作业1勘误？

GAMES101-HW/hw1/main.cpp Line 51: float top = -tan(DEG2RAD(eye_fov/2.0f) * abs(zNear)); ①这里的括号可能是手误？应该为tan(DEG2RAD(eye_fov/2.0f)) * abs(zNear); Line 56: 0,0,(zNear+zFar)/(zNear-zFar),(2*zNear*zFar)/(zFar-zNear), ②4x4矩阵的第三行第四列，漏掉一个负号？refer to http://www.songho.ca/opengl/gl_projectionmatrix.html

pa3 displacement mapping

我认为应该把`displacement_fragment_shader`中的这段 ```cpp Vector3f n = (TBN * ln).normalized(); Vector3f p = point + n * huv * kn; ``` 根据注释修改为 ```cpp Vector3f p = point + normal * huv *...

作业6: inter.coords坐标

https://github.com/Quanwei1992/GAMES101/blob/ccaae8feeeb29a35c89651d8ed5729a186ad4226/06/Triangle.hpp#L230 inter.coords的值感觉应该是相交点在空间中的坐标 inter.coords = ray(t_tmp); 或者 inter.coords = ray.origin +ray.direction*t_temp; inter.coords = Vector3f(tnear, u, v); 的时候结果图和老师给的结果看起来是有区别的？
