After lunch, I want to replicate the sketch shader I wrote for the Pencil-vs-Camera project. Additionally, I wrote a one-pass shader for dotted drawing / sketch post processing effect, which I think is more aesthetically pleasing. Dotted Drawing Demo Click on the play button in the left bottom corner of the embedded ShaderToy window below, to…

For a formal definition, according to Wikipedia, Principal component analysis (PCA) is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of…
What is P value?
P value is the probability that you are wrong if you reject the null hypothesis. or P value is the probability that you get equal or worse result if your experiment is right… or according to Wikipedia: For example, if you propose a hypothesis that Trump has more positive tweets than Hillary has, the your…

Follow-up Project After AtmoSPHERE:
AtmoSPHERE In 2015, Kent, Max and I, together with our brilliant advisor Jon, made and published a sand-art project called AtmoSPHERE. It creates beautiful visualization of Kinect path-tracing data with a lego-built, customized XY table.
