SSpSource_GetTransform

You can use the SSpSource_GetTransform function to get the transform matrix of a sound source.

OSStatus SSpSource_GetTransform (
SSpSourceReference inSourceReference,
TQ3Matrix4x4 *outTransform);

inSourceReference

A source reference.

outTransform

On exit, a 4-by-4 matrix that specifies the current transformation to be applied to the sound source.

function result

A result code.

DESCRIPTION

The SSpSource_GetTransform function returns, in the outTransform parameter, a 4-by-4 matrix that specifies the current transformation to be applied to the position, velocity, orientation, and up vector of the sound source specified by the inSourceReference parameter.
