Raysect Changelog
=================
Release 0.5.4 (1 Oct 2018)
--------------------------
Bug Fixes:
* Spectrum class samples attribute is now publically accessible again, not readonly.
New:
* Optimised materials significantly by avoiding unnecessary memoryview creation, ~10-20% speedups depending on material.
* Optimised observers leading to less overhead per pixel.
* Added caching to 2D mesh interpolator evaluations.
Release 0.5.3 (30 Aug 2018)
---------------------------
Bug Fixes:
* Mesh load() not correctly populating vertex and triangle data arrays.
* Missing import guard for OpenCV camera, users no longer forced to install OpenCV!
* VTK importer no longer crashes when mesh name is None.
New:
* Pickle support added to all scenegraph objects. It is now possible to pickle a scenegraph.
* Mesh normals can be flipped during import/creation with new flip_normals argument.
* Optimised ImportanceManager gaining a 7% speedup for Cornell Box test case.
* Optimised method call in optical.Ray gaining a 2% speedup for Cornell Box test case.
Release 0.5.2 (7 Aug 2018)
--------------------------
API Changes:
* Etendue replaced with sensitivity in the observers. [#202]
Bug Fixes:
* Raysect now builds with Cython 0.28.
* Fixed pixel geometry changes not triggering a recalculation of the TargettedCCD pixel sensitivity. [#219]
New:
* Added MeshCamera. A camera that uses the triangles of a mesh as pixels. [#204]
* Added Spectral and Monochromatic 1D pipelines. [supporting #204]
* Added STL and OBJ mesh exporters. [#176]
* Added limited support for PLY and VTK mesh importing/exporting. [#209, #224]
* Added OpenCV camera. [#109]
* Added sub-sampling (anti-aliasing) to VectorCamera. [#222]
* Added masked samplers that allow users to limit the region being rendered. [#223]
* Added meta dictionary attribute to scene-graph nodes to allow users to attach their own data. [#218]
* Added is_identity() and is_close() comparison methods to AffineMatrix3D. [#199]
* Added angle() to vector objects to compute angle between vectors. [#205]
Release 0.5.0, 0.5.1 (7 Aug 2018)
---------------------------------
Bug Fixes:

* Added cosine weighted cone random vector sampler.
* Added cython utility for determining polygon winding order for n-sided polygons.
* Added triangulate2d function for splitting N-sided polygon into triangles.
* Added lerp and slerp functions to Vector3D.
* Added new utility methods to BoundingBox2D and 3D.
* Added AnisotropicSurfaceEmitter material.
* Added BoundingSphere3D.
* Added MeshPixel. A pixel that uses a mesh as a collecting surface.
* Added TargettedPixel. A pixel that fires additional samples at specific target primitives.
* Added TargettedCCDArray. A CCD that fires additional samples at specific target primitives.
