Prerequisites: basic knowledge of 2D and 3D graphics editing software.

Student workload balance:
- participation in laboratory classes (45 hours),
- participation in consultations (15 hours),
- individual student work at home (15 hours),

Quantitative indicators:
- student workload related to classes requiring direct participation of the instructor – 2.4 ECTS;

Rules for the use of Artificial Intelligence (AI):
During the course, the use of AI systems is allowed in the following areas:
1. Machine translation of source texts from foreign languages.
2. Searching for and organizing scientific sources.
3. Creating simulations and models of physical phenomena discussed during the lectures.

In the event of violations of the above rules, the student may be held accountable under separate disciplinary regulations.
