分布点于体积内

The Distribute Points in Volume node creates points inside of volume grids. The node has two basic modes of operation: distributing points randomly, or in a regular grid. Both methods operate on all of the float grids in the volume.

属性

分布方法

• 随机:

  Distribute points randomly inside of the volume. The local point count is implicitly defined as a product of the global from the Density input and the local voxel value. This method creates a distribution that is not stable as the input volume deforms.

  栅格:

  Distribute the points in a grid pattern inside of the volume. At each grid point, the voxel value is used to determine whether to add a point.
