/vis/viewer/set/

Set view parameters of current viewer.

Sub-directories :

Commands :

all [from-viewer-name]

Copies view parameters.
Copies view parameters (except the autoRefresh status) from from-viewer to current viewer.

Available at all Geant4 states.

Parameters

from-viewer-name

type s

autoRefresh [auto-refresh]

Sets auto-refresh.
If true, view is automatically refreshed after a change of view parameters.

Available at all Geant4 states.

Parameters

auto-refresh

type b

Omittable : default value = 0

auxiliaryEdge [edge]

Sets visibility of auxiliary edges
Auxiliary edges, i.e., those that are part of a curved surface, sometimes called soft edges, become visible/invisible.

Available at all Geant4 states.

Parameters

edge

type b

Omittable : default value = 0

culling [culling-option] [action] [density-threshold] [unit]

Set culling options.
"global": enables/disables all other culling options.
"coveredDaughters": culls, i.e., eliminates, volumes that would not be seen because covered by ancester volumes in surface drawing mode, and then only if the ancesters are visible and opaque, and then only if no sections or cutaways are in operation. Intended solely to improve the speed of rendering visible volumes.
"invisible": culls objects with the invisible attribute set.
"density": culls volumes with density lower than threshold. Useful for eliminating "container volumes" with no physical correspondence, whose material is usually air. If this is selected, provide threshold density and unit (g/cm3 mg/cm3 or kg/m3).

Available at all Geant4 states.
