Centered UV Visual

Visualize centered UV (vUv-0.5) as colors.

Overview

• Follow the steps to complete the exercise.

Learning Objectives

• Practice coordinate-based coloring

Prerequisites

• uv-coordinates

Key Concepts

• vUv is normalized UV in [0,1].

vec2 uv = vUv;

How To Implement (Step-by-step)

• Start from vUv.

Self-check

• Does it compile without errors?
• Does the output match the goal?
• Are key values kept in [0,1]?

Common Mistakes

• If output is black, check your mask/factor isn’t always 0.
