Mesh Data Gather 1.0.0 for Maya (maya plugin)

Plugin add couple commands to Maya for reading mesh data more easily what you can do with native script commands.

List of new commands.

• double[] GetVertex(String meshName, int vertexIndex)
  Return mesh vertex as float array [x, y, z] in object space.
• int[] GetFace(String meshName, int faceIndex)
  Return mesh faces as int list [A, B, C, ..., ...].
• float[] GetUV(String meshName, int faceID, int faceVertexID, string uvSetName)
  Return UV coordinate as float array[U,V]
• double[] GetVertexNormal(String meshName, int vertexIndex)
  Return mesh vertex normal as float array [x, y, z] in object space.
• double[] GetFaceNormal(String meshName, int vertexIndex)
  Return mesh face normal as float array [x, y, z] in object space.

It's easy to use. Just load a plugin via PluginManager or via script. Here's example for Python.

Example 1 - Python Mesh Exporter

import maya.cmds as cmds
cmds.loadPlugin("MeshDataGather.mll")
 
meshesList = cmds.ls ( geometry=True )
for mesh in meshesList:
    print "Get data from mesh " + mesh
    print "Vertex data"
    for i in range(0, cmds.polyEvaluate(v=True)):
        v = cmds.GetVertex(mesh, i)
        print v
    print "Face data"
    for i in range(0, cmds.polyEvaluate(f=True)):
        f = cmds.GetFace(mesh, i)
        print f
    print "UV data"
    for i in range(0, cmds.polyEvaluate(f=True)):
        for j in range(0,3):
            uv = cmds.GetUV(mesh, i, j, "uvSet1")
            print uv
    print "Vertex normal data"
    for i in range(0, cmds.polyEvaluate(v=True)):
        n = cmds.GetVertexNormal(mesh, i)
        print n
    print "Face normal data"
    for i in range(0, cmds.polyEvaluate(f=True)):
        n = cmds.GetFaceNormal(mesh, i)
        print n
cmds.unloadPlugin("MeshDataGather.mll")
