GL Texture

WebGL texture wrapper.

Installation

$ npm install --save @vaalentin/gl-texture

Usage

import Texture from '@vaalentin/gl-texture';

const texture = new Texture(gl, gl.TEXTURE_2D);

const img = document.createElement('img');

img.onload = () => {
	texture.bind(1);
	texture.setData(img);
}

img.src = '';

program.bind();
program.setUniform('uTexture', texture.bind(1));

API

texture = new Texture(gl, type)

texture = new Texture(gl, type, width, height)

texture = new Texture(gl, type, data)

Create a new texture, if no data is provided, the texture is empty.

• gl is the WebGL context.
• type is the texture type. Default is gl.TEXTURE_2D.
• data can be an image, video or canvas.

texture.setData(data)

Set the texture data. The texture must be bound first.

texture.bind(1);
texture.setData(image);

texture.bind(unit)

Bind the texture to the given unit, and returns it. Default is 0. This allows to set a program uniform at the same time.

program.setUniform('uTextureA', textureA.bind(0));
program.setUniform('uTextureB', textureA.bind(1));

texture.dispose()

Delete instance. Calls gl.deleteTexture().
