Bend Along Surface Field¶
Functionality¶
This node generates a Vector Field, which bends some part of 3D space along the provided Surface object.
Inputs¶
This node has the following inputs:
Surface. The surface to bend the space along. This input is mandatory.
Src U Min, Src U Max. Minimum and maximum value of the first of orientation coordinates, which define the part of space to be bent. For example, if the Object vertical axis parameter is set to Z, then these are minimum and maximum values of X coordinates. Default values are -1 and 1.
Src V Min, Src V Max. Minimum and maximum value of the second of orientation coordinates, which define the part of space to be bent. For example, if the Object vertical axis parameter is set to Z, then these are minimum and maximum values of Y coordinates. Default values are -1 and 1.
The field bends the part of space, which is between Src U Min and Src U Max by one axis, and between Src V Min and Src V Max by another axis. For example, with default settings, the source part of space is the space between X = -1, X = 1, Y = -1, Y = 1. The behaviour of the field outside of these bounds is not guaranteed.
Parameters¶
This node has the following parameters:
Object vertical axis. This defines which axis of the source space should be mapped to the normal axis of the surface. The available values are X, Y and Z. The default value is Z. This means that XOY plane will be mapped onto the surface.
Auto scale. If checked, scale the source space along the vertical axis, trying to match the scale coefficient for two other axes. Otherwise, the space will not be scaled along the vertical axis. Unchecked by default.
As 2D. If checked, it will discard the vertical axis. Enable to bend flat objects. Improves performance.
Flip surface. This parameter is only available in the node’s N panel. If checked, then the surface will be considered as flipped (turned upside down), so the vector field will also turn the space upside down. Unchecked by default.
Outputs¶
This node has the following output:
Field. The generated bending vector field.
