WebA small and fast JavaScript library for extruding 2D polygons and polylines to 3D meshes. It depends on earcut to do triangulation. Features. Extrude polygons with holes. Extrude polylines with specific line thickness. Generate position / uv / normal / indices TypedArray. Support bevel style. Basic Usage. Install with npm. npm i geometry-extrude WebBrute force compute if a point is in the polygon by traversing entire triangulation todo: speed this up using either binary tree or prefix coding (filtering by bounding box of triangle)
