Disclosed is a solid depicting method which comprises obliquely disposing a semi-transparent mirror between a solid to be depicted and the position of observation by two eyes, disposing recording paper across the virtual image of the solid formed by means of the semi-transparent mirror, moving the virtual image relative to the recording paper in a direction perpendicular to the recording paper, and tracing the locus of the point of intersection between the surface of the virtual image of the solid and the recording paper.
