# Surface mesh display

This display object is responsible for rendering the polyhedral mesh that is produced by a Construct surface mesh modifier.

## Parameters

Surface color

  The rendering color of the surface.

Transparency

  The degree of transparency of the surface. Note that the default OpenGL renderer does not support semi-transparent objects yet. Thus, this parameter is currently used only by the Tachyon software renderer.

Smooth shading

  Enables the interpolation of normal vectors between vertices of the polygonal mesh (also known as Gouraud shading).

Cap polygons

  OVITO computes the intersection of the surface with the periodic boundaries of the simulation cell. Cap polygons are created to close the cut mesh again. This option enables or disables the display of the cap polygons.
