class PxPoissonSampler : public PxUserAllocated

Sampler to generate Poisson Samples locally on a triangle mesh or a shape.

For every local addition of new samples, an individual sampling density can be used.

Subclassed by PxTriangleMeshPoissonSampler

Public Functions

virtual void setSamplingRadius(PxReal samplingRadius) = 0

Sets the sampling radius.

Parameters

samplingRadius – [in] The closest distance two surface samples are allowed to have. Changing the sampling radius is a bit an expensive operation.

virtual void addSamples(const PxArray<PxVec3> &samples) = 0

Adds samples.

Parameters

samples – [in] The samples to add. Adding samples is a bit an expensive operation.

virtual PxU32 removeSamples(const PxArray<PxVec3> &samples) = 0

Adds samples.

Parameters

samples – [in] The samples to remove. Removing samples is a bit an expensive operation.

Returns

Returns the number of removed samples. If some samples were not found, then the number of actually removed samples will be smaller than the number of samples requested to remove

virtual void addSamplesInSphere(const PxVec3 &sphereCenter, PxReal sphereRadius, bool createVolumeSamples = false) = 0

Adds new Poisson Samples inside the sphere specified.

Parameters

  • sphereCenter – [in] The sphere’s center. Used to define the region where new samples get added.

  • sphereRadius – [in] The sphere’s radius. Used to define the region where new samples get added.

  • createVolumeSamples – [in] If set to true, samples will also get generated inside of the mesh, not just on its surface.

virtual void addSamplesInBox(const PxBounds3 &axisAlignedBox, const PxQuat &boxOrientation, bool createVolumeSamples = false) = 0

Adds new Poisson Samples inside the box specified.

Parameters

  • axisAlignedBox – [in] The axis aligned bounding box. Used to define the region where new samples get added.

  • boxOrientation – [in] The orientation making an oriented bounding box out of the axis aligned one. Used to define the region where new samples get added.

  • createVolumeSamples – [in] If set to true, samples will also get generated inside of the mesh, not just on its surface.

virtual const PxArray<PxVec3> &getSamples() const = 0

Gets the Poisson Samples.

Returns

Returns the generated Poisson Samples
