faces
Controls the visual representation of a
polytope group. When
faces is
yes (the default), the polyhedron is represented
by solid polygons, that users can see from the outside or from the inside.
When
faces is
no, the polyhedron is represented by wired
lines connecting the vertices.
Example: <group ... faces="yes"/> (default)
Allowed values: yes, no (optional)
red, green, blue
Set the color of a polytope group, between black (0.0, 0.0, 0.0)
and white (1.0, 1.0, 1.0).
Example: <group ... red="0.0" green="1.0" blue="1.0"/> (default)
(defined in GAMGI_MESA_GROUP_R, GAMGI_MESA_GROUP_G
and GAMGI_MESA_GROUP_B)
Allowed values: 0.0 - 1.0 (optional, coupled)
scale
Change the group size, including its child objects.The visual representation
of an object is always scaled by its own scale factor multiplied by the scale
factor of all its parent objects until layer, inclusive.
Polytope groups are scaled around the group center, while
Container groups are scaled around the viewport center. This happens
because
Polytope groups have a geometric center, defined by the
polyhedra, while
Container groups may have only atoms, and using its
geometric center as the scaling center has the weird effect that moving one
atom changes the visual representation of the other atoms, because the
scaling center and thus the scaling transformation has changed!
Example: <group ... scale="1.0"/> (default)
(defined in GAMGI_MESA_SCALE)
Allowed values: positive real (optional)
