Summary0025758: Visualization, TKOpenGl - texture initialization fails on Intel HD 4600 in ray tracing test
DescriptionOn a computer with Core i7-4790 which has Intel HD 4600 graphics, test v3d raytrace bug24819 fails on activation of ray tracing with message:

vrenderparams -raytrace
TKOpenGl | Type: Error | ID: 0 | Severity: High | Message:

 The error message appears on the following system, but Ray-Tracing still works (on second frame):
  GLvendor    = 'Intel'
  GLdevice    = 'Intel(R) HD Graphics 2500'
  GLversion   = '4.0.0 - Build 10.18.10.3621'
  GLSLversion = '4.00 - Build 10.18.10.3621'


The minimum reproducing test case is to display point sprite in the scene:
pload MODELING VISUALIZATION
vvbo 0
vinit View1
box b 1 2 3
vsetdispmode 1
vdisplay b
vfit
vraytrace 1

vpoint p 0 0 0


On tested system GL_INVALID_OPERATION error appears within first call to glDrawArrays() of method OpenGl_Workspace::RunRaytraceShaders():
  myGlContext->core15fwd->glDrawArrays (GL_TRIANGLES, 0, 6);

However error is inadequate - the reasons listed in OpenGL documentation for GL_INVALID_OPERATION are not met in our case.

Empirically error message does not appear if GL_ARB_sampler_objects functionality is not used, or when sampler is set to Mipmap-based format (not GL_NEAREST or GL_LINEAR used for Mipmap-less textures) before rendering Ray-Tracing code (I suppose when FBO texture is drawn), e.g. add following line to OpenGl_Workspace::DisableTexture():
aSampler->SetParameter (*myGlContext, GL_TEXTURE_MIN_FILTER, GL_NEAREST_MIPMAP_LINEAR);


Dear Andrey,
could you please check if you have the same issue on your system. Comment out the line "if (theContext.core33 == NULL)" in the OpenGl_Sampler.cxx and try test case:
Standard_Boolean OpenGl_Sampler::Init (OpenGl_Context& theContext)
{
  if (theContext.core33 == NULL)
  {

Hello Kirill,

1. Your "minimum reproducing test case" is working: after command "vpoint p 0 0 0" the box disappears

2. Commenting out line 71 in OpenGl_Sampler.cxx resolves the problem

3. I do not see anything like aSampler variable in OpenGl_Workspace::DisableTexture(), thus could not try using SetParameter()...
