Any help would be greatly appreciated. Note A surface is defined by points connected to form triangles or polygones. Use this to change the extent of the object created. We call such data a scatter. The quickest way to create beautiful visualization with Mayavi is probably to interactively tweak the various settings. Which MayaVi version are you using? For this, we need: For simple structures such as orthogonal grids prefer the surf function, as it will create more efficient data structures.
Our data is often more than points and values: We use a Range type. Using the code from the magnetic field simulation, create a dialog that enable to move the 2 coils: See also Sources are described in details in the Mayavi manual. Different views on data: More details in the Mayavi documentation. Excercice Using the mlab. See also There are a few things to be aware of when doing dialogs with Mayavi.
In general, many properties of the various objects on the figure can be changed. If you create a vector fieldyou may want to visualize the iso-contours of its magnitude.
Just ran into the very same problem.
See also More details in the Mayavi documentation. For example, iso-contours of the magnitude are coded as: Excercise Visualize this field. Filters apply a transformation to data, and can be added between sources and modules. You can reproduce these pipelines programmatically with the mlab. To make movies, or interactive application, you may want to change the data represented on a given visualization.
Full code of the example: These axes look much more professional and are easier to read than the default MayaVi axes. The important point here is that a Mayavi scene is added as a specific Traits attribute Instance. Any help would be greatly appreciated. The resolution of the glyph created. You can now add labels and annotations using text3d Very inelegant and brute force, but works in a pinch. Mayavi is an interactive 3D plotting package. This option is usefull to reduce the number of points displayed on large datasets Must be an integer or None.

Second, the dialog is defined by an object inheriting from HasTraits, as it is done with Traits. Must be a float. Joe Kington k 40 Data sources corresponding to scatters can be created with mayavi. The view of this dialog is defined by the view attribute of the object. Create a contour for instance of the magnetic field norm by using one of those functions and adding the right module by clicking on the GUI dialog. The best axes I could create looked something like this Quiz Why is it not possible to add a VectorCutPlane to the vectors created by mayavi.
I would like the axes to look something like this Tip Full code of the example: By right-clicking on the nodes of the pipeline, you can add new modules. Post as a guest Name. There are a few things to be aware of amyavi doing dialogs with Mayavi. First, the curve function is used to compute the coordinate of the curve we want to plot.
Sign up or log in Sign up using Google. For spheres, for instance, this is the number of divisions along theta and phi.
Sign up using Facebook. The quickest way to create beautiful visualization with Mayavi is probably to interactively tweak the various settings. For this, we need:. Note A surface is defined by points connected to form triangles or polygones.
We call such data a scatter. If you have built a visualization, using the mlab plotting functions, or the mlab.

Please read the Mayavi documentation. Suggestions If you compute the norm of the vector field, you can apply an isosurface to it. A set of data points measured at random positions in a random order gives rise to much more difficult and ill-posed interpolation problems: However, these do not look very professional if I were to give a presentation or put these on a poster.
python – How to plot proper 3D axes in MayaVi, like those found in Matplotlib – Stack Overflow
Created ploh Sphinx 1. Sign up using Email and Password. For the interaction with the user for instance changing the view with the mouseMayavi needs some time to process these events. I hacked a bad workaround by not displaying the mayavi axes, but plotting the axes I needed myself using plot3d.
