# Jupyter-Dash-VTK-Viewer (jdvv)
![image](images/mtsthelens.png)
## Intro and Motivation
There are an ever growing number of 3d visualization tools in python and for jupyter. In my opinion [VTK](https://vtk.org/) by [Kitware](https://github.com/Kitware) provides the most complete set of tools for this purpose. The learning curve is a bit steep and the syntax isn't always particularly pythonic (often the underlying C++ bleeds through) but it is top notch. For those wanting a bit more user friendly and pythonic "batteries included" approach, have a look at [PyVista](https://www.pyvista.org/).

The motivation for this small vtk-viewer is to make viewing vtk objects easier from *within* jupyter lab. PyVista and VTK both offer a great viewer that can be launched external to jupyter lab in a QT window and this works great. The purpose of this package is to provide a similar experience within jupyter lab by taking advantage of the [dash-vtk](https://github.com/plotly/dash-vtk) suite of components.

## TL;DR
View VTK (or PyVista) objects either inline or in a separate tab within Jupyter Lab. A handful of controls are provided.

## Quickstart

`pip install jdvv`

A Basic example

```python
from jdvv import viewer
import pyvista as pv

# make a simple vtk object
cyl = pv.Cylinder()

# give it a name to be used in the viewer controls
cyl.name = "my cylinder"

# view inline
viewer.inline(cyl)

# view in a new tab within juptyer lab
viewer.tab(cyl)

# view externally in a separate browser tab
viewer.external(cyl)
```

## Features
* view inline, tab without needing to leave Jupyter Lab or view as an external browswer tab
* view multiple objects, separate controls for each
* Controls
    * visibility on/off
    * color & oppacity for objects with no associated data
    * Select color map, set min/max and opacity for object with attached arrays
    * change point size
    * select surface representation (wireframe, surface, volume)
    * Change background colors
