Assignment 2: Position-Based Fluids
ثبت نشده
چکیده
Fluid simulation is a common challenge in computer graphics, and one that illustrates the need for efficient physical models. While physically accurate simulations of fluid dynamics can be conducted by solving the Navier-Stokes equations exactly, this is computationally expensive in general, and as such is often not suitable for graphics applications, especially those that are meant to run in real time.

Fast simulation of viscous fluids with elasticity and thermal conductivity using position-based dynamics
Viscous fluids are ubiquitous, and reproducing their damped motions has been in demand for many applications. The most prevalent approach to simulating viscous fluids is based on the Navier-Stokes equations and necessitates viscosity integration. However, to simulate viscous fluids in a numerically stable manner, using explicit viscosity integration severely restricts time steps and requires an...
متن کاملAn Interval Assignment Problem with Multiple Attributes: A DEA-Based Approach
One of the basic combinatorial optimization problems is the assignment problem that deals with assigning jobs to individuals. In traditional assignment problems, n jobs usually assign to n individuals such that the total cost is minimized or the total profit is maximized. However, in numerous real-life applications, various attributes could be considered in assignment problems while data (obj...

متن کاملAdaptive Position-Based Fluids: Improving Performance of Fluid Simulations for Real-Time Applications
The Position Based Fluids (PBF) method is a state-of-the-art approach for fluid simulations in the context of real-time applications like games. It uses an iterative solver concept that tries to maintain a constant fluid density (incompressibility) to realize incompressible fluids like water. However, larger fluid volumes that consist of several hundred thousand particles (e.g. for the simulati...
