I am making avery general question.
I download ArtoolKIt from this link (Software y Extras) ArtoolKit and I use this command in terminal in ubuntu:
apt-get install freeglut3-dev libgl1-mesa-dev libglu1-mesa-dev
libxi-dev libxmu-dev libjpeg-dev
And then ./Configure and $make.
So after these I have some simple Augmented Reality projects inside bin folder that can be executed. The problem is I cannot find where to modify these simple projects. LIke they are prepared for execution but I cannot find their code to make modifications.
Has somebody experienced this?
I recommend to get the sources and everything from this repository https://github.com/artoolkitx/artoolkit5 as it holds the most recent changes to ARToolKit. The link you shared is not working for me so I cannot verify the package you got. You can get the building on Linux information from here https://github.com/artoolkitx/artoolkit5/wiki/Building-on-Linux
All the code for the examples is available in the examples directory inside the repository: https://github.com/artoolkitx/artoolkit5/tree/master/examples
I recommend to start with [simpleLite] (https://github.com/artoolkitx/artoolkit5/tree/master/examples/simpleLite)
As it is the easiest place to start, from my point of view.
Let me know how it goes.
