Graphic systems and applications [ LINGI2325 ]

The programming assignment for this course (which is rather elaborate) requires good programming skills and the use of the UNIX operating system.

• Hardware for graphics systems.
• Fundamental concepts of computer graphics software.
• Data structures used in graphics applications.
• Study of specialized algorithms: line drawing, polygon filling, transformations, clipping, perspective projection, visible-surface determination, ray tracing, radiosity.
• Study and use of standard software packages for graphics applications.
• Modelling surfaces and threedimensional objects.

• Master the fundamental concepts in the field of Computer Graphics, in particular the high-level notions which allow to minimize the impact of hardware characteristics and facilitate the construction of well-structured programs.
• Know the principles underlying the main algorithms for object visualisation: line drawing, raster conversion, clipping, transformations, projections (perspective), shading, hidden-surface elimination.
• Understand the structure of software packages for graphics applications. - Learn to construct software for graphics applications.
• Know the most important techniques for modelling threedimensional objects.

• Lectures
• Two programming assignments allow the students to become acquainted with the implementation details of some of the algorithms presented in the course (3-D transformations and perspective, hidden surface elimination, ray tracing, ...)

• Fundamental algorithms for the visualisation of 2-D primitives on raster hardware: lines, circles, polygons, clipping, filling.
• Geometrical transformations (2-D and 3-D), projections.
• Representations of curves and surfaces: polygonal meshes, parametric cubic curves, parametric bicubic surfaces, fractal models, grammar-based models.
• Solid modelling using boolean operations, sweeping, spatial partitioning.
• Human perception of light and color.
• Visible-surface determination algorithms: z-buffer, scan-line algorithms, ray casting, priority lists, image subdivision.
• Shading models and shadow casting, ray tracing, transparency, radiosity, global illumination.
