Class EXTTextureCompressionBPTC

java.lang.Object

org.lwjgl.opengles.EXTTextureCompressionBPTC

public final class EXTTextureCompressionBPTC
extends java.lang.Object

Native bindings to the EXT_texture_compression_bptc extension.

This extension provides additional texture compression functionality specific to the BPTC and BPTC_FLOAT compressed texture formats (called BC7 and BC6H respectively in Microsoft's DirectX API).

Traditional block compression methods as typified by s3tc and latc compress a block of pixels into indicies along a gradient. This works well for smooth images, but can have quality issues along sharp edges and strong chrominance transitions. To improve quality in these problematic cases, the BPTC formats can divide each block into multiple partitions, each of which are compressed using an independent gradient.

In addition, it is desirable to directly support high dynamic range imagery in compressed formats, which is accomplished by the BPTC_FLOAT formats.

Requirs GLES 3.0.
