Fixed Function to Modern OpenGL (Part 4 of 4)

The code referenced in this blog is available here. Texturing Texture setup in modern OpenGL is nearly equivalent to what you are used to in the fixed-function API.  You still have to enable your texture units, create and configure your texture objects (including mipmap chains), upload…

Fixed Function to Modern OpenGL (Part 3 of 4)

The code referenced in this blog is available here. In our last blog, we re-implemented the famous OpenGL triangle in world space and compared and contrasted the fixed-function GLUT program with an equivalent Modern OpenGL program.  We covered how to use Qt's math functions to…

Fixed Function to Modern OpenGL (Part 2 of 4)

The code referenced in this blog is available here. This is the second of a four part blog series, in which we compare and contrast Fixed-Function OpenGL with Modern OpenGL and introduce you to the issues involved in porting your code to Modern OpenGL. Last time we covered the necessary steps you…

Fixed Function to Modern OpenGL (Part 1 of 4)

The code referenced in this blog is available here. In this first of a four part blog series, we outline differences between Fixed-Function OpenGL with Modern OpenGL and show effective solutions for common issues encountered when porting your code to Modern OpenGL. I was once faced with the task…

An Introduction to Qt3D

In this blog post, we'll take a brief look at one of the newest Qt modules, Qt3D, which was introduced in Qt 5.5.0. What is Qt3D? Qt3D is a new Qt module that provides support for 2D and 3D rendering. It also provides a generic framework for supporting simulations that go beyond just rendering,…

Qt and OpenGL: Loading a 3D Model with Open Asset Import Library (Assimp)

This blog post is the first in a series that will cover using OpenGL with Qt. In this installment, we will look at how to use Open Asset Import Library (Assimp) (1) to load 3D models from some common 3D model formats. The example code requires Assimp version 3.0. The code also uses Qt for…
