3d problems in LXBeams

Im doing something wrong with the 3d objects.
Cant figure it out so I made a 3 slide keynote and put it here:

Ps. I gave up on rendering with shadows after 5 minutes and hardly no progress. That didnt seem to be the problem anyway.

The cubes are inside out. Be sure that the start z height is greater than the end z. You almost certainly have it the other way around.

AHA!

That sure made a difference.

The shadows take a long time because each of those 3D boxes gets divided up into small squares and then the shadows are calculated for each one and then the composite lighting is rendered using the Open GL. A raytracing renderer might be faster depending on the level of detail. But, shadows are something that take time and that is multiplied by the number of light sources.
