Hi Conan,
(I have the impression your name is a pseudonym, I wonder why... ;-)
[dumbquestion]
I am integrating some cuda into my osg app and one call requires the texture
name/id. How do I get that from my texture object? I look through the source
code and only found and id method in TextureObject, but my attempts to
retrieive this bit of data eludes me.
[/dumbquestion]
Not a dumb question at all, part of learning how to use OSG is learning
how the things fit together and what to do to get to the information you
need...
From an osg::Texture* (Texture2D, etc.) you have access to the
interface of osg::Texture (which Texture2D et al are subclasses of). But
first, to get to your OpenGL texture ID for a given Texture2D, you need
the context ID in which you want to get that information, which you can
get for example from the GraphicsContext like so:
unsigned int contextID = gc->getState()->getContextID()
Then you can do:
GLuint textureID = texture->getTextureObject(contextID)->id();
to get the ID of the texture object in that context.
Hope this helps,
J-S
