Surface mesh

../../../_images/surface_mesh_panel.jpg

This visual element controls the appearance of triangulated surface meshes, which are produced by the Construct surface mesh, Create isosurface, Dislocation analysis (DXA) or other modifiers in OVITO.

Surfaces meshes are typically closed, two-dimensional manifolds embedded in a simulation cell. If periodic boundary conditions are employed, the surface mesh itself can be periodic. For visualization purposes, such a periodic mesh is first converted to a non-periodic representation by truncating it at the simulation cell boundaries. OVITO has an option to render so called Cap polygons to fill the holes that would otherwise appear at the simulation cell boundaries where the surface is clipped.

Coloring mapping mode

Unless the surface already has explicit color information associated with it, you have the choice between a simple uniform coloring mode and a pseudo-coloring mode, which lets you visualize some local property associated with the vertices, faces or regions of the mesh.

Parameters

Transparency

The degree of transparency of the surface.

Smooth shading

Turns on interpolation of face normals to make the polygonal mesh appear smooth, not faceted.

Flip surface orientation

Reverses the orientation sense of the surface and generates cap polygons on the outside, not inside of the enclosed volume.

Highlight edges

Activates the rendering of wireframe lines along the edges of the mesh facets.

Cap polygons

This option enables the display of caps at periodic cell boundaries where the surface is truncated.
