Virtual reality VR offers many exciting opportunities for urban planning: It allows city officials, planners, designers and citizens to immerse themselves in a virtual environment and view, discuss or modify possible development scenarios in ways that were not possible so far on regular computer screens or with physical models.

The CityEngine VR Experience is a complete solution for easily creating a premium VR application to explore your 3D city models and urban planning scenarios.

It builds on a combination of Esri CityEngine, which is used for data integration, 3D modeling and scenario development, and Epic Games UnrealEngine, which then renders the scene in real-time, controls the VR headset and its controllers, and allows for collaborative studies using multiple headsets over the network.

The experience comes as a ready-to-use and extensible Unreal Engine project template, from which CityEngine scenes can be easily imported, configured and viewed. Centrally located in the office is a table with the 3D city model placed on top. In VR, users now can intuitively interact with the 3D city model to. Compared to the existing ArcGIS VR solution for mobile headsetswhich is based on static viewpoints, the CityEngine VR Experience offers a much more dynamic experience, where users can freely move around 3D city models and interact with them.

More recent versions of CityEngine increasingly incorporate dedicated tools for urban planners, such as the visibility analysis tools in CityEngine However, CityEngine is primarily a modeling and reporting tool and not optimized for high-quality real-time rendering. What is required for urban planning applications that target a broad audience is an extensible authoring environment where additional interaction and user interface features can be added, and self-contained software applications can be built.

This is where game engines come into play since they satisfy all these requirements just mentioned. Since Unreal Engine 4. Datasmith is a workflow toolkit that streamlines import of data into Unreal Engine and reduces tedious manual import conversion tasks to a minimum. With the release of CityEngine Since then, customers have started making use of the CityEngine to UE4 workflow very quickly:.

In the past, creating interactive high-end visualizations of several hundred thousand buildings was a challenge. Now, with the new CityEngine This enables us to craft fluid, data rich, real-time rendered experiences for our clients and stakeholders. While this workflow can be used for creating a broad range of applications in UE4, it is also at the center of the CityEngine VR experience: Getting a model from CityEngine to UE4, and then embed it in an interactive planning environment with high quality rendering, and the appropriate navigation and interaction features Figure 3.

As shown in Figure 4, this happens very easily by grabbing the ring around the table for rotating and zooming or by holding the controller above the model for panning. After identifying an area of interest and viewing it from an aerial view, the users can decide to immerse themselves in the model.

This can either happen through predefined point-of-interest PoI indicators or by teleporting to any desired location. The point of being able to get right into a planning scenario is crucial to obtaining a sense of scale and to get an impression of specific views.

CityEngine supports modeling of multiple design scenarios within the same project, and these scenarios can be imported in the VR experience as well.

Users can activate a menu by tilting their controllers with a similar gesture to looking at a wristwatchand from there select, switch and compare different design scenarios Figure 5. Using the same menu, users can also change the time of day in order to inspect the effect of shadows thrown by tall buildings or by vegetation. Besides the aforementioned collaboration features, we are working on enhancing the VR experience in a number of directions: Game engines have very advanced sequencing and animation capabilities, which is a good opportunity to make the scenes more dynamic by adding pedestrians and vehicles.

Also, foliage could be animated, such as moving tree branches in the wind. Another direction is to add support for different lighting and weather conditions. Finally, we are working towards adding new interactive tools, so designs can be changed during a planning session.

Ultimately, we are seeking to create a new generation of urban planning applications which can be used by experts and non-experts.Posts Latest Activity. Page of 1. Filtered by:. Previous template Next. But I think that's for open worlds like was used in the kite demo.

How about doing a small city which would have tons of objects in it? It would seem the lighting demands would make this near impossible for UE4. Is there a way to make this work in a multiplayer environment? Tags: None. A large city is doable, depending on the camera viewpoint.

Keep in mind for FPS character viewpoint, a lot of culling will be done, so that most of the objects won't be displayed. You will want to do lots of optimizations specific to your game, of course. If you want a top down viewpoint, with number of objects the similar to the Kite Demo, then you might run into issues, but keep in mind that the Kite Demo was had a huge number of objects in the scene as well, so it is doable. Also, keep in mind that Batman: Arkham Knight was done in a modified Unreal 3, and it had a huge, destructible city.

It is quite playable. And while UE3 and UE4 are not the same codebase, you have access the the UE4 codebase to make the changes you would need to achieve the same or better than they did.

Now, multiplayer does add more headaches, especially since you haven't actually stated what type of game you want to create.

A turn based game shouldn't have any problems, nor should something along the lines of Farmville, where you could do the multiplayer aspect in a database, and not have to use the UE4 Multiplayer mode. Keep in mind something the size of the Kite Demo required lots of memory, 24GB in fact, which doesn't play well in the server environment. You would have to come up with a strategy to compensate for that.

