Samples the signed distance field (SDF) at a given local position with gradient computation (deprecated).

Deprecated:

Please use PxSDFSample.

Parameters:

• sdf – [in] A pointer to the SDF data

• localPos – [in] The local position to sample the SDF

• sdfBoxLower – [in] The lower bound of the SDF box

• sdfBoxHigher – [in] The upper bound of the SDF box

• sdfDx – [in] The spacing between grid points in the SDF

• invSdfDx – [in] The inverse of the grid spacing

• dimX – [in] The number of grid points along the x-axis

• dimY – [in] The number of grid points along the y-axis

• dimZ – [in] The number of grid points along the z-axis

• gradient – [out] The resulting gradient vector

• tolerance – [in] The tolerance for clamping the grid points (default is PX_MAX_F32)

Returns:

The sampled SDF value
