Global illumination is about, gathering photon distribution. photon distribution is largely a result of geometry and participating media, resulting in different amount of photons in volume and surface.

Is it possible to transform global illumination to a different space, which is easy to compute photon distribution, then transform the result to the 3D domain?

Is there a math model to capture the characteristics of global illumination, which is efficient to compute? 🙂

Or, what’s the characteristics of global illumination? It’s the result of light transport in participating media and surfaces.

TODO:

Understand light transport
Simplify light transport to capture essential characteristics of light transport
Understand geometry
Simplify geometry representation: is it possible to represent it in a different domain?
Understand participating media
Simplify participating media: is it possible to represent it in a different domain?

Ideas:

Grind down geometry representation to see how it looks in a different space

Light transport is observed in scientific efforts of capturing the statistics of light transport. For example, light transports in straight line is a conclusion of statistics of photon transportation. Is it possible to abstract the light transport mechanism?

Using Python 3.7 via Virtual Environment

sophie

Set up python 3.7 virtual environment:

Terminal command in home directory:

mkdir .seleniumVirtualEnvPy
python3.7 -m venv .seleniumVirtualEnvPy/python3.7

Set up alias for activating python3.7:

Terminal command:

vi ~/.bash_profile
alias activate_python3=’source ~/.seleniumVirtualEnvPy/python3.7/bin/activate’

Test activate python 3.7 with alias:

Terminal command:

source ~/.bash_profile
activate_python3

Succeeded activation of python 3.7:

Example of terminal output change:

Shens-MacBook-Pro:~ GypsyShen$ -> (python3.7) Shens-MacBook-Pro:~ GypsyShen$

MRV Fee Payment for H1B VISA Appointment at Shanghai

sophie

Problem: in the US and no debit card of China CITIC Bank to pay the MRV fee.

Solution: go for Taobao service for the payment:

Service: https://item.taobao.com/item.htm?spm=a1z09.2.0.0.51e82e8dvtC24u&id=522849435526&_u=93ef1cfd0e24
Contact: the fastest way is to communicate in the Taobao app. The messaging dialogue in web browser doesn’t always pop up
Information needed: CGI号码，护照号，名字，联系电话，邮箱，身份证号码

Note: it’s possible to create an account using US credit card, US address, and gmail. I am using Chase for the payment. The system automatically convert US dollars to RMB, so we don’t have to convert US to RMB within the US bank account, which isn’t supported by certain banks, such as Chase – the one I’m using.