Unfortunately, I haven't been involved in a multiplayer game project, so thats about as far as my knowledge goes. There are some great discussions in the forum about multiplayer optimizations, and requirements, so do a search, find someone that seems to know what they are talking about, and send them a PM. Comment Post Cancel. I was thinking along the lines of a multiplayer FPS, perhaps breaking the game map into tiles making it easier to create.

But I'm still not sure how the lighting would work. I guess that if the map was mostly static meshes on top of a terrain, you would eat a lot of the video ram storing the light maps. Originally posted by Whammy View Post.

Except it would be much and much more performance friendly if you were to have static lights. Sure, seven years from now when the build finishes. The enormous build time would be a very real concern. I could just see finding a small mistake that needed fixing and having to rebuild everything over again.

On the other hand, asking the dynamic lighting to deal with something that large is asking a lot from the engine. That's where not rendering at production quality right away comes in. And baking using the cloud is a thing now too I believe. EpicForum Style.More results. I'm thinking about using splines to do this, but am completely stumped. Any help or tips towards solving this problem would be great. You need to calculate a convex hull, and then you can do with it whatever you want, e.

You first have to create a point list from what you have. The points could be the actor positions, but that is not very precise. You can work with bounding boxes there too. So you have your BorderManager or something object.

There you have a function. It calculates inside points, and with the algorithm then calculates the vertices of the boundary polygon. You can save them. Everyone can query these e. Yeah, I'm looking to for the player to be able to draw really free form shapes, like even write your name in territory if you wanted to. Also, I don't think a convex hull is exactly what I'm looking for. A convex hull wouldn't be able to create the type of freeform shape I need.

You can use the example Street Map Component to render streets and buildings. Note: This plugin is a just a fun weekend project and not officially supported by Epic.

Unzip the files into a new StreetMap sub-folder under your project's Plugins folder. Load the editor. You should now see your streets and buildings in the 3D viewport. If the rebuild was successful but you don't see the new features, double check that the Street Map plugin is enabled by clicking the Settings toolbar button, then click Plugins.

Locate the Street Map plugin and make sure Enabled is checked. If you're new to plugins in UE4, you can find lots of information right here.

Well, I want to keep the benefits of mesh instancing and oclusion culling, so I don't want a huge mesh of my whole city.

I've been searching for this for the past week and I've found a couple of old threads that points to broken links of procedural. And I've also seen a couple of videos, where they use a Python script to export a t3d file. I haven't found this script anywhere, nor documentation about how a t3d file is supposed to be.

I know anything about Python either, although I've got programming knowledge. So, at the end of the day, this should be like if I'd have placed each model inside UE4 editor. I know this is possible somehow lol. Although, to me, it doesn't seems too clear right now, since I'm new to CityEngine and also to UE4 been using Unreal for a month now, although I've got some game development knowledge.

So, does anyone has a copy of this old T3D export script? Or even better, does anyone has an updated one? If not, can someone point me to some documentation about generating T3D files?

Originally posted by jwatte View Post.More results. Is it possible to identifying coordinate system for the city? Thanx again best regard. You should be able to make a sequence look as good as you have the patience for : Personally I think you could almost approach the quality seen in destruction movies like but it would take a team of skilled FX artists and modellers who are comfortable with things like destruction simulations in a 3D program.

The editor will not do this work for you. You should fairly easily be able to devise a system that randomizes an earthquake within a 2D coordinate system. Something like that could be either in blueprint or in code.

There are so many ways you could approach this. I would probably approach the bulk of the work by using regular static meshes that use Vertex shaders to animate. Then for any material where you increase Fallheight, the building will fall. You could layer on some simple sine-wave stuff and particle FX at that point, and the really big 'hero buildings' could have a custom skeletal mesh animation, but you probably would not want to do that for every single building in your scene.

So all you really need is a way of generating random numbers within a range equal to the size of your world or simply refer to it as internally and 'remap' to your level bounds and then associating the results with a group of buildings.

The vertex shader approach I like best here, since you wouldn't even need to know which buildings are close to the 'epicenter'. You would simply do the math for the 'distance threshold' within that vertex shader.

Ie, get the distance between actor position and the "epicenter" of the current quake. You could have an IF node that says "only do something IF that is less than meters. Furthermore, you could also have a staggered set of lesser destruction events.


Your method can be either incredibly basic like the vertex shader trick I mentioned, or it could be a full on custom-system where you build a City with a node based Hierarchy and propagate destruction through neighbor linkages with extra logic.

The only limit you will hit with the realtime rendering is the amount of skeletal meshes, polygons and dynamic shadows etc. But realistically all of that is manageable if you keep your assets as simple as you can ie, don't do a k poly skeletal mesh destruction animation for every single building, particle FX or vertex shaders can handle the bulk of your noisy stuff and look almost as good.

For passing the earthquake locations to all of the objects in the scene I suggest you look into Material Parameter Collections. Then just create vector parameters for as many simultaneous earthquake events you want your simulation to handle.

FYI Vectors in param collections are V4, so the first 3 components could be location and you could use the 4th for magnitude which would be convenient.
