Geomipmapping: How to remove the gaps?

Structural · 2003-02-04T10:19:06

I have a relatively simple heightmap at the moment, loaded from a raw file. I split it up in a quadtree and applied some geomipmapping in a bunch of vertex arrays. I''ve got my first geomipmapping going, but between the terrain patches the are gaps, because when the detail is lowered the vertices do not align properly anymore. How can I solve this? Should I lower the mipmapping steps (which is a multiplication of two at the moment) or are there other methods that solve this? Thank you!

It was my fault, I moved the wrong indices to the wrong place when I lowered the LOD on one side of the patch.

Anyway, I have solved half of the algorithm to change the indices, but I am stuck on the last two sides, where I have to get the indices on the top and the bottom (I render from left to right, and then up and down and up and down etc etc). The right and left part of the patches align perfectly now.
