FieldCrop

The FieldCrop node crops a field to a bounding box. Many fields are infinite in extent but may need to be cropped in order to view or render them.

Inputs and Controls

Connection Type	Connection Name	Function
Input	fld	An input for connecting to Field that you wish to crop.

Control (UI)	Knob (Scripting)	Default Value	Function
FieldCrop Tab
Edges	edges	Ignore	Tells the node what to do when cropping outside of bounds. Select from Ignore, Clamp, or Value. If Value is selected, the Value knob below will be enabled.
Value	value	x = 0, y = 0, z = 0	Specifies the x, y, and z values of the field outside the cropped bounding box.
Bounds	bounds	x = 0, y = 0, n = 0, r = 2, t = 1, f = 1	The new bounds of the field.
Set bounds from input	set_bbox	N/A	Set the bounds knob from the input field bounds (if any)
Display Tab
Draw Bounding Box	preview_bounds	Unchanged	Draw the bounding box of the field if it has one. Select between On, Off, and Unchanged. Unchanged means that this option is inherited from nodes above it in the node graph. By inheriting On or Off from above, this means this setting only needs to be edited in one node to affect the display across all Field nodes in the node graph.
Draw Preview	preview_on	Unchanged	Draw a rough preview of the field. Select between On, Off, and Unchanged. Unchanged means that this option is inherited from nodes above it in the node graph. By inheriting On or Off from above, this means this setting only needs to be edited in one node to affect the display across all Field nodes in the node graph.
Opacity	preview_opacity	1	The opacity at which to draw the preview.
Scale	preview_scale	1	A value by which the field is multiplied before drawing. You may need to increase this to display faint volumes for example.
Offset	preview_offset	0	A value added to the field before drawing (after scaling).
Detail	preview_detail	1	The detail level at which the preview is drawn. Large values are more accurate but slower to draw.
