addSceneTextsOptions()

GOptions g4display::addSceneTextsOptions

(

)

This helper returns a GOptions object that defines the g4text option. The option supports multiple text items, each item providing:

• text (required)
• color (default "black")
• kind (default "2D"; use "3D" for /vis/scene/add/text)
• layout (default empty; e.g. "right")
• x, y (default 0)
• z (default sentinel GNOT_SPECIFIED_SCENE_TEXT_Z)
• unit (default "cm" for 3D text)
• size (default 24.0)
• dx, dy (default 4.0 for 3D text offsets)

Returns

A GOptions object containing the g4text option definition.

Definition at line 43 of file g4Text.cc.

defineOptions()

GOptions g4display::defineOptions

(

)

This function builds a GOptions object for the module, including:

• g4view : viewer driver/window settings and precision.
• g4camera : initial camera angles.
• g4light : initial light-source angles.
• dawn / useDawn : DAWN view configuration and enable switch.
• g4text : optional scene text entries (added via g4display::addSceneTextsOptions).

Returns

A GOptions instance containing the module option definitions.

(

const std::shared_ptr< GOptions > &

gopts

)

Parameters

gopts

Shared options object to query.

Returns

G4Camera populated from the g4camera node.

Definition at line 49 of file g4display_options.cc.

getG4Dawn()

G4Dawn g4display::getG4Dawn

(

const std::shared_ptr< GOptions > &

gopts

)

The implementation normalizes "null" values to goptions::NODFLT.

Parameters

gopts

Shared options object to query.

Returns

G4Dawn populated from the dawn node.

Definition at line 71 of file g4display_options.cc.

getG4Decorations()

G4Decorations g4display::getG4Decorations

(

const std::shared_ptr< GOptions > &

gopts

)

Parameters

gopts

Shared options object to query.

Returns

G4Decorations populated from the g4decoration node.

Definition at line 87 of file g4display_options.cc.

getG4Light()

G4Light g4display::getG4Light

(

const std::shared_ptr< GOptions > &

gopts

)

Parameters

gopts

Shared options object to query.

Returns

G4Light populated from the g4light node.

Definition at line 60 of file g4display_options.cc.

getG4View()

G4View g4display::getG4View

(

const std::shared_ptr< GOptions > &

gopts

)

Parameters

gopts

Shared options object to query.

Returns

G4View populated from the g4view node.

Definition at line 34 of file g4display_options.cc.

getSceneTexts()

std::vector< G4SceneText > g4display::getSceneTexts

(

const std::shared_ptr< GOptions > &

gopts

)

The function reads the option node named "g4text" and projects each element into a G4SceneText. Missing properties are filled with defaults defined by the option schema.

Parameters

gopts

Shared options object used to access the g4text option node.

Returns

A vector of G4SceneText entries in the order they appear in the option node.
