All these drivers supports the display of animation using animation curves. Filters to convert data files created by IRIT to PostScript, DXF, SGI Inventor, NFF, REND386, Rayshade, SCN, and Xfig format. A coverage based on adaptive extraction of isocurves can be used for various purposes from toolpath for machining purposes to image rendering. This algorithm, that is exploiting symbolic computation, is implemented using the IRIT solid modeller and a tool named xgladap make use of the hardware of the SGI systems to provide real time rendering using adaptive isocurves. Using refinement and degree raising, two tools that are available in this system, different surfaces can be brought to a common function space and be continuously morphed or transformed from one to the other.
Line drawings is a neglected area of computer graphics.
