Multimedia Course goals This course offers an in-depth exploration of fundamental concepts in 2D and 3D computer graphics. It introduces 2D raster graphics techniques, including scan conversion, simple image processing, interaction techniques and user interface design. The bulk of the course is devoted to 3D modeling, geometric transformations, and 3D viewing and rendering. Dr. Osama Mokhtar0.8

Multimedia Course goals ✪ A sequence of assignments culminates in a simple geometric modeler and ray tracer. C++ and the graphics library OGL are used throughout the course, as is shader programming on the GPU, taught from the first lab onwards. The final project is typically a small group project spec'd and implemented by the group using shaders to create special effects. Dr. Osama Mokhtar0.9

Multimedia Course contents ✪ Graphics Algorithms, ✪ 2D and Introduction, ✪ Graphics Hardware ✪ Basic Raster 3D Transformations ✪ Synthesized Camera Models: ✪ Curve and surfer representation Dr. Osama Mokhtar0.10

Multimedia Course contents ✪ Lightening Models : ✪ Shading Techniques: ✪ Shadows: ✪ Texture Mapping: ✪ Transparency. Dr. Osama Mokhtar0.11

The textbook for this class is recommended, but not required Most lectures will correspond to chapters in the book An improved index has been linked on the site’s docs page

Multimedia Projects ✪ Brush – a 2d drawing program (intro to C++) ✪ Shapes – tessellating primitives ✪ Filter – image processing, including anti- aliasing ✪ Sceneview – 3d static scene viewer for OpenGL ✪ Intersect – parametric shapes, ray-shape intersections ✪ Ray – your own 3d rendering engine Dr. Osama Mokhtar0.16

Multimedia Projects ✪ Each project is preceded by a short “algo” assignment, which ensures that you understand the concepts behind the project before starting to code. Dr. Osama Mokhtar0.17

Multimedia Labs ✪ Lab 1: VBOs  a 2d drawing program (intro to C++) ✪ Lab 2: Shaders ✪ create and animate 3D shapes ✪ Lab 3: Debugging ✪ learn to fix errors and simulate lighting ✪ Lab 4: Filter ✪ 3d static scene viewer for OpenGL Dr. Osama Mokhtar0.18
