My TI-30 will be by my side forever. I need nothing else in life.

Say you have a target with a velocity on the x and y-axis and acceleration on the x and y axis. Now, you have a gun with a fixed muzzle velocity. The gun is being carried by something with a velocity on the x and y and acceleration on the x and y. How would I go about solving the angle required...

I'm getting there. I started off by thinking that if the mouse was at say, (0,0) then it would be a whole screen distance up and to the left so I would say distance x = Screen size - 0 and distance y = Screen size - 0 up until half of the screen. I realize now that this would only work at the...

Ok.. maybe I should have put my question a bit better, with a bit more info on what I need this for. What I have is an object, inside a screen, that is inside another screen. The object can move, and the screen inside the screen is partially-fixed onto the object. If I move the mouse to the...

How would you go about converting from a Cartesian coordinate plane to one where (0,0) is in the top left hand corner?

http://en.wikipedia.org/wiki/OGRE_3D I read up on Ogre 3D quite a while ago (a few years) and it was quite active then, and is most likely still quite active now. It is open source, and written in C++ so once again, you might want to also check that out...

You might want to check this out. http://www.ode.org/ It's a free, open source physics engine with a C/C++ API.
