This guide helps you get started with Python for 3D Data Science. It covers the essential steps in setting up your environment, including the resources you’ll need and the workflow to follow. By the end of this guide, you’ll have a working environment set up and be ready to delve into 3D data science with Python. The first result is a synthetic point cloud shape generator.
1. The 3D Python Setup
This guide assumes you are a beginner with little to no experience with Python. The goal is to get you up and running with a Python environment specifically designed for working with 3D data.

3. The 3D Python Environment Workflow 🗺️
The following steps will guide you through setting up your 3D Python Environment for 3D data science:
- Environment Setup with Miniconda: Download and install Miniconda following the instructions on the Anaconda website.
- Package Manager and Using Pip: Use pip, the recommended package manager for Python environments, to install the necessary libraries.
- Installing Libraries: Install essential libraries like NumPy, SciPy, scikit-learn, Matplotlib, and Open3D using pip.
- Installing an IDE: Install an IDE (Integrated Development Environment) like Spyder to write and execute Python code.
- Exploring the IDE: Familiarize yourself with the functionalities of the Spyder IDE.
- Structuring Your Code for First Applications: Organize your code using folders for code, data, and results.
- Your First Script: Create a Python script to generate a random point cloud and visualize it in 3D using Open3D.
After following this simple 7-step workflow, you will be able to generate simple 3D Shapes as point clouds, such as cubes, spheres, and planes.
The Code for these can be found on my Github Page (link in section 2). Below is a snippet:
import numpy as np
import open3d as o3d
def generate_random_point_cloud(num_points=5000, num_shapes=1):
# Initialize an empty list to store all points
points = []
# Generate multiple shapes
for * in range(num*shapes):
# Randomly choose a shape type
shape_type = np.random.choice(['sphere', 'cube', 'plane'])
# Calculate number of points for this shape
shape_points = num_points // num_shapes
if shape_type == 'sphere':
# Generate points on a sphere
radius = np.random.uniform(0.5, 1.0)
theta = np.random.uniform(0, 2*np.pi, shape_points)
phi = np.random.uniform(0, np.pi, shape_points)
x = radius * np.sin(phi) * np.cos(theta)
y = radius * np.sin(phi) * np.sin(theta)
z = radius * np.cos(phi)
elif shape_type == 'cube':
# Generate points in a cube
x = np.random.uniform(-1, 1, shape_points)
y = np.random.uniform(-1, 1, shape_points)
z = np.random.uniform(-1, 1, shape_points)
else: # plane
# Generate points on a plane (z=0)
x = np.random.uniform(-1, 1, shape_points)
y = np.random.uniform(-1, 1, shape_points)
z = np.zeros(shape_points)
# Generate a random center for the shape
shape_center = np.random.uniform(-5, 5, 3)
# Add the shape's points to the main list, offsetting by the shape's center
points.extend(np.column_stack((x, y, z)) + shape_center)
# Convert the list of points to a numpy array and return
return np.array(points)
#%% Random Experiments
# Generate random point cloud with 10000 points and 8 shapes
point_cloud = generate_random_point_cloud(10000, 8)
# Create Open3D point cloud object
pcd = o3d.geometry.PointCloud()
pcd.points = o3d.utility.Vector3dVector(point_cloud)
# Visualize the point cloud
