property has_parent

Get a boolean noting whether this State has a parent.

property modifier

Get or set the modifier to be applied to the parent in this state.

property modifier_direct

Get or set a modifier for the parent to be used in direct studies.

If None, it will be the same as the modifier of this state. This property is only used in 2-phase and 5-phase studies and should usually be left as None in 2-phase studies. In 5-phase studies, this will be used for the 5th phase.

property mtxs_default

Get a boolean noting whether the vmtx_geometry and dmtx_geometry are None.

This indicates that the vmtx_geometry and dmtx_geometry are both just a flipped version of the parent geometry.

property parent

Get the parent of this State if assigned. None if not assigned.

property shades

Get or set an array of StateGeometry objects to be included with this state.

The StateGeometry objects cannot already have another parent state.

property vmtx_geometry

Get or set a Face3D to be used for the inward-facing vmtx file.

If None, it will be a flipped (inward-facing) version of this state’s parent. Note that this property is only used in 3-phase and 5-phase studies and its usual purpose is to account for thickness of the tmtx (BSDF) layer. Also note that the gen_geo_from_vmtx_offset or gen_geos_from_tmtx_thickness methods can be used to automatically generate this geometry without the need to set it here.
