| Summary | 0030332: Visualization - RedrawImmediate don't apply view background color | ||||
| Description | V3d_View::RedrawImmediate() always fill white color even if the background color is black. The usage of RedrawImmediate is to boost performance to draw temporary objects. Is there any consideration to fill background color in immediate mode? this is a bug I think no matter any reason. | ||||

Provided description is unclear - please clarify and provide use case / test case. V3d_View::RedrawImmediate() is not intended drawing the viewer background at all - it is expected to be called after V3d_View::Redraw() in rare cases, where partial Viewer update is applicable (like dynamic highlighting, drawing AIS_RubberBand, etc.). |

Dear kgv, I have uploaded two files AndroidQt.h and AndroidQt.cxx, they are copied from sample AndroidQt and updated to reproduce this issue. I do some changes: 1. AndroidQt::sync() changes: The function myView->SetWindow() just be called when the window size are actually changed to improve performance. 2. AndroidQt::paint() changes: Replace function myView->Rotation() to myContext->MoveTo() to prepare a immediate redraw. 3. To reproduce the issue, please open a document and then move your finger on screen, the screen background will be white color. |
