GL-Matrix Mat4 Snippets
A Visual Studio Code extension providing code snippets for the gl-matrix library, specifically for the mat4 module. This extension is designed to speed up your development by offering ready-to-use snippets for common matrix operations.
Features
- Snippets for creating, manipulating, and transforming 4x4 matrices (
mat4) using the gl-matrix library.
- Supports JavaScript and TypeScript.
Usage
- Install the extension.
- Open a JavaScript or TypeScript file.
- Type a snippet prefix (e.g.,
mgl.mat4.create) and press Tab to insert the snippet.
