Camera projection mode for headless splat rendering.
pinhole — standard perspective projection with fovY as the
vertical field of view. Splats are culled by camera-space cz <= near.
equirect — full 360° × 180° equirectangular panorama from the
camera position. fovY is unused (the projection covers the entire
sphere); width must equal 2 × height (standard 2:1 panorama
aspect). Splats are culled by radial distance r <= near.
For both modes the right/down/forward basis derived from
position, target, and up defines the orientation. In equirect
mode, image-x = 0 maps to azimuth -π (behind the camera, left edge)
and image-x = width/2 maps to the forward direction; image-y = 0 is
the zenith and image-y = height is the nadir.
