Hi guys,
Rookie here and now I encounter two problems and turn to you for help.
1. Can I raster a polygon (both simple-polygon-2d-type and polygon-with-holes-2d-type) using CGAL? I can realize this myself, but I'm not satisfied with the speed.
2. Suppose I raster my polygon to a M x N grid. For pixel (i,j), I want to get its overlay area with this polygon. I try to create a polygon using the four corner point of each pixel, but the speed is a bit slow even when grid size is 150 x 150 of simple-polygon-2d-type, let alone the polygon-with-holes-2d-type situation.
Best regards!
