INTRODUCTION

English translation pending.

CORE DEFINITION

Voxel representation models a three-dimensional object or space as a dense grid of small cubes called voxels, each storing a value such as density, material, or occupancy. It turns continuous three-dimensional space into discrete data that a computer can store, render, and simulate, and it captures internal structure that surface meshes cannot express.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Digitize 3D space: convert a continuous volume into a regular array a machine can process - Store interiors: keep density, material, or occupancy per cell instead of only a shell - Resolution trade-off: choose voxel size knowing precision scales memory by the cube

Anchor fast decisions

Continuous space is divided into a uniform grid, and each cell holds one scalar value, so any shape and its interior become a queryable array. This regularity makes rendering, simulation, and geometry extraction straightforward, but memory grows with the cube of the resolution, so precision always costs storage.

Zero-Knowledge Proof

In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true, without conveying any information apart from the fact that the statement is indeed true. Thus, it can be understood as a 'zero-leakage proof'.

Batching

A batch file is a script file in DOS, OS/2, and Microsoft Windows, used as a scripting language to run programs. It is a text file containing a series of commands to be read and executed by an interpreter with a command-line interface. It is applied in DOS and Windows systems, interpreted and run by the built-in interpreter (usually COMMAND.COM or CMD.EXE). It is equivalent to a shell script in Unix-like systems. In DOS and Windows 9x operating system families, the file extension for batch files is .bat. In OS/2 and Windows NT families, the .cmd extension is added. In other operating systems, batch files may have different extensions, for example, 4OS, 4OS2, and 4NT use the .btm extension. When a batch file is executed, the shell program reads the file content and then executes its commands, typically line by line.

Head-of-Line Blocking

Head-of-line blocking (HOL blocking) is a performance-limiting phenomenon in computer networking. It occurs when the first packet in a queue (the head) is blocked, causing the entire queue of packets to be blocked. This can happen in switches with buffered inputs, due to out-of-order transmission, or in HTTP pipelining with multiple requests.
