AL ModelUtility / HDALC - Houdini Indie 18.5+
A pack of HDALC (houdini indie / apprentice tools) helping on procedural modeling. Extensively using those on NeoGothic/Victorian architecture project.
I will add some more as I am going through my old scenes and cleaning things up.
AL_topbottom :
Blast, Isolate or create Groupe based on faces pointing up or down.
AL_centertogrid :
Center any geo back to the origin of world. Can fit geo on top, bellow or in center of the grid.
AL_mixinput :
Mix two geo plugged in input1 and input2 (must have same amount of points) either based on Bbox mask or custom attribute.
AL_ID_generator :
Create an ID attribute (float or vector) based on connectivity.
AL_delete_from_distance :
Delete points closer to the object plugged in second input.
AL_extract_centers :
Extract points/center of primitives. Either individual faces or by pieces.
AL_extract_grid :
Extract a grid on top, middle or center of input geometry.
AL_extract_corners :
Turn a face into a more complex geo. Ideal as a base to generate towers.
AL_group_by_object :
Group primitives contained by object plugged in second input.
AL_measure_height :
Store a "height" detail attribute. Measure dimensions of an object in X, Y or Z.
AL_middle_point :
Extract middle points of every edges.
AL_simpleborder :
Group unshared edges and dissolve the rest. Ideal to create profil geo for sweep operations.
AL_extrude_points :
Extrude one or several points.
