Currently, I am tackling a project in Three.js where I am in need of setting up a third-person camera that tracks a 3D model as it navigates through the scene. Despite having a basic framework with animations and controls, I am encountering difficulties in getting the camera to properly follow the model's movements. Here is a breakdown of what I am aiming for and the challenges I am facing:
Summary of the Issue:
My goal is to have the camera trail the model from a third-person perspective. Specifically, as the model traverses in various directions (forward, backward, left, right), the camera should consistently follow the model while maintaining a fixed distance and orientation.
Current Setup:
<script setup>
import * as THREE from 'three';
import { OrbitControls } from 'three/addons/controls/OrbitControls.js';
import { GLTFLoader } from 'three/examples/jsm/loaders/GLTFLoader.js';
import { onMounted, ref } from 'vue';
const container3D = ref(null);
onMounted(() => {
// Code for initializing the scene, camera, loading models, setting up animations, and handling controls
});
</script>
Problematic Situation:
The camera does not currently follow the model's movements as expected. It remains stationary and does not adjust its position or orientation based on the model's actions.
Attempts Made:
I have ensured the correct setup of the camera and renderer. I have implemented animation controls for manipulating the model's movements. I have utilized OrbitControls to manage the camera's view.
Inquiries:
How can I tweak the camera configuration to track the model from a third-person perspective? What modifications should be made in the code to ensure that the camera maintains a consistent distance from the model throughout its movement? Any advice or recommendations on resolving this issue would be highly valued. Thank you!
