Public Instance Constructors
OpenGlDevice Constructor
|
Initializes a new instance of the OpenGlDevice class. |
Public Instance Fields
 ColorEnabled (inherited from MNDevice) | |
| DrawEnabled (inherited from MNDevice) | If DrawEnabled = false then the drawmethods don't works. In combination with HitEnabled you can trick: Draw an invisible, but catchenabled object, so you have an invisible hotspot. |
| GenerateNames (inherited from MNComponent) | If GenerateNames is true then a MNName willbe generated if the parent is set to a component with has no name. With GenerateNames is guarantized, the every member of a tree ( except the root ) has a unique name and there is a fullpath, with that the element can be identified. |
| RenderingContext | |
| UpDateCount (inherited from MNComponent) |
Public Instance Properties
 BackColor (inherited from MNDevice) | Retrieves and sets the color of the background |
| Bitmap (inherited from MNDevice) | |
| CatchDistance (inherited from MNDevice) | With this value the magnetism is controlled. Objects, who are nearer as Catchdistance will be added to the HitItemlist. It is the distance in screen coordinate. By default the value is 5 pixels. |
| CatchDistanceF (inherited from MNDevice) | Converts the value CatchDistance in world distance. |
| ClickedPosCount (inherited from MNDevice) | |
| Count (inherited from MNComponent) | Returns the count of children |
| CurrentHit (inherited from MNDevice) | If a hit happens then CurrentHit holds the first element if HitItemlist |
| Currentxyz (inherited from MNDevice) | Returns the 3-point, which is allocated by the mousepointer and magnetism to some objects |
| DesignMode (inherited from MNDevice) | |
| EventServer (inherited from MNDevice) | |
| Eye (inherited from MNDevice) | Returns the point of view. |
| EyeDistance (inherited from MNDevice) | This is the distance from the Eye to the projectionplane. In case of orthogonal projection we have a fix EyeDistance of 30, else the distance is given by WorldWidth/(2*Tan(FieldOfView)); |
| FarClipping (inherited from MNDevice) | Sets or gets the farrclipping distance. She is relative to the Eye. By default she is 50. This means an ob ject, which is farer from the eye than 50 logical unit wil be clipped. |
| FieldOfView (inherited from MNDevice) | Sets the angle of the FieldOfView in degree. An angle of zero indicates that we have a orthogonal projection An angle different to zero indicates that we have a perspective projection. A good angle for that is ~ 20° |
| FontName (inherited from MNDevice) | Sets or gets the name of the current font. A call to drawText uses this font. |
| FontSize (inherited from MNDevice) | Determes the size of the font in logical units. See also drawText |
| Graphics (inherited from MNDevice) | |
| HitEnabled (inherited from MNDevice) | If HitEnabled = true then the selectmechanism works, else it is turned off. Default it is true. See also HitItemlist |
| HitItemlist (inherited from MNDevice) | HitItemlist contains Hititems, which belong to selected drawing elements. This are elements, who lay in the near of the Point p, for which the method Select was called. See also HitItemList |
| Item (inherited from MNComponent) | The default indexer retieves and sets MNComponents |
| Lighting (inherited from MNDevice) | Controls, whether the lighting is on or not. |

| Material (inherited from MNDevice) | Sets and gets the Material. |
| MNName (inherited from MNComponent) | Name of the component. |
| ModelMatrix (inherited from MNDevice) | The ModelMatrix plays an important rule. If scene data are going to the device the they wold be transformed first by the modelmatrix and then by the ProjectionMatrix. After this two transformations the data are laying in a cube, which is bounded by (-1, -1, -1) and (1, 1, 1). In the last step the points are posiionned in the screen by expand into the viewport. You see, that the modelmatrix is a very powerful property. Surface S = new Sphere(4); Device.DrawSurface(S); // save the modelmatrix Device.PushMatrix() Device.ModelMatrix = Device.ModelMatrix * Translation(new (5, 0, 0); // this Sphere has the center at (5 /0 /0 ). Device.DrawSurface(S); Device.ModelMatrix = Device.ModelMatrix * Translation(new (5, 0, 0); // this Sphere has the center at (5 /0 /0 ). Device.DrawSurface(S); // reset the Modelmatrix Device.PopMatrix() |
| Name (inherited from MNDevice) | |
| Navigate (inherited from MNDevice) | If Navigate is true then you can navigate in the scene by pressed mousemoves. |
| NearClipping (inherited from MNDevice) | Sets or gets the nearclipping distance. She is relative to the Eye. By default she is 1. This means an object, which is nearer to the Eye as 1 logical unit will be clipped. |

| ProjectionBase (inherited from MNDevice) | Gets or sets the projectionbase in which the scene will be projected. You can also transform the ... // rotate the projectionbase around her x-axis Base P = Device.ProjectionBase; P = P.mul(Math.Matrix.Rotation(P.Basex, Math.PI/6)); Device.ProjectionBase = P ... |
| ProjectionMatrix (inherited from MNDevice) | Contains the information about the projection of 3D-Data to the screen The matrix will be influenced by setting the FieldOfView. But you can set this directly for example: // initialize ProjectionMatrix by a frustum ProjectionMatrix = Math.Matrix.Frustum(-10, 10, -10, 10, 2, 50); // or ProjectionMatrix = Matrix.Orthogonal(left,right,bottom,top,-20,20); |
