utility functions to sample vertices on or inside a triangle mesh or other geometries
◆ poissonSample() [1/2]
Computes samples on a geometry's surface that are not closer to each other than a given distance.
- Parameters
-
| [in] | geometry | The geometry that defines the surface on which the samples get created |
| [in] | transform | The geometry's global pose |
| [in] | worldBounds | The geometry's bounding box |
| [in] | r | The closest distance two surface samples are allowed to have |
| [out] | result | Equally distributed samples on and if specified inside the triangle mesh |
| [in] | rVolume | The average distance of samples inside the mesh. If set to zero, samples will only be placed on the mesh's surface |
| [in] | axisAlignedBox | A box that limits the space where samples can get created |
| [in] | boxOrientation | The orientation of the box that limits the space where samples can get created
|
| [in] | maxNumSamples | If larger than zero, the sampler will stop when the sample count reaches maxNumSamples |
| [in] | numSampleAttemptsAroundPoint | Number of repetitions the underlying algorithm performs to find a new valid sample that matches all criteria like minimal distance to existing samples etc. |
◆ poissonSample() [2/2]
Computes samples on a triangle mesh's surface that are not closer to each other than a given distance. Optionally the mesh's interior can be filled with samples as well.
- Parameters
-
| [in] | mesh | The triangle mesh
|
| [in] | r | The closest distance two surface samples are allowed to have |
| [out] | result | Equally distributed samples on and if specified inside the triangle mesh |
| [in] | rVolume | The average distance of samples inside the mesh. If set to zero, samples will only be placed on the mesh's surface
|
| [out] | triangleIds | Optional output containing the index of the triangle for all samples on the mesh's surface. The array will contain less entries than output vertices if volume samples are active since volume samples are not on the surface. |
| [out] | barycentricCoordinates | Optional output containing the barycentric coordinates for all samples on the mesh's surface. The array will contain less entries than output vertices if volume samples are active since volume samples are not on the surface. |
| [in] | axisAlignedBox | A box that limits the space where samples can get created |
| [in] | boxOrientation | The orientation of the box that limits the space where samples can get created
|
| [in] | maxNumSamples | If larger than zero, the sampler will stop when the sample count reaches maxNumSamples |
| [in] | numSampleAttemptsAroundPoint | Number of repetitions the underlying algorithm performs to find a new valid sample that matches all criteria like minimal distance to existing samples etc. |
