Building Renderers

RenderToolbox3 uses sampled spectra instead of RGB colors. This improves rendering accuracy, but requires the renderers to be build from source with a few modifications.

If you use OS X 10.6 or higher, you can get pre-built renderers from the RenderToolbox3 downloads page.

Or you can read on and try to build the renderers from source.
