A Go port of the RTIN terrain mesh generator mapbox/martini by mourner. Additional info on martini can be found at the Observable notebook, "MARTINI: Real-Time RTIN Terrain Mesh", written by mourner. Original algorithm based on the paper "Right-Triangulated Irregular Networks" by Will Evans et. al. (1997).

// set up mesh generator for a certain 2^k+1 grid size const martini = new Martini (257); // generate RTIN hierarchy from terrain data (an array of size^2 length) const tile = martini. …

A Cython port of Martini for fast RTIN terrain mesh generation, 2-3x faster than Martini in Node. The only dependency is Numpy. A wireframe rendering of the Grand Canyon.

2024年8月28日 · MARTINI基于1997年Will Evans等人提出的RTIN（右三角不规则网络）理论，并加以改良。 它通过高效的算法，确保了即使在高分辨率的地形数据上也能迅速计算，实现在毫秒级内构建出地形的三角网格。

2019年9月20日 · 这基于一篇已有 22 年历史的论文 —— Right-Triangulated Irregular Networks（RTIN）。 我们进行了算法的改进，并称其为 MARTINI - Mapbox’s Awesome Right-Triangulated Irregular Networks。

2024年5月19日 · martini A JavaScript library for real-time RTIN terrain mesh generation 项目地址:https://gitcode.com/gh_mirrors/mar/martini. 1、项目介绍. MARTINI是Mapbox推出的实验性JavaScript库，全称是Mapbox的出色右三角不规则网络，改进版（Mapbox's Awesome Right-Triangulated Irregular Networks, Improved）。它的核心 ...

2024年11月20日 · What is Right-Triangulated Irregular Networks (RTIN)? This algorithm is used to efficiently render terrain. Each tile and its terrain are represented as squares.

2024年11月26日 · 本文件集涉及的地形四叉树(quadtree)和RTIN（Run-Time Incremental Node）技术是实现这一目标的关键技术手段。 四叉树作为一种有效的数据结构，常被用于管理二维空间数据，而将其应用在地形渲染中，可以极大地优化计算资源和内存消耗，实现地形的渐进式 …

2023年10月26日 · To render terrain in 3D, you need a triangular mesh — a set of 3D triangles representing the surface. The easiest way to get one from height data is a uniform grid (two triangles per pixel), but that's a lot of triangles. For fast rendering, we want to reduce this amount by adapting the mesh to the surface — using bigger triangles in relatively smooth areas, and smaller ones where ...
