public class DDSLoader
extends Object

Provides a means of loading texture data from DirectDraw Surface (DDS) files. Note: Currently, this class does not do any format conversions, so it will fail for formats not supported by the OpenGL implementation. We may need to decompress or swizzle textures in unsupported formats.

Nested Class Summary

protected static class

DDSLoader.Header The DDS file header.

Field Summary

protected static int	DDPF_ALPHAPIXELS Pixel format flag indicating that the texture contains alpha data.
protected static int	DDPF_FOURCC Pixel format flag indicating that the texture contains compressed RGB data.
protected static int	DDSCAPS2_CUBEMAP Caps flag indicating that the texture contains a cube map.
protected static int	DDSCAPS2_VOLUME Caps flag indicating that the texture is a volume texture.
protected static int	DDSD_MIPMAPCOUNT Flag indicating that the header contains a mipmap count.

Constructor Summary

DDSLoader()

Method Summary

protected static ByteBuffer	load(File file) Loads the entire file into a (direct, little-endian) byte buffer.
static void	load(File file, Texture1D texture, boolean border) Loads a 1D texture from the supplied file.
static void	load(File file, Texture2D texture, boolean border) Loads a 2D texture from the supplied file.
static void	load(File file, Texture3D texture, boolean border) Loads a 3D texture from the supplied file.
static void	load(File file, TextureCubeMap texture, boolean border) Loads a cube map texture from the supplied file.
