Standard View

Usage

Install

$ npm install @standard/view

Place Views into your React App. For example:

import { View3D, Box } from '@standard/view';
.
.
.
<View3D>
  <Box position={[1, 0, 0]} color="green" />
  <Box position={[-1, 0, 0]} color="red" />
</View3D>

For details about valid properties, look at the interfaces named *Props, where * is the component name, in src/primitves/ and src/groups/.

Mesh

All Standard View primitives are composed within Mesh, with the exception of Line, BoundingBox, Text, and Group. Therefore, properties of Mesh are common to nearly alll components. Here is a list of explicitly managed Mesh properties in Standard View:

Mesh Properties

• position: Array<number>
• scale: Array<number>
• rotation: Array<number>
• quaternion: Array<number>

Material Properties

• color: string
• hoverColor: string
• opacity: number
• texturePath: string
• textureURL: string
• material: THREE.Material

Geometry Properties

• wireframe: boolean
• side: number
• geometry: THREE.Geometry

Animation Properties

• animation: Function
• state: Object

Event Properties

• onClick: Function
• onDoubleClick: Function
• onWheel: Function
• onPointerUp: Function
• onPointerDown: Function
• onPointerOver: Function
• onPointerOut: Function
• onPointerMove: Function

Mesh can also support animations via the animation property. A function with one argument that may be destructured to include state, setState, mesh, and any Canvas properties desired for the animation. All primitives and shapes may have animation. These animations are reactive, so they incur many render calls, but also maintain react-three-renderer's native raycasting for the event property functions.

Mesh also exposes react-three-fiber's the event property functions but with a constrained argument set, similar to animation. All event property functions take one arguement that may be destructured to include mesh, state, setState, and any Canvas prop. The benefit of this design, just like animations, is that a reference to mesh is automatically provided. Moreover, react-three-fiber's Canvas state properties are exposed. This allows event functions to reach right into the react-three-fiber/three.js's scene, camera, gl, etc. Hence all shapes that are Meshs may have these event property functions.

Of course, Mesh can accept properties handled by react-three-fiber/three.js as well. After explicitly managing these properties, remaining properties are passed to react-three-fiber's mesh. (Mesh is a wrapper of react-three-fiber's mesh, which is a wrapper of THREE.Mesh.)

View3D

Here is a list of explicitly managed View3D properties in Standard View:

WebGLRenderer Properties

• background: string

Camera Control Properties

• trackballControls: boolean
• orbitControls: boolean
• mapControls: boolean

Of course, View3D can accept Canvas properties handled by react-three-fiber as well. The Standard View properties are handled and stripped away before passing the properties to Canvas. (View3D is a wrapper of react-three-fiber's Canvas.)

Text

Text in Standard View is composed within a Mesh. So Text may accept all the same properties as a Mesh. Text also should have a text property with the desired string to be displayed and also a font or fontName. fonts are typeface.json fonts and must be a THREE.Font. The default three.js fonts are also included in Standard View, so simply passing fontName with one of those fonts will work.

Fonts

• helvetiker
• helvetikerBold
• optimer
• optimerBold
• gentilis
• gentilisBold

In general Text will be much more computation expensive to render compared to Label which is just a Plane with a texture of the desired text.
