UnverifiedThe physics effects in 3D scenes generated by current large models are usually achieved by generating call code for JavaScript physics libraries (such as Cannon.js, Rapier), rather than the model internally establishing an accurate physical world model.68% similarUnverifiedJST-2 offers an API for developers.64% similarVerifiedThree.js abstracts the underlying WebGL graphics API into a scene graph model, allowing developers to build 3D scenes without directly writing GLSL shader code.60% similarUnverifiedMatter.js is a 2D physics engine written in pure JavaScript that supports physical effects such as rigid body collisions, constraint relationships, and gravity simulation.59% similarUnverifiedThe large-model test of "writing code to generate 3D content" examines the model's ability to generate runnable HTML/JavaScript code (often with the help of WebGL libraries such as Three.js) and have 3D scenes rendered in real time by the browser.57% similar
