Cloth Flag

The Cloth Flag plug-in provides a simulation of an elastic vertex object. The vertex object can be configured with many different parameters. Most of the parameters depend on each other, and some must be set in conjunction with others. Adding the Cloth Flag plug-in to a container also adds the Expert plug-in.

Note: This plug-in is located in: Built Ins -> Geom plug-ins -> Dynamics

This page contains the following topics and procedures:

Cloth Flag General Properties

  • Wind Rotation, Elevation and Force: These three factors combined gives the speed and direction of the wind affecting the flag. The allowed values are:

    • Wind Rotation: From -720.0 to 720.0

    • Wind Elevation: From -90.0 to 90.0

    • Wind Force: From 0.0001 to 100.0

  • Gravity Direction: Vectors that define in which direction gravity is affecting the vertices of the flag:

    • U: Horizontal.

    • V: Vertical.

    • None: Gravity is not applied.

  • Pause: Setting Pause to On pauses all calculations performed and the animation in both the scene editor and On Air output.

  • Reinitialize: Restarts rendering of the object.

  • Tessellation direction U and V: Sets the tessellation in the two directions on the systems surface. Calculation time increases with more vertices.

  • Scaling U (width): Changes the width of the rectangle which is including the animated cloth without increasing the number of triangles.

  • Scaling V (height): Changes the height of the animated rectangle which is including the animated cloth without increasing the number of triangles.

  • Reinitialize: Restarts rendering of the object.

Cloth Flag Move Settings

  • Translate X, Y and Z: Offsets the position output using the position values set for the container.

  • Rotate X, Y and Z: Offsets the rotation output using the rotation values set for the container.

  • Scale: Offsets the scale output using the scale value set for the container.

  • Reinitialize: Restarts rendering of the object.

Cloth Flag Advanced Settings

  • Turbulence Speed: Determines how fast the direction of speed oscillates.

  • Turbulence Factor: Multiplies wind speed.

  • Elastic: Changes the elastic properties of the system. If set to 0.1, the rendered output has properties resembling latex, and at 1.0 more like cloth.

  • Damping: Specifies how much speed each vertex should lose.

  • Simulation Quality: Reduces or increases the number of calculations performed for the plug-in, for performance reasons.

  • Wireframe: Shows the wireframe for the plug-in.

  • Draw normals: Shows the normals for each triangle.

  • Draw force: Shows the appealing wind in color.

  • Reinitialize: Restarts rendering of the object.
