Script for creating layered textiles

Post by **louisepb** » Tue Nov 22, 2011 3:55 pm

Hi,

I have just written a script which allows two textiles created using the 2DWeaveWizard to be combined into one textile. This could easily be adapted to have more layers or for the layers to be offset in the x and/or y directions as well as the z direction. Hope it proves useful to some of you.

# Create a 4x4 satin weave with yarn spacing of 1 and thickness of 0.2
weave = CTextileWeave2D(4, 4, 1, 0.2, 1, False)
weave.SetGapSize(0)

# Set the weave pattern
weave.SwapPosition(0, 3)
weave.SwapPosition(1, 2)
weave.SwapPosition(2, 1)
weave.SwapPosition(3, 0 )
# Adjust the yarn widths and heights
weave.SetYarnWidths(0.8 )
weave.SetYarnHeights(0.1)

# Assign the domain and get its limits
weave.AssignDefaultDomain()
Domain = weave.GetDefaultDomain()
Min = XYZ()
Max = XYZ()
Domain.GetBoxLimits( Min, Max )

# Create a new textile to contain the multiple layers
LayeredTextile = CTextile()

# Get the yarns from the first textile and add to the layered textile
Yarns = weave.GetYarns()
for Yarn in Yarns:
LayeredTextile.AddYarn(Yarn)

# Create 2nd textile: Plain weave, spacing of 1 and thickness 0.25
weave1 = CTextileWeave2D(2, 2, 1, 0.25, 1, False)
weave1.SetGapSize(0)
weave1.SetYarnWidths(0.8 )
weave1.SwapPosition(0, 1)
weave1.SwapPosition(1, 0 )
weave1.SetXYarnWidths(0, 1.0 )
weave1.SetXYarnHeights(0, 0.15)
weave1.SetXYarnSpacings(0, 1)
weave1.SetXYarnWidths(1, 0.8 )
weave1.SetXYarnHeights(1, 0.1)
weave1.SetXYarnSpacings(1, 1)
weave1.SetYYarnWidths(0, 0.8 )
weave1.SetYYarnHeights(0, 0.1)
weave1.SetYYarnSpacings(0, 1)
weave1.SetYYarnWidths(1, 1.0 )
weave1.SetYYarnHeights(1, 0.15)
weave1.SetYYarnSpacings(1, 1)

# The yarns will be offset by the height of the first textile
Offset = XYZ(0.0,0.0,0.2)

# Get the yarns from the second textile
Yarns1 = weave1.GetYarns()
# For each yarn in the second textile..
for Yarn1 in Yarns1:
# Get the nodes in the yarn
Nodes = Yarn1.GetMasterNodes()
i = 0
# Offset each node
for Node in Nodes:
Node.SetPosition( Node.GetPosition() - Offset )
Yarn1.ReplaceNode( i, Node )
i += 1
# and add to the layered textile
LayeredTextile.AddYarn(Yarn1)

# Offset the domain to include the second textile
Min -= Offset
NewDomain = CDomainPlanes( Min, Max )
LayeredTextile.AssignDomain( NewDomain )

# Add the textile with the name "LayeredTextile"
AddTextile("LayeredTextile", LayeredTextile)

Some documentation and screenshot of the textile produced can be found in Example 5 on the website here http://texgen.sourceforge.net/index.php ... ate_Models
I may get around to incorporating this into the GUI at some point but it isn't at the top of my to-do list at the moment!
