Hinweis: Beginnend mit dem nächsten Release (GitLab 17.7) wird OpenSSL 3 verwendet. Alle TLS-Verbindungen erfordern TLS 1.2 oder höher. Schwächere Chiffren werden nicht mehr unterstützt. Die Verschlüsselung muss mindestens eine Sicherheit von 112 Bit aufweisen. // Starting with the next release (GitLab 17.7), OpenSSL 3 will be used. All TLS connections require TLS 1.2 or higher. Weaker ciphers are no longer supported. Encryption must have at least of 112 bits of security. https://docs.gitlab.com/ee/update/versions/gitlab_17_changes.html#1770

Marco Wegener requested to merge feature/ambisonics_rotation_renderer into develop Sep 29, 2023

Work done until now on AmbisonicsRotationRenderer:

Added function vCreateRotationMatrix to assemble 3x3 rotation matrix from view-up vectors
Added function vFCreateSphericalHarmonicsRotationMatrix to calculate SH matrix using SAFs getSHrotMtxReal function
Added function vApplySphericalHarmonicsRotation to apply rotation to signal

All functions are stored in Utils/VASphericalHarmonicsRotation.h.

Unit tests:

Test for vCreateRotationMatrix compares matrices to reference values calculated by hand
Test for vfCreateSphericalHarmonicsRotationMatrix compares matrices to reference values calculated by Matlabs getSHrotMtx function

##To-Do:

Finish vApplySphericalHarmonicsRotation and create test. Idea: apply dirac-impulse as input signal and compare output channels
Fix compile errors caused by SAF implementation
