Abstract
This work presents the design and implementation of a logical interaction model for liquid transfer between virtual objects within a three-dimensional interactive application. Instead of relying on continuous physical fluid simulation, the proposed approach represents liquid behavior through logical states and transfer rules. This enables control over both total volume and composition while reducing the computational complexity of the system.
The model is based on the identification of the key entities involved in the process (containers, instruments, and liquid) and is structured following a layered architecture that separates system logic, visual representation, and interaction mechanisms. This separation allowed components to be developed independently and enabled the reuse of the model in different interaction contexts. The visual representation of the liquid is derived from its logical state, showing volume and composition through changes in level and appearance within the virtual containers using shaders.
The model was implemented in an application developed with Unity and applied to a three-dimensional virtual instrument, specifically a micropipette, allowing its behavior to be evaluated in scenarios requiring precise and repeated liquid transfers. The solution was deployed both as a web application and as a virtual reality application, demonstrating its adaptability across platforms while maintaining consistent logical behavior.
