Instanced | |
The InstancedMeshGeometryVisual3D type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | GenerateModel3DGroup | GenerateModel3DGroup converts this InstancedMeshGeometryVisual3D into a WPF's Model3DGroup object with many GeometryModel3D objects (each is created form one InstanceData). |
| Update | Update method updates the data for all instances. It must be called after InstancesData are changed. When only some other instances were changed, it is highly recommended to call Update(Int32, Int32, Boolean) and pass startIndex and count as parameters. |
| Update(Boolean) | Update method updates the data for all instances and provides a parameter to specify if bounding box need to be updated. |
| Update(Int32, Int32, Boolean) | Update method updates instance data specified with startIndex, count parameters and updateBounds. This method can be called after some instance transformations or colors were changed. NOTE: If multiple sections of data are changed, do not call this method multiple times - it is faster to call Update only once. |
| UpdateMaterial | UpdateMaterial updates the used specular material. It must be called after the SpecularMaterial is changed. |
| UseInstanceIdColor | After calling UseInstanceIdColor method then the color of each instance is defined by the id (index) of each instance. The addedColor4 is added the id (usually a Color4.Black is used). The lowers 8 bytes of the instance id number are written to blue color, then to the green color, then to red color and the highest byte is written to alpha color. The color can be also used when rendering multiple instanced objects to distinguish between them (for example by using different alpha value). To disable using instance id color call UseInstanceObjectColor or UseSingleObjectColor(Color). |
| UseInstanceObjectColor | UseInstanceObjectColor method can be called after calling the UseSingleObjectColor(Color). This method resets using diffuse color from instances data. |
| UseSingleObjectColor | When UseSingleObjectColor is called, the specified objectColor is used as diffuse color for all instances. This overrides the color defined in the instances data. When color's alpha value is less than 1, then alpha blending is used. To use instance color after calling UseSingleObjectColor, call the UseInstanceObjectColor method. |
Extension Methods| Name | Description | |
|---|---|---|
 | ClearDXAttribute |
Clears the value from DXAttributeType so that IsDXAttributeSet(Visual3D, DXAttributeType) method returns false for that DXAttributeType.
(Defined by Extensions) |
| GetDXAttribute |
Gets the value of the specified DXAttributeType from the specified Visual3D.
If the attributeType does not exists then an exception is thrown.
Use GetDXAttributeOrDefaultT(Visual3D, DXAttributeType) or GetDXAttributeOrDefaultT(Visual3D, DXAttributeType, T) to prevent throwing exception when the value is not set.
(Defined by Extensions) |
| GetDXAttributeCollection |
Gets a DXAttributeCollection will a collection of all DXEngine's attributes set to the specified WPF's object.
Returns null when no DXAttributeCollection was attached to the WPF object.
(Defined by Extensions) |
| GetDXAttributeOrDefaultT |
Gets the value of the specified DXAttributeType from the specified Visual3D.
If the attributeType does not exists then a default value for the type T is returned.
(Defined by Extensions) |
| GetDXAttributeOrDefaultT |
Gets the value of the specified DXAttributeType from the specified Visual3D.
If the attributeType does not exists then the specified defaultValue is returned.
(Defined by Extensions) |
| IsDXAttributeSet |
Returns true if the specified attributeType was set (result is true even if the value is null).
(Defined by Extensions) |
| SetDXAttribute |
Annotates the specified wpfObject with adding or updating a DXEngine's attribute to it.
The attribute is specified with attributeType and its value.
This can be used to annotate WPF's objects with DXEngine's attributes.
