| Summary | 0024609: Revise consistency of immediate update mode in V3d_View | ||||
| Description | The TKV3d viewer features "ImmediateUpdate" flag, which main purpose is disabling view updates (internal data) + redraws (rendering) while a sequence of connected view modifications is performed. The goal of using the immediate update flag is to reduce number of internal data recomputations and to avoid flickering of view during a logical sequence of view commands. There are two general issues at the moment: - Some methods changing state of V3d view do not use or ignores the flag. - There are two similar methods updating the view: Visual3d_View::Update, Visual3d_View::Redraw. The "Update" is marked as deprecated, but still used for ImmediateUpdate. | ||||

|
Note that Redraw and Update have different purposes in current implementation: - "Update" of view recomputes HLR "view-dependent" structures. This operation is quite heavy when computed mode for view is turned on. Then the view is repainted. - "Redraw" of view repaints the displayed structures without any significant computation. |
