To simulate grass field swaying in wind, it is essential to establish the model of wind field. Wind is the flow of gases on a large scale, which can be modeled by Navier- Stokes differential equations or microscopic mechanism based on statistical physics. However, the computational complexity of these approaches can not be ignored.A simulation on grass swaying with dynamic wind force
May 10, 2016· In this work, we present a simple yet effective grass model that enables the real-time simulation of grass swaying mimicking real-world grass motions under dynamic wind force. We characterize each individual grass using a simple polyline model with four vertices derived from the control knots of a cubic Bezier curve describing the real grass shape.Cited by: 1A simulation on grass swaying with dynamic wind force
By utilizing the tessellation shaders and geometry shaders of modern GPUs, we make our grass model as efficient as possible so that it scales well to a large meadow, which is also exposed to a plausible wind field simulation. As a result, our grass simulation runs in real time for meadow scenes consisting of hundreds of thousands of grass blades, and produces convincing wave-like motions when the wind blowsAuthor: Yi Lo, Hung-Kuo Chu, Ruen-Rone Lee, Chun-Fa ChangDynamic Simulation of Grass Field Swaying in Wind CORE
In this paper, we propose a method for dynamic simulation of grass field swaying in wind. The representation of large-scale grassland relies on three different levels of detail that reduce the rendering cost and still allow high-fidelity rendering of grass close to the viewer.A simulation on grass swaying with dynamic wind force

In this paper, we propose a new approach to dynamic modeling and rendering of grasses wagging in wind. Through length preserving free-form deformation of the 3D skeleton lines of each grass blade...Simulation and rendering for millions of grass blades
The simulation does not stop immediately when objects leave the tile but with a smooth transition to the original GPU-instanced state. Grass motion is solved with collision, length, bending and twisting constraints. Global animation from wind is still handled through conventional, procedural methods inSimulation and rendering for millions of grass blades

Global animation from wind is still handled through conventional, procedural methods in the vertex shader. Our method is also compatible with a rendering level-of-detail LOD system. With 128 objects moving in a field with over a million blades of grass, the frame rate is less than 20 ms, with only a few milliseconds of that time for simulation.Real-time continuum grass | Request PDF
We adopt the wave simulation as the numerical model for the dynamics of continuum which represents grass-grass interaction. We propose a procedural approach to handle grass-object and grass-wind...A Novel Approach to Simulate the Interaction between
simulation of large-scale dynamic and believable grass field is still a challenging problem in the field of natural phenomena simulation with wide applications in film industry, computer games and other multimedia applications. Existing researches mainly focused on grass motion in wind field, while only a few studies have been reported on methodsGrass in Real-Time with Dynamic Lighting | Request PDF

Jul 19, 2017· The arena planners have guaranteed this with a fabulous technical trick: when no games are scheduled, the entire grass field is moved outside the stadium. The complete playing field with a total weight of 11.400 t can be moved in and out of the stadium over a distance of 300m in four hours.Grass blowing away in the wind Particles and Physics
Hi! As part of a larger animation I have a sequence with grass that is supposed to sway gently in the wind. As I am using cycles for this project, and as hair is not supported in cycles yet, I’ve used a particle system emitter to distribute grass all over a plane, which works quite nicely. I then tried making the original object (the grass straws that are being emitted by the particle system...Lattice-Based Flow Field Modeling Kent

where C is a concentration of pollutant, u is the mean wind, and K x, K y, and K z are the turbulent diffusivities in the x, y, and z directions, respectively.. These assumptions are rarely satisfied in the PBL where large inhomogeneities of turbulence and winds are observed. However, there are some reasons that can justify the use of the Gaussian models Hanna et al. 1982; Arya 1999 —they...Animating 3D vegetation in real-time using a 2D approach
In this paper, we propose a 2D approach for real-time animation of vegetation in 3D scenes, especially suitable for simulating wind effects on 3D vegetation fields with densely leaved foliage. We represent a vegetation field as view-dependent 2D billboard layers, perform a 2D harmonic motion simulation for modeling the dynamics of vegetation at the first layer closest to the viewer, and utilize this dynamicsO.A.
