Blurs the voxels of a volume.
The Volume Blur operation blurs the voxels of a volume.
It does this by computing for each neighbourhood around a voxel a single value according to some property of that neighbourhood. The resulting voxel is then set to that value. The neighbourhood regions are always cubic in shape, despite the term radius being used.
The volume primitives to be reduced.
|Use Voxel Radius|
Determine if the radius will be computed from world sizes or voxel sizes.
The world space radius to use for reduction. This defines the cubic region of voxels that will be valid for reduction. In the case of tapered volumes this is approximate as it the same voxel size blur will be used for all voxels.
With the exception of the median reduction, these reductions take about the same amount of time regardless of the radius.
The world space radius is converted to voxels, and this is then capped at 5x the voxel resolution.
The Maximum, Minimum and Median reductions only work on integer voxel radiuses.
The number of voxels to perform the reduction in along each axis.
The types of reduction to be performed.
An approximation of a gaussian blur can be achieved by doing four box blurs of smaller radius. For a cone blur, multiply the radius by 0.454545 and use two passes. For a gaussian, multiply the radius by 0.33 and use four passes.
