Fail to run a depth peeling example

Martin
Hi,

Did any of you tried to run the dual depth peeling port of abokinsky ?

Running it fails on this line:
gl.glTexImage2D( GL2.GL_TEXTURE_RECTANGLE_ARB, 0,  GL2.GL_FLOAT_R32_NV, g_imageWidth, g_imageHeight, 0,  GL2.GL_RGBA,  GL2.GL_FLOAT, null);

Replacing GL2.GL_FLOAT_R32_NV by GL2.GL_RGBA16F avoids crashing (well crashes later with something seamingly different related to shade_fragment.glsl)

I'm running windows 7 64bits.
I first used 2.0 rc2 (http://jogamp.org/deployment/archive/rc/v2.0-rc2/) and then rc5 (http://jogamp.org/deployment/archive/rc/v2.0-rc5/) with similar result:

Hi

You get this error (invalid enumerant) because this format is not supported on your hardware.

Re: Fail to run a depth peeling example

Example is now working great!!

I finally could get rid of this error by specifying in Nvidia settings to always use GPU :/ For others look here:



Before finding this, I failed with some shader errors. I report them here for other developpers that may fail to run programs with shaders on similar laptop with alternative integrated GPU.

1) Trying to load shade_fragment.glsl, I got an error saying:
"ERROR: 0:25: 'fmod' : no matching overloaded function found - implicit conversion not allowed"
for this following line:
color.rgb = (fmod(i, 2.0) == 0) ? vec3(.4,.85,.0) : vec3(1.0);
By looking on the web it seams fmod really exists and is modulo function. Thanks to a #if in the shader code, I can execute another code block instead an continue to next error :)

2) In dual_peeling_peel_fragment.glsl, I got some errors, the first one saying:
"ERROR: 0:10: '' :  extension 'ARB_draw_buffers' is not supported"

Looking at a wikipedia article let me think ARB will be supported on a very limited subset of computers: "Most non-nVidia OpenGL implementations do not provide the nVidia ARB assembly extension and do not offer any other way to access all the shader features directly in assembly, forcing the use of GLSL even for machine generated shaders where assembly would be more appropriate."

Regards,
Martin

Those wishing to study depth peeling with this example can find it packaged as a standalone eclipse project with JOGL2 rc5 jars bundled:

Thanks.

As far as I know, no scenegraph smartly handles the GPU change at runtime, such changes should be prevented.

Re: Fail to run a depth peeling example

If you press 2 (that is you switch to "front to back peeling mode") is it still working?

Because on my pc it freezes and I dont see any exceptions in the console..

However no problem the dual depth peeling, weighted average and weighted sum mode (1, 3 and 4), but the front to back doesnt work..

Are you guys experiencing the same?

Please use jstack or jvisualvm to see why it freezes.

I cant see anything wrong, but I dont know if I am using it properly... would you mind taking a look to a snapshot?

This example is working great, no problem also with simple depth peeling

Thanks Martin
