How to insert google map in to three js plane
I am using three.js for my 3D view.
I am adding one plane, where I am able to set the map image. click to get plane image
var planeGeometry = new THREE.PlaneGeometry(this.planeWidth, this.planeHeight);
But I want to add map instead of map image on plane.I am not much aware about other maps so, that google map has been selected.
whether can we achieve this through three.js if Yes then how?

Add colorbar to 3d scatterplot in matplotlib
I want to add a colorbar to a 3d scatter plot. In 2d this is very easy:
x = range(10) y = range(10) c = range(10) plt.scatter(x,y,c=c) plt.colorbar()
In 3d however I don't get it to work:
z = range(10) fig = plt.figure() ax = fig.add_subplot(111,projection = "3d") ax.scatter(x,y,z,c = c) # same happens with ax.colorbar()
RuntimeError: No mappable was found to use for colorbar creation. First define a mappable such as an image (with imshow) or a contour set (with contourf).
How can I get a colorbar next to my 3d plot? plt.colorbar()
Study of a vector field
I have an input data with 6 columns where the three first are the position x, y, z and the rest are vector components of a vector field. I could only make a 3d graph with quiver3d of the mayavi library in python (x,y,z,px,py,pz) creating 6 numpy arrays x,y,z,px,py,pz just to visualize it.
It would be great to get a 3D graph by any mean where I could insert cut planes where the vectors that are contained on it would be shown, or planes where I could see a color map that would help me to understand its beahaviour. Any help?
Here is the input: https://pastebin.com/raw/pmGguxUc
Here is the code I used to get the visualization with quiver3d function. import numpy as np import mayavi.mlab as mlab
data = np.loadtxt("vectorfield.dat", dtype = float) dataTranspuesta=data.T x=dataTranspuesta y=dataTranspuesta z=dataTranspuesta px=dataTranspuesta py=dataTranspuesta pz=dataTranspuesta mlab.quiver3d(x, y, z, px, py, pz, line_width=0.7 ,scale_mode="vector" ,scale_factor=0.0045,mask_points=7 ,mode="arrow", colormap="seismic" ) mlab.show()
Load and control a 3D model (.ply format only)
That's my first question in StackOverflow so... Hello World!
I'm working in a catalog-like application. I made the list controls, parsers and all main front and back-end work… But the client now wants to change the PNG image for a 3D model of their products.
Anyone knows how to add a PLY reader which load the file and allows user to rotate it?
Thanks in advance.
Three.js: making bounding box
In my program, I am trying to make bounding box around a point cloud. I have calculated the opposite vertices for this purpose.
Here, documentation for BoxGeomtery is available. But I am not able to understand the constructor. Constructor takes width,height, depth as inputs. But what about location of the box. Where in the scene would this box be created?I want bounding box to be defined by two vertices I have.
WebGL – Stretching non power of two textures or adding padding
I'm using images of varying sizes and aspect ratios, uploaded through a CMS in Three.js / A-Frame. Of course, these aren't power of two textures. It seems like I have two options for processing them.
The first is to stretch the image, as is done in Three.JS – with the transformation undone when applied to the plane.
The second is to add extra pixels (which aren't displayed) due to custom UVs.
Would one approach be better than the other? Based on image quality, I'd imagine not doing any stretching would be preferred.
Can you customise the aframe raycaster to look like this
I want to add a dot where the raycaster intersects an object like this one in the picture. I know you can modify the line element of raycaster but I couldn't find a way to add a circle or change the one end of the line.
