Scatter building points
- init attributes: N, up, scale, floor count
- point distribution
- scatter node: relax itterations
- point relax node: relaxing per pscale and conforming the points to geo in the 2nd input
- measure: removing points per slope angle
- vex/vop: nearpoint, pcopen
Template box copying / shaping
- name template box. floor, ceiling, north, south, etc.
- copy template box to floor level
- rbd intersect / detangle hda
- stack boxes based on floor level
- feedback loop, isolate ceiling, make centroid
- set initial attributes, orient, floor level, size of next box
- copy new floor box
- shaping
- taper based on floor levels
- isolate % of corners -> scatter box -> bool subtract
- twist, bend floor levels
- conform / fit building angle to each other and ground
- insets, cutting out portions for more interesting shapes
- postifx your template box naming scheme, east_inset, west_inset
- bool subtract the shapesand the new walls will inherit the new name
Naming convention
- s@type -> building number, build1, build2, etc
- s@type_prop -> door, lamps, ceiling, wall, etc
- i@type_id, i@type_itt
- s@type_mat -> obsolete with usd
- i@level, i@level_max -> floor level
- i@lod -> level of detail
- i@cluster -> wedging number
Rotation around an axis
Template box labels
- facet -> unique points , post-compute normals
- fuse points, set rest position, normals
- copy to src points
Rotation around an axis
// point wrangle
v@up = @N;
matrix3 m = maketransform(v@dir, v@N);
vector axis = v@up;
@angle = radians(fit01(rand(@build_id),ch('min'),ch('max')));
rotate(m, @angle, axis);
p@orient = quaternion(m);Template box labels
- facet -> unique points , post-compute normals
- fuse points, set rest position, normals
- copy to src points
// prim wrangle
int pts[] = primpoints(0, @primnum);
vector normal = point(0, "N", pts[0]);
if (normal.y > 0)s@type = "roof";
else if (normal.y < 0)s@type='floor';
if(normal.y==0)s@type='wall';
if(@type=='wall' && normal.x==1 || normal.x==-1)@type='wall_x';
if(@type=='wall' && normal.z==1 || normal.z==-1)@type='wall_z';
detangle intersecting
- bullet solver deintersect hda
- used it quite allot so i packaged it up, but basically its just setting found_overlap on your packed geometry

bricker
- cutter tool that aligns itself to the longest edge of a poly. useful for brick walls, rooftops, upres messy topology etc.
- cut rows and or columns, group every second row

window hda
- create a couple of window variants for your "copy to points" node
- output: packed geo (window, pane, sub), lod toggle
2020-09-20
electrical box
- min, max parms on all attribs, seed slider creates new variantes
- input for external cables feeding into the box

door hda
- which will be the first and last door i will ever model
- same logic as the window hda
