Arrow using algebraic shapes

CustomAlgebraicShape - This example shows how to use SoAlgebriacShape.

DESCRIPTION:

This example demonstrates how to implement a custom algebraic shape by providing a shader file corresponding to a custom ray/shape intersection function. The custom shape represents an arrow which is composed by a cylinder and a cone. The shape of the arrow is designed by a set of user-controlled parameters that are forwarded to the shader slot.

USAGE:

The following user interface commands are possible:

Length	Change the global length of the arrow.
ConeRadius	Change the radius of the hat of the arrow.
CylinderRadius	Change the radius of the base of the arrow.
ArrowHead	Change the coverage of the hat of the arrow.
