CC3GLSLVariableConfiguration Class Reference
| Inherits from | NSObject |
| Declared in | CC3ShaderSemantics.h |
Overview
A CC3GLSLVariableConfiguration carries information for configuring a single CC3GLSLVariable.
An implementation of the CC3ShaderSemanticsDelegate protocol will typically contain a collection of instances of this class, or a subclass, to configure the variables associated with a CC3ShaderProgram.
This base implementation maps a variable name to a semantic value. Subclasses may add additional variable configuration information.
Properties
name
The name of the variable.
@property (nonatomic, retain) NSString *nameDiscussion
Typically this is the name of the variable as declared in the GLSL program source code.
Declared In
CC3ShaderSemantics.hsemantic
A symbolic constant indicating the semantic meaning of this variable. See the description of the same property on the CC3GLSLVariable class for a full description.
@property (nonatomic, assign) GLenum semanticDiscussion
The initial value of this property is kCC3SemanticNone.
Declared In
CC3ShaderSemantics.hsemanticIndex
When the semantic refers to an element of a structure that may have multiple instances, this property indicates to which instance this variable refers. See the description of the same property on the CC3GLSLVariable class for a full description.
@property (nonatomic, assign) GLuint semanticIndexDiscussion
The initial value of this property is zero.
