`:samplesurface` does not work when important points are not in the final geometry

fhagemann opened this issue ยท 2 comments

The function get_scale that scales the distance between points for :samplesurface plotting does not work for geometries, for which the important points are not in the final geometry (excluded in CSGDifference or CSGIntersection).

Minimum working example

Detector configuration file

units:
  length: mm
  angle: deg
grid: 
  coordinates: cartesian
  axes:
    x: 
      from: -3
      to: 3
    y:
      from: -3
      to: 3
    z: 
      from: -3
      to: 3
medium: vacuum
detectors:
- semiconductor:
    material: HPGe
    geometry:
      intersection:
        - box: 
            widths: [2,2,2]
        - sphere:
            r: 1.41421356237
  contacts:
    - id: 1
      potential: 100
      geometry:
        tube:
          r: 1
          h: 0
          origin: [0,0,1]
    - id: 2
      potential: 0
      geometry:
        tube:
          r: 1
          h: 0
          origin: [0,0,-1]

Plotting the detector works for :csg, :mesh3d and :wireframe:

using SolidStateDetectors
using Plots; gr(fmt = :png)
sim = Simulation("MWEsamplesurface.yaml");
plot(sim.detector.semiconductor, size = (500,500), st = :mesh3d, color = :lightgray, lw = 0.5)
plot!(sim.detector)

csg

but fails for :samplesurface:

plot(sim.detector, show_semiconductor = true, st = :samplesurface, size = (500,500), n_samples = 50)

It looks like this is because the filter! method in get_scale results in points being empty.

filter!(p -> in(p,csg), points)

A quick-and-dirty fix would be to add

if isempty(points) points = [point for p in primitives(csg) for s in surfaces(p) for point in vertices(s, 4)] end

in the line after, which results in
samplesurface

But there might be more elegant solutions to solve this.

There also seems to be a problem with get_world_limits_from_objects if theaxes of the grid are not specified in the configuration file but determined from the objects.
