What do you mean by expanding three-dimensional graphics?

Three-dimensional graphic extension is a technology to transfer the original appearance of an object to a plane extension paper. Holographic extension, also known as three-dimensional extension, vessel extension and graphic extension, is a technology based on ink extension. It still takes China traditional ink painting as the language, China traditional rice paper as the carrier, and combines China traditional scattered perspective with western focus perspective, which artistically reproduces the shape, texture, weight, decorative patterns, figures and other contents of the objects.
