I have managed to fix this issue.<\/p>\n

It was not caused by the issue that I was concerned about, but it was somewhat related. The problem was actually due to the noise scale being applied to the higher tiers of the terrain. A planet should appear almost perfectly round at long distances, but I had, for some reason, set a very strong noise level on the upper tiers, which meant that the planet looked more like an asteroid, with visible pits and extrusions.<\/p>\n

When I changed the noise level to a more realistic scale, the problem I was seeing at the lower tiers disappeared. The issue now is that reducing the noise scale at the upper tiers has made the terrain very barren and featureless. This is tolerable for now, and hopefully when I add shape and foliage replicators it won’t look so obvious, but this will need to be dealt with in the future. I can leave that until I replace conventional perlin noise with simplex noise, probably in MS3.<\/p>\n

This will also help to solve the issue I was having with the gravity vector. I was trying to adjust the vector to point towards the world center (64-bit) rather than the terrain object center (32-bit) but I was having issues with the vector. These issues are quite likely to have been caused by this problem, and I should now be able to correct the gravity vector. There is a chance that this issue is also responsible for some of the problems I had re-implementing the Field of View optimisations, although this is unlikely.<\/p>\n

The only issues left in MS2 now are fixing the gravity vector, attempting to implement the FOV optimisations, implementing a simple groundcover\/shape replicator demonstration, and final debugging and testing.<\/p>\n

These images show the deviation that I was talking about:<\/p>\n

I then spent some time adjusting the noise scale, resulting in some strange issues:<\/p>\n

This is the current state of the terrain, but it is subject to change. I realise that there is very little definition, but the final look of the terrain is in need of improvement. The main goal at this point is proof of concept for the larger, more complex issues, such as the LOD’s and planetary scale.<\/p>\n
