Q3Matrix4x4_SetIdentity

You can use the Q3Matrix4x4_SetIdentity function to set a 4-by-4 matrix to the identity matrix.

TQ3Matrix4x4 *Q3Matrix4x4_SetIdentity (TQ3Matrix4x4 *matrix4x4);

matrix4x4

On exit, the 4-by-4 identity matrix.

DESCRIPTION

The Q3Matrix4x4_SetIdentity function returns, as its function result and in the matrix4x4 parameter, the 4-by-4 identity matrix.
