cgcenter's Introduction

CGCenter

a compute graphics learning & coding center

纸上得来终觉浅,绝知此事要躬行。

这是一个使用opengl实现的渲染器,用来实践学到的图形学知识。当前该项目刚刚开工,只是有一些规划中要实现的东西,可能会根据时间以及未来的兴趣爱好改变 实现内容,希望能够坚持下去(一个flag)

另外自己家2023年也要交付装修了,希望能在2023年前能实现一个简单的家装系统。

目前规划中要实现的效果如下:

下一步需要做的:

添加transform component

texture的格式设置

program的uniform和mesh的draw解耦

解耦std的map和智能指针

光线追踪和GI

引擎基本功能:

  • 加载模型
    • obj
  • 摄像机
    • 可漫游摄像机
  • 几何体
    • 平面 Plane
    • 三角网格 TriMesh
    • 天空盒
  • 材质
    • 镜子 Mirror
    • 漫反射 Diffuse
  • 光源
    • 点光源 pointLight
    • 面光源 AreaLight
    • 直接光 DirectionalLight
    • 聚光灯 SpotLight
  • 渲染管线
    • 正向渲染 forward rendering
    • 延迟渲染 deferred rendering
    • 延迟光照 deferred lighting、light pre-pass
    • 延迟贴图 deferred texture
  • 拾取功能
  • 重构成ECS

阴影 Shadow
