Creating Silhouettes

You can create silhouettes, that is 3D wires, to compute the vision cones of objects that are inside a car, from the view point of the passengers for instance. In one shot, it computes reflect lines, extracts edges that define the contour and removes non-visible areas of the contour.

Before you begin: Create a 3D shape.
