暴力调整Oculus Rift的瞳距设置

A ruthless way to modify your Oculus Rift’s IPD (Interpupillary Distance)

TL;DR: Pictures say it all.

IPD (interpupillary distance) is basically the distance between the center of your two eyeballs. The average value is 63mm~65mm, which Oculus Rift DK is designed for(64mm). If yours is too wide or narrow beyond that you’ll notice how the image in Rift doesn’t focus too well horizontally, which is uncomfortable and may lead to sickness.

My IPD is extremely wide, 72mm (please, I’m still handsome). After a while’s use I knew this is not something I can just ignore so I did some research. The problem turned out to be pretty common, this post shows plastic adapters user bwhill designed to adjust the IPD to specified value. But he’s only selling 3D-printed products not sharing or selling the blueprint and it’s too much of a wait to ship to china. So I penned a few lines and plugged in my heat knife, it’s not pretty but it had the job done.

Time offset for particle instance animation in Maya

所以我觉得这应该是一个很基本的功能,动画的instance很自然的想要动作随机一些,不然效果差很多,跟做广播体操似的。上面的视频里设了3个稍微不同的开始时间,懂我意思吧。
因为instancer只是把你加入列表里的虫子模型调整位置显示,无法直接偏移时间,所以思路是copy多个虫子,逐个调整时间后把它们随机附着在粒子上。 Continue reading

Use Kinect LiDAR for camera matchmoving in PFTrack | 用Kinect的激光测距来帮助PFTrack的摄影机反求

So yea I got the idea becaues I wanted to deploy some close-up shots in my small project, but close-ups are always a pain to matchmove according to my experience. We know that this device’s resolution is quite limited, so does it work?

Couldn’t find anybody done the same thing using this low cost toy on Internet, or at least they didn’t post it. So here you go, the result turns out neat and I’m really happy with it. Notice at the end of the clip, the shot is pretty close and it worked fine. Video:

PFTrack随便弄张人脸的model摁上去track一下,10分钟就弄出上面这个,好方便。粗糙点没怎么调,“观众能吃粗粮”。
感觉对于模糊一下再偏点位置造的假影子来说.. 这个效果令人过于满意了。
技术前期又完成一个,还有我看看.. 58个events? ಠ_ಠ
