How can I implement 3D physics in C++ graphics?

To implement 3D physics in C++, you can use libraries like Bullet or PhysX. They provide robust physics engines.

What are the key features of the Bullet physics engine?

Bullet offers features like collision detection, rigid body dynamics, and soft body dynamics, making it versatile for 3D graphics.

Can you give me a simple code example using Bullet?

Sure! Here's a basic setup:

#include <btBulletDynamicsCommon.h>

int main() {
    // Initialize Bullet physics
    btDefaultCollisionConfiguration* collisionConfig = new btDefaultCollisionConfiguration();
    btCollisionDispatcher* dispatcher = new btCollisionDispatcher(collisionConfig);
    btBroadphaseInterface* broadphase = new btDbvtBroadphase();
    btSequentialImpulseConstraintSolver* solver = new btSequentialImpulseConstraintSolver();
    btDiscreteDynamicsWorld* dynamicsWorld = new btDiscreteDynamicsWorld(dispatcher, broadphase, solver, collisionConfig);
    // Add your objects and simulate
}

This sets up the basic components.

What other libraries can I use for 3D graphics in C++?

Other popular libraries include OpenGL for rendering, SDL for window management, and GLFW for handling input.
