Member Function Documentation

void cGLSLShader::uninitializeShaders

(

)

[protected, virtual]

Called when we need to clean up shaders; e.g. when new shaders are being loaded.

Uninitializes the ARB handles associated w/this object by calling the uninit methods for the program, fragment, and vertex handles

Reimplemented from cGenericShader.

int cGLSLShader::initializeFragmentShader

(

)

[protected, virtual]

Called to create a fragment shader from m_fragmentShaderString.

Initializes the ARB fragment shader handle associated w/this shader

Returns:

>=0 for success, <0 for error

Reimplemented from cGenericShader.

int cGLSLShader::uninitializeFragmentShader

(

)

[protected, virtual]

Called to clean up a fragment shader.

Uninitializes the ARB fragment shader handle associated w/this object

Returns:

>=0 for success, <0 for error

Reimplemented from cGenericShader.

int cGLSLShader::initializeVertexShader

(

)

[protected, virtual]

Called to create a vertex shader from m_vertexShaderString.

Initializes the ARB vertex shader handle associated w/this shader

Returns:

>=0 for success, <0 for error

Reimplemented from cGenericShader.

int cGLSLShader::uninitializeVertexShader

(

)

[protected, virtual]

Called to clean up a vertex shader.

Uninitializes the ARB vertex shader handle associated w/this object

Returns:

>=0 for success, <0 for error

Reimplemented from cGenericShader.

int cGLSLShader::initializeProgram

(

)

[protected]

Creates the shader program object.

Initializes the ARB program object associated w/this shader

Returns:

>=0 for success, <0 for error

void cGLSLShader::uninitializeProgram

(

)

[protected]

Cleans up the shader program object (detaches the shaders and deletes the object).

Uninitializes the ARB program object associated w/this shader

void cGLSLShader::enableShaders

(

)

[protected, virtual]

Called at the beginning of a rendering pass to enable shaders, must be over-ridden by subclasses

Implements cGenericShader.

void cGLSLShader::disableShaders

(

)

[protected, virtual]

Called at the end of a rendering pass to disable shaders, must be over-ridden by subclasses

Implements cGenericShader.
