PxSDFSample

Defined in include/foundation/PxMathUtils.h

static inline PxReal PxSDFSample(const PxReal *sdf, const PxVec3 &localPos, const PxVec3 &sdfBoxLower, const PxVec3 &sdfBoxHigher, const PxReal sdfDx, const PxReal invSdfDx, const PxU32 dimX, const PxU32 dimY, const PxU32 dimZ, PxReal tolerance)

Samples the signed distance field (SDF) at a given local position.

This function samples the SDF at a given local position within the defined box bounds and calculates the interpolated distance value. It handles grid clamping and ensures that the sampled value is within the tolerance limit.

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

  • tolerance – [in] The tolerance for clamping the grid points

Returns

The sampled SDF value
