guilded Posted March 18, 2006 Share Posted March 18, 2006 how would i go about making a glass triangular prism that refracts a light that is pointed at it? Quote Link to comment Share on other sites More sharing options...
markeh Posted March 18, 2006 Share Posted March 18, 2006 This site deals with radiosity as well but it also gives surface values for refracted glass I believe. You may want to make IOR or Index of Refraction somewhere between 1.5 and 2. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted March 18, 2006 Hash Fellow Share Posted March 18, 2006 I suspect that A:M will not actually break the light into different colors like a real prism would. Rainbow spectrums would probably need to be faked somehow. But you can make objects that bend light somewhat like a prism would. Quote Link to comment Share on other sites More sharing options...

It uses multipass while changing the "prism's" refractive index and colour within the same frame. The method works for animation - I've tried it. The settings he provides leaves the dispersed colours looking a bit muddy for my taste, but the principle is there. Don't expect the results to look like Pink Floyd's "Dark Side of the Moon" album art - that'll need different techniques. Quote Link to comment Share on other sites More sharing options...
