\section f123 Mesh Element Subsampling
Create a new layer populated with a point sampling of the current mesh, At most one sample for each element of the mesh is created. Samples are taking in a uniform way, one for each element (vertex/edge/face); all the elements have the same probabilty of being choosen.
| \c Int | Number of samples | The desired number of samples. The ray of the disk is calculated according to the sampling density. -- |
| \c AbsPerc | Explicit Radius | If not zero this parameter override the previous parameter to allow exact radius specification -- |
| \c Int | MonterCarlo OverSampling | The over-sampling rate that is used to generate the intial Montecarlo samples (e.g. if this parameter is K means thatK x poisson sample points will be used). The generated Poisson-disk samples are a subset of these initial Montecarlo samples. Larger this number slows the process but make it a bit more accurate. -- |
| \c Bool | Base Mesh Subsampling | If true the original vertices of the base mesh are used as base set of points. In this case the SampleNum should be obviously much smaller than the original vertex number.

| \c Bool | Sample Vertexes | For the search of maxima it is useful to sample vertices and edges of the mesh with a greater care. It is quite probably the the farthest points falls along edges or on mesh vertexes, and with uniform montecarlo sampling approachesthe probability of taking a sample over a vertex or an edge is theoretically null.
On the other hand this kind of sampling could make the overall sampling distribution slightly biased and slightly affects the cumulative results. -- |
| \c Bool | Sample Edges | See the above comment. -- |
| \c Bool | Sample FauxEdge | See the above comment. -- |
| \c Bool | Sample Faces | See the above comment. -- |
| \c Int | Number of samples | The desired number of samples. It can be smaller or larger than the mesh size, and according to the choosed sampling strategy it will try to adapt. -- |

| \c Int | Texture Width | A sample for each texel is generated, so the desired texture size is need, only samples for the texels falling inside some faces are generated.
Setting this param to 256 means that you get at most 256x256 = 65536 samples).
If this parameter is 0 the size of the current texture is choosen. -- |
| \c Int | Texture Height | A sample for each texel is generated, so the desired texture size is need, only samples for the texels falling inside some faces are generated.
Setting this param to 256 means that you get at most 256x256 = 65536 samples) -- |

\section f132 Uniform Mesh Resampling
Create a new mesh that is a resampled version of the current one.
| \c AbsPerc | Precision | Size of the cell, the default is 1/50 of the box diag. Smaller cells give better precision at a higher computational cost. Remember that halving the cell size means that you build a volume 8 times larger. -- |
| \c AbsPerc | Offset | Offset of the created surface (i.e. distance of the created surface from the original one).
If offset is zero, the created surface passes on the original mesh itself. Values greater than zero mean an external surface, and lower than zero mean an internal surface.
In practice this value is the threshold passed to the Marching Cube algorithm to extract the isosurface from the distance field representation. -- |
| \c Bool | Clean Vertices | If true the mesh generated by MC will be cleaned by unifying vertices that are almost coincident -- |
| \c Bool | Discretize | If true the position of the intersected edge of the marching cube grid is not computed by linear interpolation, but it is placed in fixed middle position. As a consequence the resampled object will look severely aliased by a stairstep appearance.
Useful only for simulating the output of 3D printing devices. -- |
| \c Bool | Multisample | If true the distance field is more accurately compute by multisampling the volume (7 sample for each voxel). Much slower but less artifacts. -- |
| \c Bool | Absolute Distance | If true a not signed distance field is computed. In this case you have to choose a not zero Offset and a double surface is built around the original surface, inside and outside. Is useful to convrt thin floating surfaces into solid, thick meshes.. t -- |
