【41】可视化平台—three.js应用开发小岛案例

This summary outlines the key components and setup of a 3D scene using Three.js and related libraries in a Vue component. The code demonstrates the initialization of the scene, camera, renderer, controls, sky texture, water geometry, lighting, and GLTF model loading, as well as the handling of window resizing and video textures.

The scene is set up with a camera positioned and configured for perspective projection. A WebGLRenderer is created with antialiasing and logarithmic depth buffer enabled, and the renderer's size is set to fill the window. A sky texture is loaded and applied to a large inverted sphere to create a skybox. Environmental HDR lighting is added by loading a texture and applying it to the scene's background and environment.

Interactivity is introduced with a video texture that plays when the user clicks the window. A water surface is created with properties like color and flow direction, and is added to the scene after being rotated to lie flat. A directional light source is also added to the scene.

Complex models are loaded using the GLTFLoader, with DRACOLoader for compression, and added to the scene. To ensure the scene appears correctly on different screen sizes, an event listener is attached to the window's resize event, adjusting the camera's aspect ratio and the renderer's size accordingly.

OrbitControls are instantiated to allow for interactive camera movement, with damping enabled for a realistic feel. The render loop is set up to continuously render the scene. Finally, the renderer's canvas is appended to a container in the DOM, and Vue's reactive data properties are used to manage the scene's components.
