Particle density data.
<p>
The density depends on how close particles are to each other. The density values are normalized such that: <ol>
<li>
Particles which have no neighbors (no particles closer than restParticleDistance * 2) will have a density of zero. </li>
<li>
Particles which are at rest density (distances corresponding to restParticleDistance in the mean) will have a density of one. </li>
</ol>
<p>
The density buffer is only guaranteed to be valid after the particle fluid has been simulated. Otherwise densityBuffer.ptr() is NULL. This also applies to particle fluids that are not assigned to a scene.
