Detailed Description
Global state variables for the neuron visualization.
This header declares all global variables used throughout the neuron viewer application. These variables manage the visualization state, camera controls, and current neuron data.
- Warning
- Global variables should be used sparingly and only for truly global state that needs to be accessed across multiple translation units.

Variable Documentation
◆ currentNodes
|
extern |
Currently loaded neuron nodes for rendering.
Currently loaded neuron nodes for rendering.
This vector holds the SWC nodes of the currently loaded neuron. It's used throughout the application for rendering and processing.
- Note
- Updated when a new file is loaded via openNeuronFile()
- See also
- SWCNode
◆ dragging
|
extern |
Mouse drag state flags.
These track the current drag operation:
- dragging: True during left-button rotation
- rightDragging: True during right-button panning
Mouse drag state flags.
◆ graph
|
extern |
The main neuron graph data structure.
The main neuron graph data structure.
This object holds the complete neuron graph structure and provides methods for loading, processing, and querying the neuron morphology.
- See also
- NeuronGraph class for available operations
◆ help
|
extern |
Help text displayed in the help window.
Help text displayed in the help window.
Contains formatted text describing the application's keyboard and mouse controls. The text is displayed when the user presses the 'H' key or when explicitly requested.
- See also
- printHelpText()
◆ helpWindow
|
extern |
Pointer to the help window (nullptr if not open)
Pointer to the help window (nullptr if not open)
This is the main window used for displaying the help text. Initialized to nullptr and created when the help window is shown.
- Note
- Managed by the main application loop
- See also
- showHelpWindow() in the main application file
◆ lastX
|
extern |
Last recorded mouse cursor position.
Used to calculate mouse movement deltas for smooth camera control.
Last recorded mouse cursor position.
◆ lastY
| double lastY |
◆ panX
|
extern |
Camera pan offset in X and Y directions.
These values control the 2D panning of the view:
- panX: Horizontal pan (positive = right)
- panY: Vertical pan (positive = up)
Camera pan offset in X and Y directions.
◆ panY
| double panY |
◆ refineDelta
|
extern |
Refinement parameter for mesh generation.
Refinement parameter for mesh generation.
Controls the level of detail in the generated geometry. Higher values result in coarser meshes, while lower values produce more detailed meshes. Used in cubic spline interpolation.
- Note
- Initialized to 8.0 for a coarse starting point
- See also
- allCubicSplineResampledTrunks()
◆ renderMode
|
extern |
Current rendering mode (1-5)
Controls how the neuron is rendered:
- 1: Basic line rendering
- 2: Cylinder rendering
- 3: Spheres at nodes
- 4: Full 3D rendering
- 5: Debug rendering mode
Current rendering mode (1-5)
◆ rightDragging
| bool rightDragging |
◆ rotateX
|
extern |
Camera rotation around X and Y axes (in degrees)
These angles control the 3D view orientation:
- rotateX: Rotation around the X-axis (vertical rotation)
- rotateY: Rotation around the Y-axis (horizontal rotation)
Camera rotation around X and Y axes (in degrees)
◆ rotateY
| double rotateY |
◆ zoom
|
extern |
Camera zoom factor (higher values = more zoomed in)
Camera zoom factor (higher values = more zoomed in)
