reprojection

---

Declaration

static func reprojection(aspect: Float, fovRadians: Float, zNear: Float, zFar: Float, referenceView: matrix_float4x4, targetView: matrix_float4x4, backProjectionDistance: Float = 0.9) -> matrix_float3x3

Summary

Returns a 3×3 homography matrix as matrix_float3x3 that reprojects
image coordinates from a reference camera view into a target camera view.
The image coordinates are expected to be normalized [0..1].

Returns

A 3×3 homography matrix in column-major order.

Parameters

Name	Type	Summary
aspect	Float	The aspect ratio of the image (width / height).
fovRadians	Float	The vertical field of view in radians.
zNear	Float	Near clipping plane distance.
zFar	Float	Far clipping plane distance.
referenceView	matrix_float4x4	The reference camera view.
targetView	matrix_float4x4	The target camera view.
backProjectionDistance	Float	Depth at which to reproject, normalized between clipping planes near (0) and far (1). Recommended: 0.9.
