3d model texture map conversion method
The patent US12045926B1 outlines a method and device for converting a three-dimensional (3D) model texture map into a two-dimensional (2D) texture map. The process begins by determining a target plane using coordinates from multiple initial key points, which are boundary vertices of the 3D model's faces. For each initial key point, a corresponding key point set is obtained, including the coordinates of the initial key point and its neighboring points. The method involves calculating Laplace coordinates for each initial key point on the target plane, followed by the insertion of a texture map for each face into the target plane based on a preset algorithm and the calculated Laplace coordinates.
Further details of the method include determining projection planes and projection coordinates for the key point sets, which aid in calculating the Laplace coordinates. The process also involves obtaining global and local normal vectors, creating a rotation matrix, and applying a Laplace equation to derive the final Laplace coordinates. Additionally, the patent describes a device equipped with a memory and processor that executes the conversion program, as well as a computer-readable storage medium containing the program. This innovation aims to enhance the efficiency and accuracy of converting 3D model textures into a usable 2D format, which is essential for various applications in computer graphics and modeling.
