%--------------------------------------------------------------------------
% [] = astra_plot_geometry(geometry, varargin)
%
% plot an astra geometry
%
% geometry: any astra geometry, either volume geometry, projection
% geometry or an *.stl file (powered by stlRead).
% varargin: supports a variable number of (ordered and unordered)
% arguments.
%
% the remaining arguments depend on the input:
% if 'geometry' is
% - a volume geometry
% vx_size voxel size in unit of preference. Must
% be same unit that was used to scale the
% projection geometry.
% and as unorderd string-value-pairs
% Magnification magnification factor for the phantom.
% For small phantoms it might be
% necessary to scale the render up as
% otherwise it won't show up in the plot.
% Default = 1
% LineWidth line width for the box wireframe.
% Default = 2
% Color color of the wireframe. Default = 'r'
%
% - a projection geometry (as unordered string-value-pairs)
% RotationAxis if specified, will change the drawn
% rotation axis to provided axis.
% Must be 3-vector. Default value is
% [NaN, NaN, NaN], (meaning do not draw).
% RotationAxisOffset if specified, will translate the drawn
% rotation axis by the provided vector.
% Default = [0, 0, 0]
% VectorIdx index of the vector to visualize if
% vector geometry type. Default = 1
% Color Color for all markers and lines if not
% otherwise specified
% DetectorMarker marker for the detector locations.
% Default = '.'
% DetectorMarkerColor color specifier for the detector marker.
% Default = 'k'
% DetectorLineColor color for the lines drawing the
% detector outline
% DetectorLineWidth line width of detector rectangle
% SourceMarker marker for the source locations
% SourceMarkerColor color specifier for the source marker
% SourceDistance (only for parallel3d and parallel3d_vec)
% distance of source to origin
% OpticalAxisColor Color for drawing the optical axis
%
% - a path to an *.stl file
% magn - magnification factor for vertices in
% CAD file. Default value = 1
