Module: createTangentSpaceDebugPrimitive

Creates a Primitive to visualize well-known vector vertex attributes: normal, binormal, and tangent. Normal is red; binormal is green; and tangent is blue. If an attribute is not present, it is not drawn.
Parameters:
Name Type Description
options Object Object with the following properties:
Properties
Name Type Attributes Default Description
geometry Geometry The Geometry instance with the attribute.
length Number <optional>
 10000.0 The length of each line segment in meters. This can be negative to point the vector in the opposite direction.
modelMatrix Matrix4 <optional>
 Matrix4.IDENTITY The model matrix that transforms to transform the geometry from model to world coordinates.

Returns:
A new Primitive instance with geometry for the vectors.
