Sphere

Base:

UBlueprintFunctionLibrary

Type:

UNSpherePickerLibrary / FNSpherePicker

Header File:

NexusActorPools/Public/NSpherePickerLibrary.h

Provides various functions for generating points [i]nside or [o]n the surface of a sphere using different random generation strategies (deterministic, non-deterministic, seeded).

The UNSpherePickerLibrary wraps the native FNSpherePicker functionality in a Blueprint friendly manner. Should you be wanting to utilize a picker in native code it is best to directly reference FNSpherePicker directly to avoid the abstraction layer as it has a similar API.

Methods

tip

There are Simple variants of all of these methods which removes the inner exclusion when not needed as a minor optimization.

Next Point (IO)

Generates a deterministic point [i]nside or [o]n the surface of a sphere.

info

Uses FNRandom::Deterministic to ensure reproducible results.

Next Point Projected (IO)

Generates a deterministic point [i]nside or [o]n the surface of a sphere, then projects it onto a surface in the world.

info

Uses FNRandom::Deterministic to ensure reproducible results.

Random Point (IO)

Generates a random point [i]nside or [o]n the surface of a sphere.

Random Point Projected (IO)

Generates a random point [i]nside or [o]n the surface of a sphere, then projects it onto a surface in the world.

Random One-Shot Point (IO)

Generates a random point [i]nside or [o]n the surface of a sphere using a provided seed.

Random One-Shot Point Projected (IO)

Generates a random point [i]nside or [o]n the surface of a sphere using a provided seed, then projects it onto a surface in the world.

Random Tracked Point (IO)

Generates a random point [i]nside or [o]n the surface of a sphere while tracking the random seed state.

Random Tracked Point Projected (IO)

Generates a random point [i]nside or [o]n the surface of a sphere while tracking the random seed state, then projects it onto a surface in the world.
