A bottom-level geometry consisting of triangles.

Fields

flags: GeometryFlags

Specifies how the geometry should be built.

The default value is empty.

vertex_format: Format

The format of each vertex in vertex_data.

This works in the same way as formats for vertex buffers.

There is no default value.

vertex_data: Option<Subbuffer<[u8]>>

The vertex data itself, consisting of an array of vertex_format values.

This can be None when calling Device::acceleration_structure_build_sizes, but must be Some otherwise.

The default value is None.

vertex_stride: u32

The number of bytes between the start of successive elements in vertex_data.

This must be a multiple of the smallest component size (in bytes) of vertex_format.

The default value is 0, which must be overridden.

max_vertex: u32

The highest vertex index that may be read from vertex_data.

The default value is 0, which must be overridden.

index_data: Option<IndexBuffer>

If indices are to be used, the buffer holding the index data.

The indices will be used to index into the elements of vertex_data.

The default value is None.

transform_data: Option<Subbuffer<[[f32; 4]; 3]>>

Optionally, a 3x4 matrix that will be used to transform the vertices in vertex_data to the space in which the acceleration structure is defined.

The first three columns must be a 3x3 invertible matrix.

The default value is None.

_ne: NonExhaustive
