Once your PyQGIS script generates a .obj file, you need a two-step conversion:
Using MeshLab (CLI):
meshlabserver -i output.obj -o output.u3d -s export.mlx
Using pandoc + LaTeX to embed U3D into PDF:
\documentclassarticle
\usepackage[3D]movie15
\begindocument
\includemovie[3Daac=60.000, 3Droll=0.000, 3Dc2c=0 0 1, 3Droo=0.000, 3Dcoo=0 0 1]{}{}output.u3d
\enddocument
If this sounds complex, that is because it is. The true PyQGIS programmer automates this shell execution.
Scenario: A Python script runs nightly, pulls new raster data from a PostGIS database, updates a QGIS project, and emails a PDF report.

For Geographic Information System (GIS) professionals, there comes a tipping point where clicking buttons in a Graphical User Interface (GUI) simply isn't enough. You find yourself repeating the same processing tasks, manually exporting hundreds of maps, or struggling to customize QGIS to fit your specific workflow.
That is the moment you realize you need to learn PyQGIS.
If you have started this journey, you have likely heard of the definitive resource for the job: the PyQGIS Programmer's Guide. With the release of the 3rd Edition, updated for QGIS 3.x, this guide has become the "bible" for automating QGIS.
In this post, we explore why the 3rd Edition is essential, what you can expect to learn, and how it bridges the gap between GIS analyst and GIS developer.

Modern PDF workflows require embedded metadata (author, title, keywords). While QgsLayoutExporter does not directly set PDF metadata, you can post-process the PDF:
from pypdf import PdfReader, PdfWriter
reader = PdfReader("original.pdf")
writer = PdfWriter()
writer.append_pages_from_reader(reader)

Introduction
The PyQGIS Programmer's Guide 3 is a comprehensive guide for developers who want to create custom plugins and applications using the QGIS Python API. The guide provides an overview of the QGIS Python API, explains how to set up a development environment, and covers various topics such as working with maps, layers, and widgets.
Setting up the Environment
To start working with PyQGIS, you need to have QGIS installed on your system. You can download the latest version of QGIS from the official website. Once QGIS is installed, you need to set up a Python environment. The guide recommends using a virtual environment to manage dependencies and ensure that your Python environment is isolated from other projects.
Basic PyQGIS Concepts
The guide covers the following basic concepts:
Working with Maps and Layers
The guide provides examples of how to:
Creating Custom Plugins
The guide provides an overview of how to create custom plugins using PyQGIS. This includes:
Example Code
The guide provides many examples of code to illustrate the concepts and techniques covered. For example:
import qgis.core
# Create a new map
canvas = qgis.core.QgsMapCanvas()
# Add a layer to the map
layer = qgis.core.QgsVectorLayer("path/to/layer.shp", "My Layer", "ESRI Shapefile")
canvas.setLayer(layer)
# Style the layer
symbol = qgis.core.QgsSymbol(qgis.core.QgsSymbol.Marker)
symbol.setColor(qgis.core.QgsColor.red())
layer.setSymbol(symbol)
