Practice project for learning about using OpenGL in Qt widget applications. Model loader using Assimp within a Qt widget application.
You can 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
MainWidget::update(), to get textures loading on models look into
material files and see some
examples in the
resources/models/ directory. For more in-depth examples, see
Can be built with cmake manually or using Qt Creator. For the build to be successful, I've found through testing on VMs that the system requires around 6GB of RAM. This is mostly due to the large .obj files that are built into the project using Qt Resource System
This project has been ported to Qt6, which is not yet available in Ubuntu apt repositories.
To run this project, you will need to install Qt6 Open Source Binaries for your system.
Be sure to take note of the Qt6 installation directory, as we will need it to correctly set our
CMAKE_PREFIX_PATH in the next steps.
Once Qt6 is installed, to build and run
qtk on Ubuntu -
sudo apt update -y && sudo apt install freeglut3-dev libassimp-dev cmake build-essential git git clone https://gitlab.com/shaunrd0/qtk && cd qtk mkdir build && cd build cmake .. -DCMAKE_PREFIX_PATH=$HOME/Qt6/6.2.3/gcc_64 && 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.
