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 will also add the Expert plug-in.

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

This section contains the following topics:

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: Clicking this button restarts rendering of the object

Cloth Flag Geometry Settings

  • Tessellation direction U and V: Sets the tesselation 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: Clicking this button restarts rendering of the object

Cloth Flag Move Settings

  • Translate X, Y and Z: Use these to offset the position output, from the position values set for the container

  • Rotate X, Y and Z: Use these to offset the rotation output, from the rotation values set for the container

  • Scale: Use this to offset the scale output, from the scale value set for the container

  • Reinitialize: Clicking this button restarts rendering of the object

Cloth Flag Advanced Settings

  • Turbulence Speed: These factors decide how fast the direction of speed will oscillate

  • Turbulence Factor: These factors multiply wind speed

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

  • Damping: Specifies how much speed each vertex should lose

  • Simulation Quality: These buttons allow the designer to quickly reduce or increase 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: Clicking this button restarts rendering of the object
