Is there an example of updating the camera initial position?

react-stl-viewer

React component for visualizing STLs using Three.js.

Install

npm install --save react-stl-viewer

or

yarn add react-stl-viewer

Usage

import React from 'react';
import ReactDOM from 'react-dom';
import {StlViewer} from "react-stl-viewer";

const url = "https://storage.googleapis.com/ucloud-v3/ccab50f18fb14c91ccca300a.stl"

const style = {
    top: 0,
    left: 0,
    width: '100vw',
    height: '100vh',
}

function App() {
    return (
        <StlViewer
            style={style}
            orbitControls
            shadows
            url={url}
        />
    );
}

ReactDOM.render(<App/>, document.getElementById('root'));

Props

Prop	Type	Required	Notes
`url`	`string`	`true`	url of the Stl file
`cameraProps`	`CameraProps`	`false`	camera properties, see below
`modelProps`	`ModelProps`	`false`	3d model properties, see below
`floorProps`	`FloorProps`	`false`	floor properties, see below
`shadows`	`boolean`	`false`	render shadows projected by the model on the ground
`showAxes`	`boolean`	`false`	show x y z axis
`orbitControls`	`boolean`	`false`	enable camera orbit controls
`extraHeaders`	`Record<string, string>`	`false`	custom headers for making the http query
`onFinishLoading`	`(ev: ModelDimensions) => any`	`false`	callback triggered when Stl is fully loaded
`onError`	`(err: Error) => any`	`false`	callback triggered when an error occurred while loading Stl
`canvasId`	`string`	`false`	id of the canvas element used for rendering the model

The component also accepts <div/> props

Interfaces

CameraProps

Prop	Type	Required	Notes
`ref`	`{current: CameraRef}`	`false`	reference of the camera for accessing it's properties
`initialPosition`	`CameraPosition`	`false`	set the position of the camera in geographic coordinates. The origin of coordinates is the object itself

CameraRef

Prop	Type	Required	Notes
`setCameraPosition`	`(position: CameraPosition) => any`	`true`	imperatively sets the camera position based on the provided geographic coordinates

setCameraPosition:

ModelProps

Prop	Type	Required	Notes
`ref`	`{current: ModelRef}`	`false`	reference of the 3d model for accessing it's properties
`scale`	`number`	`false`	scale of the 3d model, defaults to 1
`positionX`	`number`	`false`	x coordinate in the world of the 3d model
`positionY`	`number`	`false`	y coordinate in the world of the 3d model
`rotationX`	`number`	`false`	rotation in x axis of the model
`rotationY`	`number`	`false`	rotation in y axis of the model
`rotationY`	`number`	`false`	rotation in z axis of the model
`color`	`CSSProperties['color']`	`false`	color of the 3d model, defaults to "grey"
`geometryProps`	`(geometry: BufferGeometry) => BufferGeometry`	`false`	Perform some processing to the models geometry

FloorProps

Prop	Type	Required	Notes
`gridWidth`	`number`	`false`	if specified, a grid will be drawn in the floor with this width
`gridLength`	`number`	`false`	if specified, a grid will be drawn in the floor with this length

ModelDimensions

Prop	Type	Notes
`boundingRadius`	`number`	the radius of the bounding sphere of the 3d model before scaling
`width`	`number`	width of the 3d object
`height`	`number`	height of the 3d object
`length`	`number`	length of the 3d object

CameraPosition

Prop	Type	Required	Notes
`latitude`	`number`	`false`	camera's position latitude, it should be a number between `- Math.PI / 2` and `Math.PI / 2`, if the number exceeds the limits it will be clamped
`longitude`	`number`	`false`	camera's position longitude, it should be a number between `- Math.PI` and `Math.PI`, if the number exceeds the limits it will be clamped
`distance`	`number`	`false`	the distance factor between the object and the camera. This is a factor relative to the object size or the grid size if it's specified
