Basic Collision Detection Questions

[lesPaul456]

Hello,

I just downloaded Bullet Physics SDK, and I just have a few questions to help get me started.

1.) Does Bullet handle all of the collisions itself, or do I still need to handle collision response?
2.) Is there a simple way for me to visually debug collisions?
3.) Can someone provide me with a link, or some code, showing how to setup a simple scene for collision against two objects?
4.) Is anyone here familiar with DarkGDK, and if so, have you been able to implement Bullet with DarkGDK?

I don't expect to have all of my questions answered, but I wanted to ask just so I can feel more comfortable starting my projects.

Thanks!

Bullet is a physics engine and not just a simple collision library. So yes, it's fully capable to handle the collision response.

2.) Is there a simple way for me to visually debug collisions?

Don't know.

3.) Can someone provide me with a link, or some code, showing how to setup a simple scene for collision against two objects?

Have a look at the bullet samples and just learn a bit OpenGL(it's really easier to learn than D3D9) to visualize a simple physic scene, e.g. with 2 box shapes.

4.) Is anyone here familiar with DarkGDK, and if so, have you been able to implement Bullet with DarkGDK?

I am not familiar with it, but AFAIK DarkGDK is closed-source and the only way to use phyiscs with it is a physic engine called "Dark Physics". So try OpenGL
