| Summary |
|---|
| The content of this course aims to expand the student's knowledge acquired in the course Computer Graphics I on real-time image synthesis techniques using modern graphics APIs. Emphasis is placed on the description of individual parts of the standard rendering pipeline, but also advanced hybrid approaches combining rasterization with recursive ray tracing methods to achieve a realistic appearance of the resulting images are discussed. Theoretical knowledge gained during discussion of partial tasks serve as a basis for practical implementation of specific examples during exercises. Exercises closely correspond to the lectures and the implementation of the aforementioned topics in the C++ language environment is assumed. |
| Learning Outcomes of the Course Unit |
|---|
The aim of the course is to supplement and expand the topics that the student could be acquainted with in the course Computer Graphics I with a focus on real-time image synthesis using rasterization and hybrid approaches. Emphasis is placed on the practical use of the graphical API OpenGL and Vulkan in creating programs for displaying 3D scenes demonstrating the individual discussed topics.
The graduate of the course will able to:
- define affine and projective transformations,
- describe the basic parts of a rendering pipeline,
- orient in the structure of the OpenGL API,
- configure individual parameters of the graphical interface and create program code for it in GLSL language,
- create more complex display chains of advanced techniques (deferred rendering, shadow generation, global lighting simulation),
- systematically analyze and eliminate errors in graphical output,
- combine rasterization with recursive ray tracing techniques,
- create applications for displaying interactive 3D graphics. |

2. Creation of basic shaders in GLSL language, construction of MVP matrix, scene integration, application of simple shaders on selected objects.
3. Working with buffers (geometric and frame buffers).
4. Advanced shading, materials, working with many materials.
5. Advanced texturing techniques, texture mapping and their creation (PBR materials).
6. Advanced lighting models, ambient occlusion, etc.
7. Techniques of modification of surface normals, calculation of local coordinate system TBN (e.g. bump mapping, normal mapping, displacement mapping, parallax mapping).
8. Shadow generation using shadow mapping and stencil buffer.
9. Implementation of deferred shading and its use in conjunction with recursive ray tracing (focused on shadows, reflection, and refraction).
10. Use of libraries for hardware acceleration of recursive ray tracing methods (e.g. OptiX, Radeon Rays).
11. Creation and visualization of a selected particle system.
12. Integration of a physical model into a scene.
13. Examples of game engines.
14. Checking the assigned tasks.
The exercises solve specific tasks from the discussed area. The implementation language is C++. |
