exe resource instead of file.
3) New control, F1 key now minimizes the window.
4) Message pump and window proc changed to monitor window focus.
Now when the window loses focus it frees up CPU usage (dont be a hog)

Have fun Smile

Does anybody have a example of using openGL in 64 bit code?

maybe render will be better if you use 8 images for the walls instead of 4.

then, it will be an octogonal border instaed of square border, and render will be better.

there is a bug when exiting the program.

Code:

FPS caused a page fault in the module KERNEL32.DLL at 015f:bff7a128.
Registers :
EAX=0e829528 CS=015f EIP=bff7a128 EFLGS=00210206

thanks for this code.
i will try to play with for image rendering. Very Happy

see you later!

Sky-box is usually 6 images ±X±Y±Z
Where do you put these 8 images?
I can think of 14 images where there are 6+8 images. These extra 8 images are on each corner of the skybox to about 25% of the length/width/height.

...and the error happened on which OS, Service Pack, graphics card, RAM/CPU etc.

win98.
when i click the skull, it will redim the explorer window, and the mouse cursor will act as if it was in the skybox.
i presume a worse implemented hinstance or something like this. because if it works under win98, but bugs, it means there is a bug.
and for a better win application, i think the best is to do them always compatible for win98, because it is sure to work under earlier versions.

and for the skybox, i see this:

+X,+XZ,+Z,+Z-X,-X,-XZ,-Z,-Z+X

and the sky with only +Y,-Y

then, the horinzon will be an octogon. and angles will be smoother.

I liked it and it wasn't lagging like High Level Language compiled OpenGL programs.

You should make a game in asm.. It runs very smooth on my PC.

New version with minor changes...
1) Min processor now = Pentium PRO due to FPU instructions (fcomi,fcmov*)
2) Camera rotation math only recalculated during mouse movements.
3) Font generation code rearranged to shave a few instructions.
4) Perspective and Orthographic matrices now precalculated for later use.

NOTES:
1) Orthographic projection puts pixel [0][0] at top left unlike the standard OpenGL style with [0][0] at bottom left.
2) To use less CPU simply uncomment the Sleep call.
3) Some GPU do better with depth test enabled, others not.
If you get slow frame rates, try commenting glEnable,GL_DEPTH_TEST out.
4) Some GPU also do better with bitmap font, you can use my wgl Font code instead. Get it here: http://board.flatassembler.net/topic.php?t=9885
If people continue to show interest, i will continue to update the code...

Also, if a moderator could delete the POLL from this thread, thanks.

Wow I can't believe I never noticed this at all Shocked

Hey bitshifter, this is great! Are you making a full 3D game like this? It would be great, my netbook hits over 103 - 120 fps! So far its the fastest running 3D demo I have tried on it Very Happy

Maybe it will slow down when it begins to get more things to render...

< Are you making a full 3D game like this?
This is just a toy, my main project is a full-software driven 3D engine.
I really need resource developers for sounds/models/textures and such.

do you think it is possible without a lot of modification of your code to do the fps with this image?
http://fr.wikipedia.org/wiki/Fichier:Milkyway_pan1.jpg

it can be cool to have a universe fps, with accelerated time, then, we can see planet rotation.
