Highly skewed triangles - missed reflections - rays going outside the solid #75

Open krzysztofarendt opened 1 month ago

krzysztofarendt commented 1 month ago

For models with some highly skewed triangles (teapot.stl and cylinder.stl) rays occasionally go outside the solid. Probably due to insufficient numerical precision.

Tests show (cb34fac1f1417313624674bd2f09c3b3ff46fde5) that the triangle side length should be approximately >= 0.001.
