Hi,J.P.
suggested code don't works on OSG SVN geforce8600M GT
if I copy in the loop all works fine
so this code doesn't work
//Transmittance
data = new float[256*64*3];
f = fopen("data/transmittance.raw", "rb");
fread(data, 1, 256*64*3*sizeof(float), f);
fclose(f);
Transmittance_t = new osg::Texture2D;
Transmittance_t->setSourceFormat(GL_RGBA);
Transmittance_t->setSourceType(GL_FLOAT);
Transmittance_t->setFilter(osg::Texture2D::MIN_FILTER,
osg::Texture2D::LINEAR);
Transmittance_t->setFilter(osg::Texture2D::MAG_FILTER,
osg::Texture2D::LINEAR);
Transmittance_t->setWrap(osg::Texture2D::WRAP_T,
osg::Texture2D::CLAMP_TO_EDGE);
Transmittance_t->setWrap(osg::Texture2D::WRAP_S,
osg::Texture2D::CLAMP_TO_EDGE);
osg::Image* image_Transmittance = new osg::Image;
image_Transmittance->setImage(256,64,1, GL_RGB, GL_RGB32F_ARB,
GL_FLOAT,(unsigned char*)data, osg::Image::NO_DELETE);
Transmittance_t->setImage(image_Transmittance);
delete[] data;
and this code works fine
//Transmittance
data = new float[256*64*3];
f = fopen("data/transmittance.raw", "rb");
fread(data, 1, 256*64*3*sizeof(float), f);
fclose(f);
Transmittance_t = new osg::Texture2D;
//Transmittance_t->setInternalFormat(GL_RGB16F_ARB);
Transmittance_t->setSourceFormat(GL_RGBA);
Transmittance_t->setSourceType(GL_FLOAT);
Transmittance_t->setFilter(osg::Texture2D::MIN_FILTER,
osg::Texture2D::LINEAR);
Transmittance_t->setFilter(osg::Texture2D::MAG_FILTER,
osg::Texture2D::LINEAR);
Transmittance_t->setWrap(osg::Texture2D::WRAP_T,
osg::Texture2D::CLAMP_TO_EDGE);
Transmittance_t->setWrap(osg::Texture2D::WRAP_S,
osg::Texture2D::CLAMP_TO_EDGE);
osg::Image* image_Transmittance = new osg::Image;
image_Transmittance->allocateImage(256,64,1,GL_RGB, GL_FLOAT,1);
image_Transmittance->setInternalTextureFormat(GL_RGB);
float* dataPtr_Transmittance = (float*)image_Transmittance->data();
for(int i=0;i<256*64*3;i++)
{
*dataPtr_Transmittance++ = data[i];
}
Transmittance_t->setImage(image_Transmittance);
delete[] data;
...
Thank you!
Cheers,
Roman
