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.

GpuGeometry

The geometry of one bottom-level acceleration structure: triangles from a vertex buffer, or boxes around custom shapes that an @intersection shader tests.

public class GpuGeometry

triangles

Triangles whose corners are consecutive triples of positions.

public static fun triangles(positions: GpuBuffer<GpuVec3>): GpuGeometry

boxes

Custom shapes, one per pair of bounds corners: each box is its minimum corner followed by its maximum corner.

public static fun boxes(bounds: GpuBuffer<GpuVec3>): GpuGeometry

indexed

Builds triangles from consecutive triples of indices into the positions instead of consecutive positions, and returns this geometry. Only for triangles.

public fun indexed(indices: GpuBuffer<uint>): GpuGeometry

opaque

Sets whether the geometry is opaque, and returns this geometry. Any-hit shaders only run for non-opaque geometry. Defaults to true.

public fun opaque(value: bool): GpuGeometry
