Thanks Thomas, that's good to know. Here is my function if anyone is interested, any ideas to make it better will be greatly appreciated.

- Code: Select all
`-- calculate the statistics of a mesh and return a table of those values`

function getMeshStats(verts)

local meshStats = {}

local minX = 0

local maxX = 0

local minY = 0

local maxY = 0

local minZ = 0

local maxZ = 0

local lengthX = 0

local lengthY = 0

local lengthZ = 0

local x, y, z

-- find the bounding box

for k,v in pairs(verts) do

x = v[1]

if x > maxX then maxX = x end

if x < minX then minX = x end

y = v[2]

if y > maxY then maxY = y end

if y < minY then minY = y end

z = v[3]

if z > maxZ then maxZ = z end

if z < minZ then minZ = z end

end

meshStats["min_x"] = minX

meshStats["max_x"] = maxX

meshStats["min_y"] = minY

meshStats["max_y"] = maxY

meshStats["min_z"] = minZ

meshStats["max_z"] = maxZ

-- find the mesh's length for each axis

lengthX = maxX - minX

lengthY = maxY - minY

lengthZ = maxZ - minZ

meshStats["x_len"] = lengthX

meshStats["y_len"] = lengthY

meshStats["z_len"] = lengthZ

-- find the mesh's position

local posX = lengthX/2.0 + minX

local posY = lengthY/2.0 + minY

local posZ = lengthZ/2.0 + minZ

meshStats["pos_x"] = posX

meshStats["pos_y"] = posY

meshStats["pos_z"] = posZ

return meshStats

end

selectedMesh = octane.project.getSelection()[1]

verts = selectedMesh:getAttribute(octane.A_VERTICES)

meshStats = getMeshStats(verts)

print "X info"

print(meshStats["pos_x"])

print(meshStats["min_x"])

print(meshStats["max_x"])

print "Y info"

print(meshStats["pos_y"])

print(meshStats["min_y"])

print(meshStats["max_y"])

print "Z info"

print(meshStats["pos_z"])

print(meshStats["min_z"])

print(meshStats["max_z"])

If you do run the script, just make sure to select a mesh node first. Otherwise it will not work.
