-<p>Particle systems reserve memory for a fixed number of particles - <em>PxParticleBase::getMaxParticles</em>. Each of these particles can be addressed with a fixed index throughout it's lifetime. The given range of indices is [0, <em>PxParticleBase::getMaxParticles</em>]. In order to support a dynamic amount of particles, particles are marked as being valid or invalid. This is achieved by two means: The valid particle range indicates the range within which particles may be valid. Outside that range all particles are defined as being invalid. Within that range valid particles are marked with the flag <em>PxParticleFlag::eVALID</em>. Alternatively PhysX provides a bitmap with each bit set corresponding to a valid particle within the valid particle range. The bitmap consists of an array of 32-bit unsigned integers with enough elements to cover the valid particle range.</p>
