C# Class HelixToolkit.Wpf.MeshBuilder

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.
