hey there.. can i ask a question here? i just want to know more about camera position.. i tried to integrate JPCT-ae to vuforia, but i got stuck when i want to "Setting the FOV". expecialy in these codes
QCAR::Matrix44F inverseMV = SampleMath::Matrix44FInverse(modelViewMatrix); QCAR::Matrix44F invTranspMV = SampleMath::Matrix44FTranspose(inverseMV); //Camera position float cam_x = invTranspMV.data; float cam_y = invTranspMV.data; float cam_z = invTranspMV.data; //Camera orientation axis (camera viewing direction, camera right direction and camera up direction) float cam_right_x = invTranspMV.data; float cam_right_y = invTranspMV.data; float cam_right_z = invTranspMV.data; float cam_up_x = -invTranspMV.data; float cam_up_y = -invTranspMV.data; float cam_up_z = -invTranspMV.data; float cam_dir_x = invTranspMV.data; float cam_dir_y = invTranspMV.data; float cam_dir_z = invTranspMV.data;
i explore the threads that explain this here, and i got this thread, https://developer.vuforia.com/forum/faq/technical-how-do-i-get-camera-position. i'm sorry my question maybe too silly but i really really blind what is these codes means generally? I don't know what does Camera Position means?
