Simulating High Detail Brush Painting on Mobile Devices : Using OpenGL, Data-Driven Modeling and GPU Computation

Sammanfattning: This report presents FastBrush, an advanced implementation for real time brush simulation, which achieves high detail with a large amount of bristles, and is lightweight enough to be implemented for mobile devices. The final result of this system has far higher detail than available consumer painting applications. Paintbrushes have up to a thousand bristles. Adobe Photoshop is only able to simulate up to a hundred bristles in real-time, while FastBrush is able to capture the full detail of a brush with up to a thousand bristles in real-time on mobile devices. Simple multidimensional data driven modeling is used to create a deformation table, which enables calculating the physics of the brush deformations in near constant time for the entire brush, and thus the physics calculation overhead of a large number of bristles becomes negligible. The results show that there is a large potential for use of data driven models in high detail brush simulations.
