wire frame representation
Technical term in computer graphics for a 3D model displayed as a network of lines and vertices.
When a 3D model is displayed as a wire frame representation, only the outlines are visible without surface shading.
ワイヤーフレーム is the more common loanword for 'wire frame' in Japanese computer graphics. 針金細工表現 is a native Japanese equivalent, less frequently used but still understood in technical contexts.
Compound of 針金 (wire), 細工 (craft, work), and 表現 (representation). The term is a direct translation of the English 'wire frame representation' used in computer graphics.
