  • Patent number: 10403038
    Abstract: A 3D geometry enhancement method and an apparatus therefor. A random forest regressor is built using sketch patches and displacement patches, wherein the displacement patches are patches corresponding to the sketch patches and placing on a displacement map of a 3D geometry model. A new sketch is received. Displacement patches respectively corresponding to sketch patches are extracted by applying the sketch patches extracted from the new sketch to the built random forest regressor. A displacement map with respect to a 3D geometry model is generated using the extracted displacement patches. The generated displacement map is applied to the 3D geometry model.

  • Patent number: 9880425
    Abstract: A smart window, and production method therefor, uses glass beads made from glass material instead of a polymer matrix of the conventional smart window. This makes the liquid crystal's size, shape and arrangement constant by placing the liquid crystal outside the glass beads, thereby securing high stability and chemical resistance, avoiding haze, having low operating voltage, and having improved optical, for example, broad variable range of light transmittance between OFF (light impermeable) and ON (light permeable) states.

  • Patent number: 9733467
    Abstract: A smart glass uses a guided self-assembled photonic crystal, including a photonic crystal layer that is interposed between a pair of conductive glass plates. The smart glass includes a first material and a second material having a different refractive index from the first material and surrounding the first material. Thereby, the smart glass has a color, even when a dye is not included, by strongly reflecting light in a specific wavelength range incident to the photonic crystal layer. This is because the first material is formed regularly to have a constant distance by guided self-assembly, and the smart glass thereby may obtain a target color by randomly adjusting the distance between the first materials.
