Hi Robert, Is your app event driven or frame driven? Event driven
Does your app have one scene graph, one view, one window? Yes Does your app have one scene graph, one view but multiple windows? Yes (for applications like video walls/ off-axis projections) Does your app have one scene graph, multiples views and one or more windows? Yes Does your app have multiple scene graphs, multiples views and one or more windows? Yes Do you open and close windows regularly in the life of your application? Yes (where a window is a viewport in a full-screen application) Do you need to integrate the OSG viewer functionality into existing windows? Yes Do you need to integrate the OSG viewer functionality into 3rd party windowing toolkits/applications(i.e. IE/Firefox)? Yes Do you need support for distortion correction/compositing? No (Done in hardware) Do you have availability of multiple/wish to use CPU cores? Yes (all our h/w uses multiple CPUz or cores) Do you have availability of/wish to use multiple GPU? Yes (the viewer must be able to run on the available single, Dual SLI and Quad SLI configurations) Other viewer related issues: The ability to frame lock multiple GFX cards together (like the nVidia G-sync cards). We often configure the size, FOV, Frame buffer, etc. of our views/windows based on the available hardware (like switching from single screen to a render wall). So a configuration file like the one in Producer is a requirement. Currently about 90% of our visual simulators run in full-screen (multi display) mode because of the VR type of applications. Resolutions range from 1k to 4k (Horizontal). Because we use more than the standard keyboard/mouse input devices and want to have support for these devices outside of osg we started to use OIS. So any event mechanism/ support for keyboard/mouse devices should be made optional.
