numberCoefficients System.Int32
Number of coefficients per sample location. When using spherical harmonic (SH) precomputed radiance transfer (PRT), the number of coefficients should be Order2, where Order is the order of the SH evaluation. Order must be in the range of SphericalHarmonics.MinimumOrder to SphericalHarmonics.MaximumOrder, inclusive.
usage Microsoft.DirectX.Direct3D.DeclarationUsage
A DeclarationUsage object that describes vertex usage of the mesh.
usageIndexStart System.Int32
Starting index for coefficients to be stored in the mesh.
scene Microsoft.DirectX.Direct3D.Mesh
A Mesh object that will store coefficients.
