Replaced most outdated BSD function calls with their posix equivalents, and cleaned up a few other platform dependencies.
Changed instances of "int4" to "int32" and "int2" to "int16"
Changes and check-in for 3.5 release Includes new source files and modifications not recorded for many years See ray/doc/notes/ReleaseNotes for notes between 3.1 and 3.5 release
Implemented sample quadtree in place of triangle quadtree Made geometric predicates more robust Added #define LORES which utilizes a single precision floating point sample array, the default is a double sample array Added topology DEBUG commands (for DEBUG > 1) Made code optimizations
sm.c, sm_del.c sm_ogl.c sm.h Fixed failure to tone-map on start up added code for temporary buffer allocation added bg flag, and fast flag checking routines for drawing provided graceful backout if deletion triangulation fails
new triangulation code changed triangle vertex order to CCW changed numbering of triangle neighbors to match quadtree fixed tone-mapping bug removed errant printf() statements redid logic for adding and testing samples with new epsilon
new triangulate routine added smTestSample to check for occlusion added frustum culling before rebuild changed base quadtree to use octahedron and created new point locate added "sample active" flags and implemented LRU replacement started handling case of too many triangles set sizes are now unbounded changed all quadtree pointers to quadtrees
fixed triangle insertion using edge tracing
