Hi Manta developers,

Firstly, great work on the ray-tracer. I am trying to compile under windows using Visual Studio 2008. Currently I get the compile error shown below. Do you have any suggestions for how to proceed? The source line in question is:

Model/AmbientLights/.svn/text-base/AmbientOcclusion.cc.svn-base:68:    pair<float, float> sortedSamples[num_directions];

The compiler doesn't seem to like the non-constant "num_directions" here. Please let me know if you have any suggestions.

Cheers,
Ray
