Fluid Engine Development
Intro From the splash of breaking waves to turbulent swirling smoke, the mathematical dynamics of fluids are varied and continue to be one of the most challenging aspects of animation. Fluid Engine Development demonstrates how to create a working fluid engine through the use of particles and grids, and even a combination of the two. Core algorithms are explained from a developer’s perspective in a
Reaction-Diffusion Tutorial
The grid is repeatedly updated using the following equations to update the concentrations of A and B in each cell, and model the behaviors described above. Some typical values used, for those interested, are: DA=1.0, DB=.5, f=.055, k=.062 (f and k vary for different patterns), and Δt=1.0. The Laplacian is performed with a 3x3 convolution with center weight -1, adjacent neighbors .2, and diagonals
NVIDIA FleX
FleX is a particle based simulation technique for real-time visual effects.Traditionally, visual effects are made using a combination of elements created using specialized solvers for rigid bodies, fluids, clothing, etc. Because FleX uses a unified particle representation for all object types, it enables new effects where different simulated substances can interact with each other seamlessly. Such
Water Simulation - DirectX 11 Competition Entry | Unity Community
It is based on a Directx 9 water simulation I made in Unity earlier, to learn about 3D rendering and shaders. This one has been completely rebuilt to use Compute Shaders, in stead of hacked together Vertex and Fragment shaders. The availability of the ComputeBuffer in Unity 4 means that it is now possible to use the high precision (floating point) height map data that is used for the terrain and w
PhysX SDK
Modeling digital twins of factories, cities, or entire worlds involves complex simulations that must accurately replicate the physical behavior of objects and systems, which are foundational in building generative physical AI for powering the next generation of autonomous systems. NVIDIA PhysX® is a scalable, multi-physics SDK for simulating and modeling physics in Robotics, Autonomous Vehicles, a
