Range (Slider)

In the previous lesson, we explored why lil-gui is a powerful GUI library for Three.js . Now, we’ll dive into one of the most commonly used controls in lil-gui —the Range (Slider). Sliders are essential for dynamically adjusting values like: Object transformations (size, position, rotation). Material properties (opacity, roughness, metalness). Light intensity (brightness, distance, color blending). By the end of this lesson, you’ll know how to add sliders to your GUI panel and make real-time changes to your 3D objects.

The rest of this lesson is waiting.
