GMP is an annual international conference series on geometric modeling, simulation, and computing. The modeling and processing of geometric data is fundamental to many computer applications, including computer graphics, computer vision, CAD/CAM, medical imaging, engineering analysis, robotics, additive manufacturing, and scientific computing. The GMP conference series provides researchers and practitioners with a forum for exchanging new ideas, discussing new applications, and presenting new solutions. GMP 2026 will be held in Pilsen, Czech Republic, May 27-29, 2026. Please use the LaTeX template for your submission (expected length is 10 to 15 pages).
