|
virtual |
Check if a texture is resident in a given context. If not, make it resident.
|
virtual |
Make a texture non-resident in GPU memory If canDelete=true, the function will try to delete the texture and return true if it succeeded in deleting the texture.
|
virtual |
Called from the GlDeleteObjectManager when the texture is about to be deleted.
|
virtual |
Checks to see if the given texture is GPU resident. If it is not a texture or not resident, then false is returned.
|
virtual |
Get the Gpu address of a texture.
check if the texture is in fact an OpenGL texture
|
virtual |
get a tracker since residency is per gc, there's a tracker per gc just get the first tracker in our map
|
virtual |
see comments for myTextureIsResidentMap.
|
protectedvirtual |
get or create the tracker.
