Как определить ориентацию камеры? ⇐ IOS

[Гость]

I'm currently working on an application using Vuforia and I need to retrieve the camera direction from a 4x4 transformation matrix. I've already retrieved the position from the deviceMatrix.

VuMatrix44F modelView = vuMatrix44FMultiplyMatrix(renderState.viewMatrix, poseInfo.pose); VuMatrix44F deviceMatrix = vuMatrix44FInverse(modelView) ;` I used the vuMatrix44FGetPoseRot function to extract the rotation. However, the rotation values obtained by this method don't seem to match the expected behavior.

Here's the code used:

vuMatrix44FGetPoseRot(deviceMatrix, &translation, &rotationAxis, &rotationAngle); float pitch = rotationAxis.data[0]; float yaw = rotationAxis.data[1]; float roll = rotationAxis.data[2]; How do I determine the camera's orientation?

Thank you
