It’s been almost eight years since I first updated Advanced Programming in the UNIX Environment, and already so much has changed. • Before the second edition was published, The Open Group created a 2004 edition of the Single UNIX Specification, folding in the changes from two sets of corrigenda. In 2008, The Open Group created a new version of the Single UNIX Specification, updating the base definitions, adding new interfaces, and removing obsolete ones. This was called the 2008 version of POSIX.1, which included version 7 of the Base Specification and was published in 2009. In 2010, this was bundled with an updated curses interface and reissued as version 4 of the Single UNIX Specification. • Versions 10.5, 10.6, and 10.8 of the Mac OS X operating system, running on Intel processors, have been certified to be UNIX® systems by The Open Group. • Apple Computer discontinued development of Mac OS X for the PowerPC platform. From Release 10.6 (Snow Leopard) onward, new operating system versions are released for the x86 platform only. • The Solaris operating system was released in open source form to try to compete with the popularity of the open source model followed by FreeBSD, Linux, and Mac OS X. After Oracle Corporation bought Sun Microsystems in 2010, it discontinued the development of OpenSolaris. Instead, the Solaris community formed the Illumos project to continue open source development based on OpenSolaris. For more information, see http://www.illumos.org.

Unity Shader实现水体的环境映射，可以直接导入运行的工程

Enviro - The complete dynamic AAA sky and weather solution! Very easy setup: The new manager component makes it easy as possible to setup enviro in your scenes. Includes Enviro Lite! This version includes Enviro Lite version aswell. Ideal for multi-platform projects: Use lite version for low end platform like mobiles and standard for pc and consoles. With one click you can switch between enviro versions. The centralized API for your own scripts will work for both versions of course. Profile System: Enviro's new profile system makes tweaking your sky as easy as possible. Tweak settings in runtime and save to profile. Load profiles in design and runtime. Create different profiles for different scenes or share your configurations with other user. Day-Night cycle: Enviro supports a realistic day-night cycle. With correct sun and moon positions with full location support with latitude and longitude. You have options to use your system time or let enviro update time based on realtime minutes. Skybox: Enviro includes an advanced fast atmospheric skybox shader to get great looking skies! You got a lot of options to tweak the sky and even can setup funky alien skies! Lighting: Enviro will realisticly light your scene based on sun altitude. You have complete control over light intensity and color by modifying curves and gradients right in editor! You also can choose between different ambient light modes of course. Seasons: Enviro will change seasons and got a components to swap out gameobject, materials and textures of unity terrain. You are not limited to realistic settings! You can set the start and end days of each season. Enviro also supports temperature simulation, based on season, time of day and current weather. Clouds: Enviro new raymarching cloud system is based on latest cloud rendering papers. These will bring you sky to life and offer plenty options to customize. Clouds performance is optimized by using techs like temporal reprojection and LOD system. In addition there are also fast flat and particle clouds options to mix or use for maximum performance. Fog: Need stunnishing looking fog? Enviro includes an advanced light scattering fog image effect with distance, height and sky fog support. Need fog on your transparent material? No problem, with only a few lines of code you could modify your own transparent shaders to be fogged correctly. And a few particle and transparent shaders already included to get you started! Weather: Enviro includes a very powerfull weather system. You can create your own weather types and drive light, sky, fog and clouds. Enviro supports all kind of unity shuriken particle effects to give you the freedom to create any weather effect you can think of. It includes 11 premade weather types including: Clear Sky, cloudy, raining, stormy, snowy and foggy weather. You can enable lightning storms and choose different ambient and weather sounds for each weather with smooth transitions. Volumetric Lighting: Need some volume light effects you see in AAA games? No problem, enviro support volumetric lighting for directional, point and spot lights out of the box! Scene View Effects: Preview enviro effects like clouds, volume lighting and fog directly while you work on your scenes. You can enable or disable scene view preview for each effect individual of course. Networking: Enviro support UNet, Mirror and Photon out of the box. It will synchronize time and weather with all your players. Enviro also got an minimal mode for headless servers to only calculate time and weather but nothing more. Virtual Reality: Enviro supports multi and singlepass stereoscopic rendering! Tested on Oculus Rift. That's not all! Enviro includes a lot more great features: * Event system for you game logic. * Weather Zones. Create as many zones with their own weather for your biomes. * Orbiting satellites. * Vegetation Growth. And you can use a lot of awesome 3rd-party assets right of the box. Activate and add 3rd-party support through the new interface. Again its easy and fast as possible! * Gaia Compatible! * CTS Compatible! * AQUAS Integration! * LUX Water Integration! * FogVolume 3 Integration! * Vegetation Studio Pro Integration! * Playmaker Actions! * Relief Terrain Shader Integration! * UBER Shader Integration! * MicroSplat Integration! * MegaSplat Shader Integration! * Lux Shader Integration! * Photon Network Integration! * Mirror Network Integration! * Pegasus Integration! Requirements: * Support gamma and linear color space. * Support forward and deferred rendering. * Working on DX9, DX11, DX12, OpenGlCore, Metal and Vulkan. * Volumetric Lighting requires at least shader-model 3.5+ and will be deactivated on DX9 Current limitation: * Volumetric clouds are currently not suitable for fly-throughs! Will be worked on in later updates!
