Linear-time CSG rendering of intersected convex objects

The Sequenced Convex Subtraction (SCS) algorithm is a hardware based multi-pass image-space algorithm for general purpose Constructive Solid Geometry (CSG) Rendering. Convex objects combined by volumetric intersection, difference and union are rendered in real-time without b-rep pre-processing. OpenGL stencil and depth testing is used to determine the visible surface for each pixel on the screen.
