我使用默认的 laravel 文件夹结构和文件系统public：

'public' => [
    'driver'     => 'local',
    'root'       => storage_path('app/public'),
    'url'        => env('APP_URL') . '/storage',
    'visibility' => 'public',
],

一切都在 docker 上运行，完整的 laravel 文件夹安装到/var/www/html：

#... Laravel PHP-FPM service definition
  volumes:
    - "./:/var/www/html"
#...

当我运行php artisan storage:link然后cd /var/www/html/public我ls -la看到符号链接存在：

lrwxr-xr-x 1 root root 32 May 5 11:19 storage -> /var/www/html/storage/app/public

如果我然后检查链接的文件夹是否也存在于容器中，cd /var/www/html/storage/app/public则一切都按预期存在。

另外，直接检查时ls -la /var/www/html/public/storage/它会显示链接文件夹的内容。所以从符号链接的角度来看一切都正常

# ls -la /var/www/html/public/storage/
total 512

我正在向场景中添加一架飞机，如下所示：

// Camera
this.three.camera = new THREE.PerspectiveCamera(45, window.innerWidth/window.innerHeight, 0.1, 60);
// Plane
const planeGeometry = new THREE.PlaneBufferGeometry(1,1,this.options.planeSegments,this.options.planeSegments);
const planeMat = new THREE.ShaderMaterial( ... )
this.three.plane = new THREE.Mesh(planeGeometry,planeMat);
this.three.scene.add(this.three.plane);

很基本。我不是试图找出如何在 Z 轴上移动平面以填充浏览器视口。为了那个原因，

// See attachment "solving for this" is closeZ
const closeZ = 0.5 / Math.tan((this.three.camera.fov/2.0) * Math.PI / 180.0);
this.uniforms.uZMax = new THREE.Uniform(this.three.camera.position.z - closeZ);

所以现在我知道在我的着色器中我可以向 Z 添加多少来使平面填充视口。顶点着色器看起来像这样：

uniform float uZMax;

void main() {   
    vec3 pos = (position.xy, uZMax);
    gl_Position = projectionMatrix * modelViewMatrix * vec4( pos, 1 ); …

我正在按照本指南安装 valet-plus。不过，brew 文件中似乎有问题。运行brew install valet-php@7.4 --build-from-source安装命令时，出现以下错误：

我的THREE.Points对象有以下设置：

        this.particleGeometry = new THREE.BufferGeometry()
        this.particleMaterial = new THREE.ShaderMaterial(
            {
                vertexShader: vshader,
                fragmentShader: fshader,
                blending: THREE.AdditiveBlending,
                depthWrite: false,
                uniforms: {
                    uTime: new THREE.Uniform(0),
                    uMousePosition: this.mousePosition
                }
            }
        )

然后一些代码将点放置在BufferGeometry球体上。那工作正常。

我还设置了一个 Raycaster 来跟踪与隐藏平面相交的鼠标位置，然后相应地更新制服uMousePosition。这也很好用，我将鼠标位置发送到我的顶点着色器。

现在我试图让离d鼠标有一定距离的粒子远离它，当然最接近的粒子被推开，并且还将重力施加回它们的原始位置以在一段时间后恢复一切。

所以这是我的顶点着色器中的内容：

void main() {
float lerp(float a, float b, float amount) {
    return a + (b - a) * amount;
}

void main() {
    vec3 p = position;

    float dist = min(distance(p, mousePosition), 1.);

    float lerpFactor = .2;

    p.x …
