Hey all,
I’m trying to create tiled grid mesh I can use to map a level from Tiled map editor onto a procedurally generated mesh. Are there any example projects or docs or ideas people could point me towards to help me do this?
Here is an example on how to create procedural meshes:
https://developer.playcanvas.com/en/tutorials/terrain-generation/
And also in the engine there is a class that does something similar to produce some standard meshes like box, sphere, plane etc.
/**
* @function
* @name pc.calculateNormals
* @description Generates normal information from the specified positions and
* triangle indices. See {@link pc.createMesh}.
* @param {number[]} positions - An array of 3-dimensional vertex positions.
* @param {number[]} indices - An array of triangle indices.
* @returns {number[]} An array of 3-dimensional vertex normals.
* @example
* var normals = pc.calculateNormals(positions, indices);
* var tangents = pc.calculateTangents(positions, normals, uvs, indices);
* var mesh = pc.createMesh(positions, normals, tangents, uvs, indices);
*/
var primitiveUv1Padding = 4.0 / 64;
var primitiveUv1PaddingScale = 1.0 - primitiveUv1Padding * 2;
pc.calculateNormals = function (positions, indices) {
var triangleCount = indices.length / 3;
var vertexCount = positions.length / 3;
show original
Hope this is helpful to get you started.
