How to use

Loading XML file

最基本的用法是通过Krpano组件的xml参数直接加载krpano xml文件。 Krpano 组件将忠实地根据 xml 配置进行渲染。

krpano.xml

<krpano onstart="loadscene(scene1);">
    <scene name="scene1">
        <image>
            <cube url="https://some.jpg_%s" />
        </image>
        <hotspot
            name="image_hotspot"
            type="image"
            url="https://0xllllh.github.io/krpano-examples/images/hotspot.png"
            ath="0"
            atv="0"
        />
    </scene>
    <view hlookat="0" vlookat="0" fovtype="VFOV" fov="90" fovmin="30" fovmax="150" />
</krpano>

App.css

.App {
    width: 600px;
    height: 400px;
}

App.tsx

ReactDOM.render(<Krpano className="App" xml="/krpano.xml" />, document.getElementById('app'));

Scene display and switching

为了简化实现和使用,krpano的图片标签的实现已经合并到场景组件。 场景的图片可以通过Scene组件的images属性指定

要添加场景,需要使用Scene组件。 每一个代表一个场景,可以通过 Krpano 组件的 currentScene 属性指定活动场景。

ReactDOM.render(
<Krpano currentScene="scene0">
    <Scene
        name="scene0"
        images={[{
            type: 'cube',
            url: 'https://qhyxpicoss.kujiale.com/r/2017/09/01/L3D221IS3QKUQUQBOGAPEK3P3XU888_7500x1250.jpg_%s',
        }]}
    />
    <Scene
        name="scene1"
        images={[{
            type: 'cube',
            url: 'https://qhyxpicoss.kujiale.com/r/2017/09/01/L3D221IS3QKUQUQBOGAPEK3P3XU888_7500x1250.jpg_%s',
        }]}
    />
    <View fov={90} fovmin={80} fovmax={120} />
</Krpano>,
document.getElementById('app'));

Hotspots

目前仅支持图像热点

使用热点组件可以轻松渲染热点。 支持一堆回调设置

const App = () => {
    const [currentScene, setCurrentScene] = React.useState('scene0');
    // Datas
    const scenes = [{
        name: 'scene0',
        previewUrl: '/preview.jpg',
        hotspots: [{
            name: 'hot',
            type: 'image',
            url: 'hotspot.png',
            ath: 0,
            atv: 20,
            onClick: () => setCurrentScene('scene1')
        }]
    },
        name: 'scene1',
        previewUrl: '/preview.jpg',
        hotspots: []
    }]

    return (
        <Krpano currentScene={currentScene}>
            <View fov={90} fovmin={80} fovmax={120} />
            {scenes.map(sc => (
                <Scene name={sc.name} previewUrl={sc.previewUrl}>
                    {sc.hotspots.map(pt => <Hotspot {...pt} />)}
                </Scene>
            ))}
        </Krpano>
    )
}

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

Access unsuported features

由于这个项目刚刚开始开发,很多组件和功能还没有完成。 如果有需要优先支持的功能,可以在Github上提issue。 如果需要,获取后可以使用KrpanoActionProxy自行调用krpano函数。

各种回调函数都会获取KrpanoActionProxy实例作为参数,封装的方法可以用来控制krpano。 您还可以使用 renderer.KrpanoRenderer 获取 krpano 的本机实例。

const App = () => {
    const [currentScene, setCurrentScene] = React.useState('scene0');
    const onHotspotClick = React.useCallback((renderer: KrpanoActionProxy) => {
        console.log(renderer.get('view.fov'));
        setCurrentScene('scene1');
    }, []);

    return (
        <Krpano
            className="App"
            currentScene={currentScene}
            onReady={renderer => {
                console.log('Ready message from App', renderer.krpanoRenderer);
            }}
        >
            <View fov={90} fovmin={80} fovmax={120} />
            <Scene name="scene0" previewUrl="/preview.jpg">
                <Hotspot
                    name="hot"
                    type="image"
                    url="https://0xllllh.github.io/krpano-examples/images/hotspot.png"
                    ath={0}
                    atv={20}
                    onClick={onHotspotClick}
                />
            </Scene>
            <Scene name="scene1" previewUrl="/preview.jpg" />
        </Krpano>
    );
};

另外,style、action等标签可以写成xml,然后通过Krpano组件的xml属性导入。

pano.xml

<krpano>
    <style name="hotspot_style" url="hotspot.png" scale="0.5" edge="top" distorted="true" onover="tween(scale,0.55);" onout="tween(scale,0.5);" />
    ...
</krpano>

App.tsx

const App = () => (
    <Krpano
        className="App"
        xml="/pano.xml"
        currentScene="scene0"
    >
        <Scene name="scene0" previewUrl="/preview.jpg">
            <Hotspot
                name="hot"
                type="image"
                style="hotspot_style"
                ath={0}
                atv={20}
            />
        </Scene>
    </Krpano>
);

❗️ Restrictions

  • Only one krpano panorama is displayed on a page at a time. If you need to display multiple panoramas at the same time, a lighter solution will be more appropriate.
  • React components only implement part of their functions for the time being.

