Description: # Dash VTK
        
        *Dash VTK lets you integrate the `vtk.js` visualization pipeline directly into your Dash app. It is powered by [`react-vtk-js`](https://github.com/Kitware/react-vtk-js/).*

        ## Getting started
        
        ### Quickstart (Python)
        
        First, install the library through `pip`:
        ```
        pip install dash-vtk
        ```
        
        Then, create a file called `app.py` and add the following example:
        
        ```python
        import dash
        import dash_vtk
        import dash_html_components as html
        
        app = dash.Dash(__name__)
        
        app.layout = html.Div(
            style={"width": "100%", "height": "calc(100vh - 16px)"},
            children=dash_vtk.View([
                dash_vtk.GeometryRepresentation([
                    dash_vtk.Algorithm(
                        vtkClass="vtkConeSource",
                        state={"resolution": 64, "capping": False},
                    )
                ]),
            ]),
        )
        
        if __name__ == "__main__":
            app.run_server(debug=True)
        ```
        
        Now, simply run the app:
        ```
        python app.py
        ```
        
        For a more detailed example, see `usage.py`.
        
        ### Quickstart (R)
        
        First, install the package from GitHub (the package is not yet available via CRAN):
        ```
        remotes::install_github("plotly/dash-vtk")
        ```
        
        then, create your component and add it to your layout:
        
        ```r
        library(dash)
        library(dashVtk)
        library(dashHtmlComponents)
        
        app <- Dash$new()
        
        app$layout(htmlDiv(
            style = list("width" = "100%", "height" = "calc(100vh - 16px)"),
            children = vtkView(list(
                vtkGeometryRepresentation(
                    vtkAlgorithm(
                        vtkClass = "vtkConeSource",
                        state = list("resolution" = 64, "capping" = FALSE),
                    )
                )
            )
        )
        
        app$run_server()
        ```

        ## Running the demos
        
        First clone the project (replace `<name>` with the desired demo):
        
        ``` bash
        git clone https://github.com/plotly/dash-vtk.git
        cd dash-vtk/demos/<name>/
        ```
        
        Create a venv and install the requirements:
        ```bash
        python -m venv venv
        source venv/bin/activate  # for Windows, use venv\Scripts\activate.bat
        pip install -e ../../  # IMPORTANT! If you skip you will get the pip version of dash-vtk
        pip install -r requirements.txt
        ```
        
        Run the demo:
        ```bash
        python app.py
        ```
        
        ### Python environments
        
        Depending on your Python environment, you may run into deployment issue related to the vtk version that get pulled in.
        
        Ideally we want a version of vtk equal or newer than 9. When using such version of VTK, `dash-vtk` won't even try to load the rendering module of VTK and if OpenGL is not available on your system everything will still be fine.
        
        On the other hand, if you are running python-3.6 and/or pip-18 or less and you don't upgrade your pip version, you will only be able to use `vtk<=8.1.2`. With vtk 8, there is no way to prevent the loading of the GL library which means that you will have to install libGL on your system, or you will run into errors like this:
        
        ```
          File ".../python/lib/python3.6/site-packages/vtkmodules/all.py", line 29, in <module>
            from .vtkRenderingOpenGL2 import *
        ImportError: libGL.so.1: cannot open shared object file: No such file or directory
        [2021-02-08 18:36:15 +0000] [10] [INFO] Worker exiting (pid: 10)
        ```
        
        or this:
        ```
          File ".../python3.7/site-packages/vtk/__init__.py", line 12, in <module>
            from .vtkOpenGLKit import *
          File ".../python3.7/site-packages/vtk/vtkOpenGLKit.py", line 9, in <module>
            from vtkOpenGLKitPython import *
        ModuleNotFoundError: No module named 'vtkOpenGLKitPython'
        ```
        
        Heroku and Dash Enterprise handle it is slightly different because you will have to install `libgl1-mesa-glx` via some `apt` files. In the case of Heroku, you will have to use a [buildpack](https://elements.heroku.com/buildpacks/heroku/heroku-buildpack-apt) and add `libgl1-mesa-glx` to a `Aptfile` located in the root of your project. In the case of Dash Enterprise, you do not need to change the buildpack (it is handled automatically) but you will need to add `libgl1-mesa-glx` to a `apt-packages` file instead of `Aptfile`; see [this app](https://github.com/plotly/dash-sample-apps/blob/master/apps/dash-vtk-explorer/apt-packages) as an example.
