samples: 17, // Samples (default: 17)
rings: 11, // Rings (default: 11)
})
shaderMaterial() Creates a THREE.ShaderMaterial for you with easier handling of uniforms, which are also automatically declared as setter/getters on the object.
import { extend } from "react-three-fiber"
import glsl from "babel-plugin-glsl/macro"
const ColorShiftMaterial = shaderMaterial(
{ time: 0, color: new THREE.Color(0.2, 0.0, 0.1) },
// vertex shader
glsl`
varying vec2 vUv;
void main() {
vUv = uv;
gl_Position = projectionMatrix * modelViewMatrix * vec4(position, 1.0);
}
`,
// fragment shader
glsl`
uniform float time;
uniform vec3 color;
varying vec2 vUv;
void main() {
gl_FragColor.rgba = vec4(0.5 + 0.3 * sin(vUv.yxx + time) + color, 1.0);
}
`
)
extend({ ColorShiftMaterial })
<mesh>
<colorShiftMaterial attach="material" color="hotpink" time={1} />
<Html/> Allows you to tie HTML content to any object of your scene. It will be projected to the objects whereabouts automatically.
<Html
prepend // Project content behind the canvas (default: false)
center // Adds a -50%/-50% css transform (default: false)
fullscreen // Aligns to the upper-left corner, fills the screen (default:false)
scaleFactor={10} // If set (default: undefined), children will be scaled by this factor, and also by distance to a PerspectiveCamera.
zIndexRange={[100, 0]} // Z-order range (default=[16777271, 0])
portal={domnodeRef} // Reference to target container (default=undefined)
{...groupProps} // All THREE.Group props are valid
{...divProps} // All HTMLDivElement props are valid
>
<h1>hello</h1>
<p>world</p>
</Html>
<Reflector/> Easily add reflection to any object
<Reflector>
<planeBufferGeometry args={[2, 5]} attach="geometry" />
</Reflector>
<Shadow/> A cheap canvas-texture-based circular gradient.
<Shadow
color="black" // Color (default:black)
colorStop={0} // First gradient-stop (default:0)
opacity={0.5} // Alpha (default:0.5)
fog={false} // Reacts to fog (default=false)
/>
<Stats/> Adds stats to document.body. It takes over the render-loop!
<Stats
showPanel={0} // Start-up panel (default=0)
className="stats" // Optional className to add to the stats container dom element
{...props} // All stats.js props are valid
/>
You can choose to mount Stats to a different DOM Element - for example, for custom styling:
const node = useRef(document.createElement('div'))
useEffect(() => {
node.current.id = 'test'
document.body.appendChild(node.current)
return () => document.body.removeChild(node.current)
}, [])
return <Stats parent={parent} />
meshBounds() A very fast, but often good-enough bounds-only raycast for meshes. You can use this if performance has precidence over pointer precision.
<mesh raycast={meshBounds} />
useCamera() A hook for the rare case when you are using non-default cameras for heads-up-displays or portals, and you need events/raytracing to function properly (raycasting uses the default camera otherwise).
<mesh raycast={useCamera(customCamera)} />
useHelper() A hook for a quick way to add helpers to existing nodes in the scene. It handles removal of the helper on unmount and auto-updates it by default.
const mesh = useRef()
useHelper(mesh, BoxHelper, 'cyan')
useAspect()This hook calculates aspect ratios (for now only what in css would be image-size: cover is supported). You can use it to make an image fill the screen. It is responsive and adapts to viewport resize. Just give the hook the image bounds in pixels. It returns an array: [width, height, 1].
const scale = useAspect(
"cover", // Aspect ratio: cover | ... more to come, PR's welcome ;)
1024, // Pixel-width
512, // Pixel-height
1 // Optional scaling factor
)
return (
<mesh scale={scale}>
<planeBufferGeometry />
<meshBasicMaterial map={imageTexture} />
useGLTFLoader()A convenience hook that uses useLoader, GLTFLoader and draco:
useGLTFLoader(
url,
true // use draco binaries in /draco-gltf/
)
useGLFTLoader(
url,
'/my-draco-binaries' // use draco binaries from a custom path
)
useTextureLoader()A convenience hook that uses useLoader and TextureLoader
const texture = useTextureLoader(url)
const [texture1, texture2] = useTextureLoader([texture1, texture2])
useCubeTextureLoader()A convenience hook that uses useLoader and CubeTextureLoader
const envMap = useCubeTextureLoader(
['px.png', 'nx.png', 'py.png', 'ny.png', 'pz.png', 'nz.png'],
{ path: 'cube/' }
)
draco() Adds the Draco extension to your GLTFLoader, to be used in conjuction with useLoader and GLTFLoader when more control is needed.
useLoader(
GLTFLoader,
url,
draco(
'/draco-gtltf/' // Path to the Draco binaries (default='/draco-gtltf/')
)
)
