Cogl.Attribute.new_const_3f

function new_const_3f(context: Cogl.Context, name: String, component0: Number(gfloat), component1: Number(gfloat), component2: Number(gfloat)): Cogl.Attribute {
    // Gjs wrapper for cogl_attribute_new_const_3f()
}
  

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.
