3d Graphics for a Web Based Application

Hi, I've to create a Web Based Application, that amongst other things, includes the following tasks Loading a 3D model from a database. Display the 3D Model. Doing Inverse Kinematics computations to generate the series of steps for the model to move from an initial to final position. Display the animation in real time. The applicati...

Changing the playback speed of an animation entity

Hello, I have an entity that plays an animation that runs in my world at speed s = 1. Now starting with a specific time interval in my world it is possible for the animation to slow down, which means it plays at a speed s where: 0 < s < 1. This time interval is defined by the starttime ta and endtime tb. So if the time in my world rea...

Simulation of molecular dynamics in Python

I am searching for a python package that I can use to simulate molecular dynamics in non-equilibrium situations. I need a setup that can handle a fairly large number of molecules in a primarily kinetic theory manner, and that can handle having solid surfaces present. With regards to the surfaces, I would need to be able to create arbitra...

Representing robot's elbow angle in 3-D

I am given coordinates of two points in 3-D viz. shoulder point and object point(to which I am supposed to reach). I am also given the length from my shoulder-to-elbow arm and the length of my forearm. I am trying to solve for the unknown position(the position of the joint elbow). I am using cosine rule to find out the elbow angle. Here ...

Handling inverse kinematics: animation blending or math?

I've been working for the past four days on inverse kinematics for my game engine. I'm working on a game with a shoestring budget so when the idea of inverse kinematics came up I knew I had to make it such that the 3D models bones would be mathematically changed to appear to be stepping on objects. This is causing some serious problems ...
