This recipe helps you make 3D Volume plots using plotly

0

## Recipe Objective

Make 3D Volume plots using plotly.

Volume plot this shows many partial transparent isosurfaces for rendering the volume. The opacityscale parameter of this plot results in a depth effect and generates better volume rendering. Three-dimensional volume visualization is a method that allows one to observe and manipulate 3D volumetric data. It represents 3D objects in terms of surfaces and edges approximated by polygons and lines.

## Step 1 - Import libraries

``` import plotly.graph_objects as go import numpy as np ```

## Step 2 - Take Sample Data

``` x_data = np.linspace(-5, 5, 10) y_data = np.linspace(-6, 6, 12) z_data = np.linspace(-6, 6, 12) ``` ``` X, Y, Z = np.meshgrid(x_data, y_data, z_data) values = (np.sin(X**2 + Y**2))/(X**2 + Y**2) ```

## Step 3 - Plot graph

``` fig = go.Figure(data=go.Volume( x=X.flatten(), y=Y.flatten(), z=Z.flatten(), value=values.flatten(), opacity=0.2, )) fig.show() ```
