How Is the Texture of Bionic GRC Shapes Achieved?

Texture reproduction in biomimetic GRC shapes is a combination of art and technology. Through three technologies—digital acquisition, precision mold engraving, and surface treatment—Qinglong Group achieves a texture simulation fidelity of over 95%. In the Hainan Changying Universal 100 Park project, natural textures such as wood, stone, and plants were successfully replicated.

Digital acquisition captures the original texture. A 3D scanner is used to obtain surface data of natural objects with a resolution of up to 0.1mm. In the Shanghai Century Plaza project, Qinglong Group scanned real wood surfaces and acquired over 10 million points of point cloud data. Through parametric processing, the texture direction and density are optimized to adapt to the curved surfaces of GRC shapes.

Mold engraving achieves precise replication. Five-axis engraving machines process molds with tool diameters of 0.5-2mm to create fine textures. In the Wuhan Han Show Theater project, stone-pattern molds with a surface roughness of Ra=3.2-6.3μm were used to perfectly reproduce the natural texture. Special textures employ silicone mold transfer for stronger detail expression.

Surface treatment enhances realism. A multi-layer spray coating process is adopted: base color + main color + protective layer. In its wood-grain imitation projects, Qinglong Group achieved the color variation and texture layering of wood through 7 spray coating procedures. Surface aging treatment adds traces of use, enhancing artistic appeal. This refined craftsmanship makes GRC biomimetic shapes indistinguishable from the real thing.
