# USDValue.Vec3i A 3-component 32-bit integer vector. ``` @frozen struct Vec3i ``` ## Topics ### Initializers [`init()`](/documentation/USDKit/USDValue/Vec3i/init()) Creates a zero vector. [`init(SIMD3)`](/documentation/USDKit/USDValue/Vec3i/init(_:)) Creates a vector from a `SIMD3`. [`init(Int, Int, Int)`](/documentation/USDKit/USDValue/Vec3i/init(_:_:_:)-1jo3u) Creates a vector with the given components. [`init(Int32, Int32, Int32)`](/documentation/USDKit/USDValue/Vec3i/init(_:_:_:)-25s85) ### Instance Properties [`var simd: SIMD3`](/documentation/USDKit/USDValue/Vec3i/simd) The vector as a `SIMD3`. [`var x: Int32`](/documentation/USDKit/USDValue/Vec3i/x) [`var y: Int32`](/documentation/USDKit/USDValue/Vec3i/y) [`var z: Int32`](/documentation/USDKit/USDValue/Vec3i/z) ### Subscripts [`subscript(Int) -> Int32`](/documentation/USDKit/USDValue/Vec3i/subscript(_:)) Accesses the component at the specified index. ## Relationships ### Conforms To [`Copyable`](/documentation/Swift/Copyable) [`BitwiseCopyable`](/documentation/Swift/BitwiseCopyable) [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`Escapable`](/documentation/Swift/Escapable) [`Hashable`](/documentation/Swift/Hashable) [`USDValueProtocol`](/documentation/USDKit/USDValueProtocol) [`Equatable`](/documentation/Swift/Equatable) [`Sendable`](/documentation/Swift/Sendable) [`CustomStringConvertible`](/documentation/Swift/CustomStringConvertible) [`Value`](/documentation/USDKit/USDPrim/Attribute/Value) [`MetadataValue`](/documentation/USDKit/USDStage/Object/MetadataValue) --- Copyright © 2026 Apple Inc.
