This reference lists the public declarations for this part of the library. See Reading API signatures for parameter and result notation. Shader-only declarations can be used only inside @compute, @vertex, @fragment, inferred helpers and ray tracing shader functions; using them elsewhere is a compile error.

GpuHitGroup

The shaders that handle rays hitting one kind of geometry: a @closest_hit shader, plus optionally an @any_hit shader and, for custom shapes, an @intersection shader. Start from GpuHitGroup.closest and add the optional shaders.

public class GpuHitGroup

closest

A hit group that runs shader, a @closest_hit shader's GpuShaders entry, for the nearest hit.

public static fun closest(shader: GpuStageShader): GpuHitGroup

with_any_hit

Adds an @any_hit shader, and returns this hit group.

public fun with_any_hit(shader: GpuStageShader): GpuHitGroup

with_intersection

Adds an @intersection shader for custom shapes built with GpuGeometry.boxes, and returns this hit group.

public fun with_intersection(shader: GpuStageShader): GpuHitGroup
