alpha.8

Changelog:

• Performance up by 15-20%
• Rasterizer no longer traces the polygon's entire outline before filling in the horizontal pixel spans; instead, interpolates between edges

alpha.7

Changelog:

• Face normals
• Backface culling
• Performance up by 30-50% (esp. in scenes with heavy use of tiled textures or with large occluding polygons)
• More render output tests

alpha.6

Changelog:

• Increased performance by roughly 30%
• Added full viewport clipping
• Added per-pixel depth buffering (optional)
• Added perspective-correct texturing (optional)
• Added handling of non-unit-range UV coordinates (0 > x > 1)
  • Negative values will flip the texture
  • Values absolutely larger than 1 will wrap around
• PNG2JSON: Added optional toggle to set which source pixel color to interpret as transparent
• Laxed requirements of immutability on some data structures
  • E.g. meshes' rotation values are now mutable, so the mesh object doesn't need to be re-created every time

Known new issues:

• The renderer may fail - either fully or partially - to fill in the last row of pixels on the screen

alpha.5

Changelog:

• Interpolated near-plane clipping
• Auxiliary render buffers
• API reference documentation
• Inlining of asserts for less reduction in performance

alpha.4

Changelog:

• More documentation
• Affine texture-mapping
• A single distributable source file
• Some improvement to n-gon clipping: entire n-gons are no longer clipped against the near plane, as only individual vertices now get dropped if they clip, leading to a less jarring visual effect. Still no interpolation to create new vertices at the point of clipping, though
• PNG2JSON has the option to export to raw RGBA-8888
• Mesh(), ngon(), and render() now take most of their parameters as properties of an object you pass them
• You can now get some performance information as a return object from render() - how long the rendering took, etc. It's undocumented, at the moment, but you can look at the source to see what render() returns
• Performance is probably a little worse than in alpha.3

Notes:

• The Blender export script is still bad
• Asset workflow is so-so

alpha.3

Changelog:

• More documentation on how to use the renderer
• New 3d asset converters: Blender export script, PNG2JSON
• Textures have alpha
• Textures accept Base64-encoded 16-bit color pixels, for reduced file size
• Fixed camera rotation in render()
• Near plane is clipped against prior to perspective division, reducing artifacts from objects located behind the camera
• An n-gon's base color now modulates its texel colors
• Sin/cos use a lookup table, for added retro vertex wobble
• Performance is somewhat lower than in alpha.2

alpha.2

Changelog:

• Notable speedup to textured rendering
• Cleaned up the directory structure
• Added a performance tester
• Rewrote the unit tester

Notable lacks:

• No frustum clipping yet, so immersive 3d scenes aren't possible
• No alpha in textures
• Asset management still in its infancy

alpha.1

Initial release.
