Fill Area between Lines with color - Three.js

由 旧巷老猫 提交于 2020-05-27 04:58:50
问题 I have series of lines, and I need to color all the area beneath or between lines with a color. For the sake of simplicity, I have created a snippet with closed lines. In reality, i have a program that draws many lines (like a stock market graph) , and I need to color all the area below the graph. see also the screenshot. would appreciate any help or even new approach that maybe I need to take. <html> <head> <title>My first three.js app</title> <style> body { margin: 0; } canvas { width: 100%

Getting uneven click-detection on 3d-objects on mapbox with raycaster

由 瘦欲@ 提交于 2020-05-17 06:05:41
问题 I am using raycaster in mapbox with 3d-objects. I need to detect the click on the 3d-object.But When I click on the object I get a empty raycaster.intersectObject (array) sometimes and filled array sometimes, rather it should always have the 3d object that I have clicked. I have a simple map as explained here. I have only added the raycasting part to it to keep it as simple as possible. Here is my code. var longitude, latitude, diff, map, destLongitude, destLatitude, distFrmlast = 0; var

Add text with geometry in threejs

由 青春壹個敷衍的年華 提交于 2020-05-16 08:06:29
问题 I want to attach text to the bottom part of the rings (where the cuts are) as you can see in the image below. You can see the code I am using to draw the rings. I want to write the radius (40m, 30m, 20m) where the cuts are and I would prefer that they are merged because I will be zooming them in and out and want them to stay connected to the rings. // Rings // 40m ring const geometry40m = new THREE.RingGeometry(35, 35.6, 30, 8, 4.85, 6); geometry40m.lookAt(this.CAMERA_POSITION); const

THREE.js - Merging / Instancing Multiples of The Same GLTF Model, Without Shader Material..?

由 こ雲淡風輕ζ 提交于 2020-05-14 09:09:42
问题 I am using the code below to load and clone a GLTF model. In practice this works, however it is way too resource heavy and the model is around a 2mb. It has no textures and the materials are a single MeshPhongMaterial. I understand two ways to optimise this are to merge them into one mesh instead of cloning, however following numerous attempts (such as iterating within the load function with a for loop), I haven't been able to successfully do this. The second being instancing, however from a
