TextureContext

from panda3d.core import TextureContext
class TextureContext

Bases: BufferContext, AdaptiveLruPage

This is a special class object that holds all the information returned by a particular GSG to indicate the texture’s internal context identifier.

Textures typically have an immediate-mode and a retained-mode operation. When using textures in retained-mode (in response to Texture::prepare()), the GSG will create some internal handle for the texture and store it here. The texture stores all of these handles internally.
