Public Methods

Method	Description
BeginLevelLoad ( ) : void	Mark all file based images as currently unused, but don't free anything. Calls to ImageFromFile() will either mark the image as used, or create a new image without loading the actual data.
BindNullTexture ( ) : void	Disable the active texture unit.
ChangeTextureFilter ( ) : void	Resets filtering on all loaded images. New images will automatically pick up the current values.
CompleteBackgroundLoading ( ) : void
EndLevelLoad ( ) : void	Free all images marked as unused, and load all images that are necessary. This architecture prevents us from having the union of two level's worth of data present at one time.
GenerateAlphaNotchImage ( idImage image ) : void
GenerateAlphaRampImage ( idImage image ) : void	Creates a 0-255 ramp image.
GenerateAmbientNormalImage ( idImage image ) : void
GenerateBlackImage ( idImage image ) : void
GenerateBorderClampImage ( idImage image ) : void
GenerateDefaultImage ( idImage image ) : void
GenerateFlatNormalImage ( idImage image ) : void
GenerateFogEnterImage ( idImage image ) : void	Modulate the fog alpha density based on the distance of the start and end points to the terminator plane.
GenerateFogImage ( idImage image ) : void	We calculate distance correctly in two planes, but the third will still be projection based.
GenerateNoFalloffImage ( idImage image ) : void	This is a solid white texture that is zero clamped.
GenerateQuadraticImage ( idImage image ) : void
GenerateRGB8Image ( idImage image ) : void
GenerateRGBA8Image ( idImage image ) : void
GenerateRampImage ( idImage image ) : void	Creates a 0-255 ramp image.
GenerateSpecular2DTableImage ( idImage image ) : void	Create a 2D table that calculates (reflection dot , specularity).
GenerateSpecularTableImage ( idImage image ) : void	Creates a ramp that matches our fudged specular calculation.
GenerateWhiteImage ( idImage image ) : void
ImageFromFile ( string name, TextureFilter filter, bool allowDownSize, TextureRepeat repeat, TextureDepth depth ) : idImage	Finds or loads the given image, always returning a valid image pointer. Loading of the image may be deferred for dynamic loading.
ImageFromFile ( string name, TextureFilter filter, bool allowDownSize, TextureRepeat repeat, TextureDepth depth, CubeFiles cubeMap ) : idImage	Finds or loads the given image, always returning a valid image pointer. Loading of the image may be deferred for dynamic loading.
ImageProgramStringToCompressedFileName ( string program ) : string
Init ( ) : void
LoadFromCallback ( string name, ImageLoadCallback generator ) : idImage	Images that are procedurally generated are allways specified with a callback which must work at any time, allowing the render system to be completely regenerated if needed.
LoadImage ( string name, System.DateTime &timeStamp, bool makePowerOf2 ) : Microsoft.Xna.Framework.Graphics.Texture2D	Loads any of the supported image types into a cannonical 32 bit format. Automatically attempts to load .jpg files if .tga files fail to load. Anything that is going to make this into a texture would use makePowerOf2 = true, but something loading an image as a lookup table of some sort would leave it in identity form. It is important to do this at image load time instead of texture load time for bump maps. timestamp may be NULL if the value is going to be ignored If data is NULL, the image won't actually be loaded, it will just find the timestamp.
LoadImageProgram ( string name, System.DateTime &timeStamp, TextureDepth &depth ) : Microsoft.Xna.Framework.Graphics.Texture2D
ParseImageProgram ( string source, System.DateTime &timeStamp, TextureDepth &depth ) : Microsoft.Xna.Framework.Graphics.Texture2D	If data is NULL, the timestamps will be filled in, but no image will be generated If both data and timeStamp are NULL, it will just advance past it, which can be used to parse an image program from a text stream.
