13. CS559-Computer Graphics Copyright Stephen Chenney 2001 Grading 50% Midterm and Final 40% Programming Projects –Three projects, one for each “section” of class –You must attempt each project 10% Homework –About 1 every 2 weeks –Short, and you can drop one Everyone must write up their own homework, and write their own software, unless explicitly told otherwise

14. CS559-Computer Graphics Copyright Stephen Chenney 2001 Programming Issues FLTK will be the user interface toolkit –C++ class library –Provides windows, buttons, menus, etc OpenGL will be the 3D rendering toolkit –Provides an API for drawing objects specified in 3D Visual C++ 6.0 will be the programming environment To be graded, your project must compile under Visual C++ on the machines in room 1355

15. CS559-Computer Graphics Copyright Stephen Chenney 2001 Adding the Class To go on the waiting list, email schenney@cs.wisc.edu with your name, ID and major schenney@cs.wisc.edu Some people already on the list will be added this afternoon

16. CS559-Computer Graphics Copyright Stephen Chenney 2001 Programming Assignment 1 Do the FLTK demo off the class web page Will get you started with C++ and FLTK Do it NOW, don’t wait until the project comes up There will be another assignment in a week or so continuing your preparation for the first project Not graded.
