稀土。BufferGeometry.computeBoundingSphere():计算的半径为 NaN。“position”属性可能具有 NaN 值
REE.BufferGeometry.computeBoundingSphere(): Computed radius is NaN. The "position" attribute is likely to have NaN values
问:
我正在使用 Reactjs 和 React Three Fiber 为 3d 组件创建一个投资组合,它是一个单页应用程序,展示了不同的部分,并包含 3 个 3D 组件。
虽然 3 个组件中有 2 个显示得很好,但下面的一个组件出现以下错误:
“三。BufferGeometry.computeBoundingSphere():计算的半径为 NaN。“position”属性可能具有 NaN 值。
现在是 2 天,我正在尝试解决这个问题,但不幸的是,我正在努力寻找解决方案。
我的组件代码:
import React, { Suspense, useEffect, useState } from "react";
import { Canvas } from "@react-three/fiber";
import { OrbitControls, Preload, useGLTF } from "@react-three/drei";
import CanvasLoader from "../Loader";
const Computers = ({ isMobile }) => {
const computer = useGLTF("./desktop_pc/scene.gltf");
return (
<>
<mesh>
<hemisphereLight intensity={0.15} groundColor="black" />
<pointLight intensity={1} />
<spotLight
position={[-20, 50, 10]}
angle={0.12}
penumbra={1}
intensity={1}
castShadow
shadow-mapSize={1024}
/>
<primitive
object={computer.scene}
scale={isMobile ? 0.7 : 0.75}
position={isMobile ? [0, -3, -2.2] : [0, -3.25, -1.5]}
rotation={[-0.01, -0.2, -0.1]}
/>
</mesh>
</>
);
};
const ComputersCanvas = () => {
// Define a state variable named 'isMobile' and a function to update it named 'setIsMobile'
const [isMobile, setIsMobile] = useState(false);
// Use the useEffect hook to perform side effects in functional components
useEffect(() => {
// Create a media query that checks if the screen width is at most 500px
const mediaQuery = window.matchMedia("(max-width: 500px)");
// Set the initial value of the 'isMobile' state variable based on the media query result
setIsMobile(mediaQuery.matches);
// Define a callback function to handle changes to the media query
const handleMediaQueryChange = (event) => {
// Update the 'isMobile' state variable based on the new media query result
setIsMobile(event.matches);
};
// Add the 'handleMediaQueryChange' callback as a listener for changes to the media query
mediaQuery.addEventListener("change", handleMediaQueryChange);
// Clean up function: this function will be called when the component is unmounted
return () => {
// Remove the 'handleMediaQueryChange' listener when the component is unmounted
mediaQuery.removeEventListener("change", handleMediaQueryChange);
};
}, []); // An empty dependency array means this effect runs only after the initial render
return (

};
export default ComputersCanvas;
提前感谢您的帮助。
我查看了其他堆栈溢出问题,虽然我能够解决其他 3D 组件问题(是的!),但我无法找到上述解决方案。 我也尝试隐藏该组件,一旦我这样做,代码就可以正常工作,但是一旦我取消注释它,页面就会看起来像空白,如下图所示。
