Long time listener, first time caller. I'm making a little hobby game in XNA, its about transport ships in space, analogous to container ships at sea. I need to be able to predict the encounter bet...

I am trying to make a 3D viewer for building models. We have the model loaded and are trying to make some sort of interaction with the model. Therefor we are using OrbiControls for rotating, pannin...

I have a black box function, f(x) and a range of values for x. I need to find the lowest value of x for which f(x) = 0. I know that for the start of the range of x, f(x) > 0, and if I had a value ...

Important note: this question has utterly no relation to "PhysX", which is a computer-game-physics system (useful for the physics in arcade games such as ball games, etc); PhysX is a system built-i...

I have a university project in which we are asked to simulate a satellite approach to Mars using ODE's and SciPy's odeint function. I manage to simulate it in 2D by making a second-order ODE into...

I'm trying to write a code that plots the elliptical paths of an object using the equation for the ellipse r=a(1-e^2)/(1+e*cos(theta)). I'd also like this data to be put into an array for other use...
