Abstract: We present an interactive system for ink splattering, a form of abstract arts that artists drip or pour inks onto the canvas. The user interface and interactive methods are designed to be analogous to the artsitic techniques of ink splattering in real world so that digital artists can easily create the vibrant patterns of splattering ink, which are otherwise difficult to achieve in image editing software. The core of our system is a novel three-stage ink splattering framework that simulates the physical-based interaction of ink with different mediums including brush heads, air and paper. We implemented the physical engine using CUDA and the whole simulation process runs in real-time.
