Creating a Polarizer

This page shows how to create a polarizer thanks to the Speos features Material and UV Mapping.

To create a polarizer:

  1. From the Design tab, create the surface and the origin of the polarizer.
  2. From the Light Simulation tab, create a material:
    1. click Material .
    2. In the 3D view, click , select the geometries on which to apply optical properties and click to validate.

      The selection appears in Geometries as linked objects.

    3. In General, set the Type to Volume & Surface properties.
    4. Set Use Texture to True.

      A surface layer is created under the material in the simulation panel and allows you to define the surface properties of the geometry.

    5. In Volume properties, set the Type to Opaque or None.
  3. In the Simulation tree, open the Surface Layer.
  4. In the surface layer, define the surface properties to be applied on the geometry:
    1. From the Type drop-down list, select Library.
    2. In File, double-click in the field to browse and load a .polarizer material.
      Note: You can create a *.polarizer file with the Polarizer Surface Editor.
  5. Create a UV mapping:
    1. click UV Mapping .
    2. In the 3D view, click , select the geometry on which to apply the current mapping and click to validate.
    3. In the first UV map, select the mapping Type you need.
    4. Define the Origin, Projection Direction and Top Direction according to the mapping type selected.
      Note: For more information, refer to Creating the UV Mapping.
The polarizer is created.
