Morph Triangles using Curves dialog

To morph triangles using the curves:

1. Select a mesh.
2. Click Mesh Tools tab > Triangles panel > Morph using Curves to display the Morph Triangles using Curves dialog:

   

3. Select the inner and outer items you want to define the morph by, or, if necessary, use the following buttons to create curves to define the inner and outer regions:
   • Click the Snap to Mesh button to create a curve that is snapped to the mesh.
   • Click the Mesh Boundary button to create a curve at the mesh boundary.
   • With a curve selected, click the Offset button to offset the selected curve.
   • Click the Centre of Gravity button to add a point at the centre of gravity.

   The changes to a next to the Outer item and Inner items options to indicate that they have been selected.

   Note: If you create the outer and inner items, they are automatically selected.
4. Choose a Transform the Inside option. Select:
   • None for no morphing of the inside region.
   • Move to move the inside region. Enter X, Y, and Z values to indicate the amount to move along the axes.
   • Rotate to rotate the inner region. Enter a rotation Angle. Click the Reposition button to define a new rotation origin.
   • Scale to increase or decrease the size of the region by entering a scale Factor. For example, to increase the size of the region by 20% enter a Factor of 1.2. By default, Factor is applied in all directions. Use the Lock buttons to suppress scaling in a specific axis.

     Click the Reposition to define a new position for the scale origin.

   • Offset to define the offset for the region in the Distance box.
5. In the Blend list, choose the type of blend you want to use. Select:
   • None to have no blend is between the transformed region and the adjoining regions :

     

   • Smooth to create a smooth curve between adjoining transform regions. The curve is tangential at both edges of the blend region:

     

   • Linear to create a straight-line blend between the two transform regions:

     

   • Smooth to Sharp to create a smooth to sharp blend between the previous region and the current region. This creates a transition that uses a tangential curve next to the first transform region , and a linear blend next to the second transform region :

     

   • Sharp to Smooth to create a sharp to smooth blend between the previous region and the current region. This creates a transition that uses a linear blend next to the first transform region , and a tangential curve next to the second transform region :

     

6. Choose a Transform the Outside option: Select:
   • None for no morphing of the outside region. This is the default.
   • Move to move the outside region. Enter X, Y, and Z values to indicate the amount to move along the axes.
   • Rotate to rotate the outside region. Enter a rotation Angle. Click the Reposition button to define a new rotation origin.
   • Scale to increase or decrease the size of the region by entering a scale Factor. For example, to increase the size of the region by 20% enter a Factor of 1.2. By default, Factor is applied in all directions. Use the Lock buttons to suppress scaling in a specific axis.

     Click the Reposition to define a new position for the scale origin.

   • Offset to define the offset for the region. Enter an offset Distance.
7. Click Preview to view the morph.
8. Click OK to morph the region.
