Three js walk on terrain

This demo uses a noise generator to generate a random terrain, and adds a whole lot of extra functionality, but we can use this concept to also render maps of real terrain. This project offers us elevation data geotagged with a resolution of 30 meters. On this site you can download tiles for specific areas after free registration :. This format contains values for specific geo coordinates. So download some tiles and make sure the form you download is a rectangle see previous screenshot.

For this I use the following very basic bash script. Each tile is x pixels and we also define the range of the input to until In other words the elevation from the input is from tot meters Since the gray scale in a PNG can only be in a range ofthis will be downsampled.

We can use other input formats, or use an RGB scale, but that would require some custom code, which is a bit out of scope for this article. For most maps though, this should be enough for a general impression of the landscape. We need to combine those to a single PNG that we can use as a heightmap for Three. In the example for Corsica we have 8 files, which are combined into a single png using the following batch file:. A couple of days ago I ran into an issue with our hosted Kafka environment, and we had to give a demo.

So I was looking for a quick way to run a simple ephem I do a lot of backend development, and there is a set of commands wh This is just a quick article on how to create a simple standalone Apollo client to test Graphql subscriptions.

I needed something like this when we ran into WebGLRenderer ; renderer. Scene ; scene. PlaneGeometry,; geometryTerrain.By Peter Liu. Mapbox builds the full mapping stack: collecting geographic data, cutting it into vector tiles, and rendering maps on many platforms.

I was able to drape the imagery over the extruded terrain and make a fully interactive 3D map to explore mountains and valleys around the world. Check it out here! Ayers Rock. Unlike similar experiments, this is not limited to pre-rendered scenes but is a true slippy map that loads new tiles as you move around.

By decoding Mapbox elevation tiles from RGB values to height in meters, we can generate a grid of elevation corresponding to every pixel in the tile. Left to right: terrain-rgb tile, Three. PlaneGeometry object, we make a three-dimensional, skeletal bump map of our tile. This way we create terrain with realistic contours and shading. Sign in.

As you can see you have different zones that make the terrain more varied, the blue zone represents water, the green one represents trees or grass and the white zone at the mountain top is snow.

Imagine your video game character walking on these 3D mountains or flying over them, pretty cool eh? You can take him through river, forest, wind and snow if you want.

Terrain is a procedural terrain generation engine for use with the Three. Terrainor install it with npm npm install three. To include it on a page client-side without a module loader:.

Terrain object. Make sure the three. The latest releases of this project have been tested with three. All parameters are optional and thoroughly documented in the source code. You can play around with some of the parameters and see what happens in the demo. Methods for generating terrain procedurally that are available by default include Cosine, Diamond-Square a better version of Midpoint DisplacementFault lines, Feature picking, Particle deposition, Perlin and Simplex noise, Value noise, Weierstrass functions, Worley noise aka Cell or Voronoi noiseBrownian motion, arbitrary curves, and various combinations of those.

Of course, the easy way to generate a heightmap if all you need is a static terrain is to use the demo and save the generated heightmap that appears in the upper-left corner. However, if you want to perform custom manipulations on the terrain first you will need to export the heightmap yourself. To import a heightmap, create a terrain as explained above, but pass the loaded heightmap image or a canvas containing a heightmap to the heightmap option for the THREE. Terrain function instead of passing a procedural generation function.

This will work just fine in general with the caveat that the exported files will be much larger than a heightmap.

Note that if you do it this way and you're using the dynamic texture generator, you'll need to re-generate the texture in code and apply it to the terrain. A utility function is provided that generates such a material other than blending textures together, it is the same as a MeshLambertMaterial.

Many other utilities are provided, for example for compositing different terrain generation methods; creating islands, cliffs, canyons, and plateaus; manually influencing the terrain's shape at different locations; different kinds of smoothing; and more.

These features are all fully documented in the source code. Additionally, you can create custom methods for generating terrain or affecting other processes.

There is also a simulation included that calculates statistics about each major procedural terrain generation method included in the THREE. Terrain library. Skip to content.

I have an object3D which is being placed on a terrain plane mesh. I create a Ray, positioned at the object but really high, and find the intersection point into the terrain essentially the Y intersection. Once I have that I position the object on the terrain at that position.

From the intersect object function I also get the Face which contains the normal at that point. What I'd like to do is align the mesh so that it has the same rotation as the point its standing on. Once the object is aligned with the world I also need it to face a target its heading towards. Currently I'm using the lookAt function to achieve this. So I guess my question is two parts.

The first is how to align the object with the world. And the second is, how to get that object to face a target without messing up the calculation of the first? I guess this could be achieved with a child node? The parent node aligned to the world and the sub-mesh node looking at the target? How are we doing? Please help us improve Stack Overflow.
