VOP SOP
surface node
Contains a VOP network that can manipulate point attributes.
This node contains a VOP network (double-click the node in the network editor to go inside it) which can use SOP context VOPs to to manipulate attributes on geometry points. (To define a SOP using a (textual) VEX program instead of a VOP network, use the VEX SOP instead.)
If there are no points in the geometry, the network will not run.
See creating a VEX surface node type for more information.
This node is useful for creating “one-off” programs to manipulate geometry in a single surface network. To use a VOP network to define a reusable surface node type, see creating a VEX surface node type.
Parameters
|
Point group |
If you enter the name of a point group in the first input geometry in this parameter, only the points in that group will be affected by the VOP network. |
|
Number of threads |
The number of separate threads to use to evaluate the points. The default is no threading. Since Houdini evaluates the VOP network for each point in the input geometry, it can benefit greatly from threading on a multi-processor or multi-core machine. |
