这是一个基于QT,C++,OpenGL的简单的渲染器。以下是它的界面

scene

目前前三个menu的按钮还需要完善(更改输入object和render模式需要在MyRender类里手动修改),第四个按钮摄像机可以调整摄像机模式。多个object一起绘制有一些难度,这里还涉及shader管理,内存管理,用户交互,有点负责,以后慢慢改了,目前把场景类写了个框架,距离真正使用还有很长距离。还有PBR也贴图也没加进去,现在只能读mtl文件的给定的参数。

目前已有的功能:

多边形PRT光照算法(siggraph2020),结果如下:

PCSS、SSAO有些参数设置问题导致绘制有点问题,图先不放了,未来会修复,目前比较忙

PCF+PBR微表面模型点光源(全方向) 见第一张图
