0-3 seconds (tonearm movement): @Image1 The tonearm moves from its initial position along a single, defined arc, without pauses, pullbacks, or tentative swings. Target positioning: The sole moving target of the cartridge tip (white cassette unit) is the geometric center of the triangular sandwich—the center of gravity formed by the lines connecting the three vertices of the sandwich. This point is also horizontally aligned with or very close to the center of the black turntable. The tonearm moves smoothly along the arc, moving directly from the right tonearm support towards the center of gravity of the sandwich in the center of the image. The path is clear, the target is well-defined, and the speed is uniform and smooth. After reaching directly above the target point, the cartridge descends slowly and vertically for the final 0.5 seconds. The vertical descent point precisely aligns with the center area of the sandwich surface (directly above the geometric center of the triangle), with a slight pause at the moment of contact (simulating the force of a real stylus falling). Key constraints: The final stationary position of the cartridge must coincide with the geometric center of the sandwich, with an error approaching zero. Precise positioning must be achieved in one go, without any deviation to the edges of the sandwich, vertices, or the turntable. 3-8 seconds (rotation process): The black turntable starts from a standstill and smoothly transitions to uniform rotation with acceleration (simulating a real vinyl record at 33 rpm), with the rotation axis precisely coinciding with the turntable's geometric center; The sandwich remains rigidly connected to the turntable, rotating as a single unit. The sandwich's center of gravity always coincides with the turntable's rotation axis. During rotation, the sandwich does not experience displacement, eccentricity, deformation, stretching, or twisting, maintaining its initial triangular shape, volume, and position; The cartridge remains fixed in contact with the sandwich's center point, producing a realistic stylus tracking effect as the sandwich rotates (the cartridge slightly moves up and down following the texture of the food surface). (Simulating the physical feedback of a real stylus reading an uneven surface), but the cartridge's horizontal position remains locked at the geometric center of the sandwich, without any lateral slippage or offset; the light and shadow change naturally with the rotation angle, and the highlight positions on the sandwich surface move with the rotation trajectory (simulating the light and shadow patterns of an object rotating under a real light source). The edges of the turntable and the sandwich rotate synchronously at the same speed, without relative slippage, visual ghosting, or blurring; the camera angle remains fixed, the background remains still, and only the turntable and sandwich rotate around the same central axis, presenting a smooth, stable, and realistic mechanical rotation texture, similar to the effect of a real vinyl record player.
