I'm having some problems with speed in my chunk engine. I timed it out, and in its current state it takes a total ~5 seconds per chunk to fill each face's list.
I have a check to see if each face of a block is visible and if it is not visible, it skips it and moves on.
I'm using a dictionary (unordered…

If I get coordinates via
coords = get(0,'PointerLocation');
How can I convert them into points gotten via ginput?
i.e, I would like to get the same values from
coords = get(0,'PointerLocation');
coords=someConversion(coords);
As I would have gotten by calling
coords=ginput(1);
And clicking…

I am working with a hexagonal grid. I have chosen to use this coordinate system because it is quite elegant.
This question talks about generating the coordinates themselves, and is quite useful. My issue now is in converting these coordinates to and from actual pixel coordinates. I am looking for…

Here is the code (I am using ASIFormDataRequest…

i'm not sure how to solve the following problem:
i have a triangle with each of the three known vertex positions A,B,C being inaccurate, meaning they can each deviate up to certain known radii rA, rB, rC into arbitrary directions.
given such a triangle, i want to calculate how much the difference…

Hey, I'm trying to convert a function I wrote to generate an array of longs that respresents Pascal's triangles into a function that returns an array of mpz_t's. However with the following code:
mpz_t* make_triangle(int rows, int* count) {
//compute triangle size using 1 + 2 + 3 + ... n = n(n + 1)…

I am building a CAD-file converter on top of two libraries (Opencascade and DWF Toolkit).
However, my question is plattform agnostic:
Given:
I have generated a mesh as a list of triangular faces form a model constructed through my application. Each Triangle is defined through three vertexes, which…
