Creates a new, 3 component, attribute whose value remains constant across all the vertices of a primitive without needing to duplicate the value for each vertex.
The constants (component0
, component1
, component2
) represent a 3 component float vector which
should have a corresponding declaration in GLSL code like:
[| attribute vec3 name; |]
unless the built in name "cogl_normal_in" is being used where no explicit GLSL declaration need be made.
