- gfx::pipeline gains bind_vec3/bind_float for passing arbitrary uniforms to shaders (used for light position/color) - scene base gains on_mouse_drag virtual hook; cuber.cpp polls left-mouse delta each frame and forwards it to the active scene - cornell_box scene: 5-wall room (red/green/white), two pre-rotated white boxes with proportions from the original paper, an unlit ceiling light panel, and a point-light Lambert shader - left-click drag orbits the camera around the scene origin; pitch is clamped to ±80° to prevent gimbal flip - key 3 / --scene cornell_box selects the scene
