public Class ARBSparseBuffer

extends Object
Class Inheritance
Imports
org.lwjgl.system.*
Native bindings to the ARB_sparse_buffer extension.

This extension adds to GL a mechanism to decouple the virtual and physical storage requirements of textures and allows an application to create partially populated textures that would over-subscribe available graphics memory if made fully resident. This extension provides like functionality for buffer objects, allowing applications to manage buffer object storage in a similar manner.

Requires OpenGL 1.5 or ARB_vertex_buffer_object.

If true, then pages contained in the specified range become committed and become physically backed. If false, then physical storage associated with the data store in the specified region may be freed and those pages become uncommitted. Newly committed pages have undefined content. However, redundantly committing pages does not alter their content.
