The class slides use soft constraints to specify the vectors for "constrained faces," whereas we want you to use hard constraints for the homework. In other words, the class slides...

You can compute an LDL^T decomposition for an indefinite matrix; I'm not sure why the Eigen::SimplicialLDLT documentation implies otherwise. However, in my experience with [SuiteSparse/CHOLMOD](http://faculty.cse.tamu.edu/davis/suitesparse.html) (the high-performance factorization libraries used...

I don't understand the rotation you are describing--do you want a rotation around the axis indicated by the normal vector? Do you want a rotation aligning some other vector with...

I updated the PDF with the due date: 3/21/2017 at 11:59PM.

I can actually reproduce this problem with just an `IntSlider`, so it seems the issue is not specific to `pythreejs` after all: ```python import ipywebrtc, ipywidgets slider = ipywidgets.IntSlider() slider...

Strangely after updating to Safari 14.0 (from 13.1.2), now the `IntSlider` example works reliably, but the `pythreejs` example still is still flaky: the recorder will get stuck and I have...
