[TUTO/DEMO] Static Ambient Occlusion (english)

[JeGX]

This topic aims to check off all the comments about the Static AO demo operating. The demo is available here:

Static AO Demo

This demo uses GLSL shaders (ambient occlusion, bump mapping, water reflexion) in an intensive manner as well as point_sprite particles.
So some weird behaviors might occur on some configurations. I've tested this demo on my geforce 7800gt and on a radeon 9800pro.
You can post any feedback here, the type of configuration, FPS and all other remarks.

In my case:

- winxp sp2
- p4 3.6GHz
- 1G ram ddr 400
- geforce 7800gt / forceware 81.95
- 246 FPS (without particles, only the demo initial screen)

and

- winxp sp2
- p4 2.6GHz
- 1G ram ddr 400
- radeon 9800pro / catalyst 5.11
- 96 FPS (without particles, only the demo initial screen)

Remark: in the demo, the vertical synchronization is enabled. You must disable it to measure the performances: just set vsync="FALSE" in the scene node.

Nvidia demo version (Static_AO_NVIDIA_Demo.xml) has the gl_ClipVertex variable in the AmbientOcclusiobLightingShader
and BumpMappingShader shaders. To test this version on ATI, you can edit the code and set nvidia="FALSE" in the check_hardware_caps element of the scene node. I'd like to know how the X700/X800 or the latest X1800 will work on the nvidia version...

Hi there,

I downloaded your Ambient Occlusion demo and installed Demoniak3D but for some reason it does not work on my system. My Graphics card is a nVidia Geforce 7800GS.
Do you have any ideas why It doesn't work?
