Detailed Description

Shader-related interfaces.

Definition in file shader.h.


Typedef Documentation

A "shader variable stack".

Stores a list of shader variables, indexed by it's name.

Definition at line 48 of file shader.h.


Enumeration Type Documentation

Possible settings regarding a techique tag's presence.

Enumerator:
TagNeutral  The tag is neither required nor forbidden.

However, it's priority still contributes to technique selection.

TagForbidden  Techniques were this tag is present are rejected to be loaded.
TagRequired  Techniques are required to have one such tag.

If at least one required tag exists and no required tag is present in a technique, it doesn't validate.

Definition at line 152 of file shader.h.


Function Documentation

static csShaderVariable* csGetShaderVariableFromStack ( const csShaderVarStack stack,
const csStringID name 
) [inline, static]
