v0.3.0-alpha.13

• support for matrix array uniforms

SimulationFramework V3 alpha 12

many shader bugfixes

SimulationFramework V3 alpha 11

• Added support for multidimensional arrays in shaders (up to 4 dimensions)
• Added support for ImmutableArray<T> in shaders
• Added explicit array synchronization methods (via Graphics.SyncArray and Graphics.UploadArray)
• Added ThreadGroupSize attribute
• Added documentation for some new v3 apis
• Gradient now uses ImmutableArray<T>
• Internal compute shader and shader buffer handling improvements
• Fixed a shader invalid subgraph error when using chained && or || expressions in conditional statements
• Fixed a shader buffer binding error when using multiple buffers
• Updated Silk.NET and ImGui.NET to the latest available versions

SimulationFramework V3 alpha 10

• internal opengl bindings improvements
• fixed a bug where opengl functions that weren't required were being loaded
• shader compiler bugfixes

0.3.0-alpha.9

• fixed control flow related shader compilation errors
• added SoundPlayback.PitchMultiplier
• fix bug with line rendering using canvas.Fill()
• fixed Polygon.IsSelfIntersecting returning incorrect values
• fixed renderer bug when rendering large amounts of shapes

0.3.0-alpha.8

• readded ICanvas.DrawLines()
• many shader control flow bugfixes
• fixed drawing lines after calling ICanvas.Fill not working properly (#74)
• other small bugfixes/improvements

0.3.0-alpha.7

• Multiple Shader bug fixes
• Audio bug fixes
• ShaderIntrinsics.AsBool and ShaderIntrinsics.AsInt are now implemented

v0.3.0-alpha.5

Changes:

• instanced rendering
• mipmaps
• huge renderer improvements
• bigfixes

v0.3.0-alpha.4

• Shaders now support goto-like statements (break, continue, early returns)
• Started a renderer rewrite
• Added IMask:
  • allows per-pixel masking when rendering
  • can be written to and read from directly or filled in using a canvas (see IMask[int x, int y] and ICanvas.WriteMask)
  • Created using Graphics.CreateMask
• Added IDepthMask:
  • does everything a regular mask does, plus depth testing (useful in 3d rendering)
  • pass to ICanvas.Mask(IMask) to enable depth test. The IDepthMask.Comparison property configures the comparison used
  • pass to ICanvas.WriteMask(IMask) to enable depth write.
  • don't forget to call IDepthMask.Clear(1f) each frame before rendering!
• Started the IGeometry api:
  • an IGeometry is a read-only shape or model
  • can be created via Graphics.CreateGeometry and rendered using ICanvas.DrawGeometry
• renamed TileMode to WrapMode
• ITexture.GetPixel and ITexture.SetPixel are now obselete in favor of the new texture indexer ITexture[int x, int y]
• Fixed many, many bugs

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
