If the projection of an object in sunlight is oval, then the shape of the object may be round or oval, or it may be conical.

The following does not belong to the central projection phenomenon is "AD".

A. the shadow of the needle of the sundial in the sun B. the silhouette of the characters in the shadow play

C. The shadow of the wolf's head made by hand under the desk lamp D. The slender figure in the deep alley under the moonlight

Note: Sunlight and moonlight can be approximately regarded as parallel light, and the projection under their illumination is parallel projection, while the projection of light from one point to the surrounding is the center projection. So BC is the central projection and AD is the parallel projection, so it is not the central projection.
