10.1 General
10.1.1 Intel GMA graphics cards
Webots should run on any fairly recent computer equipped with a nVidia or ATI graphics card and up-to-date graphics drivers. Webots is not guaranteed to work with Intel GMA graphics cards: it may crash or exhibit display bugs. Upgrading to the latest versions of the Intel graphics driver may help resolve such problems (without any guarantee). Graphics drivers from Intel may be obtained from the Intel download center web site. Linux graphics drivers from Intel may be obtained from the Intel Linux Graphics web site.
10.1.2 Virtualization
Because it highly relies on OpenGL, Webots may not work properly in virtualized environments (such as VMWare or VirtualBox) which often lack a good OpenGL support. Hence, Webots may exhibit some display bugs, run very slowly or crash in such environments.
10.1.3 Collision detection
Although collision detection works well generally well, Cylinder-Cylinder, Cylinder-Capsule, IndexedFaceSet-IndexedFaceSet and IndexedFaceSet-Cylinder collision detection may occasionaly yield wrong contact points. Sometimes the contact points may be slightly off the shape, therefore causing unrealistic reaction forces to be applied to the objects. Other times there are too few contact points, therefore causing vibration or instabilities.
