| Summary | 0025350: Visualization - provide a dpi-scaling ratio for V3d_View | ||||
| Description | see: http://dev.opencascade.org/index.php?q=node/1002 Currently, Visualization layer in OCCT is currently dpi-unaware. This is a concern for for Retina displays on OS X, Windows (see also APIs introduced in Windows 8.1) and Android as well. Right now, an OCCT visualization on a mac book pro ( or the other platforms mentioned above ) do not provide hi-resolution OpenGL windows on hardware that supports these features. providing a global dpi-scaling in V3d_View would be a very welcome addition. this way, the application can react on events ( such as you mention moving from a hi-dpi to a conventional monitor ) and it would serve as a logical API call to manage hi-dpi resolution on any platform... | ||||
| Additional information and documentation updates | on Cocoa_Window's NSVIew, the setWantsBestResolutionOpenGLSurface method should be called for hi-resolution rendering, if supported by the hardware. however, as the discussion on the forum outlines, providing hi-dpi support is more involved. | ||||
