I am using Cesium to display a strictly 2D map in the browser (wrapped in React using the Resium library).
I am interested in giving the user the option to draw lines\polygons, and to measure the distances between two points or the area withing the polygon.
Basially, I want precisely this OpenLayeres example, but in Cesium: https://openlayers.org/en/latest/examples/measure.html
How would one go about doing it?
Thank you
I was doing some research on cesium drawing tool library.
It wasn't same as the one you asked but you can use it for your need. you can use for 2D and 3D maps. it gives all basic functionalities like draw circle, polygon, add marker, draw line, calculate distance etc.
I have found cesium-draw the library for the VUE.
[cesium draw ](https://www.npmjs.com/package/cesium-draw)<br>
If you can work with Angular their is a lot of cesium sport in angular so you can use
[angular-cesium](https://angular-cesium.com/)
if you have found any thing else please do share I love to see.

I’ve been stuck for days, and couldn’t figure it out.
I’m trying to put a small graphic (as in Team Badge, and player’s number at the back) onto a basketball jersey. I can’t use Texture as anything I specified will cover the whole jersey.
From this https://threejs.org/examples/#webgl_decals I believe decal is the way to go. What I don’t understand is that I need to shove a Mesh into the Constructor of DecalGeometry. What kind of mesh should I use? Not the mesh of the basketball jersey?
Is this the right step?
get the upload of PNG from browser
create DecalGeometry using an arbitrary Geometry (may be a square?)
specify some material (I want it to be transparent)
create a new mesh using the above DecalGeometry and material (I can’t figure out what values to use for the decal projector…)
load the PNG into a Texture
load the basketball jersey’s Mesh
merge the basketball jersey’s Mesh with the new Mesh containing the DecalGeometry
Also, how do I control the size of the graphic inside the DecalGeometry? As the graphic has color, I’m not sure if the basketball jersey’s color will affect the graphic and make the graphic look broken?
Thanks a lot!
I would like to place a hairstyle after facial landmark detection. I'm able to render 2D images properly. I would like to render 3D model. I thought of using SceneKit to render 3D model. I would like to know how Instagram, snapchat and other face filter apps are rendering 3D models. I observe SceneKit coordinate system is different from UIKit coordinate system. I have googled but couldn't find the conversion of coordinate system. Could anyone help. Thanks.
Look for worldUp and simdWorldUp instance properties to understand how ARKit constructs a scene coordinate system based on real-world device motion (also, you can inspect ARConfiguration.WorldAlignment enum).
Please, look at this SO post: Understand coordinate spaces in ARKit for complete info.
And remember, ARAnchor is your best friend when placing 3D object. Click here

I´m working with Leaflet.js and I have a lot of markers but I want to get a polygon drawn automatically containing a specific group of markers.
There´s an image:
Every marker has a specific radio, so if a use it, would be like this:
but I don't want that, I want an area that contains markers, I don't know how can I do that.
You might want to create a convex hull.
https://gis.stackexchange.com/questions/215137/how-to-create-a-convex-hull-with-leaflet-points:
"The easiest way to do this with javascript is to use Turf.js's convex functionality."

i'm trying to create a 3D animation using WPF. To modelize a form i see that we can use PerspectiveCamera or matrixCamera. What's the difference between the both?
Perspective camera makes objects farther away look smaller, like what we see in real life or through a camera zoom lens. You can achieve the same thing using a matrix camera, but you can also do a lot more. The perspective camera and orthogonal camera are both special cases of the more general matrix camera. With a matrix camera, you could create a perspective in one dimension different from the other, like a panorama view. It requires more work than the other camera types to do the same thing, but has more possibilities.
I am new to Gtk and want to do simple drawing of shapes like circles and rectangles. I was looking at the gnome tutorial and the hello word example. However the curves section is undocumented. I was wondering if someone could point me in the right direction as to what should I look at, and maybe if I need to include some other supplementary library to draw?
The preferred drawing API in GTK 2 and 3 is Cairo. But if you need to develop a diagram program, with nodes that can react to events, you will need also to use a canvas, like GooCanvas.
Check out http://developer.gnome.org/gtk3/3.2/GtkDrawingArea.html about the GtkDrawingArea, plus http://developer.gnome.org/gdk/stable/gdk-Drawing-Primitives.html about Gdk-Drawing-Primitives and you are on the go.
You might also go a bit further by using this link and check out Cairo directly http://www.cairographics.org
