Arvutigraafika seminar 2023/24 kevad

Some arbitrary possible topics

1. Color blending – What happens when there are transparent objects in your scene?
2. Lighting models – What are the common models? Where and when are they used?
3. Texturing – How can one sample from a texture? What kinds of artefacts may appear?
4. Curves – Why are they important in CG? What about curved surfaces?
5. Global illumination – Pick one or compare different methods: Radiosity, path tracing, photon mapping.
6. Realtime realistic rendering – Provide an overview of the common methods or pick some effect (light, wetness, fog, fur / hair, skin) and find out how it's rendered realistically in real time.
7. Non-realistic rendering – Where is it used and how is it achieved? Realtime vs prerendered?
8. Tessellation – How can this be done in OpenGL 4?
9. Post-processing effects – What effects are there? When and how are they used?
10. Procedural generation (PCG wiki) – Where and how is it used? How to apply procedural textures to procedurally generated meshes?
11. Physically-Based Shading – What is it? Why is it important to understand physical properties of materials for shading? What games / game engines use it?
12. Rendering in VR – What extra considerations are in VR? How do different technologies overcome them?
13. Vulkan – What can be done with it? Why is it useful? How to Vulkan?
14. Subsurface scattering – What is it? How it is implemented? What does it solve?
15. Reflections and caustics – What are the modern techniques, which do those?
16. GLSL vs HLSL – What are the differences? How are both used?
17. Case study – Find out in detail how graphics are done in one game or movie:
    
    • The Code Corsair blog has several case study articles.
    • Dreams engine by Alex Evans (slides, second video)
    • Claybook - a game using exlusively SDFs.
    • GTA V - Graphics Study.
    • ...
18. Motion capture – What are the difficulties today? Best budget setup for it?
19. Modern GPU architecture – How are GPU-s built today? What are they optimized for? E.g. Vega, Kepler, Pascal.
20. Graphics on consoles / smartphones – What limitations are there in consoles or embedded systems vs the PC? How to overcome them compared to the PC approach?
21. Tileable Textures – What methods are there for creating those? Manual vs procedural?
22. Ray Tracing with RTX – What can be done with Nvidia's RTX cards?
23. Occlusion Culling – How is this achieved? What data structures are used?
24. Volumetric Rendering – How to simulate volumetric light transport? Fog, fire rendering?
25. Facial Animations – How is it achieved? What are the modern, cheapest, professional solutions?
