he computer Science Curricula 2023 (CS2023) was endorsed by their sponsoring organizations: the Association of Computing Machinery (acm), IEEE Computing Society (IEEE CS), and the Association for the Advancement of Artificial Intelligence (AAAI) in early 2024. The document was produced over the course of four years and was the collaborative work of approximately 100 volunteers from six continents. In keeping with current curricular design principles, the guidelines incorporate a competency model (what is learned) in addition to the traditional knowledge model (what is taught). This talk is geared to anyone interested in computer science graphics education who would like to learn more about the guidelines and the on-going computing curricular efforts. We will describe the organization of CS2023, the graphics and interactivetechniques Knowledge Area including its new Knowledge Unit, Society Ethics and the Profession.

The visual quality of raster images makes them attractive for applications such as business graphics and document illustration. Such applications are most fully served using interactive systems to describe curves, areas and text which can be rendered at high resolution for the final copy. However, to present such imagery in an interactive environment for moderate cost is difficult. techniques are presented that provide solutions to the problems of scan conversion, screen update, and hit testing for a class of interactive sytems called illustrators. The design rests on the use of software display file encoding techniques. These ideas have been used in the implementation of several illustration programs on a personal minicomputer. � acm.

G-SYNC technology matches formerly regular display refreshes to irregular frame updates, improving frame rates and interactive latency. In a previous study of gaming at the 30Hz frame rates common on consoles, players of Battlefield 4 were unable to discern when G-SYNC was in use, but scored higher with G-SYNC and were affected emotionally. We build on that study with the first examination of G-SYNC's effects at the 60Hz frame rate more common in PC gaming and on emerging consoles. Though G-SYNC's effects are less at 60Hz than they were at 30Hz, G-SYNC can still improve the performance of veteran players, particularly when games are challenging. G-SYNC's effects on emotion and experience were limited.

Geometric transformations are most commonly represented as square matrices in computergraphics. Following simple geometric arguments we derive a natural and geometrically meaningful definition of scalar multiples and a commutative addition of transformations based on the matrix representation, given that the matrices have no negative real eigenvalues. Together, these operations allow the linear combination of transformations. This provides the ability to create weighted combination of transformations, interpolate between transformations, and to construct or use arbitrary transformations in a structure similar to a basis of a vector space. These basic techniques are useful for synthesis and analysis of motions or animations. Animations through a set of key transformations are generated using standard techniques such as subdivision curves. For analysis and progressive compression a PCA can be applied to sequences of transformations. We describe an implementation of the techniques that enables an easy-to-use and transparent way of dealing with geometric transformations in graphics software. We compare and relate our approach to other techniques such as matrix decomposition and quaternion interpolation.
