P-152: Virtual World Concept Update 19: Spherical Terrain: Seamless Seams!

I spent all of this week working on the seams between the planes.

The first challenge was to select the correct vertices. I wanted to select the rows of vertices around the borders of the plane, and not the vertices in the middle. I eventually managed to do this.

The second challenge was to access the height data from multiple planes simultaneously. so that I can perform linear interpolation. This was also difficult, and I had to make changes to the terrain rendering algorithm to do this.

The challenge that I am still stuck on is to actually connect the seam faces together.I have managed to draw a roughly straight plane from one seam to the next, and I am now trying to add a curve to that plane to smooth the two seams.

I knew before I started this project that this would be the most difficult part of it. I am uncertain as to whether I can actually figure this out. I have a few more ideas that I can try, but smoothly interpolation between the seaming values is very complex.
