Procedural Dense Forest of Thousands of Trees

Using Three.js, build a detailed forest: thousands of trees, dense grass, and ferns. Use custom shaders and efficient instancing to maintain detail throughout the scene, from near to far, without performance issues. Avoid: trees arranged regularly like a plantation, distant views reduced to flat textures, performance collapse due to lack of instancing, monochromatic grass.

用 Three.js 建一片細節豐富的森林:數千棵樹、濃密的草地與蕨類。使用自訂 shader 與高效率的重複幾何(instancing),讓整個場景從近到遠都保有細節而不卡頓。避免:樹木排列規則得像人工林、遠景只剩平面貼圖、沒用 instancing 導致效能崩潰、草地顏色單一。
