| Summary | 0007928: Forum 7411: Improved display lists management for the trihedron display | ||||
| Description | This improvement has been reported by Open Source community user Sangsu Lee on the Forum, see thread 7411: http://www.opencascade.org/org/forum/thread_7411 The idea is not to re-create display lists for drawing trihedron arrows each time a 3D view is updated. Instead, a map-like behavior could be implemented (unfortunately, available object-oriented map implementations cannot be re-used in C code of OpenGl package), with an OpenGL rendering context (GLRC) ID being a key, and a structure containing current geometrical trihedron parameters and current display list ID(s) being a data. When some of trihedron's geometrical parameters changes for the given GLRC, corresponding display lists could be replaced with new ones, and old ones deleted. During view updates, existing display lists could be re-used, with help of their IDs taken from the map. On 3D view destruction, it is necessary to take care of removing trihedron data for relevant GLRC. Original posting: ----------------------- Sangsu Lee: To OCC developers, I think this code can be improved. If we make the display lists only when it is made at first or user redefine the triedron, and just call the lists when redrawing, and destroy it in the v3d_viewer's destructor, it would be more fast and efficient. Currently, it is always recreated and deleted again and it is not so efficient. | ||||
