The matrix_world of the camera in Blender is column-major ordered and not row-ordered as in python
Thus the tranpose is given as matrix_world

Edit the tunnel of sridhar, so that we can render what the bee sees

Added function to load trajectory from csv file
Added one environment (Sridhars tunnel) and one trajectory to test overlaying
Added tables in requirement (anticipation for hdf file)

to overlay a trajectory in a blender environment (in order to debug misaligment between world and trajectory
to render images along a trajectory

A command line can be used to create grid based database

Added Trajectory tools to load from dataframe
Change database a bit so to return a Trajectory whenever possible (i.e. unique convention)
Clean a bit the code in dataframe to check user validity. Code was redundant

So that grid and trajectory rendering can be performed seemlessly
The test fucntion does not run yet

These files have been used for a presentation
They will be place in a tutorial or default like function to faciliate running model on world

Help to work with pandas multiindex dataframe
Will support lollipop plots

This feature will be useful for easy trajectory rendering

changing for new convention, this is a temporary push that contains still contains mistakes, just for backup

added database 2 for conventions in posorient, changed database and database tests accordingly and database

Rename test file for clarity

Clean test function of blender, so to remove unnessesray lines

The position orientation of the camera in the environment is directly set
This allow us to use our homogeneous transformation function, and do not rely on blender conventions

Add test from one convention to another convention

commented test, changed the range for elevation and azimuth and added check that max difference is samller 2pi;
