reprojection

Returns a 3×3 homography matrix (android.graphics.Matrix) that reprojects image coordinates from a reference camera view into a target camera view. This is typically used to transform 2D image-space coordinates (normalized in [0..1]) from one camera perspective to another, e.g. for aligning visual overlays between AR frames.

Declaration

fun reprojection(aspect: Float, fovRadians: Float, zNear: Float, zFar: Float, referenceView: FloatArray, targetView: FloatArray, backProjectionDistance: Float = 0.9f): Matrix

Summary

Returns a 3×3 homography matrix (android.graphics.Matrix) that reprojects image coordinates from a reference camera view into a target camera view. This is typically used to transform 2D image-space coordinates (normalized in [0..1]) from one camera perspective to another, e.g. for aligning visual overlays between AR frames.

Returns

A 3×3 homography matrix represented as an android.graphics.Matrix.
