<div class="textblock"><p>Raycast-CCD manager. </p>
|
|
<p>Raycast-CCD is a simple and potentially cheaper alternative to the SDK's built-in continuous collision detection algorithm.</p>
|
|
<p>This implementation has some limitations:</p><ul>
|
|
<li>it is only implemented for <a class="el" href="classPxRigidDynamic.html" title="PxRigidDynamic represents a dynamic rigid simulation object in the physics SDK. ">PxRigidDynamic</a> objects (not for <a class="el" href="classPxArticulationLink.html" title="a component of an articulation that represents a rigid body ">PxArticulationLink</a>)</li>
|
|
<li>it is only implemented for simple actors with 1 shape (not for "compounds")</li>
|
|
</ul>
|
|
<p>Also, since it is raycast-based, the solution is not perfect. In particular:</p><ul>
|
|
<li>small dynamic objects can still go through the static world if the ray goes through a crack between edges, or a small hole in the world (like the keyhole from a door).</li>
|
|
<li>dynamic-vs-dynamic CCD is very approximate. It only works well for fast-moving dynamic objects colliding against slow-moving dynamic objects.</li>
|
|
</ul>
|
|
<p>Finally, since it is using the SDK's scene queries under the hood, it only works provided the simulation shapes also have scene-query shapes associated with them. That is, if the objects in the scene only use <a class="el" href="structPxShapeFlag.html#a6edb481aaa3a998c5d6dd3fc4ad87f1aa7fa4fea0eecda9cc80a7aaa11a22df52" title="The shape will partake in collision in the physical simulation. ">PxShapeFlag::eSIMULATION_SHAPE</a> (and no <a class="el" href="structPxShapeFlag.html#a6edb481aaa3a998c5d6dd3fc4ad87f1aabc7ec24b00ed57f3914482f0706c6273" title="The shape will partake in scene queries (ray casts, overlap tests, sweeps, ...). ">PxShapeFlag::eSCENE_QUERY_SHAPE</a>), then the raycast-CCD system will not work. </p>
