internal cleanups to use luxinia2's core & math backends
removed lots of dead meat, reverted some unfinished changes to luxf3d and 3dsmax plugin
copy right notices...
Be aware not all stuff might work as it should. Older versions of
luxinia typically were much more "in use" by us, hence more stable.
And the refactoring to break out luxinia2's core libs might have
caused additional havoc. Xmas and Sparc runs ;)
added triarray collision test and fixed issues with raytri
added to allow vidbuffer→texcopy updates (optix interop)
added to allow custom function calls
removed as it was unused/untested
.datapointer was missing sarr pointer return
sarr was not updated properly
bugfix and added datalists for faster content traversal
work on textures and samplers (OGL 3.3) conform
and other state stuff
