Coordinate Scalar Field

Functionality

This node generates a Scalar Field, the value of which at each point equals to one of coordinates of that point. For example, this node can generate a scalar field generated by function S(x,y,z) = x.

Cartesian, cylindrical and spherical coordinates are supported.

Inputs

This node has no inputs.

Parameters

This node has the following parameter:

• Coordinate. The coordinate to use. The available values are:

  • X. Cartesian X coordinate. This option is the default one.

    

  • Y. Cartesian Y coordinate.

    

  • Z. Cartesian Z coordinate, or cylindrical Z coordinate - they are identical.

    

  • Rho - Cylindrical. Cylindrical Rho coordinate.

    

  • Phi. Cylindrical or spherical Phi coordinate - they are identical.

    

  • Rho - Spherical. Spherical Rho coordinate.

    

  • Theta - Spherical. Spherical Theta coordinate.

    

Outputs

This node has the following output:

• Field. The generated scalar field.
