Three.js | Vue.jsThree.js实现第一个三维界面 | HTTP Client library

I'm using BufferGeometry to handle meshes with lots of vertices, faces and normals, which I supply via TypedArrays. During rendering, the Scene and its Mesh is constructed without any warnings or errors in the console. With BoxHelper I've constructed a Bounding Box around the mesh.

Now the strangest thing happens: Although the Bounding Box is perfectly correct, the faces/vertices are cut off somewhere in the middle.

To see what I mean, here is the comparison of two models rendered with a python script (left) and rendered with Three.js (right):

The code I've used for this task can be found here in this pastebin. Any help is highly appreciated.

I recently found out there is a very handy method in three-box for placing three.js objects on the map which is "projectToworld".

While trying to place my three.js objects using the method, I realized that the Vector3 the method returns are really huge and not on the map.

According to the documentation of threebox, it says

projectToWorld

tb.projectToWorld(lnglat) : THREE.Vector3

Calculate the corresponding THREE.Vector3 for a given lnglat. It's inverse method is tb.unprojectFromWorld.

So I decided to use this method to locate my animated object in three js canvas. But what the methods returns are really huge.

So as I expected, these values don't place the three objects on the map and all the objects disappeared because they presumably are placed at very distant locations.

How do I fix this issue?

I made a minimal code to demonstrate this issue as below.

i'm new at babel and browserify, I have a problem with transpile with browserify and babel, i've installed the threejs package and add

I have a question regarding texture3D. I am new to the 3D world. I was looking at volume rendering and came across this example https://github.com/mrdoob/three.js/blob/master/examples/webgl2_materials_texture3d.html

My question is about these three lines.

I am selecting vertices from a point cloud using angular and three.js. I have been trying to label a selected vertex with its x,y,z information. I have been using these resources in my attempt:

1. three.js Vector3 to 2D screen coordinate with rotated scene
2. https://threejsfundamentals.org/threejs/lessons/threejs-align-html-elements-to-3d.html

and I can't get either to work as described.

My code currently is:

I have two problems with three.js on my WordPress page.

First: I cannot import GLTFLoader. The error message says: "Uncaught TypeError: Failed to resolve module specifier "THREE/examples/jsm/loaders/GLTFLoader.js". Relative references must start with either "/", "./", or "../"." However while I put "/" it tries to import from my server and if I put "//" it's looking for https://three/examples/. Which is also not working.

Here You can see part of my code:

I've downloaded the three.js from it's official site and I'm try to run very basic file, I'm getting weird error but when I replace the three.js file import with CDN it starts to work. Please help me in starting the file from local.

I am loading a three.js gltf file onto my page, and would like to use a p5 sketch as a preload animation. It's a simple animation I made and so should serve decently while the heavy gltf loads. Currently I am using my loading manager to set a boolean trigger, but it simply does not get triggered by three js.

Here is some sample code that illustrates the interactions.
