AssertAreEqual(expectedPlaneCenter, plane.Bounds.Center, bounds.Length() * 0.01f, "Center");
}示例2: CreateSimpleMesh
/// <summary>
/// Helper function that creates a simple mesh for use in the PlaneFinding API. The mesh is built as tesselated
/// quad spanning the x and y dimensions of the specified Bounds. Each vert in the mesh is randomly perturbed
/// along the z axis with in the specified Bounds. This results in a somewhat more realistic noisy planar mesh
/// that simulates the sort of data we might get from SR.
