Detailed Description

CCGLProgram Class that implements a glProgram

Since

v2.0.0

Method Documentation

- ((__deprecated__) __attribute__

Deprecated alias for setUniformsForBuiltins

- (void) addAttribute:		(NSString *)	attributeName
index:		(GLuint)	index

It will add a new attribute to the shader

- (NSString*) fragmentShaderLog

returns the fragmentShader error log

- (id) initWithVertexShaderByteArray:		(const GLchar *)	vShaderByteArray
fragmentShaderByteArray:		(const GLchar *)	fShaderByteArray

Initializes the CCGLProgram with a vertex and fragment with bytes array

- (id) initWithVertexShaderFilename:		(NSString *)	vShaderFilename
fragmentShaderFilename:		(NSString *)	fShaderFilename

Initializes the CCGLProgram with a vertex and fragment with contents of filenames

- (BOOL) link

links the glProgram

- (NSString*) programLog

returns the program error log

+ (id) programWithVertexShaderByteArray:		(const GLchar *)	vShaderByteArray
fragmentShaderByteArray:		(const GLchar *)	fShaderByteArray

creates the CCGLProgram with a vertex and fragment from byte arrays

+ (id) programWithVertexShaderFilename:		(NSString *)	vShaderFilename
fragmentShaderFilename:		(NSString *)	fShaderFilename

creates the CCGLProgram with a vertex and fragment with contents of filenames

- (void) setUniformLocation:		(GLint)	location
with2fv:		(GLfloat *)	floats
count:		(NSUInteger)	numberOfArrays

calls glUniform2fv only if the values are different than the previous call for this same shader program.

- (void) setUniformLocation:		(GLint)	location
with3fv:		(GLfloat *)	floats
count:		(NSUInteger)	numberOfArrays

calls glUniform3fv only if the values are different than the previous call for this same shader program.

- (void) setUniformLocation:		(GLint)	location
with4fv:		(GLvoid *)	floats
count:		(NSUInteger)	numberOfArrays

calls glUniform4fv only if the values are different than the previous call for this same shader program.

- (void) setUniformLocation:		(GLint)	location
withF1:		(GLfloat)	f1

calls glUniform1f only if the values are different than the previous call for this same shader program.

- (void) setUniformLocation:		(GLint)	location
withF1:		(GLfloat)	f1
f2:		(GLfloat)	f2

calls glUniform2f only if the values are different than the previous call for this same shader program.

- (void) setUniformLocation:		(GLint)	location
withF1:		(GLfloat)	f1
f2:		(GLfloat)	f2
f3:		(GLfloat)	f3

calls glUniform3f only if the values are different than the previous call for this same shader program.

- (void) setUniformLocation:		(GLint)	location
withF1:		(GLfloat)	f1
f2:		(GLfloat)	f2
f3:		(GLfloat)	f3
f4:		(GLfloat)	f4

calls glUniform4f only if the values are different than the previous call for this same shader program.

- (void) setUniformLocation:		(GLint)	location
withI1:		(GLint)	i1

calls glUniform1i only if the values are different than the previous call for this same shader program.

- (void) setUniformLocation:		(GLint)	location
withMatrix4fv:		(GLvoid *)	matrix_array
count:		(NSUInteger)	numberOfMatrix

calls glUniformMatrix4fv only if the values are different than the previous call for this same shader program.

- (void) setUniformsForBuiltins

will update the builtin uniforms if they are different than the previous call for this same shader program.

- (GLint) uniformLocationForName:

(NSString *)

name

calls retrieves the named uniform location for this shader program.

- (void) updateUniforms

It will create 4 uniforms:

• kCCUniformPMatrix
• kCCUniformMVMatrix
• kCCUniformMVPMatrix
• kCCUniformSampler

And it will bind "kCCUniformSampler" to 0

- (void) use

it will call glUseProgram()

- (NSString*) vertexShaderLog

returns the vertexShader error log
