Computer Geometry and Graphics
FSI-1PG-KAcad. year: 2017/2018
Computer geometry and Graphics introduces basic knowledge of projective geometry and computer graphics which is used in CAD systems and graphics modelers. The base of the subject is in connection of theoretical knowledge with the work in graphics modelers. Synthetic and analytic constritions of basic plane and spatial figures and methods of their mapping and software representation are the course substantiality.

Learning outcomes of the course unit
Students will obtain the wide overview about the computer graphics and also about the parts of geometry which support the technical display systems (solids projection, curves and surfaces of technical practice, lighting). The student will be able to work in graphic studio and use the fundamental functions of the software with new theoretical knowledge. This approach learn him how to work with other graphic systems in short time.
Prerequisites
Knowledge of mathematics in secondary school level, especially geometry and descriptive geometry (two-plane (Monge's) projection, axonometry).
For students who did not attend the descriptive geometry on secondary school there is a possibility to attend the course Selected Chapters from Descriptive Geometry.
For students who did not attend the descriptive geometry on secondary school there is a possibility to attend the course Selected Chapters from Descriptive Geometry.
Co-requisites
Not applicable.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes
Course/unit credit is conditional on the following: Active attendance at seminars and
three seminar works per 10 points. Each work contains two parts: graph (max 5 points)
and Rhinoceros model (max 5 points). Course credit: minimal one point in each part of
each work and 15 total point.
Examination: written part consists of three drawing (20 + 20 points) and one calculation
(20 bodů). The last 10 points is possible to obtain in oral part of examination.
Grading scheme:
excellent (100 - 90 points),
very good(89 - 80 points),
good (79 - 70 points),
satisfactory (69 - 60 points),
sufficient(59 - 50 points),
failed (49 - 0 points).

Aims
The gist of the subject is to introduce students basic knowledge of projective geometry and computer graphics which is used in CAD systems and graphics modelers. Students will learn the classic geometry and computer graphics as well. The base of the subject is in connection of theoretical knowledge with the work in graphics modelers. Students will work with graphics software Rhinoceros.
Specification of controlled education, way of implementation and compensation for absences
If a student does not satisfy the given conditions, the teacher can set an alternative condition. The seminars are compulsory, lectures are optionally but very recommend.
