Changelog for traycer-hs

0.1

Initial release

0.2

Added better camera config. Now the camera can be positioned arbitrarily and in any orientation. See examples/Example.yaml.

0.3

Added transforms, but removed the camera positioning config as it can be emulated using transforms. Currently translation and rotation are supported. There are two kinds of transforms: object level and world level. See examples/Example.yaml.

Also added polyhedrons. It can now ray trace arbitrary convex polyhedrons. There is a convenience function for construction cuboids.

0.3.1

Polyhedron intersection is now accelerated using bounding boxes. The ray is first checked for interection with these bounding boxes before performing actual intersection test.

Fixed a bug where lights were not being transformed with the whole scene.

0.3.2

Minor refactor. Added rectangles to lessen the overhead of using cuboids to emulate ractangles, as the former has 12 triangles while the latter has only 2.
