<p class="MsoNormal">I’m very confused by this coordinate system. It appears that our conventional left-handed and right-handed systems are NOT used, which causes havoc with the OpenGL coordinate frame.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It seems like getting the view matrix at the origin looking down what would be a left-handed +z-axis but rotated 90-degress about the x-axis so that z is pointing up seems to be the coordinate frame.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In a function call for getting the view matrix from a camera, for example. You get these values for the matrix (assuming it’s
<b><u>column-major</u></b> order)<o:p></o:p></p>
