wrapT
The wrapping behavior for the T texture coordinate.
Declaration
var wrapT: SCNWrapMode { get set }Discussion
Wrapping modes determine texture mapping behavior for cases where a material’s texture coordinates extend outside the range from 0.0 to 1.0. For example, if you use the contentsTransform property to shrink a texture relative to the surface of a geometry, you use the wrap mode properties to determine whether the texture repeats across the surface.
The T texture coordinate measures the vertical axis of a texture image, increasing from 0.0 at the bottom of the image to 1.0 at the top.
The default wrap mode is SCNWrapMode.clamp. See SCNWrapMode for available modes and their effects.
