Member Function Documentation

SetBackfaceCull()

void chrono::ChVisualShapeFEA::SetBackfaceCull ( bool  mbc )

inline

Set backface cull speedup (default false).

Must be set true for shells and in general where already double-sided twin triangles are used.

SetBeamResolutionSection()

void chrono::ChVisualShapeFEA::SetBeamResolutionSection ( int  mres )

inline

Set the resolution of beam triangulated drawing, along the section (default: 10).

For example, in case of a circular section, this is the number of points along the circle.

SetShellResolution()

void chrono::ChVisualShapeFEA::SetShellResolution ( int  mres )

inline

Set the resolution of shell triangulated drawing (default: 2).

This value represents the number of visualization mesh vertices on each FEM element edge. The default value of 2 results in a visualization mesh constructed using only the FEM nodes.

SetSmoothFaces()

void chrono::ChVisualShapeFEA::SetSmoothFaces ( bool  msmooth )

inline

Activate Gourad or Phong smoothing for faces of non-straight elements.

Note: experimental feature.

SetZbufferHide()

void chrono::ChVisualShapeFEA::SetZbufferHide ( bool  mhide )

inline

Set the Z buffer enable/disable, for visualization systems that support it (default: true).

If hide = false, symbols will appear even if hidden by meshes/geometries.
