Hi, I am trying to install mayavi for pysph on Ubuntu 22.04. I cloned the mayavi git repository, installed vtk using 'sudo apt-get -y install python3-vtk9', and installed PyQt5 using pip. However, there is no requirements.r in the mayavi folder. And when I run 'pip install mayavi', I get the error: "ImportError: cannot import name 'Sequence' from 'collections' (/usr/lib/python3.10/collections/init.py) [end of output] note: This error originates from a subprocess, and is likely not a problem with...

In my Mayavi geometry which I create using mlab.triangular_mesh(), I want to create a 'heat map' type effect by scaling individual element coloration within a given colormap using externally supplied data (think: heat, stress, surface curvature, whatever) This is the only example I have found which approaches the topic, but I'd like your input if: 1) there is a better way to do it (using scalar field in triangular_mesh()?); and 2) how to relate the scalar input to a specific color map. import numpy...

It looks like this forum is dead, but in case anybody googles this question I'm providing below a solution that I managed to work out myself. The solution was to insert the following code at the top of my python module imports: from traits.etsconfig.api import ETSConfig ETSConfig.toolkit = 'qt4' For some weird reason, it seems that specifying the ETSConfig.toolkit parameter as 'qt4' actually denotes qt4 and qt5, but specifying qt5 doesn't work even if your are using pyqt5.

I'm having diabolical trouble trying to get mayavi mlab to work in a miniconda env. I've tried all sorts of configurations (py39, py38, p37, py36, qt4, qt5) but nothing seems to work. I've tried installing packages with conda and pip, but neither works. Every time I try to import mlab in ipython or a Jupyter notebook I get the following runtime error: RuntimeError: No pyface.toolkits plugin found for toolkit qt5 Here is an example of the creation of one of my miniconda envs: conda create -n mayavi...

I'm using mayavi mlab in notebook cells in Jupyterlab to view 3D isosurfaces. I quite like it because it renders isosurface scenes very efficiently, much quicker than plotly. However, mlab seems to run sychronously so that I can only view one mlab scene at a time. Can anyone tell me how to run mlab asynchronously from a notebook cell? In other words, I want to launch an mlab scene from a Jupyterlab notebook cell and then proceed to executing the next cell without having to shut down the mlab sce...

Hello, I have set of points(x,y,z) from which I have created a mesh usng following code, from that I have get the triangular mesh. Now I want to know the which points were used to create traingles(faces). Is there any command which can give me that data from mesh object. Code: from plyfile import PlyData,PlyElement import numpy as np from mayavi import mlab from tvtk.api import tvtk plydata = PlyData.read('/home/local/ALGOANALYTICS/rchandgude/rupesh_work/NTT_dewrapping/sample_data/Envelope/Env.ply')...

I have a Tkinter GUI and would like to embed mayavi images inside the frame. Is it possible to do that? Is there any examples which does support this function?

How I can load multiple vaariables/scalars on a mayavi line and represent them as a tube ? in: src = mlab.pipeline.scalar_scatter(x, y, z,S) ## S should be the same size of z! ## src.mlab_source.dataset.lines = connections mlab.pipeline.tube(src_line, ......)

Alright.. well failing that can someone direct me to a nice set of exercises to improve my ability in Mayavi?

This is a great example written by Prabhi Ramachandran and modified slightly by me. I would like to turn it into a function such that I can call it to place a single arrow (xyz)position, (RGB)color, (xyz)orientation and even (xyz) size. I would prefer a 3d arrow to a 2d arrow. My intention is to maintain an array of data, perform some calculations between the elements and generate a second array, this array will then call the above function to create a visualization, then the second set of data will...

In the project below I can control the size of the two windows on the screen. But how can I control the positions of the windows? I use jupyter notebook. Regards, Poul Riis Denmark import numpy as np from mayavi import mlab from math import * xx=np.linspace(0,1,201,endpoint=True) yy=xx2 zz=np.sin(2np.pi(xx+yy)) fig1 = mlab.figure(figure='Figur 1',size=(600, 300)) s1 = mlab.points3d(xx, yy, zz,scale_factor=0.02,color=(1,0,0)) mlab.axes(s1, ranges = [min(xx), max(xx), min(yy), max(yy), min(zz), max(zz)])...

Dear All, I have the following codes, and have problems as follows: ・The plot is not displayed until the cmap is changed, Can I fix it? ・The name of the windows is "Edit properties", can I change it to Mayavi scence? def show(self): print "Plotting...", mlab.view(distance = 'auto') mlab.outline( line_width=1.0, opacity=0.3 ) mlab.axes() mlab.show() def __init__(self, arg1, arg2, arg3, arg4): HasTraits.__init__(self) self.file_peaks = arg1 self.file_pat_dist = arg2 self.file_hess_dist = arg3 self.file_id_dist...
