Detailed Description

a cone and a frustum to represent a spotlight.

vtkLightActor is a composite actor used to represent a spotlight. The cone angle is equal to the spotlight angle, the cone apex is at the position of the light, the direction of the light goes from the cone apex to the center of the base of the cone. The square frustum position is the light position, the frustum focal point is in the direction of the light direction. The frustum vertical view angle (aperture) (this is also the horizontal view angle as the frustum is square) is equal to twice the cone angle. The clipping range of the frustum is arbitrary set by the user (initially at 0.5,11.0).

Warning: Right now only spotlight are supported but directional light might be supported in the future.
