Water simulation and terrain change are both important aspects in computer graphics and useful in producing realistic interactive environment. We present a step to combine the two phenomena together. In our system terrain is carefully organized to make it can be modified easily. The water flow is calculated by the shallow water simulation, which is a 2D simplification of Navier-Stocks equations. When...
We present a method to couple particle-based fluid simulation methods such as Smoothed Particle Hydrodynamics (SPH) and volume rendering in order to visualize the fluid. A volume is generated from the fluid's implicit density field so volume raycasting can be performed to render the surface on the GPU. The volume generation algorithm is also implemented in the GPU and is suitable to be used with both...
In this paper, we implement a hybrid combustion model which incorporates the fire simulation and solid burning together. To achieve real-time performance, GPU is used to solve the Navier-Stokes equations with CUDA programming, also used to visualize the turbulent fire. Experiment results prove our method's efficiency.
A low-cost excavator simulator has been developed in this paper for training human operators and evaluating control strategies for heavy-duty hydraulic machines. In such a system, the operator controls a virtual excavator by means of a joystick while experiencing realistic operating feelings through force feedback, graphical displays, and sound effects in virtual operating environments. A GPU (graphics...
