Pre 5.7 uses the FLEXlm licensing system for network license distribution. These license codes are not compatible with FLEXlm. Pre provides 3D graphics functionality on all supported workstations. Pre has 2 modes of 3D graphics operations. Software rendering and hardware rendering.
Software rendering is the default, although hardware rendering, if available, can be much faster.
Pre automatically detects the presence of a hardware graphics device. HKS recommends that you run the 3D driver in Hardware 3D mode if the workstation has a supported graphics option. Note that graphics acceleration is not applicable to remote displays except for homogenous OpenGL machines. Any other form uses the software 3D mode. See the specific hardware platform section in this chapter to find out if your graphics board requires a Z-buffered device or a layered software product.
