A:课程直播有录像回放。我们会在课程直播后上传录像并通知给大家。通知方式包括邮件,微信群和公众号。请大家留意邮箱,微信群和公众号。Q:课程PPT会不会公开?
A:课程PPT会公开在课程主页和GAMES网站上。PPT上传后会通知给大家,通知方式包括邮件,微信群和公众号。请大家留意邮箱,微信群和公众号。Q:怎么提交作业?作业说明怎么得到?
A:作业系统的注册登录和使用方法请点击这里,作业说明会由助教在BBS上发布,并邮件通知大家,请大家留意邮箱。Q:课件PDF下载不下来?
A:由于课件PDF原链接是国外的,因此中国大陆访问速度较慢,我们为中国大陆的用户准备了百度云备份链接,在这里可以看到。Q:虚拟机运行卡顿?
A:虚拟机运行卡顿时,可以在设置中提高分配的内存和cpu核心数。This post has received 1 vote up.-

⚠️⚠️⚠️作业三常见问题集合:
(1) bump mapping 部分的 h(u,v)=texture_color(u,v).norm, 其中 u,v 是 tex_coords, w,h 是 texture 的宽度与高度
(2) rasterizer.cpp 中 v = t.toVector4()
(3) get_projection_matrix 中的 eye_fov 应该被转化为弧度制
(4) bump 与 displacement 中修改后的 normal 仍需要 normalize
(5) 可能用到的 eigen 方法:norm(), normalized(), cwiseProduct()
(6) 实现 h(u+1/w,v) 的时候要写成 h(u+1.0/w,v)
(7) 正规的凹凸纹理应该是只有一维参量的灰度图,而本课程为了框架使用的简便性而使用了一张 RGB 图作为凹凸纹理的贴图,因此需要指定一种规则将彩色投影到灰度,而我只是「恰好」选择了 norm 而已。为了确保你们的结果与我一致,我才要求你们都使用 norm 作为计算方法。
(8) bump mapping & displacement mapping 的计算的推导日后将会在光线追踪部分详细介绍,目前请按照注释实现。This post has received 1 vote up. -
