Creating a planet grid with Splines (LONGITUDE & LATITUDE) for a planet like the earth


#1

Hi Folks,

i try to create a spline-based grid for a planet with separate splines for the longitude and latitude.
Can you help me with that? Its no problem to create the LONGITUDE with a cloner and a arc spline. But is is much more complicated for the LATITUDE:


#2
  • Create a sphere
  • Make it editable,
  • Select the edge loops you want (longitude or latitude)
  • Go to Menu / spline / conversion / edge to spline.

If you need to use effectors on them later, put them in a fracture object.

There is a problem and a reaseon I am looking for a different approach. Spheres can only devided in segments equally for example 32 in each direction. Since I am going for a different setting I could use your method on 2 different spheres, butt I am pretty sure there is a more elegant way to create a sphere meridian rig…

GeLoSy 1.3

Besides the geo location stuff GeLoSy gives you a globe rig with all the geographic lines.
LAT, LON in degree steps from 5° to 90°.
Converting the GeLoSy object gives you the sweep hierarchy.

You can do it with iteration and some trig

With a suitable array of straight splines and the Wrap deformer, it’s pretty straight forward. See the attached file.

Thank you jedi. Well done. This is what I was looking for…

Thank you PCOOMBES! Amazing. You even animated the splines… The Wrap deformer is an interesting and very smart solution… GREAT! Thanks again!
