Maya (.ma)

Autodesk Maya scene description format.
3D geometry format.
Native format of the Maya modeling, animation and rendering software.
Used for storage and interchange of 3D graphical objects.
ASCII format.
Can store multiple 3D objects as polygon primitives.
  • Export supports Maya 4.0 ASCII files.
  • Export["file.ma", expr, elem] creates a binary Maya file by treating expr as specifying element elem.
  • Export["file.ma", {expr1, expr2, ...}, {{elem1, elem2, ...}}] treats each expri as specifying the corresponding elemi.
  • Export["file.ma", expr, opt1->val1, ...] exports expr with the specified option elements taken to have the specified values.
  • Export["file.ma", {elem1->expr1, elem2->expr2, ...}, "Rules"] uses rules to specify the elements to be exported.
  • See the reference pages for full general information on Export.
  • General element:
"Rules"full list of rules for each element and option
  • Data representation elements:
"Graphics3D"Maya file represented as a Graphics3D object
"GraphicsComplex"list of GraphicsComplex objects, each representing a 3D geometry stored in the file
"PolygonData"the polygon elements in indexed form
"PolygonObjects"list of Polygon primitives given in absolute coordinates
"VertexData"list of vertex coordinates
  • The "VertexData" element corresponds to the first argument of GraphicsComplex.
  • Advanced option:
"VerticalAxis"{0,0,1}orientation to assume for the coordinate system used in the file
  • By default, Mathematica assumes that in the coordinate system used by Maya the vertical axis corresponds to the third coordinate.
  • With the setting "VerticalAxis"->{0, 1, 0}, Mathematica will apply the transformation {x, y, z}->{x, z, -y} to all graphics coordinates when exporting to Maya.
