Genrate a mesh with corresponding test points from a Rhino Brep (or Mesh).

The resulting mesh will be in a format that the "LB Spatial Heatmap" component will accept.

### Inputs

* **geometry \[Required]**

Brep or Mesh from which to generate the points and grid.

* **grid\_size \[Required]**

Number for the size of the test grid.

* **offset\_dist**

Number for the distance to move points from the surfaces of the input \_geometry. Typically, this should be a small positive number to ensure points are not blocked by the mesh. (Default: 0).

* **quad\_only**

Boolean to note whether meshing should be done using Rhino's defaults (False), which fills the entire \_geometry to the edges with both quad and tringulated faces, or a mesh with only quad faces should be generated. FOR ADVANCED USERS: This input can also be a vector object that will be used to set the orientation of the quad-only grid. Note that, if a vector is input here that is not aligned with the plane of the input \_geometry, an error will be raised.

### Outputs

* **points**

Test points at the center of each mesh face.

* **vectors**

Vectors for the normal direction at each of the points.

* **face\_areas**

Area of each mesh face.

* **mesh**

Analysis mesh that can be passed to the "LB Spatial Heatmap" component.
