Hi,Is it possible to recursively offset a curve on a sphere without scripting?The offset distance is a function of the previous offset distance. I am trying to make a latitude-longitude grid on a sphereAny help would be appreciated.Anne See More

Hi all,This might be more of a mathematical question than a GH-technique question, but I'll try anyway:I would like to construct a latitude-longitude-grid on a sphere. [As I understand it, unlike the default mesh on a sphere in Rhino/Grasshopper], the lat-lon-grid has quasi-uniform grid spacing, so that every given rectangle on the grid approximates a square. The approximated squares gets infinitely small at the poles, but continues to be approximated squares rather than rectangles. In my…See More

Hi, I am new to GH, so this is a very simple question:I am trying to create a surface which is tangent to a sphere on a givenpoint. I have succeeded in creating a plane like that, but when turningthe plane into a surface, it is automatically placed with its corner -rather than center - coinciding with the point on the surface. Is there a smart way of changing that - or a better way of making tangent planes all together?Thanks,Anne See More
