3. New rendering model - ray casted shadows and appropiate button to

set 'on' this option. Note that is non real time model, especially when

|
complex object is computed. I took effort to introduce accelerating

structure - AABB (Axis Aligned Bounding Boxes).. but it is disabled

1. New displaying model - texturing with bilinear filtering and transparency

simultanusly. Note that filtering is done only inside polygon. To better
|
|

quality of image there is a need to use floats coordinates of texture to pass

as arguments to single triangle rendering proc.

2. Optimizations.

3. SSE3 version runs correct on SSE2 cpus, but real phong, glass and

|

transparented texturing with filtering rendering models are disabled.
