| Summary | 0028487: Visualization, TKOpenGl - add option for rendering with lower resolution | ||||
| Description | In some cases users have unbalanced configuration - high-resolution display (e.g. 4K) within slow low-end graphics. In these cases, rendering any complex scene with native resolution might be done with too low FPS and bad viewer interactivity, and this issue can not be negated by other rendering options (e.g. complexity of scene/geometry can not be reduced). It is a common practice to reduce rendered image resolution at application side in case when hardware is not capable providing enough performance for rendering in full (native) resolution. Of course, it is also possible changing display resolution system-wide (e.g. using up-scaling implementation provided by monitor or GPU driver), but it is not always desirable - e.g. when application works in windowed mode or it is desirable rendering user interface within native resolution while keeping 3D viewer with reduced resolution. Therefore, it is proposed adding such option to OCCT 3D Viewer to cover such use cases. | ||||

Scale factor can be below 1.0 (lower resolution) or higher (as analog of super sampling), but can not be combined with MSAA settings. Draw Harness command vrenderparams has been extended with option -rendScale managing introduced option Graphic3d_RenderingParams::RenderResolutionScale. vcaps has been extended with option -useWindowBuffer for managing OpenGl_Caps::useSystemBuffer option. vrepaint has been extended with option -immediate for testing immediate layer redraw |
