🎮 Welcome to my portfolio. I'm Nicolás Bertoa, a C++ developer specialized in Unreal Engine with 15+ years of professional experience at DreamWorks and Sony. Here I share technical demos, personal projects, and experiments. Check out my Demo Reels or explore my latest work below 👇
I have begun to upload to youtube a CG Course I was working on some months ago. The plan is to learn new stuff about the theory behind real-time computer graphics and upload new videos explaining them. I am recording them in Spanish only. The topics covered for now are the following:
1 – The RGB Color Model
2 – The Graphics Pipeline
3 – Geometry Space Transformation
4 – Geometry Representation
5 – Textures
6 – Rasterization
I have begun to upload to youtube a 3D Math Course I was working on some months ago. The plan is to learn new stuff about the 3D math used mostly in Computer Graphics and upload new videos explaining them. I am recording them in Spanish only. The topics covered for now are the following:
1 – Cartesian Coordinates and Number Systems
2 – Trigonometry
3 – Point and Vector – Part 1
4 – Point and Vector – Part 2
5 – Multiple Coordinate Spaces
6 – Matrix Basics
7 – Matrix Multiplication
8 – Matrix Determinant
9 – Matrix Inverse
10 – Scale Matrix
11 – Orthographic Projection Matrix
12 – Reflection Matrix
13 – Shearing Matrix
14 – Translation Matrix
15 – Rotation Matrix
16 – Euler Angles
I have begun to upload to youtube a C++ course I was working on some months ago. The plan is to learn new stuff from C++11, 14 and 17 (and so on), and upload videos explaining them. I am recording them in Spanish only. The topics covered for now are the following:
1 – Build Process and Basics
2 – Types and Declarations
3 – Pointers and References
4 – Flow Control
5 – Memory Model
6 – Functions
7 – Object-Oriented Features
8 – Operator Overloading
9 – Inheritance and Composition
10 – Inheritance and Polymorphism
11 – Multiple Inheritance and Casting
12 – Templates
13 – STL Containers and Iterators
I want to implement anti-aliasing in BRE, but first, I want to explore what it is, how it is caused, and what are the techniques to mitigate this effect.
In the previous post, we talked about Rasterization. Now, we will see aliasing and anti-aliasing in depth. In the next post, I am going to describe which anti-aliasing technique I choose for BRE and how I implemented it.

I want to implement anti-aliasing in BRE, but first, I want to explore what it is, how it is caused, and what are the techniques to mitigate this effect. That is why we will talk about Rasterization in depth in this post. Next post, will be about aliasing and anti-aliasing.

In this post from Lighting Series, we are going to talk about Photometry. The previous post in this series is Lighting Series Part 4 – Irradiance and Radiant Intensity.
In this post from Lighting Series, we are going to talk about Irradiance and Radiant Intensity. The previous post in this series is Lighting Series Part 3 – Radiance. In the next post, we are going to talk about Photometry.
The SI System (Système International d’unites) defines six radiometric units used for describing the radiation coupling between a light source and an optical system. The most commonly used units are: Radiant Flux, Irradiance, and Radiance.

When I begun studying real-time computer graphics, I did it with books about graphics APIs like DirectX 9, 10, 11 and 12. In these books, the computer graphics theory was explained correctly but deepening only the necessary.
Nowadays, with the advent of physically based rendering, I think it is more necessary to have solid foundations about many topics like light, radiometry, etc. That is why I had the need to understand all this theory with the required depth for computer graphics. Given this, I decided to read and understand all these topics from different books, articles, forums, etc, and to try to explain them in an easy and clear way.
I am going to write a series of articles related with lighting, and to try to explain them in an easy and clear way. All suggestions for improvements, corrections, and new topics, are very welcome because in this way I am going to learn a lot and, and why not, maybe this helps anybody with the same doubts than me.
I decided to keep each article not too long to be more concrete in each field to avoid losing the reader. Each article is going to have all the references at the end, so you can learn deeper and better from them.
Next, you can see the list of articles that I will constantly update.
LIGHTING SERIES PART 1 – LIGHT AND RADIOMETRY
LIGHTING SERIES PART 2 – RADIANT ENERGY AND RADIANT POWER
LIGHTING SERIES PART 3 – RADIANCE
LIGHTING SERIES PART 4 – IRRADIANCE AND RADIANT INTENSITY
LIGHTING SERIES PART 5 – PHOTOMETRY
Next post topic is not decided yet.
