Working with Cylinder

Customize Offset Top

Aspose.3D for Python via .NET allows customizing Offset Top of a cylinder. In order to use this functionality, you can use offset property of Cylinder class. The following code snippet shows how to customize Offset Top:

from aspose.threed import FileFormat, Scene
from aspose.threed.entities import Cylinder
from aspose.threed.utilities import Vector3

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  Create a scene
scene = Scene()
#  Initialize cylinder
cylinder1 = Cylinder(2, 2, 10, 20, 1, False)
#  Set OffsetTop
cylinder1.offset_top = Vector3(5, 3, 0)
#  Create ChildNode
scene.root_node.create_child_node(cylinder1).transform.translation = Vector3(10, 0, 0)
#  Intialze second cylinder without customized OffsetTop
cylinder2 = Cylinder(2, 2, 10, 20, 1, False)
#  Create ChildNode
scene.root_node.create_child_node(cylinder2)
#  Save
scene.save("data-dir" + "CustomizedOffsetTopCylinder.obj", FileFormat.WAVEFRONT_OBJ)

The left one has offset_top set to (5, 3, 0), it’s easy to see the top cap has moved and the whole torso also gets affected.

Customize ShearBottom

Aspose.3D for Python via .NET allows customizing shear bottom of a cylinder. In order to use this functionality, you can use shear_bottom property of Cylinder class. The following code snippet shows how to customize Shear Bottom:

from aspose.threed import FileFormat, Scene
from aspose.threed.entities import Cylinder
from aspose.threed.utilities import Vector2, Vector3

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  Create a scene
scene = Scene()
#  Create cylinder 1
cylinder1 = Cylinder(2, 2, 10, 20, 1, False)
#  Customized shear bottom for cylinder 1
cylinder1.shear_bottom = Vector2(0, 0.83)
#  Add cylinder 1 to scene
scene.root_node.create_child_node(cylinder1).transform.translation = Vector3(10, 0, 0)
#  Create cylinder 2
cylinder2 = Cylinder(2, 2, 10, 20, 1, False)
#  Add cylinder to without a ShearBottom to the scene
scene.root_node.create_child_node(cylinder2)
#  Save scene
scene.save("data-dir"  + "CustomizedShearBottomCylinder.obj", FileFormat.WAVEFRONT_OBJ)

The left cylinder has shear_bottom to (0, 0.83) while the right one is an ordinal cylinder.

Create Fan-Cylinder

Aspose.3D for Python via .NET allows creating a fan cylinder. In order to use this functionality, you can set generate_fan_cylinder property of Cylinder class to True. The following code snippet shows how to use this functionality:

from aspose.threed import FileFormat, Scene
from aspose.threed.entities import Cylinder
from aspose.threed.utilities import MathUtils, Vector3

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  Create a Scene
scene = Scene()
#  Create a cylinder
fan = Cylinder(2, 2, 10, 20, 1, False)
#  Set GenerateGanCylinder to true
fan.generate_fan_cylinder = True
#  Set ThetaLength
fan.theta_length = MathUtils.to_radian(270)
#  Create ChildNode
scene.root_node.create_child_node(fan).transform.translation = Vector3(10, 0, 0)
#  Create a cylinder without a fan
nonfan = Cylinder(2, 2, 10, 20, 1, False)
#  Set GenerateGanCylinder to false
nonfan.generate_fan_cylinder = False
#  Set ThetaLengeth
nonfan.theta_length = MathUtils.to_radian(270)
#  Create ChildNode
scene.root_node.create_child_node(nonfan)
#  Save scene
scene.save("data-dir"  + "CreateFanCylinder.obj", FileFormat.WAVEFRONT_OBJ)

The left cylinder has generate_fan_cylinder = False and the right one has generate_fan_cylinder = True.
