<shader-art> TexturePlugin

Installation

Install via NPM:

npm i shader-art @shader-art/plugin-texture

Or use directly via skypack:

import { TexturePlugin } from 'https://cdn.skypack.dev/@shader-art/plugin-texture';

Usage

Texture support can be added via a TexturePlugin.

You can load the texture plugin by importing the TexturePlugin and adding it to the ShaderArt.register call like this:

ShaderArt.register([() => new TexturePlugin()]);

Adding textures to your shader-art

Inside the shader art component, add an img tag like this;

<img
  src="https://placekitten.com/512/512"
  name="cat"
  wrap-s="mirrored-repeat"
  wrap-t="clamp-to-edge"
  min-filter="nearest"
  mag-filter="nearest"
  hidden
/>

Inside your glsl shader code (which is placed inside a <script type="vert|frag"> tag), you can access the texture via a uniform variable:

uniform sampler2D cat;

Attributes

• src url of the texture.
• name name of the uniform variable
• wrap-s horizontal texture wrapping (mirrored-repeat|repeat(default)|clamp-to-edge)
• wrap-t vertical texture wrapping (mirrored-repeat|repeat(default)|clamp-to-edge)
• min-filter texture minification filter (linear, nearest(default), nearest-mipmap-nearest, linear-mipmap-nearest, linear-mipmap-linear, nearest-mipmap-linear)
• mag-filter texture magnification filter (linear|nearest(default))
