Hi,
I'm working on implementing VBSP lightmaps to OSG but I've come across a
problem, I'm not able to copy the image data the way I used to in this function:
Code:
Vector2 insert(int id, const Vector2& size, const BSPFile::LightmapLuxel*
luxels)
{
BSPLightmapNode* lightmapNode(lightmapNodeRoot.insert(size));
if(lightmapNode != NULL)
{
glBindTexture(GL_TEXTURE_2D, handle);
const Vector4& rect(lightmapNode->rect);
glTexSubImage2D(GL_TEXTURE_2D, 0, rect.x, rect.y, rect.z - 1, rect.w - 1,
GL_RGBA, GL_UNSIGNED_BYTE, luxels);
lightmapNode->empty = false;
return Vector2(rect.x,rect.y);
}
else
{
return Vector2(0,0);
}
}
I've looked around for the OSG alternative to this method but I've not found
anything useful. The osg::Image::copySubImage() function seems to be the right
way to go but I can't find a way to have the same control over offsets has
glTexSubImage2D() :?
Thank you!
Cheers,
Micael[/code]
