If you render two anti-aliased boxes next to each other (i.e. they share an edge), will you see a thin line there, or a solid fill? Last time I checked, cairo-b

  Good question. If you use the fillRectangle method https://github.com/Const-me/Vrmac/blob/1.2/Vrmac/Draw/iDrawContext.cs#L20-L21 https://github.com/Const-me/Vrmac/blob/1.2/Vrmac/Draw/iDrawC... to draw them I think you should get solid fill. That particular API doesn’t use AA for that shape. Modern GPU hardware with their rasterization rules https://docs.microsoft.com/en-us/windows/win32/direct3d11/d3d10-graphics-programming-guide-rasterizer-stage-rules https://docs.microsoft.com/en-us/windows/win32/direct3d11/d3... is good at that use case, otherwise 3D meshes would contain holes between triangles. If you render them as 2 distinct paths, filled, not stroked, and anti-aliased, you indeed gonna see a thin line between them. Currently, my AA method shrinks filled paths by about 0.5 pixels. For stroked paths it’s the opposite BTW, the output is inflated by half of the stroke width (the mid.point of the strokes correspond to the source geometry). You can merge boxes into a single path with 2 figures https://github.com/Const-me/Vrmac/blob/1.2/Vrmac/Draw/Path/PathBuilder.cs https://github.com/Const-me/Vrmac/blob/1.2/Vrmac/Draw/Path/P..., in this case C++ code of the library should collapse the redundant inner edge and the output will be identical to a single box, i.e. solid fill. Will also render slightly faster because less triangles in the mesh.
