Class EXTTextureCompressionLATC

java.lang.Object

org.lwjgl.opengl.EXTTextureCompressionLATC

public final class EXTTextureCompressionLATC
extends java.lang.Object

Native bindings to the EXT_texture_compression_latc extension.

This extension introduces four new block-based texture compression formats suited for unsigned and signed luminance and luminance-alpha textures (hence the name "latc" for Luminance-Alpha Texture Compression).

These formats are designed to reduce the storage requirements and memory bandwidth required for luminance and luminance-alpha textures by a factor of 2-to-1 over conventional uncompressed luminance and luminance-alpha textures with 8-bit components (LUMINANCE8 and LUMINANCE8_ALPHA8).

The compressed signed luminance-alpha format is reasonably suited for storing compressed normal maps.

Requires OpenGL 1.3 or ARB_texture_compression.
