I know this is a *really *simple question - so forgive me for asking.. I am
not a programmer but I do want to make Julia the language I use - and move
away from the others that shall not be named.. I would really like an
explicit syntax answer to this:
obj_file = "pathto.obj"
obj = load(obj_file)
display(obj.vertices)
which gives me:
502-element Array{FixedSizeArrays.Point{3,Float32},1}:
Point(0.00117,-0.02631,0.03907)
Point(-0.00896,-0.02466,0.03908)
⋮
Point(-0.01634,-0.0178,-0.05919)
Point(-0.01751,-0.01913,-0.06169)
How do I access this info?
So I can then do a scatter3D plot.
I have tried:
obj.vertices[1,:][1,1]
which gets me this far
FixedSizeArrays.Point{3,Float32}((0.00117f0,-0.02631f0,0.03907f0))
and this
obj.vertices[1,:][1,1][1]
which gets the first value
0.00117f0
But it really doesn't seem that elegant.. which typically means I am doing
something wrong.
I want to put all vertices in a matrix and not look like its a hack.