???? How to use

Loading XML file

The most basic usage is to directly load the krpano xml file through Krpano the xml parameters of the component . The Krpano component will faithfully render according to the xml configuration.

krpano.xml

<krpano onstart="loadscene(scene1);">
    <scene name="scene1">
        <image>
            <cube url="https://some.jpg_%s" />
        </image>
        <hotspot
            name="image_hotspot"
            type="image"
            url="https://0xllllh.github.io/krpano-examples/images/hotspot.png"
            ath="0"
            atv="0"
        />
    </scene>
    <view hlookat="0" vlookat="0" fovtype="VFOV" fov="90" fovmin="30" fovmax="150" />
</krpano>

App.css

.App {
    width: 600px;
    height: 400px;
}

App.tsx

ReactDOM.render(<Krpano className="App" xml="/krpano.xml" />, document.getElementById('app'));

Scene display and switching

In order to simplify the implementation and use, the implementation of krpano's image tag has been merged into the Scene component. The images of the scene can be specified through the images props of Scene component

To add a scene, you need to use the Scene component. Each one represents a scene, and active scene can be specified through the currentScene prop of Krpano component.

ReactDOM.render(
<Krpano currentScene="scene0">
    <Scene
        name="scene0"
        images={[{
            type: 'cube',
            url: 'https://qhyxpicoss.kujiale.com/r/2017/09/01/L3D221IS3QKUQUQBOGAPEK3P3XU888_7500x1250.jpg_%s',
        }]}
    />
    <Scene
        name="scene1"
        images={[{
            type: 'cube',
            url: 'https://qhyxpicoss.kujiale.com/r/2017/09/01/L3D221IS3QKUQUQBOGAPEK3P3XU888_7500x1250.jpg_%s',
        }]}
    />
    <View fov={90} fovmin={80} fovmax={120} />
</Krpano>,
document.getElementById('app'));

Hotspots

Currently support only image hotspots

Hotspots can be easily rendered using Hotspot component. It support a bunch of callback settings

const App = () => {
    const [currentScene, setCurrentScene] = React.useState('scene0');
    // Datas
    const scenes = [{
        name: 'scene0',
        previewUrl: '/preview.jpg',
        hotspots: [{
            name: 'hot',
            type: 'image',
            url: 'hotspot.png',
            ath: 0,
            atv: 20,
            onClick: () => setCurrentScene('scene1')
        }]
    },
        name: 'scene1',
        previewUrl: '/preview.jpg',
        hotspots: []
    }]

    return (
        <Krpano currentScene={currentScene}>
            <View fov={90} fovmin={80} fovmax={120} />
            {scenes.map(sc => (
                <Scene name={sc.name} previewUrl={sc.previewUrl}>
                    {sc.hotspots.map(pt => <Hotspot {...pt} />)}
                </Scene>
            ))}
        </Krpano>
    )
}

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

Access unsuported features

Since this project has just started development, many components and functions are not yet completed. If there is a function that needs priority support, you can raise an issue on Github. If you want, you can use the KrpanoActionProxy to call the krpano functions by yourself after obtaining it.

Various callback functions will get the KrpanoActionProxy instance as a parameter, and the encapsulated method can be used to control krpano. You can also use renderer.KrpanoRenderer to get a native instance of krpano.

const App = () => {
    const [currentScene, setCurrentScene] = React.useState('scene0');
    const onHotspotClick = React.useCallback((renderer: KrpanoActionProxy) => {
        console.log(renderer.get('view.fov'));
        setCurrentScene('scene1');
    }, []);

    return (
        <Krpano
            className="App"
            currentScene={currentScene}
            onReady={renderer => {
                console.log('Ready message from App', renderer.krpanoRenderer);
            }}
        >
            <View fov={90} fovmin={80} fovmax={120} />
            <Scene name="scene0" previewUrl="/preview.jpg">
                <Hotspot
                    name="hot"
                    type="image"
                    url="https://0xllllh.github.io/krpano-examples/images/hotspot.png"
                    ath={0}
                    atv={20}
                    onClick={onHotspotClick}
                />
            </Scene>
            <Scene name="scene1" previewUrl="/preview.jpg" />
        </Krpano>
    );
};

In addition, tags such as style and action can be written in xml, then imported through xml prop of Krpano component.

pano.xml

<krpano>
    <style name="hotspot_style" url="hotspot.png" scale="0.5" edge="top" distorted="true" onover="tween(scale,0.55);" onout="tween(scale,0.5);" />
    ...
</krpano>

App.tsx

const App = () => (
    <Krpano
        className="App"
        xml="/pano.xml"
        currentScene="scene0"
    >
        <Scene name="scene0" previewUrl="/preview.jpg">
            <Hotspot
                name="hot"
                type="image"
                style="hotspot_style"
                ath={0}
                atv={20}
            />
        </Scene>
    </Krpano>
);
