The Drag space warp is a particle motion damper
thatreducesparticlevelocitybyaspecifiedamount
withinaspecifiedrange. Thedampingcanbe
applied linearly, spherically, or cylindrically. Drag
is useful for simulating wind resistance, transfers
into dense media (like water), impacts with force
fields, and other, similar situations.
With each damping type, you can control the
damping effect along several vectors. The damping
is also affected by particle system settings, such
as speed.
Drag slows down a stream of particles.
Procedure
To creat e a Drag space warp:
1.
On the Create panel, click Space
Warps. Choose Forces from the list, and then
click Drag.
2. Drag in a viewpo
rt to create the space warp.
The space warp appears initially as a box within
a box, indicating that it’s using the default
Linear Damping mode.
3. To apply the damping spherically or
cylindrically, choose Spherical Damping or
Cylindrical Damping in the command panel.
Note: The position and orientation of the space
warp plays an important role for all three
damping types.
4. Change the settings for the current damping
type as necessar y.
