PerspectiveAngle Property

The field of view angle, in degrees when the Projection property is set to ProjectionType.Perspective

Syntax

Visual Basic
C#

'Declaration
 
<DescriptionAttribute("The field of view angle, in degrees when the Projection property is set to ProjectionType.Perspective")>

<DefaultValueAttribute()>

<CategoryAttribute("General")>

Public Property PerspectiveAngle As Single

'Usage
 
Dim instance As View

Dim value As Single

 

instance.PerspectiveAngle = value

 

value = instance.PerspectiveAngle

[Description("The field of view angle, in degrees when the Projection property is set to ProjectionType.Perspective")]

[DefaultValue()]

[Category("General")]

public float PerspectiveAngle {get; set;}

Remarks

The default perspective angle is 65 degrees. Note that this property will accept only values in the range [0.01, 179.99], because values of 0 and 180 are invalid. Try to avoid setting this property to values close to the range because this may result in a deep viewing frustum with lower depth resolution.

Example

The following C# example modifies the projection applied on the chart camera and the perspective angle:

Visual Basic

Dim chartView As View = (CType(ChartControl.Charts(0), Chart)).View 

chartView.Projection = ProjectionType.Perspective

chartView.PerspectiveAngle = 90

View chartView = ((NChart)NChartControl.Charts[0]).View;

chartView.Projection = ProjectionType.Perspective;

chartView.PerspectiveAngle = 90;

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
