Threat Actor Exposes Playbook for Exploiting npm to Build Blockchain-Powered Botnets
A threat actor's playbook for exploiting the npm ecosystem was exposed on the dark web, detailing how to build a blockchain-powered botnet.
@luma.gl/webgl
Advanced tools
@luma.gl/webgl is a WebGL framework that provides a set of tools and utilities for working with WebGL. It is designed to simplify the process of creating high-performance 3D graphics applications in the browser. The package offers a range of features including context creation, shader management, buffer handling, and more.
Context Creation
This feature allows you to create a WebGL context, which is the starting point for any WebGL application. The code sample demonstrates how to create a WebGL context using a canvas element.
const {createGLContext} = require('@luma.gl/webgl');
const canvas = document.createElement('canvas');
const gl = createGLContext({canvas});
Shader Management
This feature provides utilities for managing shaders, which are essential for rendering graphics in WebGL. The code sample shows how to create vertex and fragment shaders using the @luma.gl/webgl package.
const {Shader} = require('@luma.gl/webgl');
const vertexShaderSource = `
attribute vec4 position;
void main() {
gl_Position = position;
}
`;
const fragmentShaderSource = `
void main() {
gl_FragColor = vec4(1, 0, 0, 1);
}
`;
const vertexShader = new Shader(gl, {source: vertexShaderSource, shaderType: gl.VERTEX_SHADER});
const fragmentShader = new Shader(gl, {source: fragmentShaderSource, shaderType: gl.FRAGMENT_SHADER});
Buffer Handling
This feature allows you to create and manage buffers, which are used to store vertex data. The code sample demonstrates how to create a buffer and upload vertex positions to it.
const {Buffer} = require('@luma.gl/webgl');
const positions = new Float32Array([
-1, -1,
1, -1,
-1, 1,
1, 1
]);
const positionBuffer = new Buffer(gl, {data: positions});
Three.js is a popular JavaScript library for creating 3D graphics in the browser. It provides a higher-level API compared to @luma.gl/webgl, making it easier to create complex 3D scenes with less code. However, it may offer less control over low-level WebGL operations.
Babylon.js is another powerful 3D engine for the web. It offers a comprehensive set of features for creating 3D games and applications, including physics, animations, and more. Like Three.js, it provides a higher-level API compared to @luma.gl/webgl.
PixiJS is a 2D rendering engine that can also handle some 3D graphics. It is designed for high-performance rendering and is often used for creating interactive graphics and games. While it focuses more on 2D, it can be a good alternative for simpler 3D tasks.
This module contains the WebGL Device adapter for luma.gl.
It also exports a set of JavaScript classes for the WebGL2 API. These represent the legacy luma.gl v8 API.
FAQs
