Given the image below
1. I have updated the image based on feedback from Steven_W so there are 4 triangles in the right hand diagram instead of 3 which makes more sense!
2. update image again to label sub triangles as A, B, C, D in grey
What is the pseudo...

Oh, you don't have triangle 415 in your.
Actually want to map points in the 4 triangles (125, 235, 435, 415) in your square box to the corresponding 4 triangles in your other square box (125, 235, 435, 415).

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?

Search for segment-segment interestion tests....
Alternately you could, assuming you know the edges, go through every triangle and delete those that cross an edge.
You shouldn't, you should find a Delauney routine that handles boundaries correctly .

But a generic answer is probably to use something like OpenGL, which is a portable API, and has Python bindings .
Well, that depends, very much, like which OS you are using, do you need to be portable, etc .

I suspect that you have some misconceptions about CUDA and how to use it, especially since you refer to a "process" when, in CUDA terminology, there is no such thing .

I have a file a.txt which is like:

These are vertices of triangles [x1 y1 x2 y2 x3 y3] that I need to plot on a 6x6 grid. I need to see these triangles on a single graph.
How can ...

Can use the PATCH function to accomplish this, although many of the triangles you have specified lay.

Hi
There are thousands of rays and triangles. We need get all the intersection points. If we use the normal two level loops,we need O(m*n) time complexity.Is there any way to low the time complexity fronm O(m*n) to O(m* logn) or O(logm*n)?
Best Regards...

You could group the triangles close to each other in cubes.
