C# 클래스 idTech4.Renderer.idMaterial

Material.

Any errors during parsing just set MF_DEFAULTED and return, rather than throwing a hard error. This will cause the material to fall back to default material, but otherwise let things continue.

Each material may have a set of calculations that must be evaluated before drawing with it.

Every expression that a material uses can be evaluated at one time, which will allow for perfect common subexpression removal when I get around to writing it.

Without this, scrolling an entire surface could result in evaluating the same texture matrix calculations a half dozen times.

Open question: should I allow arbitrary per-vertex color, texCoord, and vertex calculations to be specified in the material code?

Every stage will definately have a valid image pointer.

We might want the ability to change the sort value based on conditionals, but it could be a hassle to implement,

AddImplicitStages ( TextureRepeat textureRepeatDefault = TextureRepeat.Repeat ) : void	Adds implicit stages to the material. If a material has diffuse or specular stages without any bump stage, add an implicit _flat bumpmap stage. It is valid to have either a diffuse or specular without the other. It is valid to have a reflection map and a bump map for bumpy reflection.
AppendToken ( StringBuilder b, idToken token ) : void
CheckForConstantRegisters ( ) : void	As of 5/2/03, about half of the unique materials loaded on typical maps are constant, but 2/3 of the surface references are. This is probably an optimization of dubious value.
CheckSurfaceParameter ( idToken token ) : bool	See if the current token matches one of the surface parameter bit flags.

ParseMaterial ( idLexer lexer ) : void	Parses the material, if there are any errors during parsing the defaultShader will be set.
ParsePastImageProgram ( idLexer lexer ) : string
ParseSort ( idLexer lexer ) : void
ParseStage ( idLexer lexer, TextureRepeat textureRepeatDefault ) : void
ParseTerm ( idLexer lexer ) : int
ParseVertexParameter ( idLexer lexer, NewMaterialStage &newStage ) : void	Parses a vertex parameter. If there is a single value, it will be repeated across all elements. If there are two values, 3 = 0.0, 4 = 1.0. if there are three values, 4 = 1.0.
SortInteractionStages ( ) : void	Sorts the shader stages. The renderer expects bump, then diffuse, then specular There can be multiple bump maps, followed by additional diffuse and specular stages, which allows cross-faded bump mapping. Ambient stages can be interspersed anywhere, but they are ignored during interactions, and all the interaction stages are ignored during ambient drawing.
