Surfaces - General curved bézier surface

A complex, space-curving surface defined by 16 points.

The surface is bounded by 4 bézier curves, defined by 12 points. An additional 4 internal points, also following bézier curve rules, create the surface.

The order of selecting the 16 points is fixed.

Parameters

Resolution

The fineness of the curvature can be adjusted. The number of divisions doubles as the entered number increases. The diagrams are made with values of 3, 5, and 6. At 0, the default value is 5. The surface is always smoothed.

Texture min. max.

On the general surface, the texture is always stretched. However, 4 values can adjust where it starts and ends in width and height.

The texture's width and height use X and Y as units. For example, if the min is 0 and the max is 1, the texture starts at the edge of the surface and ends at the opposite edge. In this case, the texture is stretched 1:1 over the surface. This is the default; with 0,0,0,0, the program assumes 0,1,0,1.

The starting point is the top right corner!

  0, 1, 0, 1

  0.5, 1, 0, 1
The texture starts at the middle (0.5) in width and stretches to the end (1).

  0.5, 1.5, 0.5, 1.5
The texture starts at the middle (0.5) and stretches to one and a half times in both width and height.

  0, 3, 0, 3
