I’m proud to announce I’ll be part of [International Pascal Congress](https://pascalcongress.com/), an event taking place _July 3-7 (this year, 2023)_ in the _Salamanca city (Spain)_.

You can register now (see [the registration page for prices](https://pascalcongress.com/registration.html))! Note that 1st early registration phase is only up to the _10th April_, and registering early costs less.

The program is full of talks and presentations that should be appealing to every Pascal user, coming both from FPC (e.g. _Michael Van Canneyt_ will give a talk _“Free Pascal: Past, Present and Future”_) and Delphi (e.g. _Marco Cantù_ will give a talk _“Delphi’s Object Pascal Evolution”_). See the [Plenary talks](https://pascalcongress.com/keynote_speakers.html) for details.

And of course from yours truly 🙂 I will be:

1. Making one of [keynote lectures](https://pascalcongress.com/keynote_speakers.html) titled _“Developing games and graphic visualizations in Pascal”_.

This will be an overview of the most important concepts of developing graphic applications, including in particular 3D visualizations and games, and how to do them in practical Pascal applications.

We will start with an overview of APIs, like _OpenGL(ES)_ and _Vulkan_, and their most important concepts like _shaders_.

We will show how to use these graphic APIs from Pascal, from various Delphi (like Firemonkey 3D) and Lazarus (like TOpenGLControl) components.

Then we will move to high-level libraries and game engines, like

  - [Castle Game Engine](https://castle-engine.io/) ([support us on Patreon](https://www.patreon.com/castleengine)), 

  - [Apus Game Engine](https://github.com/Cooler2/ApusGameEngine) ([support Ivan Polyacov on Patreon](https://www.patreon.com/ApusGameEngine)), 

  - and [BeRo projects](http://www.rosseaux.net/) ([RNL](https://github.com/BeRo1985/rnl), [Kraft](https://github.com/BeRo1985/kraft), [PasVulkan](https://github.com/BeRo1985/pasvulkan); support [support Benjamin Rosseaux on Patreon](https://www.patreon.com/bero/)). 

Finally I will talk about the important features you should consider when choosing a library (and creating your own): 3D model formats (how and why are formats like [glTF](https://castle-engine.io/gltf) and [X3D](https://castle-engine.io/vrml_x3d.php) developed), PBR (physically based rendering), mixing 2D and 3D, physics and more.

2. I will give a course [Developing games using Castle Game Engine](https://pascalcongress.com/courses.html).
