Hi, I am doing RTT using the following code:
Code: Image *image = new Image(); image->allocateImage(320, 200, 1, GL_RGBA, GL_UNSIGNED_BYTE); Texture2D *texture = new Texture2D(); texture->setTextureSize(320, 200); texture->setInternalFormat(GL_RGBA); texture->setImage(image); camera->attach(osg::Camera::COLOR_BUFFER, texture); viewer->frame(); (I am using an Image because I need to read the data back. I'll probably change this code to use a PBO in the future). I can see the following message in the console window: Scaling image from (320,200) to (256,256) Why? Is it that my current graphics card (GeForce 7900GS) doesn't handle non-power of two texture sizes (seems odd)? When I reach the "Scaling from image" code in OSG, I can see that _textureWidth and _textureHeight are 256,256... why?
