What kind of 2D library? Graphics, or physics? or something else?

I like this book alot, it says collision detection, but it also has a lengthly intro to many of the concepts of simulated 'space...

It's easy enough to arbitrarily set the rotation point, e.g. this will work:


case 'E':
case 'e':
{
//Rotation of the red square.
glMatrixMode(GL_MODELVIEW_MATRIX);...

#include <vector>
#include <iostream>

int main ( void )
{
std::vector < int > myvector;
for ( int i = 0; i != 10; ++i ) {
myvector.push_back ( i );
}
int * myarray = &( myvector...

Of course it is possible; there is necessarily always a projection from object>screen coords and there is always a projection from screen>a subset of object coords on a plane parallel with the view...

Brute force isn't too bad.. you don't have to check every pair of pixels between the two sprites, you only have to check each pixel space to see if it's occupied twice, and that's not very costly (...

Are your transforms 'full 3d' or 'half 3d'? That is, when your character rotates, can they rotate over all axes, or just around an 'up' vector? Are you using matrices as the authoritative...

Lines do not have ends: although a line is often uniquely defined by two endpoints coincident with the line; a 'line' is correctly considered to be infinite in both directions.

Line segments are...

Hey, sorry for the delay, been a bit busy.


Cool.


Well, it's open space graph, but the sparseness of the environment is a factor in choosing the method used to generate the graph... There...

Some questions to you:

- are you using the A* for AI character path planning? ( usual case ), is the 3D space unbounded? if so, are you ok with the fact that 3D A* search in infinite space will...

DirectX doesn't necessarily have better performance : it really depends how the graphics card manufacturers build their cards, and write their drivers. Without hardware acceleration, DirectX is...

For 2D point-in-convex or point-in-non-convex, see the crossing test on this page: http://www.erichaines.com/ptinpoly/. As its given there, that test will work in 2D only, for a 2D shape embedded in...

You need to represent a game company with development + release experience, and pay sums for a licence to get your hands on the official Wii SDK.

If you're talking about C# + XNA as being 'the...

This is good reference, http://www.gamasutra.com/features/19991018/Gomez_1.htm there are collision tests for different pairs of 3D objects ( see contents box on the right ). The tests would work in...

3D math and physics, artificial intelligence ( as it relates to games ), 3D graphics [ stay on top of all of the updates ], general programming skills, data formats, optimizing, and more... of...
