Setting Up the Resampled Volume

To activate volume rendering, create a resampled volume derived part.

Volume resampling is a technique for rendering volume at a relatively low computational cost. A key element of this technique is the voxel, a pixel that represents volume in three-dimensional space.

In the dialog that you use for setting up a resampled volume derived part, the Voxel Count preview lets you decide how to balance quality and computing costs. A larger number of voxels produces better volume rendering, but takes more time. A smaller number saves time but reduces quality. The recommended starting voxel count is between 1 million and 10 million.

To create a resampled volume, right-click the Derived Parts node and select New Part > Resampled Volume...

In the dialog, set the following properties:


Property	Setting
Input Parts	Room, Fire
Cell Size to Voxel Ratio	1.0
Display	New Scalar Displayer

Accept the other default settings.

To see what the resampled volume looks like, and to get the voxel count, click Preview.
Beneath the Preview button, the voxel count appears: 3.5 million.
Click Create, then click Close.
A new derived part named Resampled Volume is created in the Derived Parts manager node.
