A tool that generates PVRTC, ETC1, ETC2, ASTC, DXT textures from png and jpg files.
npm install babylonjs-texture-generatorThis is a tool that generates PVRTC, ETC1, ETC2, ASTC, DXT textures from png and jpg files. It can run on node or as a gulp task.
It is meant to work with Babylon.js. The tool is a port of two .bat files.
In order to use the tool, you need to have installed:
* PVRTexToolCLI (download)
* ASTC Evaluation Codec (download)
Add ASTC Evaluation Codec* to your path, a process which depends on your OS. (documentation at page 5)
* Run npm run build in terminal
Import/require the exposed function generateTextures to your script. It accepts one argument as an object with the following attributes:
PVRTexToolCLI - string*: The absolute path to the PVRTexToolCLI tool.
inputDir - string*: The directory where the image files are located. It will be read recursively and all the images will be used in order to generate the new textures.
quality - string (optional), (options "low"/"high", default: "high")*: The quality of the exported textures.
exportFormats - string[] (optional) (options "PVRTC"/"ETC1"/"ETC2"/"ASTC"/"DXT", default: ["PVRTC", "ETC1", "ETC2", "ASTC", "DXT"])*: The format of the exported textures.
async - boolean (optional, default: false)*: Whether the task should run asynchronously.
Example usage:
``javascript
import generateTextures from "babylonjs-texture-generator";
// Alternatively
// const generateTextures = require("babylonjs-texture-generator");
createGpuTexture({
PVRTexToolCLI: "/Applications/Imagination/PowerVR_Graphics/PowerVR_Tools/PVRTexTool/CLI/OSX_x86/PVRTexToolCLI",
inputDir: "/src",
quality: "high",
async: false,
exportFormats: ["PVRTC", "ETC1", "ETC2", "ASTC", "DXT"]
});

Currently DXT files can not be exported on MacOS.
