3D Virtual Visit
The application provided is a 3D engine with highly detailed models for Ponte de Lima with both the XIV century and XXI century versions. With the application you can walkthrough Ponte de Lima in realtime.
The application uses Vertex Buffer Objects, hence it requires OpenGL 1.5. The XXI century version is particularly demanding in graphics terms due to high level of detail of the models and the number of textures used.
In case you are having problems we suggest checking for a driver's update.
