## Testscene

This scene is mostly useful as testbed for your own developments. You should make a copy of the scene folder and modify at will, try material settings or some other details to find out how this plugin behaves. Then build and present your own work!

#### Coordinate and orientation tests

The pillars shown here, as seen from the structure's centre, provide an approximate view (not hi-precision!) to solstice/equinox sunrise/sunset positions in central European latitudes. The central pillars provide an east-west-line. The survey coordinate grid visible on the floor does not align with geographic north. A rotation of -4.2 deg (test for meridian convergence) must be compensated, i.e., while the central pillars must absolutely and always point west-east, the grid lines hit the northern horizon slightly (4.2 deg) left of north!

Walkaround ground coordinates (Ctrl-R, T) should display the coordinates visible along the south and west border of the ground.

#### Material test

This model is also used for testing the plugin's graphical capabilities. You can play with material parameters to create funny effects like semitransparent or glow-in-the-dark brick spheres.

To test temporal features, the pillars and spheres are visible only from the years 2000 until 2020. Edit the material file to change that!
