Last active December 31, 2015 05:09
Coalescent of the most occurring largest number (in that order of priority.)
coalesce(L, R[n], occurrences = 1):
if L == R[0]:
return coalesce(L, R[1..n], occurrences + 1)
else:
A = coalesce(L, R[1..n], occurrences)
B = coalesce(R[0], R[1..n])
if A occurs more often than B:
return A
else if B occurs more often than A:
return B

Builds a higher (less detailed) LOD of Minecraft style terrain by coalescing the most occurring then most prominent voxels.
typedef struct v3_octree_lod {
unsigned level;
v3_voxel_t voxels[0];
} v3_octree_lod_t;
V3_API void v3_octree_lod_coalesce(
const v3_octree_lod_t *coalesee,
v3_octree_lod_t *coalesed,
const v3_voxel_t *(*select)(const v3_voxel_t *V, const size_t V_n))

It is quite elegant to implement "Shadow Map Allocation" in Butane, if I must say.
settings = {
shadows = {
dynamic = {
atlas = {
dimensions = {
min = [1024, 1024]
max = [4096, 4096]
}
}
}

Second restart results in immediate, catastrophic, wheels-fall-off failure... unfortunately.
