Abstract
Realism in fluid animation can be achieve with physics based techniques and is the best among other approaches. Now, this area constitutes hot researches. There are number of mechanisms evolved with the advent of both hardware and soft-ware technologies. Most of the fluid simulation methods described with or without a clear surface representation. This paper focused on a quantitative survey of various fluid surface tracking and representation techniques. Suitable tracking schemes with the hybrid fluid simulation approach may give mind blowing visual effects for various applications.
Highlights
Physics based fluid simulation is not merely a new idea in the field 3D animation
Most of the techniques in the respective area, are the numerical approximation of fundamental Naiver-Stroke equation, which has some relation with the Computational Fluid Dynamics (CFD)
The concept of metaballs is closely related to the idea of smoothed particle hydrodynamics (SPH) [17], a convention used for simulating fluids as clouds of particles
Summary
Physics based fluid simulation is not merely a new idea in the field 3D animation. Creation of fluid animation on the basis of physics laws normally called fluid simulation. Surface tracking and its representation is an attractive and enthusiastic charge field in fluid simulation. The advected surface by a general velocity field frequently changes its topology. Due to this reason, the moving surfaces are typically defined implicitly with the zero set of a scalar field rather than explicit representation of a mesh for instance. Deformable and rigid object surfaces are often represented by using an explicit triangle mesh. They are comparatively simple and efficient data structures and able to sent directly to Graphic processor units for rendering instances. Over the past few years various surface tracking methods were raised and moved on hand in hand with different fluid simulation problems.
