360° 等距柱狀全景

Create a seamless 360-degree equirectangular panorama in strict 2:1 projection, ready for VR viewers and interactive photo spheres. Render the place or scene described in the user request as a full spherical capture: keep the horizon level across the vertical center of the frame, keep vertical lines straight at the equator, and let geometry stretch progressively toward the zenith and nadir exactly as a true equirectangular projection would. Make the left and right edges continue into each other perfectly so the image wraps with no visible seam. Cover the entire sphere — sky or ceiling fills the top band, ground or floor fills the bottom band — with no black poles, no tripod, no photographer, and no stitching artifacts. Light the scene with believable, evenly exposed illumination and photorealistic detail in every direction, as if captured by a professional 360 camera. Do not add text, watermarks, borders, fisheye circles, or lens vignettes. User request: a foggy pine forest at sunrise with a dirt trail
