VertexFormat enum
The format of a single vertex attribute.
Each value names a component count, scalar type, and bit width. The enum currently covers the 32-bit-per-component scalar types (float, signed integer, unsigned integer) in 1, 2, 3, and 4 component widths. Normalized integer, packed, half-float, BGRA-swizzled, and 64-bit attribute formats will be added in a future release; new values are purely additive and won't affect callers using existing values.

const VertexFormat(bytesPerElement: 8, componentCount: 2) - float32x3 → const VertexFormat
-
Three 32-bit floats (12 bytes).
