Time and Location

时间及地点

Various times of day have completely different lighting moods. 一天中的不同时段有着完全不同的照明情绪

Since the position of the stars (as well as your position on the earth’s surface) lies in direct correlation to time zones, you select a set time and date for your simulation. Of course both of these properties can be animated, although there are some specifics you should be aware of (see below).

由于恒星的位置(以及你在地球表面上的位置)与时区直接相关，你可以选择一个设定的时间和日期进行模拟。当然，这两个属性都可以是动画的，但是有一些细节您应该注意(见下面)。

Tip: 提示:
 Note that shadows cast by a sun light source are only a simulation of real-world conditions, i.e., they can differ from real-world shadows and are not suited for precise simulations. 请注意，由太阳光源投射的阴影只是对真实世界条件的模拟，也就是说，它们可能与真实世界的阴影不同，不适合于精确的模拟

Sky’s internal sun will change color according to the time of day.

天空中的太阳会随着时间的变化而改变颜色。

Time

时间

This is where you enter the time and date of your Sky simulation. Click on Now or Today to set your scene to the actual date and time on your computer.

这就是你输入天空模拟的时间和日期的地方。点击现在或今天，设置您的场景到实际的日期和时间在您的计算机上。

The mouse scroll wheel can be used to scroll through the days in the calendar. Simultaneously pressing the Shift key will let you scroll through the months.

鼠标滚轮可以用来滚动日历中的日子。同时按下 Shift 键可以让你滚动几个月。

You can change the time minute by minute by placing the cursor over the clock face and scrolling with the mouse wheel or by clicking and dragging the mouse up or down. Simultaneously pressing the Shift will let you change the hours. Alternatively you can click on the single or double arrows above the clock face to set the time in minutes or hours.

您可以通过将光标放在时钟面上并用鼠标滚轮滚动，或者通过单击并向上或向下拖动鼠标来逐分钟地改变时间。同时按下 Shift 键可以让你改变时间。或者你也可以点击钟面上方的单箭头或双箭头来设置时间，单位为分钟或小时。

Numbers can be entered manually into the (time)data entry fields:

数字可以手动输入到(时间)数据输入字段:

Atomic clocks are used to calculate the UTC (Coordinated Universal Time). 原子钟用于计算 UTC (协调世界时时间)

If the Time setting’s sub-channels can be displayed, the time of day and day will be displayed numerically. Days will be displayed as continuous number (start at 0=01/01/1970), time will be displayed as a float comma between 0 (= midnight) and 1(= noon the foillowing day).

如果时间设置的子信道可以显示，一天的时间和数字将显示。天数将显示为连续数字(从0 = 01/01/1970开始) ，时间将显示为介于0(= 午夜)和1(= 正午之间的浮点逗号)。

Current Time

当前时间

When active, this option will set the scene to the current time.

当激活时，此选项将场景设置为当前时间。

When a scene is saved with the 当一个场景被保存为Current Time 当前时间 option active, the time at which the scene was saved will not be saved with the scene. When this scene is again opened, the current time from the computer’s operating system on which the file is opened will be used. If you render an animation over a longer period of time, you will notice that the current time (and position of the sun and of the stars) will be referenced. 选项激活，保存现场的时间不会随现场一起保存。当此场景再次打开时，将使用打开文件的计算机操作系统的当前时间。如果在更长的时间内渲染动画，您将注意到当前的时间(以及太阳和星星的位置)将被引用 If 如果Current Time 当前时间 and 及Today 今天 are both active, these times will also be referenced when rendering. Even an animation track for 都是活动的，这些时间也将在渲染时引用。甚至一个动画轨道Time 时间 would be ignored. 都会被忽略

Today

今天

If this option is active, the current date will always be used. The same applies here as with Current Time; the time and date at which the file was originally saved will not be saved with the file. When the file is opened again, the current time and date, in this case today, will be assumed.

如果此选项处于活动状态，则始终使用当前日期。同样的情况也适用于 Current Time; 文件最初保存的时间和日期将不会与文件一起保存。当文件再次打开时，将假定当前的时间和日期(在本例中是今天)。

If neither option is active, no interpolation between time keys will take place.

