public void reload ( ) { if ( mOriginalGeometry != null ) { if ( ! mOriginalGeometry . isValid ( ) ) { mOriginalGeometry . reload ( ) ; } copyFromGeometry3D ( mOriginalGeometry ) ; } createBuffers ( ) ; }
reload is typically called whenever the opengl context needs to be restored . all buffer data is re - uploaded and a new handle is obtained . it is not recommended to call this function manually .
