re please recommend d graphics library for mac robert g carpenter writes hi netters i m building a cad package and need a d graphics library that can handle some rudimentry tasks such as hidden line removal shading animation etc can you please offer some recommendations i ll also need contact info name address email if you can find it thanks please post your responses in case others have same need bob carpenter the following is extracted from sumex aim stanford edu it should also be on the mirrors i think there is source for some applications that may have some bearing on your project poke around the source directory i ve never used this package nor do i know anyone who did but the price is right hope this helps cheinan abstracts of files as of thu apr pst directory info mac source binhex d grafsys hqx date fri mar from christian steffen ove franz cfranz iiic ethz ch to questions mac archive umich edu subject d grafsys in incoming directory a d grafsys short description follows programmers d grafsys vers now available version is mainly a bugfix for think c users this version now runs with think c i promise the docs now contain a chapter for c programmers on how to use the grafsys if you have problems feel free to contact me the other change is that i removed the fastperftrig calls from the fpu version to make it run faster those of you who don t know what all this is about read on programmers d grafsys what it is didn t you always have this great game in mind where you needed some way of drawing three dimensional scenes didn t you always want to write this program that visualized the structure of three dimensional molecules and didn t the task of writing your d conversions routines keep you from actually doing it well if the answer to any of the above questions is yes but what has it to do with this package read on grafsys is a think pascal c library that provides you with simple routines for building saving loading as resources and manipulating independent rotating around arbitrary achses translating and scaling three dimensional objects objects not just simple single line drawings grafsys supports full d clipping animation and some primitive hidden line hidden surface drawing with simple commands from within your program grafsys also supports full eye control with both perspective and parallel projections if you can t understand a word don t worry this is just showing off for those who know about it the docs that come with it will try to explain what it all means later on grafsys provides a powerful interface to supply your own drawing routines with data so you can use grafsys to do the d transformations and your own routines to do the actual drawing note that grafsys also provides drawing routines so you don t have to worry about that if you don t want to grafsys comes in two versions one for the and or above processors the other version uses fixed point arithmetic and runs on any mac both versions are source compatibel grafsys comes with an extensive manual that teaches you the fundamentals of d graphics and how to use the package if demand is big enough i will convert the grafsys to an object class library however i feelt that the way it is implemented now makes it easier to use for a lot more people than the select oop guild grafsys is free for any non commercial usage read the documentation enclosed enjoy christian franz
