Vuforia camera position, model position, frustum specifications

June 15, 2015 - 2:00am #1

Hi, 

I am having trouble understanding what kind of values I can get from vuforia. 

Let's start with these two statements.

Matrix44F modelViewMatrix_Vuforia = Tool.convertPose2GLMatrix(result.getPose());
float[] modelViewMatrix = modelViewMatrix_Vuforia.getData();
 
 The translation components occupy the 13th, 14th, and 15th elements of the 16-element matrix,
 
What of the other elements? What do they represent? 
 
And the same for this statement.
 
Matrix.multiplyMM(modelViewProjection, 0, vuforiaAppSession
                .getProjectionMatrix().getData(), 0, modelViewMatrix, 0);
 
Thanks for the help.
