Hello, I am trying to populate a TIN 3D surface with components. Within each triangle surface I would like two random components( represented by different colored dots in attached picture). Does anyone have any idea of how to populate the TIN more quickly than placing every component by hand. The TIN was imported into sketchup from ArcGIS.
I produced this results[image: BnjL_DotsonFace.jpg]
with this code
def placethedots
mod = Sketchup.active_model
ent = mod.active_entities
sel = mod.selection
cdefs = mod.definitions.reject{|cd| cd.group?||cd.image?}
faces = sel.grep(Sketchup;;Face)
faces.each{|f|
tx=0.0;ty=0.0;tz=0.0;
p=f.outer_loop.vertices.collect{|v|v.position}
p.each{|v| tx+=v.x;ty+=v.y;tz+=v.z}
ax=tx/p.length;ay=ty/p.length;az=tz/p.length
ctr=Geom;;Point3d.new(ax,ay,az);#ent.add_cpoint(c)
pt1=ctr.offset([-6,6,0])
cd=cdefs[rand(cdefs.length)]
ent.add_instance(cd,Geom;;Transformation.new(pt1,f.normal))
pt2=ctr.offset([6,-6,0])
cd=cdefs[rand(cdefs.length)]
ent.add_instance(cd,Geom;;Transformation.new(pt2,f.normal))
}
end
I first created the six component "dots". Selected the faces then executed the code.
