[julia-users] Using PyPlot to work with obj files, noob question on arrays

[kleinsplash]

Hi,

I want to just load a mesh and plot it along with a bunch of other data on 
one plot. Just simple plotting. I have a way that's working but it's just 
wrong: 


mesh = load(obj)

#mesh = HomogenousMesh(normals: 420xGeometryTypes.Normal{3,Float32},     
vertices: 420xFixedSizeArrays.Point{3,Float32},     faces: 
840xGeometryTypes.Face{3,UInt32,-1}, )
#typeof(mesh) = 
GeometryTypes.HomogenousMesh{FixedSizeArrays.Point{3,Float32},GeometryTypes.Face{3,UInt32,-1},GeometryTypes.Normal{3,Float32},Void,Void,Void,Void}

# inefficient way of finding the number
x=0
for v in mesh.vertices
    x+=1
end 
# set up array with verticies 
vert = Array{Float32}(x,3)
# map to new array 
for i = 1:x
    vert[i,:] = [mesh.vertices[i][1], mesh.vertices[i][2], mesh.vertices[i][
3]]
end 
#plot with PyPlot
plot_wireframe(vert[:,1], vert[:,2], vert[:,3])

length(mesh.verticies) doesn't work, and I haven't figured out how to 
instantiate an empty Array without having the dimensions. 


Any help would be much appreciated. 

Thx
