* Fix some includes.Tavian Barnes2010-04-271-0/+1
|
* Rename dmnsn_matrix_*_mul() to dmnsn_transform_*().Tavian Barnes2010-04-171-6/+6
|
* Add transformations to textures and pigments.Tavian Barnes2010-04-151-80/+51
| | | | | Also, object intersection callbacks are now responsible for handling their own transformations.
* Remove a bunch of errno.h includes.Tavian Barnes2010-04-131-1/+0
|
* Get rid of some duplication in csg.c, and fix missed add of dmnsn_epsilon.Tavian Barnes2010-04-111-163/+23
|
* Don't use dynamic memory for dmnsn_intersection's.Tavian Barnes2010-04-071-156/+166
| | | | Drops us from ~400,000 allocs to ~1000. Oops ><.
* Calculate CSG bounding boxes more accurately.Tavian Barnes2010-04-071-9/+3
|
* New dmnsn_malloc() function, and friends.Tavian Barnes2010-04-071-164/+84
| | | | | | I'm tired of checking for malloc failures everywhere, considering it never happens. So just bail out whenever it does. A lot of stuff is guaranteed to succeed if it returns now.
