THIS LIBRARY DOES NOT DEPEND ON ANGULAR SO YOU CAN USE IN ANY PROJECT, Astro, React, Svelte, Vue, Next.js, etc. It offers a set of classes and utilities that simplify the creation and management of 3D scenes, renderers, cameras, controls, lights, objects, and animations. This library is designed to help developers quickly set up interactive 3D graphics without dealing with the boilerplate code typically associated with Three.js.

Installation

Section titled “Installation”Terminal window

Roadmap

Section titled “Roadmap”[ ] multiple renderers need to be able to accurately choose the correct object from the mouse[ ] examples with the effect composers[ ] any unifed and comphesive progress loader for all features in a threejs prop

$3

Section titled “Caveats”must set in tsconfig.json compilerOptions

also when you know a property exists on an object you must use @ts-ignore and debug the property to make sure until we can have more advanced typescript types, for our classes we provide getters for different types of the same property but for threejs objects thats harder if not impossible to dosometimes it seems there is a resize needed in order to see the threejs scene. you need to set a delay now before calling WMLThreeProps.init because there seems to be an issue with Angular v19 where the height of the element will be 0 before initial navigation of an element. It might be we have to listen for the resize on the element itselfensure you are using the exact version that this package is using or you might get severe type errors, these can be ignored as fundamental changes in three.js features truly require you to change the version but if you can get past types that will be great
