texture float), including support for linear filtering (OES texture half
float linear, OES texture float linear), are supported in order to pro-
vide more precise texture data for algorithms that require it, particularly those that
also make use of vertex textures. The DXT1 (EXT
texture compression dxt1),
DXT3 (ANGLE
texture compression dxt3), and DXT5 (ANGLE texture
compression dxt5) compressed texture formats [ANGLE 11] are also provided
to improve performance by using less texture bandwidth in the GPU and by reduc-
ing system and video memory requirements.
