![]() At the bottom of the panel, we represent the density variation by (exaggerated) variations in colour density. The absolute pressure P varies little in a sound wave: the small variations from atmospheric pressure is called the acoustic pressure, p. Notice that, for a sine wave, the maxima and minima of density correspond to zeros in y(x').įor a wave in a gas, high and low density correspond respectively to high and low pressures. Once the particles are displaced longitudinally, we see that there are regions of high and low density. We then apply these displacement to the particles, which were initially equally spaced. On the axis below, we add these displacements y, and we rotate the arrows clockwise so that positive displacement is to the right and negative to the left. As we did in Travelling Waves I, we use x for the coordinate in the stationary frame, and x' for the coordinate in a frame moving with the wave, at v to our x frame. In a longitudinal wave, we still use y(x) for the displacement, and this animation shows how that works. In that wave, as usual, y was at right angles to x. It takes time to get into the mindset of everything being asynchronous and it's definitely challenging, but it's a powerful concept.In the transverse wave, we used y(x) for the (transverse) displacement as a function. One important thing with ECS though is that there is conceptually no code that executes at startup and can immediately process data, there is only code that can process data when the data is there. If you need things the be completely done loading before you use them, you simply have to preload or wait, streaming offers you more control but nothing prevents using it like normal loading. Dust particles are especially likely to accumulate in the area of the. They are still streamed, but they come first and never unload. sound knowledge of the command language Easy Plug and is not further discussed here. In a typical game there are indeed things you'll want to have loaded all the time, but that's roughly what we have with the low res buildings and the car traffic lanes. Opened one of the buildings, moved a wall section, and it immediately paused for a few seconds to update the prefab.Ĭlick to expand.MegaCity is focused on streaming all the things (tm), so everything goes through SubScenes which can be loaded independently from each other (there's a hierarchical dependency though, each high res building section requires the corresponding low res section to be loaded first). I got the same thing and was wondering if I was doing something wrong in terms of workflow. Load times for a built version of the project are impressive. I assumed the cars were all just following pre-defined routes and was pleasantly surprised when I realised they actually reacted to me to avoid collisions! The sheer amount of detail is impressive, especially after turning up the LOD bias. The overall image quality seems hard to get right, none of the AA solutions really worked well with the environment as it is. We are thrilled to announce our new plugin - DensityDensity is an audio effect plugin that creates various layers of sounds based on the input. Got rid of that to just try and look at noise and the volumetric light effects on the spotlights are still very low quality, to the point that they would look much better with old fashioned faked light cones. I initially thought the volumetrics were splotchier than they actually are, until I realised it was a noise texture on the density volumes. Didn't check the framerate but felt smooth on a 970 at 1080p with medium settings except for LOD bias pushed up to 2.5. ![]() Performance in the editor wasn't that bad for the amount of things going on, but in a standalone build it felt very decent.
