在Angular中使用Three JS时，很容易出现渲染问题，特别是当尝试使用CSS样式更改画布大小和位置时。如果遇到画布渲染在错误位置的问题，可以尝试以下几种解决方法。

1. 设置画布大小和位置

在Component中，可以使用ViewChild获取Canvas元素并设置其大小和位置，如下所示：

import { Component, ViewChild, ElementRef } from '@angular/core';
import * as THREE from 'three';

@Component({
  selector: 'app-three-canvas',
  template: '',
  styleUrls:['./three-canvas.component.css'] 
})
export class ThreeCanvasComponent {
  @ViewChild('canvas') canvasRef: ElementRef;

  private scene: THREE.Scene;
  private camera: THREE.PerspectiveCamera;
  private renderer: THREE.WebGLRenderer;
  private mesh: THREE.Mesh;

  ngAfterViewInit(): void {
    this.init();
    this.animate();
  }

  private init(): void {
    const width = this.canvasRef.nativeElement.clientWidth; //获取canvas宽度
    const height = this.canvasRef.nativeElement.clientHeight; //获取canvas高度

    //创建场景
    this.scene = new THREE.Scene();

    //创建相机
    this.camera = new THREE.PerspectiveCamera(75, width / height, 0.1, 1000);
    this.camera.position.z = 5;

    //创建网格
    const geometry = new THREE.BoxGeometry();
    const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
    this.mesh = new THREE.Mesh(geometry, material);
    this.scene.add(this.mesh);

    //创建渲染器
    this.renderer = new THREE.WebGLRenderer({
      canvas: this.canvasRef.nativeElement //注意这里不要再document中获取canvas
    });
    this.renderer.setSize(width, height);
  }

  private animate(): void {
    requestAnimationFrame(() => this.animate());
    this.render();
  }

  private render(): void {
    this.mesh.rotation.x += 0.01;
    this.mesh.rotation.y += 0.01;
    this.renderer
