public class VkSRTDataNV
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Structure specifying a transform in SRT decomposition.
Description

This transform decomposition consists of three elements. The first is a matrix S, consisting of a scale, shear, and translation, usually used to define the pivot point of the following rotation. This matrix is constructed from the parameters above by:

S =

sx a b pvx

0 sy c pvy

0 0 sz pvz

The rotation quaternion is defined as:

R = [ qx, qy, qz, qw ]

This is a rotation around a conceptual normalized axis [ ax, ay, az ] of amount theta such that:

[ qx, qy, qz ] = sin(theta/2) × [ ax, ay, az ]

and

qw = cos(theta/2)

Finally, the transform has a translation T constructed from the parameters above by:

T =

1 0 0 tx

0 1 0 ty

0 0 1 tz

The effective derived transform is then given by

T × R × S
