Hello everyone,

i'm trying to acomplish airplanes route animation and stuck at connecting two points with spline.

1. I parsed data from orouostai.cvs
_<_t_>_ -17.3542 | , | -145.4961 | , | AER

31.0733 , 33.8358 , KZN
36.8222 , 7.8094 , OVB
29.7275 , -85.0274 , CEK _
import c4d
import csv
import re
  
filepath = r'D:\Grafikos Dizainas\Projects\LRT\Plazmos grafika\JM\C4D\python\data\orouostai.csv'
scale = 10
  
def GetData(source) :
    data = list()
    
    with open(source, 'r') as csvdata:
        dataset = csv.reader(csvdata, delimiter=',')
        for row in dataset:
            
            pattern = re.compile("[A-Z]{3}|[A-Z]{1}[0-9]{2}")
            search = pattern.search(row[-1])
            abbr = search.group(0)
            
            data.append('%s, %s, %s' % (abbr, row[0], row[1]))
    
    csvdata.close()
    data.sort()
    return data
  
def DrawData(source) :
    container = c4d.BaseObject(c4d.Opolygon)
    container.ResizeObject(len(source), 1)
    
    for i in range(0, len(source)) :
        row = source[i].split(',')
        x = float(row[1]) * scale
        y = float(row[2]) * scale
        
        container.SetPoint(i, c4d.Vector(x, 0, y))
        
    doc.InsertObject(container, None, None)
    container.Message(c4d.MSG_UPDATE)
    c4d.EventAdd()
    
DrawData( GetData(filepath) )

i got all points in place, but how join whem with curved spline by airport name from another cvs file marsrutai.cvs

_p> AER ' KZN
ASF ' KZN
ASF ' MRV
CEK ' KZN
CEK ' OVB_

Hello and welcome,

what exactly is your question? Do you want to create a SplineObject?

Best wishes,
Sebastian

I want to join airport point with curved spline. i want to create something like this https://vimeo.com/88093956 creating spline lines, use splines as paths and move particles with tracer. But i don't know how to get values from marsrutai.csv and search it in orouostai.csv to get coordinates (longtitude latitude). for example.

In orouostai.csv i have all my airports short names and coordinates. In marsrutai.csv i have all flight routes with airports shortnames.

orouostai.csv ->
(airport shortname) AAA, 54.687156, 25.279651 (coordinates)

marsrutai.csv ->
(origin) AAA - BBB (destination)

Sincerely, D.

If I get you correctly, you already have all airports in the scene, right?
Now all you need is to connect them, am I correct?

In this case, let's say, you have 2 null objects in the scene: 1 - AER and 2 - KZN airports. Both these nulls are named exactly as you have them in marsrutai.csv.

So, logical way to do next is to parse marsrutai.csv, and get 2 airports (AER and KZN). Then do search in Object Manager to find these airports, get those coordinates, and draw a Spline Object.

Yes, No, Yes?? I this that should work.

Sveikas atvykes i ekspertu foruma:) (welcome to the forum)

I have one polygon object with all airport points in it. Or i nees to create all 6k null objects to join them?

Sveikas, nesitikėjau lietuvį susitikti čia :)) labai smagu!

This does not have to be null objects. I just used them for example, as it's easier for me to depict what's going on in the scene.

Does your airpots are represented as a vertex point or a polygon? In both cases, just look up for that particular vertex or polygon ID and match it to your airpot.

P.S. We can discuss this eye to eye:) just call me. My contacts are on my page.
