Compute gradient of truncated signed distance field
Since R2024a
grad = gradient(mTSDF,points)
grad = gradient(mTSDF,points,InterpolationMethod=interp)
grad = gradient(mTSDF,points) returns the gradient voxels in the vicinity of the specified query points in the truncated signed distance field (TSDF).

grad = gradient(mTSDF,points,InterpolationMethod=interp) specifies the method to use for interpolating the distance field.

meshtsdf
Truncated signed distance field for 3-D meshes, specified as a meshtsdf object.
Example: meshtsdf(meshes,TruncationDistance=5) creates a TSDF for the specified meshes with a truncation distance of 5 meters.
meshtsdf(meshes,TruncationDistance=5)
5
Query points, specified as an N-by-3 matrix, where each row represents an xyz point. N is the total number of query points.
"linear"
"quadratic"
Interpolation method, specified as one of these options:
"linear" — Compute the partial derivatives of the trilinearly-interpolated distance field.
"quadratic" — Compute the partial derivatives of the triquadratically-interpolated distance field.
Gradient values of voxel at each query point, specified as an N-element vector. N is the total number of query points specified in points.
By default, gradient uses the linear interpolation method to determine the gradient. Use the interp argument to change the interpolation method.
