Description Sven Gothel 2012-01-04 09:51:05 CET
Preliminary applets tests on new test machine showed that our GLSL examples
(GearsES2, etc) didn't render properly (only background color).

The shader-less examples work properly.

No exception thrown on Java console.

Comment 1 Sven Gothel 2012-01-05 19:30:40 CET
Running GearsES2 with "-Djogl.debug.DebugGL" discloses the GL error:

Exception in thread "main-AWTAnimator-1" javax.media.opengl.GLException: Thread[main-AWTAnimator-1,5,main] glGetError() returned the following error codes after a call to 
     GLUniformData[name pmvMatrix, location 22675456, size 4*4, count 6, matrix true, 
     data java.nio.HeapFloatBuffer[pos=32 lim=96 cap=96]]): 
  GL_INVALID_OPERATION ( 1282 0x502),

This happens right at GearsES2 shader initialization w/ proper values.

"-Djogl.debug.TraceGL" shows (until the GL error):

No rendering results with GLSL on Intel HD Graphics 3000 (i3 / Sandy Bridge) 

Turns out GLUniformData had a bug in calculating the 'count' of matrices, ie. it did not respect the 
given position of the buffer. Instead of 4 * 4x4 it passed 6 * 4x4 (PMVMatrix data).

This was tolerated by NV, AMD, ARM, .. driver, but not on Intel HS Graphics 3000 / Windows 7.
(Good stuff)

  - V-Sync seems not to work (>60fps, tearing)
  - Supports OpenGL 3.1
  - junit test result: All Passed (no failures)
