Hello,
Most OpenGL 2.0 drivers support NPOT textures as Texture2Ds (without
using TextureRectangle ARB extensions) as per the OpenGL 2.0 spec. Yet
OpenSceneGraph still resized an NPOT texture to power of two
dimensions when used in a Texture2D, even when OpenGL 2.0 is present.
Why is this?
I tested this with a 1280x1024 image. Using osg::TextureRectangle, the
image is used in the texture as is. But using osg::Texture2D, I get
this message:
Scaling image 'data/texture1280x1024.jpg' from (1280,1024) to (1024,1024)
I notice this message comes from Texture::applyTexImage2D_load().
Should this (or the calling method) be updated to check for OpenGL 2.0
and not resize if it is present? I can volunteer for this if it is
desired.
J-S
