Problem with Seam line overlap in Bump Tiling Nurb

Hey guys I am very new to grasshopper, and even newer to this forum. Was wondering if anyone had ever had a similar issue to overcome.

Im working with a bump tiling map on a sphere and cant manage to remove the seam line and overlap. I have tried to remove the excess points and merge points to no avail. I want to merge the surface so it is continuous around the whole sphere.

Any help would be greatly appreciated.

Fist things first:

your goal is to distort something (in this occasion a sphere but wait for the trad update V2, he he) based on one (or many: V2) attractors THAT influence a variable amount of control points ... and then so some tiling with the distorted thingy?

If yes ... see this attached

PS: there's a vast variety of ways to distort via cntrPoints (or not).

Found a couple of minutes to elaborate further on this.

Here comes the pain (Note: load Rhino file first):

Added 2 mode tests to indicate the main point here. First > use the flat surface AND don't switch to the other cases until you get the gist of the available options (push/pull, reverse, 2 surface creation modes, distance values remap etc etc).

Push/Pull:

The main point here:

In plain English: a capability is added to exclude "peripheral" control points from the sample of modified points > toggle this bool in pink (shown: the false option) to get the gist of it and think: a sphere (or any closed in U/V surface) is in fact a "rolled"/"wrapped" variation of that flat thingy. Imagine what happens if you attempt to modify the sphere "star" points ...

I hear you: but ... you start (gradually) replacing components with these C# freaky things of yours > is this help? Well ... er... can I have the next question please? he, he.

Next update (V4): 10+ "tiling" options (patterns) for that poor surface. Plus random/chaotic stuff. Plus 12,34 divisions by zero

have fun, best, Peter
