Qtk

Practice project for learning about using OpenGL in Qt5 widget applications. Model loader using Assimp.

You can fly around and see the examples I made, or import your own models within mainwdget.cpp, inside the MainWidget::initObjects() function. I've commented throughout the code there to explain which model or example I'm modifying. Rotations and translations happen in MainWidget::update(), to get textures loading on models look into material files and see some examples in the resources/models/ directory.

Can be built with cmake manually or using Qt Creator.

To build and run qtk on Ubuntu -

# Qt Creator
sudo apt update -y && sudo apt install qttools5-dev freeglut3-dev libassimp-dev
git clone https://gitlab.com/shaunrd0/qtk
mkdir build && cd build
cmake .. && cmake --build
./qtk

You can fly around the scene if you hold the right mouse button and use WASD. If you see a small triangle floating by a model it represents the light source that is being used for the shader rendering the model. These appear on models using phong, specular, and diffuse lighting techniques.
