CompressedTexture

Creates a texture based on data in compressed form, for example from a DDS file.

For use with the CompressedTextureLoader.

Constructor

CompressedTexture(mipmaps : Array, width : Integer, height : Integer, format : Constant, type : Constant, mapping : Constant, wrapS : Constant, wrapT : Constant, magFilter : Constant, minFilter : Constant, anisotropy : Integer, encoding : Constant)

mipmaps — The mipmaps array should contain objects with data, width and height. The mipmaps should be of the correct format and type.
width — The width of the biggest mipmap.
height — The height of the biggest mipmap.
format — The format used in the mipmaps. See ST3C Compressed Texture Formats, PVRTC Compressed Texture Formats and ETC Compressed Texture Format for other choices.
type — Default is v3d.UnsignedByteType. See type constants for other choices.
mapping — How the image is applied to the object. An object type of v3d.UVMapping. See mapping constants for other choices.
wrapS — The default is v3d.ClampToEdgeWrapping. See wrap mode constants for other choices.
wrapT — The default is v3d.ClampToEdgeWrapping. See wrap mode constants for other choices.
magFilter — How the texture is sampled when a texel covers more than one pixel. The default is v3d.LinearFilter. See magnification filter constants for other choices.
minFilter — How the texture is sampled when a texel covers less than one pixel. The default is v3d.LinearMipmapLinearFilter. See minification filter constants for other choices.
anisotropy — The number of samples taken along the axis through the pixel that has the highest density of texels. By default, this value is 1. A higher value gives a less blurry result than a basic mipmap, at the cost of more texture samples being used. Use renderer.getMaxAnisotropy() to find the maximum valid anisotropy value for the GPU; this value is usually a power of 2.

Properties

# .flipY : Boolean

False by default. Flipping textures does not work for compressed textures.

# .generateMipmaps : Boolean

False by default. Mipmaps can't be generated for compressed textures

# .isCompressedTexture : Boolean

Read-only flag to check if a given object is of type CompressedTexture.

Methods

See the base Texture class for common methods.
