v0.3.0-alpha.3

Added:

• Custom vertex shaders:
  • DrawTriangles<T> (draws triangles with a custom vertex type)
  • ICanvas.Fill() overloads which accept a VertexShader (see the RenderCube example)
• Compute shaders (via ComputeShader and Graphics.Dispatch)
• Vertex shaders accept custom vertex data via a field with a VertexDataAttribute
• Vertex shaders can pass values to the canvas shader (fragment shader) via a field with a VertexShaderOutputAttribute

Fixed:

• Reimplemented gradients as canvas shaders
• Shader array alignment issues
• Various other bugs and crashes

Known Issues:

• anti aliasing doesn't work when rendering to a texture
• jump statements cause shader compilation errors (early returns, continue, break, etc)
• Texture saving is not yet supported
• Self-Intersecting polygons are not triangulated properly

v0.3.0-alpha.2

Changes:

• Various Compiler bug fixes
• Added missing shader intrinsics
• Added Rounded Rectangle Rendering
• Fixed jagged edges on large circles
• Many, many more bug fixes

v0.3.0-alpha.1

This version of SimulationFramework is the first release to contain the new OpenGL graphics backed and shader compiler.
Check out the The Wiki for information on how to write shaders.

⚠️ ⚠️ ⚠️ This is a very early alpha release. Expect lots of bugs and missing features. ⚠️ ⚠️ ⚠️

Additions:

• Added the new OpenGL graphics backend
• Programmable shaders via CanvasShader and associated shader APIs
• Added ICanvas.DrawTriangles(Vector2[])
• Added ICanvas.DrawCodepoint(int)
• Added Angle.Between
• Added Polygon.IsClockwise, Polygon.Area, Polygon.SignedArea, and Polygon.Triangulate
• Added IFont.MeasureText()

Changes:

• Added an optional tint parameter to ICanvas.DrawTexture
• Removed the SkiaSharp graphics backend
• Removed TextBounds
• Reworked CanvasState
• ICanvas.MeasureText() now returns a Rectangle

Known issues:

• ICanvas.DrawRoundedRect is not yet implemented
• Gradient and Textured Fill modes are not yet supported
• Texture saving is not yet supported
• Early returns cause shader compilation errors
• Shader array alignment issues due with 12-byte types (like Vector3)
• Large text is blurry
• Large circles/arcs have jagged edges
• Self-Intersecting polygons are not triangulated properly
• Textures access is only supported in shaders through ShaderInterinsics.Sample
• CanvasState's property setters should not be public
