I have no idea what you are talking about, but I’m curious.

The popular explanation is that it only opens for the pure of heart, but that was a myth spread by a group of the first people to successfully open The Box to big themselves up. A lot of people still believe this though, and many aspiring Boxcavators (as you know, this is the term for people who open The Box) waste their time doing things like volunteering for charities in an attempt to make themselves more pure of heart.

We don't know for sure but the current best explanation we have is that it's got something to do with how many times you thought about shrews prior to your 15th birthday, but it's proving difficult to experiment on because when people have been instructed to think a lot about shrews we can't be sure if it's multiple thoughts, or if continuously thinking about shrews counts as just one single long thought.

not much whats churbis matrix with u

wow... so cool....

This is one I'm happy to help with :D

It started way before GPUs were ever made. Reproductions of 'master works' were used by students of art.

Caballero Chubin (yes, that was her name) was one of the first to comodify this, way before the printing press. She would cut the master work into square sections, each to be reproduced independently by students, to then be stitched together and resold as a replication.

Notably, Chubin's Grid it was not a simple grid, but rather, semantic "sections". E.g. She would make sure there was no boundary over Mona Lisa's face, and have the same artist depict the whole section.

Chubin maintained an index of who worked on which section.

Cutting into sections enabled rapid production of a single reproduction, but also allowed reproductions of part of a whole work (say, of only Lubbert Das's gaunt visage) to be made and sold.

This same concept was applied to early computer graphics. Tiling is used by modern renderers, but the Chubris matrix (a portmanteau of Chubin and a developer known only as "Vris") intelligently used larger tiles for less-complicated and less-important scenes.

The "Chubris matrix" is not the grid itself, but rather, an optimal way to define and index sections of the grid. (This was when every byte mattered, remember).

The indexing was used as the inspiration for foveated rendering for VR, but also as the inspiration for PNG's compression algorithm, and more.

TLDR: It defines a non-uniform grid which is very useful for rendering.
