Solved Rotation(yaw,pitch) to Quaternion for TextDisplay

[Erfinderlabyrinth]

Hi,

I want to create a Textdisplay where the Text shown in a specific direction(yaw,pitch)(z.B. 45,45).
How can I easily transform this to a Quaternion? Had Paper a Library or a method, which can it translated?

I had seen, that I can use a AxisAngle4f, but i dont understand what this do.

Asking the AI, I got following code:

public static Quaternionf yawPitchToQuaternion(float yaw, float pitch) {
        // Convert yaw and pitch to radians
        double yawRad = Math.toRadians(yaw);
        double pitchRad = Math.toRadians(pitch);

        // Create a new Quaternionf object
        Quaternionf quaternion = new Quaternionf();

        // Set the quaternion using yaw and pitch
        quaternion.rotationYXZ(yawRad, pitchRad, 0.0f);

        // Return the quaternion
        return quaternion;
    }

and this work
