Looks interesting
I Want to mention this: In my previous post I considered the Loop / Blinn method. I now figured out that this method is apperently patented by Microsoft. This explains why there is no open source implementation. Fortunately it is not necessary anyway! Only if you want to directly provide your shader with quadratic and cubic path data.
If the path is flattened and something like SDF on linear segments is used instead, it could be easier to implement. Unfortunately I have no idea how. So in your method the SDFs of specific shapes are used. Does this mean you have specific calls and shaders for every signle variation of shapes?
I’m in search for a general method that can be applied to linear line segments, so that in the end juce::Path can be used for everyhing. This would make things a lot easier but is also necessary since the juce::Graphics use clipping regions. The only requirement: Everything is anti aliased. Something like this:
Path p = ... // rectangle, ellipse, polygon, line, anything !
Path clipRegion = ... // Graphics clipping regions
p = flattenPath(p); // Convert quadratic, cubic segments to linear
p = clipToShape(p, clipRegion); // Clip any shape to clipping region (Clipper Lib)
triangleData = polygonToTriangle(p); // Triangulation (poly2tri)
vertexData = prepareShader(triangleData); // Calculate SDF Vertex + Shader Data
Do you think this is possible purely with SDF?
