PostgreSQL - Setting up - Linux Ubuntu

PostgreSQL is one of the most known and used SQL server.

We’re going to see how to install it on a Linux opearting system, to be precise on Linux Ubuntu.

C++ - NVIDIA CUDA - Using the compute_xy and sm_xy compile options to generate an executable

To use an NVIDIA GPU (the graphic card processor) you need a CUDA driver.

And if you want to compile a program for a GPU you'll have to use the CUDA toolkit.

C++ - Qt Framework - Mixing native OpenGL functions with Qt ones

Having the Qt Framework as GUI for OpenGL can be helpful of course but sometimes it seems easier to use the native OpenGL functions directly.

This is exactly what we are going to see in this tutorial by mixing Qt and native OpenGL functions.

C++ - Qt Framework - Using QOpenGLWidget to display a shape with lighting and normal vectors

Lighting is certainly one of the most interesting effect that we can make with OpenGL.

Combined with colors and normal vectors, lighting becomes visually realistic.

C++ - OpenCV - Hello world

In a previous tutorial we set up OpenCV with Visual Studio.

This time we are going to make our first Hello world OpenCV project.

Let's see that.

C++ - OpenCV - Setting up with Visual Studio

OpenCV is an interesting library aimed to computer vision.

But before playing with it, it's necessary to set up your IDE.

This IDE will be Visual Studio for this tutorial.

So let's get started.

C++ - Qt Framework - Using QOpenGLWidget to display a window for moving shapes with keyboard and mouse

In the past tutorials about Qt and OpenGL we saw how to deal with some basic tasks.

Let's see this time something a bit more advanced with the QOpenGLWidget class in order to display a scene from a window with a shape.

C++ - Qt Framework - Using OpenGL texture with index array

 Playing with colors can be fun but what about textures?

What about something really realistic?

In this OpenGL tutorial for Qt we are going to apply a texture on our dear triangles.

C++ - Qt Framework - Using OpenGL VAO and VBO to handle 2 different objects on the scene

VAO (Vertex Array Object) and VBO (Vertex Buffer Object) were introduced to help programmers since OpenGL 3.0.

So it’s not a recent features but if you just started learning OpenGL it could be very complex to understand.
