Pieroni, Goffredo G.2024-04-222024-04-22198718433947https://hdl.handle.net/10657/17030The CORE protocol provides a list of standard features for constructing a program in dealing with two-dimensional and three-dimensional object representations. The most important features of a such system are linear transformation, windowing, clipping, viewing transformation, projection, hidden-line elimination and hidden-surface removal. In this thesis, the implementation of the CORE system is based on Steven Harrington's book "Computer Graphics - A Programming Approach" by McGraw Hill. A list of basic algorithms is critically analyzed. Errors were discovered in some important algorithms as proposed by Harrington. A corrected version is presented and implemented. Finally a set of experiments for constructing 3D objects has been performed by using different output devices : Lexidata, Tektronix and Printronix. The principal one consists of displaying a 3D surface of a human heart obtained by a sequence of PET images.application/pdfenThis item is protected by copyright but is made available here under a claim of fair use (17 U.S.C.
