VoxelSpace Engine Overview: A Historical Perspective on 3D Game Rendering Techniques

• Voxel Space is a 2.5D rendering technique used in early 3D games like Comanche (1992)
• Based on ray casting ideas, it uses height and color maps to represent terrain
• The algorithm draws vertical lines from the back to the front for occlusion handling
• Performance optimization includes drawing from front to back and level of detail rendering
• Links provided for web demo, introduction, personal website, and map resources

Quality:
The article provides a detailed explanation of the Voxel Space engine, its history, and technical aspects without bias or promotional content.

Openrsync is an implementation of rsync with a BSD (ISC) license, designed for use on OpenBSD and other UNIX systems. It supports a subset of rsync's command-line arguments and can be used as both a client and server.

• Written as part of the rpki-client(1) project for RPKI validation on OpenBSD.
• Funded by NetNod, IIS.SE, SUNET, and 6connect.
• Installation involves downloading, configuring, compiling, and installing using `./configure`, `make`, and `make install` commands.
• Algorithm includes sender and receiver components for managing source files and destination files respectively.
• Block exchange is the core of the algorithm, involving sharing a file list, sorting entries, and exchanging updates on files.
• Security features include OpenBSD's pledge(2) and unveil(2), as well as MD4 hash seeding with arc4random(3).
• Portability is supported across various UNIX systems like Linux (glibc and musl), FreeBSD, NetBSD, Mac OS X, and OmniOS.
