texture2cube v1.0.2

Texure2Cube

Generate a cube like image from three textures without canvas, which could allow a server side system to do this work.

Texture2Cube uses ndarray to load image data, then use this data to transform the textures.

usage

Install and import it as a module.

npm i texture2cube 

Here shows a basic example:

var CubeImage = require('texture2cube');

var cubeImage = new CubeImage({
    top: 'texture_top.png',
    left: 'texture_left.png',
    rignt: 'texture_right.png',
})

cubeImage.toPng('./cube.png');

API

Constructor

constructor accepts five inputs:

• left: left texture
• right: right texture
• top: top texture
• scale: (optional)scale the output image
• info: (optional)can pass some data and get by cubeImage.getPixels

Output

• cubeImage.toCanvas(element): append a canvas to element.
• cubeImage.toCanvas(): append a canvas to body
• cubeImage.toPng('result.png') output to a png file
• cubeImage.getPixels(callback(pixels, info)): pixels are the ndarray type of the result image data, info is the data from constructor.
