Справка Houdini на русском Shelf tools

Pump from Objects shelf tool

Gives fluid a velocity as soon it touches the pump.

This tool can be used to give fluid direction. It can also be used to create a spray effect, such as a fire hose.

Note

This tool only works with volume based fluid.

See fluid sourcing for information on how the tool transforms the input object into a source for the effect.

Using Pump from Objects

To...Do this

Create a fluid container

See Smoke Container, Flamefront Container, and Liquid Container.

Fill a fluid container

See Source from Surface, Source from Points, and Source from Volume.

Create a pump

  1. Click the Pump from Objects tool.

  2. Select the object to generate the velocity and press Enter.

  3. Select the fluid container and press Enter.

Control the added velocity

In the DOP network, find the Source Volume node importing the divergence field (named source_v_from_object).

Use the Scale velocity parameter to control the velocity. You can keyframe this value to delay and/or limit the pump time, pulse the pump, etc.

In the example below, the sphere is a liquid source, and the box is a pump:

Note

If no velocity is set on the pump, it will be turned off. To activate, navigate to the Velocity Volume tab on the create_v_volume node and turn on Add Uniform Velocity.
