mayavi

I'm trying to make an animation with a sequence of datafiles in mayavi. Unfortunately i have noticed that camera doesn't lock (it is zooming and zooming out). I think it is happening because the Z componrnt of my mesh is changing and mayavi is trying to recalculate scales. How can I fix it? import numpy from mayavi import mlab mlab.figure(size = (1024,768),bgcolor = (1,1,1)) mlab.view(azimuth=45, elevation=60, distance=0.01, focalpoint=(0,0,0)) #mlab.move(forward=23, right=32, up=12) for i in range(8240,8243): n=numpy.arange(10,400,20) k=numpy.arange(10,400,20) [x,y] = numpy.meshgrid(k,n) z

I'm plotting a 3D mesh using mayavi's triangular_mesh method. The data describes a human silhouette laying face-down in 3D space (so the cmap can be used to denote distance from the camera). Here's the code used to generate the plot (the faces and vertices come from an external object, and there are far too many to show here): from mayavi import mlab import math import numpy as np import sys import os fig = mlab.figure(fgcolor=(0, 0, 0), bgcolor=(1, 1, 1), size=(1920, 980)) a = np.array(this_mesh.vertices - refC.conj().transpose()) # this_mesh is an object created from external data files this

Image gallery: http://imgur.com/a/qZkTW#qGj7I0H I just installed the new version of Canopy 1.3 from enthought. I opened up ipython, and I imported mayavi's mlab without issue. I then plotted a 3d sphere without issue using the following: import mayavi from mayavi import mlab mlab.points3d(1,1,1) mlab.show() And I get what I would expect (See figure #2 in gallery). I can then open up the scene editor without issue (see figure #1 in gallery), but when I try to open any other traits editors for anything else, I get a weird black background with no text: scalarscatter editor This issue affects all

I am currently working on a project that I have to simulate the magnetic field produced by a circular wire loop. I have written a piece of code and put it into a class, that works perfectly, but when I try to create a GUI using TaitsUI, it just fails. I have no idea how should I connect the one to the other. class Wireloop: x,y,z = np.mgrid[-10:10:150j, -10:10:150j, -10:10:150j] ### Transform to Cylindrial Polar r = np.sqrt(x**2 + y**2) # ρ in polar x_trans = x/r # cos(θ) y_trans = y/r # sin(θ) """ """ def __init__(self, R, I): self.R = R #radious self.I = I #DC current #Constants self.mew0 =

Is it possible to draw a image with 3 color channels using mayavi? According to the documentation for mayavi, mayavi.mlab.imshow can only handle images of shape (n x m). Method I had to make use of mayavi's custom colormaps, see http://docs.enthought.com/mayavi/mayavi/auto/example_custom_colormap.html . I made a colormap that consists of all the pixles in the original (n x m x 3) image as rows. I also included an alpha channel so that transparent png's can be displayed correctly. Next I used a grayscale image as a lookup table, with pixle values as indices to the original pixles stored in the

I'd like to either disable the VTK warning window or, better yet, catch them to handle with my application's logging system. My application is using an embedded mayavi view, and I don't want error windows popping up that I have no control over. The following code demonstrates the warning window. import numpy as np from mayavi import mlab x1 = np.array([1, 1, 2, 3]) y1 = np.array([1, 1, 4, 2]) z1 = np.array([1, 1, 5, 1]) mlab.plot3d(x1, y1, z1) mlab.show() Ok, I've done some research and discovered that vtk.vtkObject.GlobalWarningDisplayOff() will disable the window completely, which is nice.

OS: Linux Kubuntu 14.4.5 Python: Python 3.5.2 :: Continuum Analytics, Inc. I tried to install Mayavi into my anaconda environment: conda install -c menpo mayavi=4.5.0 conda install -c anaconda wxpython=3.0.0.0 conda install pyqt conda install qt But when I try to run the example from http://docs.enthought.com/mayavi/mayavi/auto/example_surface_from_irregular_data.html I get the error message ImportError: Could not import backend for traits with the explanation: Make sure that you have either the TraitsBackendWx or the TraitsBackendQt projects installed. If you installed Mayavi with easy
