Builds MeshGeometry3D objects.

Performance tips for MeshGeometry3D (See MSDN)

High impact: Mesh animation—changing the individual vertices of a mesh on a per-frame basis—is not always efficient in Windows Presentation Foundation (WPF). To minimize the performance impact of change notifications when each vertex is modified, detach the mesh from the visual tree before performing per-vertex modification. Once the mesh has been modified, reattach it to the visual tree. Also, try to minimize the size of meshes that will be animated in this way.

Medium impact: When a mesh is defined as abutting triangles with shared vertices and those vertices have the same position, normal, and texture coordinates, define each shared vertex only once and then define your triangles by index with TriangleIndices.

Low impact: To minimize the construction time of large collections in Windows Presentation Foundation (WPF), such as a MeshGeometry3D’s Positions, Normal vectors, TextureCoordinates, and TriangleIndices, pre-size the collections before value population. If possible, pass the collections’ constructors prepopulated data structures such as arrays or Lists.

CheckPerformanceLimits() публичный Метод

Checks the performance limits.

See MSDN. Try to keep mesh sizes under these limits: Positions : 20,001 point instances TriangleIndices : 60,003 integer instances

public CheckPerformanceLimits ( ) : void
Результат	void

GetCircle() публичный статический Метод

Gets a circle section (cached).

public static GetCircle ( int thetaDiv ) : IList
thetaDiv	int	/// The number of division. ///
Результат	IList

MeshBuilder() публичный Метод

Initializes a new instance of the MeshBuilder class.

Normal and texture coordinate generation are included.

public MeshBuilder ( ) : System
Результат	System

MeshBuilder() публичный Метод

Initializes a new instance of the MeshBuilder class.

public MeshBuilder ( bool generateNormals, bool generateTextureCoordinates ) : System
generateNormals	bool	/// Generate normal vectors. ///
generateTextureCoordinates	bool	/// Generate texture coordinates. ///
Результат	System

Scale() публичный Метод

Scales the positions (and normal vectors).

public Scale ( double scaleX, double scaleY, double scaleZ ) : void
scaleX	double	/// The X scale factor. ///
scaleY	double	/// The Y scale factor. ///
scaleZ	double	/// The Z scale factor. ///
Результат	void

SubdivideLinear() публичный Метод

Performs a linear subdivision of the mesh.

public SubdivideLinear ( bool barycentric = false ) : void
barycentric	bool	/// Barycentric(?) if set to true . ///
Результат	void

ToMesh() публичный Метод

Converts the geometry to a MeshGeometry3D .

public ToMesh ( bool freeze = false ) : System.Windows.Media.Media3D.MeshGeometry3D
freeze	bool	/// freeze the mesh if set to true . ///
Результат	System.Windows.Media.Media3D.MeshGeometry3D
