Hi guys, my first post on the new Forum, and to be honest I never really did much in the old! I have very limited knowledge of Grasshopper however I’m pretty decent in Rhino. I am by trade an architectural visualiser, and recently have been working with a Drone company that specialise in aerial video footage.
Recently i was given the flight data from the drone, which captures huge amounts of info regarding it’s location, about the gimbals for the camera, etc…
My end game is to generate a flight path accurate to that of the drone it self in 3d, I will end up exporting to 3dmax where I can add my camera to a spline and then camera match up with 3D geometry to superimpose over footage. I tried to reverse engineer and just track footage in after effects and export that to Max however it felt very inaccurate, even it’s best guess is still a guess!
SOOO to cut long story short I have managed to work out how to extract data from an excel sheet, and convert Lat / Lon into meters thanks to some great references ( https://www.grasshopper3d.com/forum/topics/tricky1-latitude-longitudinal-co-ordinate-points-into-points for instance by [Danny Boyes]).
considering i haven’t really done much with Grasshopper I impressed my self that I could get it to work this far!
So right now I have plenty of points following the path of this drone, before I continue I wanted to know if I was doing this the right way and most efficient way, as there are over 10k worth of data points and it takes some time to process!
Originally I had the Multiply plugged right in to the Eval, however I wasn’t sure if each time i was updating the whole thing it also ran the full number of info fields through the Eval too just for a * equation. so I pulled the top number and used this instead. my question is would this help performance or keep it the same?
This is just one of many questions I will probably end up asking however I thought it would be useful for anyone to reference me on this fact finding journey!
Once I get this done I aim to also get a gimbal path also set up so I could potentially set up a “target” for my camera to also follow… then who knows maybe even get the whole thing to run off of time it self!!!
Mmmmm giving the path a quick measure it’s also not right, generally the path looks similarish to a googlemaps .KML format given to me however it’s warped slightly and longer! so something in terms of formula perhaps is not right for me? mmm what have I done wrong :S
How do i get gimbal information and turn it into an animated moving object based on the flight info? I have time as a recording also so that means I could accurately show the gimbal at different positions to the exact time!..
