Constructors

GLVertexManager(bool)

Create a new gl vertex manager that can be added to the gl model through AddCustomVertexManager(GLVertexManager).

public GLVertexManager(bool expandModelBBox = true)

Parameters

expandModelBBox bool

If false adding vertexes to this vertex manager doesn't affects the gl model bbox. (Default: true).

Properties

ExpandModelBBox

Flag to state if vertex added to this vertex manager imply expansion of the gl model (Default: true).
More (custom) vertex manager can be registered into the gl model, may for temporary purpose and setting this variable to false at the construct of these custom vertex manager allow to unaffect the gl model bbox.
Should be used to avoid the zoomfit to evaluate temporary vertex manager figures.
GLVertexManager

public bool ExpandModelBBox { get; }

Property Value

bool

FigureCount

Actual size of registered figures list.

public int FigureCount { get; set; }

Property Value

int

Figures

Enumerates vertex manager registered figures.

public IEnumerable<GLFigureBase> Figures { get; }

Property Value

IEnumerable<GLFigureBase>

LBBox

BBox of registered figure vertexes [local].

public BBox LBBox { get; }

Property Value

BBox

TriangleCount

Property Value

int

VertexCount

Actual size of GLVertexStruct vertex list.

public int VertexCount { get; set; }

Property Value

Methods

AddFigure(GLFigureBase)

Adds given figure to the vertex manager.
All vertexes belonging to the figure's primitives will be added. Emits FigureAdded event.

public void AddFigure(GLFigureBase figure)

Parameters

figure GLFigureBase

Figure to add.

AddFigure(params GLFigureBase[])

Adds given figures to the vertex manager.
All vertexes belonging to the figures primitives will be added. Emits FigureAdded event.

public void AddFigure(params GLFigureBase[] figures)

Parameters

figures GLFigureBase[]

Figures to add.

AddFigure(IEnumerable<GLFigureBase>)

Adds given figures to the vertex manager.
All vertexes belonging to the figures primitives will be added. Emits FigureAdded event.

public void AddFigure(IEnumerable<GLFigureBase> figures)

Parameters

figures IEnumerable<GLFigureBase>

Figures to add.

Clear()

Clear all vertexes and figures from the vertex manager, and emit FiguresCleared and Invalidated event.

public void Clear()

GetVboArray()

Used internally by the GLModel.RenderVertexManager to render the scene.

Contains the list of vertex structs directly mapped to the gpu.
This array will be built each time a vertex changes from the ToArray() of the list Vertexes. To avoid performance penalty in a scenario where you need to change the position of a figure you can use ObjectMatrix that doesn't affects at all vertexes because is a figure related information forwarded to the gl pipeline shader through UNINAME_uObject.

public GLVertexStruct[] GetVboArray()

Returns

GLVertexStruct[]

OnPropertyChanged(string?)

invoke this method to forward propertchanged event notification. note: not needed to specify propertyName set by compiler service to called property.

protected void OnPropertyChanged(string? propertyName = null)

Parameters

propertyName string

RecomputeLBBox()

Recompute bbox [local] of all figure/primitive vertexes upading LBBox.
Used internally after figure/primitive deletion. REVIEW: may improved

public BBox RecomputeLBBox()

Returns

BBox

RemoveFigure(GLFigureBase)

Remove given figure from the vertex manager.
All vertexes belonging to the figures primitives will be removed. Emits FigureRemoved event.

public bool RemoveFigure(GLFigureBase figure)

Parameters

figure GLFigureBase

Figure to remove.

Returns

bool

True if figure effectively removed.

RemoveFigure(params GLFigureBase[])

Remove given figures from the vertex manager.
All vertexes belonging to the figures primitives will be removed. Emits FigureRemoved event.

public int RemoveFigure(params GLFigureBase[] figures)

Parameters

figures GLFigureBase[]

Figures to remove.

Returns

int

Count of figures effectively removed.

RemoveFigure(IEnumerable<GLFigureBase>)

Remove given figures from the vertex manager.
All vertexes belonging to the figures primitives will be removed. Emits FigureRemoved event.

public int RemoveFigure(IEnumerable<GLFigureBase> figures)

Parameters

figures IEnumerable<GLFigureBase>

Figures to remove.

Returns

int

Count of figures effectively removed.

Events

FigureAdded

Event emitted when a figure was added.

public event FigureEvent? FigureAdded

Event Type

FigureEvent

FigureRemoved

Event emitted when a figure was removed.

public event FigureEvent? FigureRemoved

Event Type

FiguresCleared

Event emitted when all figures cleared.
The list of figures removed is reported through the event argument of FiguresEvent delegate.

public event FiguresEvent? FiguresCleared

Invalidated

Event emitted when a vertex was added or removed or all vertexes cleared.

Its used by the GLModel to track the model changes and emit a ViewInvalidated event.
