[THREEJS] scrolling 2d/3d noise terrain


Recommended Posts

Hi everyone. I've been toying around with using perlin and simplex noise to generate height values for a terrain mesh with threejs.

My aim is to create something visually similar to Populous.




So far I have something that looks like this.

At the moment I have custom plane mesh subdivided horizontally and vertically by 10. Each of the mesh's vertices y value is determined by using a noise function. This all works fine enough it seems, though I am running into issues when trying to implement a scrolling effect, again similar to Populous.

First I declare and init some variables.

//globalvar mesh_width = 10, mesh_height = 10;var tile_width = 1;var xpos = 0, zpos = 0;var x = xpos, z = zpos;//initialize terrain data arrayvar terrain_data = new Array(mesh_height);for(var i = 0; i < terrain_data.length; i++){    terrain_data[i] = new Array(mesh_width);}noise.seed(Math.random());

I then define the terrain_data object using the noise functions.

for(var j = 0; j < 10; j++){    for(var i = 0; i < 10; i++){                        var value = noise.simplex3(x, z, 0);        value *= quality;        //console.log(Math.abs(noise.simplex2(x, z)));        terrain[i][j] = Math.abs(value);        x += 1;    }z += 1;}

EDIT: This was a mis-post. I'm sorry. It can be deleted.
