Computer Graphics

Code	14350
Year	3
Semester	S1
ECTS Credits	6
Workload	PL(30H)/T(30H)
Scientific area	Informatics
Entry requirements	Programming using an imperative language or an object-oriented language.
Mode of delivery	- Face-to-face.
Work placements	- N/A.
Learning outcomes	The general objectives are to provide students with: - programming and rapid prototyping skills of 2D and 3D graphics applications based on a graphic system (e.g., OpenGL) and a window system; - the basic skills in programming and geometric modeling of synthetic scenes on computer; - the essential skills in the generation of images of synthetic scenes in computer, which requires the understanding of the phenomena and interactions between light and the environment that lead to the formation of color; - mathematical skills behind fundamental methods, techniques and algorithms in computer graphics; - the core competencies in event-based programming. Concerning the specific objectives, students should be able at least to: - Develop and program an interactive graphical application in GLUT / OpenGL; Model and program a 3D scene through triangle meshes; - Schedule 3D scene lighting; - Program the application of textures to geometric models; - Develop and program a "ray caster".
Syllabus	Introduction to 2D/3D graphics. Light and color. Scanline rendering: graphics primitives, geometric transformations, and viewing transformations. Geometric computing: convex hull, k-nearest neighbors, triangle meshes, point clouds. Optics, illumination, and coloring: Blinn-Phong model; flat shading; Gouraud shading; Phong shading. Shader fundamentals and programming: vertex shader; fragment shader; scene graph. Textures: texture mapping; environment mapping; light mapping; bump mapping. Global illumination. Ray tracing: reflection and transmission; acceleration structures.
