I\'m writing a game which uses 3D models to draw a scene (top-down orthographic projection), but a 2D physics engine to calculate response to collisions, etc. I have a few 3D assets for which I\'d lik

I am implementing some math algorithms based on lists of points, like Distance, Area, Centroid, etc.Just like in this post: Find the distance required to navigate a list of points using linq
i have an array of points in 3d (imagine the trajectory of a ball) with X samples. now, i want to resample these points so that i have a new array with positions with y samples.
I want to find whether a point lies inside a rectangle or not. The rectangle can be oriented in any way, and need not be axis aligned.
I have 2 geometries A and B which I\'d like to combine like shown at the end of the following drawing:
This is a question that 开发者_开发知识库I was asked on a job interview some time ago. And I still can\'t figure out sensible answer.
Imagine a photo, with the face of a building marked out. Its given that the face of the building is a rectangle, with 90 degree corners.However, because its a photo, perspective will be involved and
I have a small contest problem in which is given a set of points, in 2D, that form a triangle. This triangle may be subject to an arbitrary rotation, may be subject to an arbitrary translation (both i
How can I find the point B(t) along a cubic Bezier curve that is closest to an arbitrary point P in the开发者_运维百科 plane?I\'ve written some quick-and-dirty code that estimates this for Bézier cur
