Procedural Equirectangular Textures

Neon lights

This texture generates plasma-like neon ligts. It overlaps up to three neon colors. The generated texture is intended for color maps. Click on a snapshot to open it online.

Code template

Code template of parameters with their default values.

import * as PET from "pet/patterns/neon-lights.js";
:
model.material.map = PET.texture( );
PET.material( model.material );

Parameters

The parameters of the texture generator are:

• width – texture width in pixels, default 512
• height – texture height in pixels, default 256
• scale – pattern size [0,100], default 50
• mode – additive or subtractive blending, default additive
• colorA – first neon color, default 0xFF0000 (red)
• colorB – second neon color, default 0x00FF00 (green)
• colorC – third neon color, default 0x0000FF (blue)
• background – background color, default 0x000000 (black)

In additive mode:

• neon colors are added to the background color
• background color is supposed to be dark
• a neon color is turned off when it is black

In subtractive mode:

• neon colors are subtracted from the background color
• background color is supposed to be light
• a neon color is turned off when it is white

API

All texture modules share the same API.

• pattern( x, y, z, color, options ) – pattern implementation
• texture( {params} ) – generator for a texture with given parameters
• defaults – object with default parameters
• material( ... ) – material shader patcher
