之后需要生成涟漪的时候,就从前面得到的渐进式贴图中根据涟漪尺寸获取对应的数据并将之写入到涟漪贴图中,伪代码给出如下: float3ComputeRipple(float2 UV,floatCurrentTime,floatWeight){float4 Ripple=tex2D(RippleTexture,UV);Ripple.yz=Ripple.yz*2-1;// Decompress perturbationfloatDropFrac=frac(Ripple.w+Curren...
【Water Drop系列】2a – Dynamic rain and its effects 【Water Drop系列】是雨效渲染实现的整套方案的翻译总结,本文是第二篇,主要介绍降雨的基本效果的实现方法。这里是原文链接 本篇雨效渲染文章的主要参考是ATI的“Toy Shop”Demo,这个Demo曾经被Natalya Tatarchuck在很多会议上所提及。不过虽然这个demo是2005年...

The article presents, with an example of four cities of various size, a phenomenon of a drop in water consumption by the city population in Poland. The paper draws on 1995-2012 official statistics. A significant decrease in household water consumption was observed, which refers to both the tot...
It should be noted that high-precision drop shape analysis is adopted to measure the droplet contact angle24. Hence, coating of micro-post arrays surface results in a hydrophobic wetting state. Figure 2 SEM micrographs of micro-post array surface: (a) micro-post on a silicon wafer, (b) ...
This model can accurately describe the effect of ions on the structure of water, as well as the properties of NaCl solution structure, density, and diffusion coefficient. The force field equations and detailed parameters of the mW-ion model can be found in ref. 57. MD simulations are ...
JERUSALEM, Jan. 8 (Xinhua) -- Every drop of water should be used twice in order to deal with the increasingly severe shortage of water resources, said Dan Shechtman, the 2011 Nobel Prize winner in chemistry, in a recent exclusive interview with Xinhua. ...
Hysteresis effect can be seen when placing a water drop to a glass plate and tilting the plate slightly(在玻璃板上放置一滴水滴,并将玻璃板稍微倾斜,就可以看到滞后效应) 2.2.2. Free water Free water (also called gravitation water)moves through the soil voids under the force of gravity. It is...
However, this also means that mitigation of greenhouse gas emissions could have a visible effect, at least for the climate-driven part of the total future groundwater levels in Germany. Nevertheless, even for RCP2.6, decreases in all considered quantiles were found all over Germany for some ...
water loss method with measurement, either by (i) volume drawn off to replicate observed pressure drop in test period or (ii) volume pumped in to restore pressure, or b. pressure loss method. In both cases the acceptability criterion is independent of test pressure. The allowable pressure loss...
