The key of garden rockery lies in the facade viewing of space, so the facade design of rockery is the key of rockery modeling design. The facade modeling of rockery must be based on the principle of static balance. Even for the artistic beauty of rockery, there is a sense of instability in its modeling, but in structural mechanics, the static balance relationship must be obtained according to the balance distribution method, so as to achieve the internal balance in the appearance seems unstable. Specifically, the facade design of rockery should focus on "three points" such as body, surface, line and pattern.
The body refers to the body shape of the rockery. In addition to fully considering the proportional relationship between the sight distance and the volume of the rockery (ornamental scenery), in the specific facade design, the first thing is its body shape, or high or gentle, or towering or steep, and make reasonable layout and artistic treatment for its mountain top, hillside, mountain corner and other blocks, The design of this aspect can fully draw lessons from the painting method of traditional Chinese landscape painting. For the combination of multiple shapes in facade design, especially the combination of mountains, we might as well learn from the combination method of spatial triangles.
Surface refers to the flat, curved, concave, convex, virtual, real and other ornamental textures of a rockery on the spatial facade. The facade design should avoid the straightness of copper walls and iron walls, but should use the size, texture, concave convex and holes and gullies of stones to show the contrast between light and shade. As the painting theory says: "the concave part can not be seen by the sky light, and the texture of stones is dark and black; to its convex part, it can bear the sky light, not without texture, and the color is often light because of its brightness."
Line refers to the overall contour line of the whole rockery or the synthesis of local hierarchical contour lines. For example, the main mountain in the middle of Liuyuan garden shapes the distant mountain scene in Pingyuan landscape, so the horizontal undulating local level contour is adopted to coordinate with the vast and diffuse water surface. The rockery of Huanxiu mountain villa places its main peak in the front, which is set off by the left and right canyons and lower peaks. Its facade is designed into several oblique contours from low to high from the foot of the mountain to the top of the mountain. From east to west, it is like a mountain rushing, suddenly breaking into hanging rock cliffs and ending at the edge of the pool. "It seems to be at the foot of a big mountain, cutting streams and valleys" (Zhang Nanyuan's words), It is just like the rhythm and melody of music, from low to strong, ups and downs to climax.
