Starbeamrainbowlabs	a8ddc7831a	wea.table_filter: add API function ... Really, Lua should have this already. At this rate, I'll be implementing the entire Javascript standard library... :P	2021-05-29 23:20:11 +01:00

Starbeamrainbowlabs	38e5c81d33	//subdivide: tally total times so far as we go ... - Don't use wea.sum() on a table full of all the times we've recorded so far - Limit individual stats list lengths to 25 to avoid memory issues when running with a large number of chunks - Tally total times / metrics as we go to avoid memory issues	2021-02-03 03:04:33 +00:00

Starbeamrainbowlabs	fd5804dd9c	//erode: Finish the initial round of bugfixing, but I'm on the fence about it. ... Specifically, I'm unsure about whether I'm happy with the effects of the algorithm. Also, we convolve with a 3x3 gaussian kernel after erosion is complete - and we have verified that the erosion is having an positive effect at "roughening up" a terrain surface. It seems like the initial blog post was correct: the algorithm does tend to make steep surfaces steeper. It also appears that it's more effective on larger areas, and 'gentler' curves. THis might be because the surface normals are more conducive to making the snowballs roll. Finally, we need to decide whether we want to keep the precomputed normals as we have now, or whether we want to dynamically compute them at the some of request.	2020-08-21 20:59:50 +01:00
