Course detail

Computer Graphics

FSI-2PGAcad. year: 2021/2022

The course familiarises students with basic principles of geometric shape computer modelling and basic algorithm of computer graphics. Acquired knowledge is a precondition for successful work with CAD systems.
Lecture summary:
2-D modelling: explicit, parametric and polar curves, Ferguson, Beziere and Coons curves, basic plane transforms and their composition, modelling of rolling motion.
3-D modelling: parallel and perpendicular projection, linear perspective. Explicit, parametric and polar surfaces. Beziere and Coons surfaces and their connection. Surfaces defined by border. Space figure realistic representation, hide algorithm, constant shading. edge, surface
and volume modelling, curves, surfaces and solids operations, sweep modelling.

Learning outcomes of the course unit

Students will apply the knowledge acquired in mathmatics and descriptive geometry. This knowledge will be extended by understanding of technical curves and surfaces, students will gain skills necessary for the work with a professional graphic system (DESIGN CAD 3D). They will be made familiar with algorithm building and with Borland DELPHI environment, as well as programming of basic graphics systems.

Prerequisites

Students are expected to be familiar with basic terms of 3D geometry, basic problems of 3D geometry,
hyve basic knowledge of projection methods (Monge and orthographic projection) and a grasp of language Pascal and Borland Delphi environment.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through exercises which are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Requirements of credit obtainning: graphic program constructed in Borland DELPHI
environment, machine part graphic model constructed in DESIGN CAD.
