[Plib-devel] Sphere intersection tests, and ssgaSpheres.

[Bram S. <br...@sa...>]

Hello,

Attached is sphere_isect.cxx test program, which demonstrates the
difficulties I experience when trying to line up ssgaSpheres with
sgSpheres.

The test program shows a sphere, and a cube. If the sgSphere
intersects the cube, the sphere is rendered in red, else it is
rendered using a blue colour.

I need to scale the ssgaSphere to a very strange size before I
get results which are visually roughly correct.
