Member Function Documentation

◆ DestroyInstance()

void cloudViewer::visualization::rendering::EngineInstance::DestroyInstance ( )
static

Destroys the singleton instance, to force Filament cleanup at a specific time. Calling GetInstance() after this will re-create the instance.

◆ EnableHeadless()

void cloudViewer::visualization::rendering::EngineInstance::EnableHeadless ( )
