Description
Moves particles as if each of them were rigid bodies. Particles will intercollide based on their shape and collide with the input obstacle objects. More specifically, the node updates the position, velocity, orientation, and angular velocity of particles based on the following attributes:
• PointPosition
• PointVelocity
• Orientation
• AngularVelocity
• Shape
• Size
• Scale
• StaticFriction
• DynamicFriction
• Mass
• Force
• Elasticity
The shape specifies the collision shape of the rigid bodies. Some shapes are approximated as follows: discs and rectangles are approximated as boxes; cones, cylinders and segments are approximated as capsules.
Parameters
|
Reference |
Reference to the geometric object to simulate. |
|
Explore |
Click to select the reference from an explorer. If the In Name port is connected, you can only choose references that are valid at the existing path. |
|
Pick |
Click to launch a picking session and select a reference from a viewport, explorer, or schematic view. |
Ports
Inputs
|
Mute |
Turns off the rigid body simulation. |
|
In Name |
Allows daisy chaining nodes to specify the reference. The scene path connected in this port is appended as a prefix to the reference string of the node. |
|
Collide |
Specifies whether the particles collide with each other and with the obstacles. |
|
Precision |
Specifies the maximum simulation frequency allowed. A precision of 60 means that the longest simulation substep would be 1/60 seconds. |
|
Active |
Specifies whether the obstacle collides with the particles. |
|
Geometry |
The obstacle geometry. The obstacle collision is approximated to the convex hull of the geometry. |
|
Elasticity |
The elasticity of the obstacle material. The elasticity is combined with the Elasticity attribute on each particle to determine how much each particle bounces off this obstacle. |
|
Static Friction |
The static friction of the obstacle material. The static friction is combined with the StaticFriction attribute on each particle to determine how each particle starts sliding on the obstacle when it is at rest. |
|
Dynamic Friction |
The dynamic friction of the obstacle material. The dynamic friction is combined with the DynamicFriction attribute on each particle to determine how each particle slides on the obstacle when in motion. |
Outputs
|
Simulate |
The port to connect so the node executes. |
|
Out Name |
Allows daisy chaining nodes. Connect this port into the In Name port of another node to prefix the reference of the other node with the reference of this node. |
