随机生成游戏建筑物的算法
2024-06-07 09:25:21
版本一
随机生成游戏建筑和导航网格。使用房屋四壁扩张生长的方式生成。.
存在的缺陷，有机会重构一下：
模型细致度不够，模板顶点数据直接通过程序生成使得算法变的复杂，扩展功能也变得复杂，可以试试将模板在3dsmax中预制导出。
建筑结构有些凌乱。
风格太少，需要多加模板。
todo在编辑器中根据设计师引导半自动生成。
版本二
先生成道路网，划分地块，再生成大厦类建筑。
存在的缺陷，有机会重构一下：
道路太直
模型细致度不够，大厦类建筑一般不适合使用预制模板，暂时使用多边形放样的形式。需要添加更多参数和功能比如生成异形艺术建筑。
需要添加点缀物品，比如路灯、树木、桥、等。关于树木的随机生成另外有一套算法，这里不再重复，当然也可以使用预制的树木。
