Does View class in Sketchup API have method for drawing concave polygon. I found no method for doing it.
Method draw of View class: view.draw GL_POLYGON
, @arr_vertex
can only draw convex polygon.
Any suggestions would be appreciated.
No, there isn't one. View.draw is basically straight-to-OpenGL drawing so it requires convex polygons. You'll need to tessellate the polygon into convex polygons yourself.
