free resources

virtual void makVrv::DtFxOglParticleSystemRenderer::setup_particle_rendering ( int  render_pass_flags )

inlinevirtual

needed by base class, now no-ops so that render info can get passed in.

virtual void makVrv::DtFxOglParticleSystemRenderer::setup_particle_rendering ( int  render_pass_flags, osg::RenderInfo &  renderInfo  )

virtual

called at the beginning of the rendering. Render pass flags are from diguyApp mostly used to identify shadow vs main view

virtual void makVrv::DtFxOglParticleSystemRenderer::end_particle_rendering ( int  render_pass_flags )

virtual

called at the end of the particle rendering to clean up state

virtual

virtual DtFxParticleVertex* makVrv::DtFxOglParticleSystemRenderer::getMemoryPointer ( int  datasize )

virtual

maps a buffer from the gpu into user memory

virtual void makVrv::DtFxOglParticleSystemRenderer::unmapMemory ( )

virtual

unmaps the vbo data

virtual

draws a particle system

virtual void makVrv::DtFxOglParticleSystemRenderer::setCameraPos ( double  x, double  y, double  z  )

virtual

set the current position of the camera

virtual bdiFarPosition& makVrv::DtFxOglParticleSystemRenderer::cameraPos ( )

virtual

gets the current position of the camera

virtual DtFxGizmoRenderer& makVrv::DtFxOglParticleSystemRenderer::gizmoRenderer ( )

virtual

gets the debug rendering class
