I do particular nothing, that is an inherent quality of the general k-means algorithm, since the mean distance to the cluster center is minimized. What I do is that I just say "no more than x" datapoints per cluster and the algorithm creates an approximate solution for it. I create per dataset several cluster instances and do some analysis on the cluster statistics (especially the variance on the size) to decide which cluster-instances are good and which are not, which has a relative balancing effect on the overall quality. If datapoints result in clusters, that are below the lower bound, I mask all datapoints in clusters which are exceeding both bounds and apply the same algorithm on the remaining points and merge the results later on. If I cant even make 2 fitting clusters on the datapoints, I do some sort of brute force solution: sorting the points in terms of distance to the smaller cluster and assigning in ascending distance order until the point swap is even.

So, at the end, I don't know beforehand, how much clusters are "there"; I just have the boundary constraint of the cluster size and I am searching in a recursive fashion and changing focus on datapoints.

Nice to see that you go back to old roots. ^^
The new style is cool. I like it!
Hope to see more from "Razor for my Valentine" in the future.


Today i'am working on .... myself laugh

I already have a skin, but not finished and ready to show.

You didn`t really made this in Med, did you? O_O
It looks pretty detailed and frightning. I`m looking forward to your project laugh
Keep it up! Great work as always laugh .

@HeelX - ahh okay, just the order of pictures was tricky, and I thought the cluster quantity is determined first by item quantity... (which would be also not too complicated, but pre-defining their middle positions by item distribution would be a trouble for me)

@Otter:
Very good optimisation and curves with your low poly dragon laugh
You should post your models on polycount forums !

I must say, I really like this thread, even if I don't post often here. HeelX, thanks for so often providing a bit of background information about the code you use, it's really interesting to read. laugh

Ingame news shown. Players need to know whats up. Additionally, small skits reveal more about the characters, and allow us to tell stories about them. We want the players to grow fond of the characters, but it doesn't fit Dungeon Deities' gameplay, so it's placed in here -- by chosing the TV in the throne room, you can access these stories.

Perhaps this post will get me points for originality at least.

Check out Dungeon Deities! It's amazing and will make you happy, successful and almost certainly more attractive! It might be true!
