C++ 2D pixel perfect collision detection libraries?

Question

what are the libraries available to do this which integrate with SDL and QT4 . Are there any existing packages in SDL or QT which allow for easy implementation of this?. I am looking for for an easy to use library that would allow me to have a functionality like this

a link to the Api/class example/tutorial which implements pixel-perfect collision detection in your stated library is what i am looking for.

Edit: Please check the above link to understand what i mean by pixel perfect.

Answer 1

Qt does provide collision test in its QGraphicsItem class. It supoorts path-based shapes. I am not sure if it works with your pixel requirement.

Answer 2

Take a look at this GameDev related post(Reni2D is C with OpenGL so it should fit OK with SDL).

In HAAF's engine they advertise it as coming soon, so maybe it's worth checking it out also.

Answer 3

I recomend you this Allegro Perfect Collision

Allegro.cc has a great helpful comunity.

Good luck!

Answer 4

PoxelColl provides pixel-perfect collision detection, and supports basic transformations like rotation and scaling. A C++11 port is supported, so it should be compatible with SDL and QT.
