Facts that you should know for Computer Graphics




  1. If you know what is BRDF stop, you know enough.
  2. SuperSampling means that it uses many samples to rasterize a pixel.
  3. When using Ray Tracing, usually you have a Shadow Cache
  4. Bump Mapping: Store Normals in a texture, basicaly false normals of a surface that is completly flat but with light it will appear that it is a bumping surface.
  5. Everything is divided in triangles once in the graphics card.
  6. The standard pipeline in grpahics card is divided in: Application, Geometry and Rasterization.
  7. If you learned openGl until 2015 and never checked for an update probably you do not know openGl anymore :c .
  8. Probably point 3 is gonna change in some months, so instead of Rasterization you will have Ray Tracing.
  9. A vertex shader runs three times per triangle.
  10. if 2 and 6 are true then a line ..
  11.  never use pure montecarlo for Raytracing.
  12. You should know what Russian Rouele is ....
  13.  Linear Algebra is mandatory
  14. TRS of course !
  15. You will have a pixelated shadow if you are using a low resolution Shadow Map technique.
  16. React Js is easier than OpenGl , who knows state now ?
  17. Texture Filtering two main techniques are Magnification and Minification.
  18. Quaternions are actually used in video games because of Computer Graphics.
  19. Unit quaternions help us describe a rotation with an axis and an angle.
  20. Z-Buffer Algorithm ....
  21. DDA Algorithm
  22. Why Maya, why Nuke, and why Unity.
  23. Should Gamma Correction exists ?
  24. That Mipmapping is being used and you just forgot.
  25. Billboards are the new Sprites baby.
  26. I also did Sprites in a game.
  27. Separating Area Theorem
  28. the 27 initials are the same as the SAT
  29. You probably like Direct3D
  30. You just forgot the Blending Equation.
  31. Here it is for you: c=a*cs + (1-a)cd
  32. So you might understand that alfa represents the ophacity.
  33. Smooth Dialetic Materials and Smooth Metal as smoth jazz exist...lol

Analysis of dark patterns in League of Legends and Star Wars:Battlefront II with the usage of Loot Boxes

The following analysis was done originally as an assignment for the Introduction to Game Research course at University of Gothenburg, first section fall 2019. The Darkness of a game design and its consequences revealed: Analysis of dark patterns in League of Legends and Star Wars:Battlefront II with the usage of Loot Boxes In some video games there are practices that are ethically questionable, which makes them go against what the player expects from the games. These practices of going against the player are called Dark Patters   (Staffan Björk) . As they are ethically questionable, I think it is good to identify (reveal) some of these patterns in games, which are currently very much played, and also reveal their current consequences. In specific, my analysis is going to consist in how League of Legends   (RIOT games, 2009) and Star Wars: Battlefront II   (Electronic Arts, 2017) have some characteristis that could mean that they are ussing the Grinding , M...

Kerstin's Fate developer diary

Image
Kertin's Fate developer diary Kertin's Fate Design: Kertin's Fate is a platform game directed and writed by Ivan Zamora, as part of Yao's Story games. The gameplay design for the game is based on the GNS model. Although GNS is based on role gaming, I decided to use the modes concept to direct design goals. The goal by ussing GNS is to "Focus on a gamism experience while narrating the game". Whit this goal, the game is not intended to advocate for simulationism, however things would change during testing. Moreover, for general gameplay I decided to stick with some common gameplay patterns. The game is designed by the following game play design patterns: Value of effort Luck Revoke Roles Character Levels Critical Failure Critical Success Items Gameplay Mastery  Time Limits On the other hand, to design character development I divided the experience according to the MDA framework, focusing mechanics as methods/actions. Mechanics: Jump/ double jump Sword attack Att...

Exploring LLMs with Ollama and Llama3

Image
I am going to use NodeJs and Windows 11 , however everything here should be the same for Linux or Mac , I just like my Windows machine for personal use. Steps to install the LLMs: 1) Install OLLAMA : this can be done by going to the ollama website https://ollama.com/ or using curl liek this: curl -fsSL https://ollama.com/install.sh | sh 2) Pull LLama3 with OLLAMA Ollama works something like a package manager but for LLMs , so to download LLAMA3 use the following command: ollama pull llama3 3) After doing so you can use Llama3 on your terminal ollma run llama3 "make a helloe world in C++" Steps to use it on usefull scenarios: 1) setup a nodejs/nmp project mkdir personal-llama cd personal-llama npm init -y we need to install ollama which is a client for the ollama server that we are running on the same machine sqlite3 because I want to have some personal data inside the ollama so it can execute responses based on me. chalk for nice l...
