Constructor & Destructor Documentation

Shader::Shader

(

const string &

path

)

Constructor. Loads shaders from files and compiles them.

When path is "hello", the files "hello.frag" & "hello.vert" will be loaded. Calls the init function with geometryShader flag set to false.

Author:

Thomas

Date:

15.12.2010

Parameters:

path	Full pathname of the file.

Shader::Shader	(	const string &	path,
		bool	geometryShader,
		GLenum	inputType,
		GLenum	outputType,
		GLint	maxOutVertices
	)

Constructor. Loads shaders from files and compiles them.

When path is "hello", the files "hello.frag" & "hello.vert" will be loaded. If the geometryShader flag is set to true, "hello.geom" will be loaded as well. If the flag is set to false, all arguments except for the path are ignored.

Date:

Parameters:

path	Full pathname of the file.
geometryShader	Indicates whether a geometry shader should be used.
inputType	Type of the OpenGL input primitive.
outputType	Type of the OpenGL output primitive.
maxOutVertices	The maximum number of out vertices in the geometry shader per primitive. If this value is set to 0, the maximum possible number of vertices is queried and set as the number of output vertices.
