Geometric perspective method is produced from the mathematical principle, which applies geometric perspective to the artistic expression of painting and is the combination of science and art. It mainly expresses the three-dimensional sense of an object with the help of the perspective phenomenon of near-big and far-small.
Brief introduction of geometric perspective
key element
Geometric perspective includes three elements: visual horizon, which generally refers to an imaginary line that is highly parallel to the eyes when the painter looks up. The apparent horizon determines the perspective inclination of the painted object. When the painted object is higher than the apparent horizontal line, the perspective line inclines downward, and when the painted object is lower than the apparent horizontal line, the perspective line inclines upward. The center point refers to the visual center. It is at the heart of the painter. In Parallel perspective, all perspective lines point to the center. The distance from the viewpoint to the center point is called sight distance. If the sight distance moves to both sides of the center point on the eye level, then the obtained point is the distance point.
Brief introduction of elements
Parallel perspective When one of the six faces of a cube is parallel to the painter's position, the painter sees the perspective change produced by the other face.
Angle perspective When one corner of a cube is facing the painter, all sides of the cube have perspective changes.
