Lighting primitives supported include distant point lights, spot lights and ambient lighting. These are the same lighting types supported by POV and RenderMan. Megahedron appears to offer similar functionality, although I didn't delve into this area much. One of the nicest features is the live animation capability. Wireframe displays, which can include hidden surface removal, can be run interactively.
Interactive displays can also make use of mouse and keyboard input to control the display.
There are examples provided that show exactly how this is done. Programmable Shading As with any 3D environment, modeling is not enough. A collection of stock shaders such as granite, ridged and cloudy is provided. If you're used to using BMRT, it is important to keep this in mind when using Megahedron image maps. The shading language is closer to the RenderMan shading language than POV-Ray's texturing commands.
