Perspective

Images: 1 image (space or architecture).
Logic: Regenerates the image from a new viewpoint and focal length — like moving a “virtual camera.”

Settings panel:

Focal length: Slider maps to 5 focal lengths (mm): 16, 24, 35, 70, 135; 0–100% maps to these five.
3D rotation: 3D cube control to rotate view horizontally and vertically (two axes).
Auto focal length: “Auto analyze focal length” analyzes the image and can fill in the focal length.
Click 「执行视角变换」 (Apply perspective) to run.

Perspective template: settings modal and result (16:9 composite)

The Result area is the image transformed by the current focal length and 3D view; compare with the modal settings.
