I have a concave polygon I need to draw in OpenGL. The polygon is defined as a list of points which form its exterior ring, and a list of lists-of-points that define its interior rings (exclusion z...

I have a set of vertices(called A) and I want to find all the border vertices such that this border vertices set is an outline of the shape. Many of the vertices in A are redundant because they a...

Ok, so I have a polygon (simple but concave) that I'm trying to cut into triangles to make it collide with an other polygon. I knew my polygone was concave, so i decided to use LibGDX EarClippingT...

I am a Bullet rookie, so I apologise in advance if my questions sound trivial to you. I need to load a set of concave triangle meshes from .stl files and perform collision detection. Objects can ...

I have a set of discrete points shown in an image, like the following I want to reconstruct or up sampling (I'm not sure what's the correct way to describe it) the image, so that the result image...

I've been scouring the internet for days, but have been unable to find a good answer (or at least one that made sense to me) to what seems like it should be a common question. How does one scale an...

i'm trying to get around the rule of only being able to form convex shapes in the SFML c++ library. To do this I'm planning on testing given vertices, and if concave, splitting the vertices in...

I'm using Delaunay to triangulate a concave polygon, but it fills in the concavities. How do I automatically remove the triangles that are outside the polygon boundaries?

I'm trying to draw a polygon using c# and directx All I get is an ordered list of points from a file and I need to draw the flat polygon in a 3d world. I can load the points and draw a convex sha...
