<li><strong>Camera view coordinate system</strong>
|
||||
This is the system that has its origin on the image plane and the <code>Z</code>-axis perpendicular to the image plane. In PyTorch3D, we assume that <code>+X</code> points left, and <code>+Y</code> points up and <code>+Z</code> points out from the image plane. The transformation from world to view happens after applying a rotation (<code>R</code>) and translation (<code>T</code>).</li>

<li><strong>NDC coordinate system</strong>
|
||||
This is the normalized coordinate system that confines in a volume the rendered part of the object/scene. Also known as view volume. Under the PyTorch3D convention, <code>(+1, +1, znear)</code> is the top left near corner, and <code>(-1, -1, zfar)</code> is the bottom right far corner of the volume. For non-square volumes, the side of the volume in <code>XY</code> with the smallest length ranges from <code>[-1, 1]</code> while the larger side from <code>[-s, s]</code>, where <code>s</code> is the aspect ratio and <code>s > 1</code> (larger divided by smaller side).
