triplanarTexture
A UV-less automatic texturing technique that projects a texture from three axes (X, Y, Z) and intelligently blends them based on the model's surface orientation, completely solving issues with UV stretching, seams, and manual unwrapping.
Core Advantages
Its core advantage is completely eliminating the need for traditional UVs. For procedural models, 3D scanned objects, or any complex geometry difficult to UV unwrap, it allows for the direct application of seamless textures, greatly simplifying and accelerating the art workflow.
Common Uses
Adding seamless, natural materials to procedurally generated terrains or planets.
Quickly previewing and applying final materials to complex sculptures or 3D scanned models that lack UVs.
Applying continuous textures to large surfaces like walls and floors in architectural visualization.
How to adjust
Fine-tune the effect by adjusting optional parameters: 1. Change `scale` to control texture tiling density (a larger value results in a smaller pattern). 2. Adjust `sharpness` to alter the sharpness of the transition between projection planes. 3. Add a dynamic value (e.g., time) to the `position` input to create animated scrolling texture effects.
Code Examples
1// Implicitly uses world position and normal for projection and blending
2material.colorNode = triplanarTexture( texture( myTexture ) );
