CS602 Computer Graphics is a foundational core course in the computer science degree program at the Virtual University of Pakistan, engineered to provide students with rigorous mathematical grounding and software development skills in visual computing, synthetic image generation, and modern interactive graphics pipelines. Grounded in authoritative textbooks by Hearn and Baker, Foley, and Angel, the academic curriculum traces the full progression of computer graphics from foundational hardware architectures to advanced three-dimensional rendering algorithms. Students begin by investigating display technology, contrasting video display cathode-ray tubes (CRTs), raster-scan systems, random-scan vector displays, and frame buffer architectures. In the rasterization modules, scholars master scan-conversion algorithms for fundamental 2D output primitives, analyzing the Digital Differential Analyzer (DDA), Bresenham line algorithm, midpoint circle algorithm, and midpoint ellipse generation. The course explores area filling methodologies, comparing boundary-fill and flood-fill recursion with efficient scan-line polygon fill algorithms and edge table management. Linear algebra fundamentals are thoroughly integrated, enabling students to formulate 2D and 3D affine geometric transformations using homogeneous coordinate matrices for translation, rotation, scaling, reflection, and shearing. Scholars evaluate two-dimensional viewing pipelines, mastering window-to-viewport coordinate mapping and clipping algorithms including Cohen-Sutherland line clipping, Liang-Barsky parametric clipping, and Sutherland-Hodgman polygon clipping. In three-dimensional graphics, students examine perspective and parallel projections, viewing frustums, surface normal calculations, triangle rasterization, and back-face culling. Illumination and shading modules cover ambient, diffuse, and specular reflection via the Phong illumination model, contrasting flat shading, Gouraud intensity interpolation, and Phong normal interpolation. Practical lab coursework introduces students to the OpenGL graphics library, exploring state machine architecture, modelview and projection matrix stacks, lighting parameters, and texture mapping. Advanced topics examine parametric polynomial curves, Bernstein polynomials, de Casteljau Bezier evaluation, fractal geometry generation, and keyframe computer animation principles. Through solved past papers by Moaaz and Waqar Siddhu alongside interactive practice MCQs on VU SIGMA, CS602 equips learners for academic excellence and professional careers in game development, simulation engineering, and scientific visualization.
