Detailed Description

The IfcBSplineSurface is a general form of rational or polynomial parametric surface. The descriptions of symbols used below:

Variable Definition K1 Upper index on U control points K2 Upper index on V control points P_ij Control points w_ij Weights d1 U degree d2 V degree

The control points are ordered as: P₀₀, P₀₁, P₀₂, ..., P_K1(K2-1), P_K1K2

The weights, in the case of the rational subtype, are ordered similarly.

For each parameter, s = u or v, if k is the upper index on the control points and d is the degree for s, the knot array is an array of (k + d + 2) real numbers [s_-d, ...., s_k+1], such that for all indices j in [-d, k]; s_j ≤ s_j+1. This array is obtained from the appropriate u_knots or v_knots list by repeating each multiple knot according to the multiplicity.

Remarks: This definition may not be instantiated.
