public Class ARBTextureCompression

extends Object
Class Inheritance
Imports
java.nio.*, org.lwjgl.system.*
Native bindings to the ARB_texture_compression extension.

Compressing texture images can reduce texture memory utilization and improve performance when rendering textured primitives. This extension allows OpenGL applications to use compressed texture images by providing:

  1. A framework upon which extensions providing specific compressed image formats can be built.
  2. A set of generic compressed internal formats that allow applications to specify that texture images should be stored in compressed form without needing to code for specific compression formats.

An application can define compressed texture images by providing a texture image stored in a specific compressed image format. This extension does not define any specific compressed image formats, but it does provide the mechanisms necessary to enable other extensions that do.

An application can also define compressed texture images by providing an uncompressed texture image but specifying a compressed internal format. In this case, the GL will automatically compress the texture image using the appropriate image format. Compressed internal formats can either be specific (as above) or generic. Generic compressed internal formats are not actual image formats, but are instead mapped into one of the specific compressed formats provided by the GL (or to an uncompressed base internal format if no appropriate compressed format is available). Generic compressed internal formats allow applications to use texture compression without needing to code to any particular compression algorithm. Generic compressed formats allow the use of texture compression across a wide range of platforms with differing compression algorithms and also allow future GL implementations to substitute improved compression methods transparently.

Promoted to core in OpenGL 1.3.
