Confessions of a researchaholic

Publishing two papers out of one submission

Filed under: Real — liyiwei @ 12:09 pm
Tags:

Co-authors and I submitted a paper with two main parts to X, a top venue in our field.
The reviews said the first part is good contribution but the second part is basically nothing, and rejected our paper.

We then revised the paper and submitted to Y, another top venue in our field.
The reviews said the exact opposite from X, but accepted our paper conditional upon the removal the first part.

So we split the paper, with the second part to Y and the first part to (the next round of) X.

Hmm do people start to submit so early for the next SIGGRAPH?
😀

Server is unavailable

Please try back later…

The SIGGRAPH server is experiencing very heavy traffic right now, and cannot service your request. Please contact sis_support@siggraph.org if you need immediate assistance. Otherwise, please try your request again shortly. Thank you.

HPRT and CVML

Filed under: Real — liyiwei @ 9:06 am

Looking at the paper titles for HPG 2017, I wonder if it can be renamed to HPRT (similar to how CVPR can be renamed to CVML).

When we have real-time ray tracing on mobile devices (the day will come), all the legacy graphics algorithms (i.e. tricks) will become obsolete.
I believe real-time RT, instead of machine learning, will be the end of traditional rendering tricks.

Open source texture synthesis

Well I guess this is long overdue; knock yourself out here.
🙂

Open source facilitates collaboration and code reuse, and propels our progress forward. I shall participate more in the future.

And then the murders began

Technical paper authors could also get into the propulsive, forward-moving action, and to provide any necessary backstory more actively.
The outcome may be more fun and less dry for readers.

Paper length

Filed under: Real — liyiwei @ 11:08 am
Tags: ,

The obsession with paper length is a legacy of printed proceedings.

What matters most is readability.
I would rather spend 1 hour reading a 20-page paper than 2 hours reading a 10-page paper.

Then follows file size: the smaller the better for storage and transmission.

Basis cases

Filed under: Real — liyiwei @ 8:38 pm
Tags: ,

Back in the good old days when I was working as a GPU architect in NVIDIA, we had suites of tests for various stages of GPU development: architecture, RTL, driver, real chips, etc.

Ogtest, consisting of tests written in OpenGL, can be applied to all stages. Each test is written to be as compact as possible, the tests are ordered from simple to complex, and collectively they cover the entire target space (e.g. all applications to run on the target GPU).

For example, the first test is to draw a flat colored triangle, the next is a textured triangle, and the next is called son-of-the-textured-triangle (with two textures instead of just one, if I remember correctly).
I then went on to add a test called daughter-of-the-textured-triangle (I am all in for gender equality) which consists of two textures but exercised a different path through the texturing and shading units (if I remember correctly).

I like to think of these as the basis test cases for the entire target space, analogous to basis vectors in linear algebra.

This applies to all research and development projects. Instead of jumping to debug full-scale applications, it can help to design a set of basis cases first. The process can clarify our thinking, and help us debug and explore algorithm/implementation issues. The basis cases can even be part of the analysis section of a research paper.
