4.3 - Texture Wrapping Modes
What We're Learning You've learned how to sample textures, and you've learned how to filter them to keep them sharp or smooth. Now we encounter a new problem: what happens when a mesh is bigger than i

4.2 - Texture Filtering and Mipmapping
What We're Learning You've learned how to sample textures in shaders using UV coordinates. Now comes a critical question: how exactly does the GPU calculate the color between pixels? When you render a
4.1 - Texture Sampling Basics
What We're Learning Up until now, we've been generating colors procedurally - calculating them with math equations directly in our shaders. But most real-world 3D graphics rely on textures: images tha
3.8 - Advanced Color Techniques
What We're Learning Color is one of the most powerful tools in your graphics arsenal. So far, we've worked with basic color operations - sampling textures, mixing colors, and applying simple lighting. But there's a whole world of advanced color manip...
3.7 - Fragment Discard and Transparency
What We're Learning So far in this series, every fragment we've processed has been drawn to the screen. We've colored them, textured them, and lit them - but we've always drawn them. What if you don't want to draw certain fragments at all? What if yo...
3.6 - Procedural Noise
What We're Learning So far in this series, we've worked with mathematical functions like sine waves, smooth gradients, and geometric patterns. These are powerful, but they all share a common limitation: they are too perfect. Nature isn't perfectly re...
