\brief Particle density data.

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>
|
|
Particles which are at rest density (distances corresponding to restParticleDistance in the mean)
|
|
will have a density of one.
|
|
</ol>
|
|
|
|
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.
