Questions tagged [terrain]

Terrain, or land relief, is the vertical and horizontal dimension of land surface. Terrain is used as a general term in physical geography, referring to the lie of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. In games, terrain is the "land" or "world" on which the game environment, roads, buildings, vehicles, characters are placed and interact with each other.

Playable Heightmap

I have a game with infinity procedually generated terrain. I'm using 1/f noise for the height (I think this is perlin noise?). Anyway it looks nice, but its not very playable since it doesn't really have flat areas. Just decreasing the amplitude…

Cesium path onto terrain: line connecting 2 points goes under the terrain

I have a path moving over time. I use Cesium.sampleTerrain to get positions elevation and drape them on the terrain. The problem is that, even if all points are on the terrain, the line connecting 2 points sometimes goes under the terrain. How can I…

What is the point of heightmaps?

I've been pondering this question awhile now... many 3d engines support advanced terrain rendering using quadtrees, LOD... all the features you expect. But every engine I've seen loads height data from heightmaps... grayscale bitmaps. I just can't…

Tiled Terrain Generation with Perlin Noise - Java

I'm currently generating 2d Perlin noise to a 2d array and (after interpolation) rendering the results held as a height map (essentially array[x][z] = y). This is fine for one array, but not for tile loading based on the camera position, and I'm…
