Read this page as plain text instead: https://www.nianticspatial.com/docs/llms-api-swift/NSDK.NSDKCamera.method-projectionMatrix.txt — same content, easier to parse than this HTML, with each platform's steps kept separate.

Every page in the current release follows the same pattern, so you can build the URL directly instead of fetching an index: a page at /api/swift/<page>/ is at /llms-api-swift/<page>.txt.

projectionMatrix

Declaration

func projectionMatrix(for orientation: UIInterfaceOrientation, viewportSize: CGSize, zNear: CGFloat, zFar: CGFloat) -> simd_float4x4

Summary

Returns a projection matrix for the given orientation and viewport size, with optional near/far clipping.
Pass the same orientation and viewport size used for the view matrix so that 3D content projects correctly.
zFar > 0 uses a finite far plane; zFar <= 0 yields an infinite far plane (e.g. for skyboxes).
