Description

A quaternion julia fractal, rendered with some early work-in-progress of a self-made renderer. The color is calculated from the interpolated surface normal at each intersection: color = (normal+(1,1,1))/2 The c parameter is linearly interpolated between a and b: a = -0.125 - 0.256i + 0.847j + 0.0895k b = 0.3145 + 0.8126i + 0.2125j - 0.6664k roughly ;) For more information on this refer to: 0) http://en.wikipedia.org/wiki/Quaternion 1) http://local.wasp.uwa.edu.au/~pbourke/fractals/quatjulia/ 2) http://graphics.cs.uiuc.edu/svn/kcrane/web/project_qjulia.html
