E.10.2 - Beam Straight I Shape Tessellated

Example overview

The various examples demonstrate the use of tessellated items with vertex list and index, and optionally normal list and index.

The example shows a straight beam with an I-Shape cross section being tessellated with a fine mesh. Figure E.A and Figure E.B display the rendering in a target application.

The example shows a tessellation without adding the normals at each vertex to the data set.

beam_straight_tessellated_reference-view_edges — Figure E.A — tessellated beam visualized with edges visible

beam_straight_tessellated_reference-view_shaded — Figure E.B — tessellated beam visualized without edges
