🝖 Bounds

PCGEx | Filter : Bounds

Checks if a point is inside or outside the provided bounds, with options for bounds types and an epsilon adjustment.

Bounds

Set of points which bounds will be checked against.

Properties

Property	Description
Bounds Source	Defines the bounds to be used for tested points.
Bounds Target	Defines the bounds to be used for the input `Bounds` points.
Check Type	The type of bounds x bounds check the filter will do.
Inside Epsilon	Lets you set a small value that will be used to expand the target bounds.

Bounds types

Bounds type
Scaled Bounds	Point’ bounds scaled by point’ scale. These are the bounds shown by default when using the debug node in extent mode.
Density Bounds	Point’ bounds scaled by point’ scale, expanded by point’ steepness property. These are the bounds used by a lot of vanilla PCG nodes.
Bounds	Raw, unscaled point’ bounds.

Point bounds are determined by its BoundsMin and BoundsMax properties.

Check Type

Defines how source bounds are checked against the target bounds. These are fairly standard box/box operations.

Note that the source bounds are first transformed by their point’ transform, and then inverse transformed by the target’ point transform; meaning there can be some artifacts and mathematical variations as a result of applying the matrices.
