Class: TessellationDescriptor

A TessellationDescriptor is the blueprint for tessellation on a mesh: It defines where the different tessellation- cuts will happen on the surface, and coordinates what happens when the mesh is changed.

Returns: void

Private _moveIfCutlinesInOnlyOneDirectionPossible

▸ _moveIfCutlinesInOnlyOneDirectionPossible(): void

Defined in src/model/data/Concepts/TessellationDescriptor.ts:445

This checks if it is possible for some surfaceTessellations to only have cutLines in one direction. If this is possible, we try to move the tessellation that way

Returns: void

Private _notifyUser

▸ _notifyUser(type: TessellationNotificationType): void

Defined in src/model/data/Concepts/TessellationDescriptor.ts:413

Parameters:

Name Type
type TessellationNotificationType

Returns: void

Private _onAnchorTransformsChange

▸ _onAnchorTransformsChange(changeEvent: IAnchorChangeEvent): void

Defined in src/model/data/Concepts/TessellationDescriptor.ts:546

This will be called, when either the mesh anchor, or one of the Anchors of the surface tessellation changes. The TessellationDescriptor should then be realized again.

Parameters:

Name Type
changeEvent IAnchorChangeEvent

Returns: void

Private _onMeshAnchorChange

▸ _onMeshAnchorChange(event: IMeshAnchorChangeEvent): void

Defined in src/model/data/Concepts/TessellationDescriptor.ts:421

Parameters:

Name Type
event IMeshAnchorChangeEvent

Returns: void

Private _removeUnnecessaryTessellations

▸ _removeUnnecessaryTessellations(): void

Defined in src/model/data/Concepts/TessellationDescriptor.ts:554

Returns: void

Private _saveTessellation

▸ _saveTessellation(): void

Defined in src/model/data/Concepts/TessellationDescriptor.ts:384

Returns: void

addSurfaceTessellation

▸ addSurfaceTessellation(surfaceTessellation: SurfaceTessellation, checkForValidSurface: boolean): boolean

Defined in src/model/data/Concepts/TessellationDescriptor.ts:71

Parameters:

Name Type Default Description
surfaceTessellation SurfaceTessellation - The surfaceTessellation to add
checkForValidSurface boolean true whether to check for surfaceTessellations with the same surface and replace them. This can be useful on deserialization, when we can't be sure the anchor is already returning a valid surface.

Returns: boolean

applyAutoTessellation

▸ applyAutoTessellation(): void

Defined in src/model/data/Concepts/TessellationDescriptor.ts:263

Apply a tessellation in the size stored in the compositeModel to the current assembly. When we have a saved tessellation, we first apply it and keep it if it is valid. Otherwise we use the AutoTessellationGenerator to generate a tessellation.

Returns: void

clearSurfaceTessellations

▸ clearSurfaceTessellations(emitEvent: boolean, savePreviousTessellation: boolean): void

Defined in src/model/data/Concepts/TessellationDescriptor.ts:153

Clears all surfaceTessellations from the object.

Parameters:

Name Type Default Description
emitEvent boolean true If an event should be emitted
savePreviousTessellation boolean false If we want to save the tessellation on the object for later use.

Returns: void
