viewport_content_wires() computed view_right via world_z × view_direction (cross-product). This gives the OPPOSITE sign to the right vector that look_at_rh produces for views with a Y component (FRONT/BACK views): GPU look_at_rh: screen_right = f × up = (−vd) × (rot*Y) = rot*X Old CPU formula: screen_right = Z × vd ← opposite sign for FRONT/BACK The mismatch caused the paper-space projection to appear mirror-flipped after panning/rotating in MSPACE. Fix: use camera_for_viewport() to obtain the exact same rotation quaternion the GPU uses, then derive both axes from it: view_right = rotation * X view_up = rotation * Y Also replaces the perspective depth dot-product (mp · vd) with mp · (rotation*Z) so the depth direction is consistent too.
