chrono::fsi::ChFsiVisualizationGL Class Reference


Run-time visualization support for Chrono::FSI systems.

Requires the Chrono::OpenGL module. Note that using run-time visualization for a Chrono::FSI system incurs the penalty of collecting positions of all particles every time the Render() function is invoked.

Member Function Documentation

◆ Render()

bool chrono::fsi::ChFsiVisualizationGL::Render ( )

Render the current state of the Chrono::Fsi system.

This function, typically invoked from within the main simulation loop, can only be called after construction of the FSI system was completed (i.e., the system was initialized). This function querries the positions of all particles in the FSI system in order to update the positions of the proxy bodies. Returns false if the visualization window was closed.

Implements chrono::fsi::ChFsiVisualization.

◆ SetParticleRenderMode()

void chrono::fsi::ChFsiVisualizationGL::SetParticleRenderMode ( RenderMode  mode)

Set rendering mode for SPH particles (default: SOLID).

Must be called before Initialize().

Reimplemented from chrono::fsi::ChFsiVisualization.
