What is @luma.gl/constants?

@luma.gl/constants is a package that provides a set of constants used in WebGL and WebGL2 for rendering graphics. These constants are essential for setting up and managing various WebGL states and operations, such as defining buffer types, shader types, and texture parameters.

What are @luma.gl/constants's main functionalities?

Buffer Types

This feature provides constants for different types of buffers used in WebGL. ARRAY_BUFFER is used for vertex attributes, and ELEMENT_ARRAY_BUFFER is used for element indices.

const { ARRAY_BUFFER, ELEMENT_ARRAY_BUFFER } = require('@luma.gl/constants');
console.log(ARRAY_BUFFER); // 34962
console.log(ELEMENT_ARRAY_BUFFER); // 34963

Shader Types

This feature provides constants for different types of shaders. VERTEX_SHADER is used for vertex processing, and FRAGMENT_SHADER is used for fragment processing.

const { VERTEX_SHADER, FRAGMENT_SHADER } = require('@luma.gl/constants');
console.log(VERTEX_SHADER); // 35633
console.log(FRAGMENT_SHADER); // 35632

Texture Parameters

This feature provides constants for texture parameters. TEXTURE_2D is used for 2D textures, TEXTURE_WRAP_S and TEXTURE_WRAP_T are used for texture wrapping modes, and REPEAT is a wrapping mode that repeats the texture.

const { TEXTURE_2D, TEXTURE_WRAP_S, TEXTURE_WRAP_T, REPEAT } = require('@luma.gl/constants');
console.log(TEXTURE_2D); // 3553
console.log(TEXTURE_WRAP_S); // 10242
console.log(TEXTURE_WRAP_T); // 10243
console.log(REPEAT); // 10497

Other packages similar to @luma.gl/constants

    gl-matrix

    gl-matrix is a high-performance matrix and vector library for WebGL. While it does not provide WebGL constants, it offers utilities for matrix and vector operations, which are essential for 3D graphics rendering.

    twgl.js

    twgl.js is a library that simplifies the use of WebGL. It provides functions for creating shaders, buffers, and textures, and includes constants similar to those in @luma.gl/constants. However, twgl.js is more focused on simplifying WebGL programming rather than just providing constants.

    three

    Three.js is a popular 3D library that abstracts WebGL complexities and provides a higher-level API for creating 3D graphics. It includes many constants and utilities for 3D rendering, making it a more comprehensive solution compared to @luma.gl/constants.
