📢 libigl v2.5 released
🐍 pip install libigl
Eigen → 3.4
CGAL → 5.6
OpenGL → 4.1
CGAL and its dependencies (GMP+MPFR) compile everywhere from source via cmake
Github actions finish faster and rarely fail due to heap size

#include <autodiff/reverse/var.hpp>
template <typename T> T f(T & x)
{
// "clever" branch to avoid 0/0 at x=0
if(x == 0.0) return 1.0;
return sin(x)/x + x*(x-1.0);
}
You can do this so your long titles don't look as terrible:
\newcommand{\abbrtitle}{Clever Short Title}
\title[\abbrtitle]{\abbrtitle:\\
Long Part Causing Line Breaks in Title and Spills in Headers}

Trying out a Role-Playing Paper-Reading Seminar in the style of @colinraffel's blog colinraffel.com/blog/role-pl… in my History of Language and Computing graduate course this semester. Eager to see how it plays out, but I wanted to show off the class materials that just arrived :)
Q: We're almost out of time. Do you have any questions for me?
A: Yes, how do you represent a mesh with a slit along a single edge?
Typical. More time wrangling cmake than writing C++.
Here's an example project using both libigl and autodiff.github.io (a nice C++ library for forward and reverse automatic differentiation).

Mathematically is there any reason to think that:
f(x) = x
is different from
g(x) = / 0 if x=0
\ x if x≠ 0
?
I would think of the piecewise definition as an _implementation_ of the same function as f. Thus they're the same and consequently have the same derivative ∂f/∂x = ∂g/∂x, even at x=0.

been doing this for a while and I'm still not sure I know whether "strongly" or "enthusiastically" is better.

Our method also extends beyond NeRFs into images, too. We find that for gigapixel images, we're able to perform significantly better than JPEG at smaller file sizes- and also beats other neural methods like ACORN.
Apply!

Today at @SIGGRAPHAsia , I will be presenting a simple and robust method for transferring skin weights from rigged body meshes to any clothing meshes, thus helping automate the tedious process of manual weight painting.
