pymel.core.modeling.polyProjection¶

polyProjection(*args, **kwargs)¶

Creates a mapping on the selected polygonal faces. When construction history is created, the name of the new node is returned. In other cases, the command returns nothing.

Flags:

Long Name / Short Name		Argument Types	Properties
constructionHistory / ch		bool
	Turn the construction history on or off (where applicable).
createNewMap / cm		bool
	Create new map if it does not exist.
imageCenterX / icx		float
	Specifies the X (U) translation of the projected UVs. Default is 0.5.
imageCenterY / icy		float
	Specifies the Y (V) translation of the projected UVs. Default is 0.5.
imageScaleU / isu		float
	Specifies the U scale factor of the projected UVs. Default is 1.
imageScaleV / isv		float
	Specifies the V scale factor of the projected UVs. Default is 1.
insertBeforeDeformers / ibd		bool
	Specifies if the projection node should be inserted before or after deformer nodes already applied to the shape. Inserting the projection after the deformer leads to texture swimming during animation and is most often undesirable. Default is on.
keepImageRatio / kir		bool
	Specifies if the xy scaling in the planar projection has to be uniform. By setting this flag, the texture aspect ratio is preserved. This flag is ignored for cylindrical and spherical projections.
mapDirection / md		unicode
	Specifies the direction of the projection. By specifying this flag, the projection placement values (pcx, pcy, pcz, rx, ry, rz, psu, psv) are internally computed. If both this flag and the projection values are specified, the projection values are ignored. Valid Values are : X Projects along the X Axis Y Projects along the Y Axis Z Projects along the Z Axis bestPlane Projects on the best plane fitting the object camera Projects along the viewing direction perspective Creates perspective projection if current camera is perspective Default is bestPlane.
projectionCenterX / pcx		float
	Specifies the X coordinate of the center of the projection manipulator.
projectionCenterY / pcy		float
	Specifies the Y coordinate of the center of the projection manipulator.
projectionCenterZ / pcz		float
	Specifies the Z coordinate of the center of the projection manipulator.
projectionScaleU / psu		float
	Specifies the U scale component of the projection manipulator.
projectionScaleV / psv		float
	Specifies the V scale component of the projection manipulator.
rotateX / rx		float
	Specifies the X-axis rotation of the projection manipulator.
rotateY / ry		float
	Specifies the Y-axis rotation of the projection manipulator.
rotateZ / rz		float
	Specifies the Z-axis rotation of the projection manipulator.
rotationAngle / ra		float
	Specifies the rotation of the projected UVs in the UV space. Default is 0.
seamCorrect / sc		bool
	Specifies if seam correction has to be done for spherical and cylindrical projections. This flag is ignored, if the planar projection is specified.
smartFit / sf		bool
	Specifies if the projection manipulator has to be placed fitting the object. Used for cylindrical and spherical projections. For smart fitting the planar projection, the mapDirection flag has to be used, since there are several options for smart fitting a planar projection.
type / t		unicode
	Specify the type of mapping to be performed. Valid values for the STRING are planarcylindricalsphericalDefault is planar.
uvSetName / uvs		unicode
	Specifies name of the uv set to work on. Flag can have multiple arguments, passed either as a tuple or a list.

Example:

import pymel.core as pm

pm.file( f=True, new=True )
# To create a planar projection
#
pm.polyPlane( sx=10, sy=10 )
pm.move( 0, 0, r=3 )
pm.polyProjection( 'pPlane1.f[0:99]', type='Planar', md='y' )
polyPlanarProj1
# To create a cylindrical projection
#
pm.polyCylinder()
pm.polyProjection( 'pCylinder1.f[0:21]', type='Cylindrical' )
polyCylProj1
# To create a spherical projection
#
pm.polySphere()
pm.move( 0, 0, r=-3 )
pm.polyProjection( 'pSphere1.f[0:399]', type='Spherical' )
