Member Function Documentation

void ShaderProgram::activate

(

)

Activates the current program for rendering, updating it's parameters.

void ShaderProgram::disableTextureParameters

(

)

Disables all texture parameters that have been set.

void ShaderProgram::enableTextureParameters

(

)

Enables all texture parameters that have been set.

void ShaderProgram::setParameter1f	(	string	name,
		double	valueOne
	)

Set a float3 parameter of one of the programs.

Parameters:

	name	name of the program
	valueOne	first float value

Remarks:

If no program of the given name exists or if the parameter is of a type different from float, the function returns without making any changes.

void ShaderProgram::setParameter2f	(	string	name,
		double	valueOne,
		double	valueTwo
	)

Set a float3 parameter of one of the programs.

Parameters:

	name	name of the program
	valueOne	first float value
	valueTwo	second float value

Remarks:

If no program of the given name exists or if the parameter is of a type different from float2, the function returns without making any changes.

void ShaderProgram::setParameter3f	(	string	name,
		double	valueOne,
		double	valueTwo,
		double	valueThree
	)

Set a float3 parameter of one of the programs.

Parameters:

	name	name of the program
	valueOne	first float value
	valueTwo	second float value
	valueThree	third float value

Remarks:

If no program of the given name exists or if the parameter is of a type different from float3, the function returns without making any changes.

void ShaderProgram::setTextureParameter	(	string	name,
		unsigned int	value
	)

Sets a texture parameter of one of the programs.

Parameters:

	name	name of the program
	value	id of the texture that is to be set as a parameter

Remarks:

If no program of the given name exists or if the parameter isn't a texture type (1d, 2d, 3d texture), the function returns without making any changes.
