I have some points in 3D but all points are in single plane. It can be any plane. Now I wanted to know the interior angle between any three consecutive points. How can I do so?

For example, I have three points (1,0,0),(0,0,0) and (-1,1,0) then I want the answer as 135 degree. But If I have the third point is (-1,-1,0) then the answer should be 225 degree.

Hi all. I want use photos captured by 3D cameras in Silverlight 3 or 4. I want use that photos like in maps.google.com. Is it possible to do with silverlight and if yes is there any book, tutorial, video or anything alse, from which I can learn how to use tham. Thanks. >>> More

Hi everybody, I'm currently reading the Mathematica Guidebooks for Programming and I was trying to work out one of the very first program of the book. Basically, when I run the following program: Plot3D[{Re[Exp[1/(x + I y)]]}, {x, -0.02, 0.022}, {y, -0.04, 0.042}, PlotRange -> {-1, 8}, PlotPoints… >>> More

Hi everyone! I'm a self-taught programmer with absolutely nil 3D programming experience.

As you can see here I'm about to start work on a 3d project for class. Do you have any useful resources/websites/tips/etc. on someone getting started with OpenGL for the first time? The project will be in C++ and accessing OpenGL via GLUT. Thanks! >>> More
