1.0

Changelog

• Numerous changes to the API (see the API reference for details)
• Some new render samples

0.4

Changelog

• Non-perspective-correct interpolation now corrects for perspective only along the Y axis, rather than none at all
  • This produces less severe texture warping, but still some of it, which may be the aesthetic you're looking for
  • About 10% faster than full correction, whereas the old method was slower than full correction
• Points and lines now have optimized raster paths
  • Wireframe rendering without depth buffering is 25% faster
• Point and line rasterizers now (or for now) ignore the fragment buffer
• Can now build a module-format distributable, in addition to the global variant
• Vertex shaders now receive the render state object as an argument
• Pixel shaders now receive only the render state object as an argument
  • You now need to manually pass useFragmentBuffer: true in the render options if a pixel shader intends to access the fragment buffer
• Rngon.color now has convenience aliases for CSS color names (e.g. Rngon.color.hotpink)
• matrix is now exposed in the public API
• Tweaked the presentation of various render samples, and added a texture-painting sample
• The first mip level of a texture is now a direct reference to the base texture data
• Refactored the API reference manual
• Refactoring of source code

0.3

Changelog

• Implemented a new unit tester
  • Unit tests no longer run against the public API, so internal units can be tested
• Backface culling now works with object rotation
• Polygon normals are now always transformed into world space regardless of vertex shading mode
• Polygons are now single-sided by default (backfaces are culled)
• End-user documentation was split into multiple files
• Cleaned up the Rngon public API
  • matrix, lerp, throw, material, and assert are no longer exposed in the API (matrix might be re-added in the future)
  • version.isProd is now version.isProductionBuild
  • version no longer includes .patch
  • Certain internal utility functions (like Ngon.perspective_divide) are no longer visible publically
• Verbified the property names of Mesh.transform
  • transform.scaling → transform.scale
  • transform.translation → transform.translate
  • transform.rotation → transform.rotate
• Tweaked a few render samples
• Internal code refactoring
• JS module source files are now suffixed .mjs instead of .js

0.2.0

Changelog

• Improved render performance in Google Chrome
  • +40% to wireframe rendering
  • +10~20% to fixed-pipeline rasterization
• Improved the interface of Rngon.light
• Trimmed the Rngon API by removing some unnecessary properties
• Rngon.matrix44 is now Rngon.matrix
• Some refactoring of source file names
• Small improvements and streamlining of the HTML of render samples
• Deprecated lookup table-based sin/cos functions for built-in Math sin/cos
  • Reduced production distributable size by about 30%

0.1.0

First post-beta release.

Changelog

Various changes since the previous release a year ago, too many to list. The API was fairly heavily modified, and render performance has in some cases doubled.

beta.5

Changelog:

• Changed license from GPLv3 to MIT
  • You should always check the source file(s) for any deviating licensing notes - for example, some of the asset files of the render samples may fall under different terms
• Improved performance (by 100+% in some cases)
• Added new render paths that are taken under certain conditions and which result in higher render performance
  • E.g. for affine-textured polygons when no alpha operations or shaders are specified
  • Will be documented at a later time
  • You can find the code for the render paths - with descriptions of their conditions - in /js/retro-ngon/base-modules/rasterize/
• API changes in the 'options' object passed to render():
  • Render modules now live under a 'modules' sub-object
  • The 'Function' suffix of the 'pixelShaderFunction' and 'vertexShaderFunction' properties was removed
• Added context shaders (they expose the renderer's underlying CanvasRenderingContext2D)
• Added raster shaders (experimental; allow you to override or enhance the rasterization of transformed polygons without replacing the entire rasterizer module)
  • The difference to pixel shaders is that pixel shaders are applied to the rasterized image whereas raster shaders are the code that produces the image in the first place
• Added experimental support for paletted rendering
• Various small improvements to the point, line, and polygon rasterizers
• Some reorganization of the source code directory structure
• Added an overridable 'surfaceWipe' render module (for customizing the way the screen is cleared at the beginning of each render tick)
• Added ability to pass target canvas to render() as an Element object
• Added some render samples
• Tweaked the render benchmarks a bunch
• The render samples no longer depend on PHP
• Removed Phong shading
• Replaced the Bash build script with webpack

beta.4

Changelog:

• Added ability to render into an off-screen pixel buffer
• Added threaded async rendering using Web Workers
• Added texture mipmapping
• Implemented proper point and line rendering
• Fixed freeze if render width or height was <= 0
• Gouraud shading no longer ignores all but the last of the scene's light sources
• Added an index page for render samples
• Added more render samples
• Added some lightmapping tools (work in progress)
• Added the Rngon.version property

beta.3

Changelog:

• Added vertex shaders
• Added Gouraud shading
• Added performance benchmarks (with FPS graphs)
• Pixel shaders now receive the camera's world position as an input parameter
• Added a few new pixel shader samples
• All render samples now use texture atlases, for improved loading times
• Points (1-gons) now render properly
• Made a few performance tweaks

beta.2

Changelog:

• Added pixel shaders
• Added partial polygon transparency via stippling
• Added lights and flat shading
• Added render option 'allowTransform' to disable vertex transformation
• Added some more render samples
• Overall render performance is down by about 10-20%

beta.1

First beta release.

Changelog:

• Added clamp and repeat as UV wrapping modes (n-gon material property)
• Fixed black border at right and bottom of rendered image
• Don't call window.alert() for anything by default
• Removed perftest 2 (not useful enough; will be replaced with another, similar test at some point)
