Dear @xjy11, thank you for providing this example. As you see in the output, HELIOS++ tries to replicate the *position* and *attitute* of the input trajectory as close as possible....

**Addition** In addition to (t, x, y, z) typical trajectory files also have roll, pitch and yaw angles. The order can be different, depending on the system vendor, and should...

**Subset of given trajectory** To separate individual flight strips, it would be good to have the option to define a filter when loading the trajectory. Usage example (`tStart` and `tEnd`...

Hi @xjy11, you can edit the python code to write other values into the `Return Point Wave Location` field: https://github.com/3dgeo-heidelberg/helios/blob/da206462676a47bab568ba73d4ea8d8c93822694/pyhelios/util/txt2las_wdp.py#L41-L42 The LAS Standard states: > The temporal offset in picoseconds...

Hi @xjy11, thank you for your patience. While the fullwave output of HELIOS++ does not contain the exact point in time attributed to each point, it can easily be calculated...

I see that there is a numRays property here: https://github.com/3dgeo-heidelberg/helios/blob/a122d6d7e8cafa70781681e7d8f895dff9add439/src/pybinds/PyHelios.cpp#L439 However, setting the number of rays directly should not be supported. Instead, the beamSampleQuality should be set, and the number...

Some python code how to solve for the turning points is included here: [oscillating.zip](https://github.com/3dgeo-heidelberg/helios/files/6494213/oscillating.zip) Results look like this:   Note the name of variables used in the script: 

@albertoesmp thanks for implementing this. It seems like something is wrong with the parsing of the date when given as `YYY-MM-DD hh:mm:ss`:  Here, I calculated the unix timestamp with...

"i.e, the strips can be not consecutive without problem (leg000 -> strip000, leg001 -> strip001, leg002 -> strip000, etc)." so this means arbitrary combinations are allowed, and the files are...

Hi @AJAY31797 , thanks for your questions. 1. the x-axis is pointing towards the right wing (i.e., the positive y-axis is pointing forward). This is a so-called RIGHT-FORWARD-UP (RFU) definition...
