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
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
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
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...
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...
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...
What We're Learning In previous articles, we created patterns using explicit boundaries: "Is this pixel inside the square?" But there is a more powerful way to define shapes in computer graphics: "How far is this pixel from the edge?" This is the wor...
What We're Learning In the real world, colors are rarely static. The sky shifts from deep azure to pale cyan; a metal pipe has a bright highlight that fades into shadow; a sunset paints the clouds in bands of orange, pink, and purple. To replicate th...
What We're Learning In the last article, we learned how to give a surface a solid color or a smooth gradient. But the real world is full of intricate details - bricks, tiles, fabrics, and complex designs. How do we create these without relying on pre...
