Houdini 16.5 Nodes VOP nodes

Not VOP node

This operator performs a logical not operation on an integer value, returning 1 if the input is zero, and 0 if the input is non-zero.

On this page

This operator performs a logical not operation on an integer value, returning 1 if the input is zero, and 0 if the input is non-zero. Only one operand is accepted.

Typically, not is used as an input to conditional operators such as If and While.

Parameters

Bitwise Operation

Instead of any non-zero value being treated the same, the input is broken into individual bits and the operation performed on them.

Examples

The following examples include this node.

grass

This example simulates grass being pushed down by an RBD object. Fur Objects are used to represent the blades of grass and Wire Objects are used to simulate the motion. When a single Fur Object is used to represent the grass, neighbouring blades of grass will have similar motion. Additional objects with different stiffness values can be used to make the motion less uniform. When "Complex Mode" is enabled, two objects are used to represent the grass. The stiffness of each set of curves can be controlled by adjusting the "Angular Spring Constant" and "Linear Spring Constant" parameters on the corresponding Wire Objects.

volumeresample Example for Volume Resample geometry node

This example shows how to use the Volume Resample SOP to increase and decrease the resolution of a volume. It also shows how the different sampling options affect the quality of the resulting volume.