如果两个选项都不激活，则不会在时间键之间进行插值。

Let's say you have two time keys, the first with a value of 22.07 08:54, the second with a value of 26.09 18:54. If you were to interpolate these two values it would be impossible to estimate how long this interpolation would take.

假设您有两个时间键，第一个值为22.0708:54，第二个值为26.0918:54。如果要插值这两个值，就不可能估计这个插值需要多长时间。

This is why both options have the following function, respectively:

这就是为什么这两个选项分别具有以下功能:

A note for time zones that use Daylight Saving Time: If your animation takes place during the switch to Daylight Saving Time, a 使用夏时制时区的注意事项: 如果你的动画在切换到夏时制时发生,jump 跳 in your animation will take place. 在你的动画将发生

City[-2147483648..2147483647]

城市[-2147483648. . 2147483647]

Click here to access the list of available cities, organized according to country and continent. Select a city that lies near the location of the city where you want your simulation to take place. Once a city has been selected, all Location parameters will be set accordingly.

点击这里查看按国家和大陆组织的可用城市列表。选择一个位于您希望进行模拟的城市附近的城市。一旦选择了一个城市，所有的位置参数将相应地设置。

Latitude[-90..90°]
Longitude[-180..180°]

经度[-90. . 90 ° ]

Enter the latitudinal and longitudinal coordinates of the location from which your simulation should take place. The ’ and ’’ fields represent the interim values for latitude and longitude, also known as the arc minute and arcsec. Don’t hesitate to enter 0 for each value if you don’t know the exact position, or if a sextant is not readily available. If 0 is entered, expect slight deviations in a constellation’s position. This also applies if you simply select the name of a city in the vicinity of the location where your simulation should take place from the drop-down menu.

输入模拟应该发生的位置的纬度和经度坐标。和字段表示经纬度的临时值，也称为弧分和弧秒。如果你不知道确切的位置，或者六分仪不容易获得，不要犹豫为每个值输入0。如果输入0，预计星座的位置会有轻微的偏差。如果您只是简单地从下拉菜单中选择模拟应该发生的位置附近的城市名称，那么这也适用。

A comprehensive online listing of global coordinates can be found online.

在网上可以找到全球坐标的全面在线清单。

Time Zone

时区

Leave Time set to Custom. If OS is selected, your computer’s operating system’s current date and time will be used. This can lead to unwanted results. For example, a scene that was saved for London, high noon, will be pitch black (night) when opened in Sydney with the OS option on.

时间设置为自定义。如果选择了 OS，将使用计算机操作系统的当前日期和时间。这可能导致不必要的结果。例如，为伦敦保存的一个场景，正午时分，当在悉尼打开操作系统选项时，将是漆黑一片(夜晚)。

Only if Time is set to Custom will the following three options be made available: Daylight Savings, Time Zone and DS Time Zone.

只有当时间设置为自定义时，才会提供以下三个选项: 夏令时、时区和 DS 时区。

Daylight Saving

夏令时

This is where you enter the Daylight Saving Time of your present location or the location where your simulation will take place. For, among others, the United States/Canada, for example, you would select First April Sunday to Last Oct. Sunday or the second Sunday in March to the first Sunday in November. The two lower Daylight Saving Times apply to the southern hemisphere. You can find more information on Daylight Saving Time at

这是你输入你当前位置的夏时制或者你的模拟将要发生的位置的地方。例如，对于美国/加拿大，您可以选择从4月1日星期日到去年10月1日。从三月的第二个星期日到十一月的第一个星期日。两个较低的夏时制时间适用于南半球。你可以在夏时制上找到更多的信息

www.worldtimezone.com/daylight.html.

If your animation must run through the date on which Daylight Saving Time takes place, you should turn Daylight Saving to Off, otherwise your animation will jump during the time change.

如果你的动画必须在夏时制时间发生的日期运行，你应该把夏令时关闭，否则你的动画将在时间变化期间跳转。

Time Zone Diff.[-∞..+∞]
DS Time Zone[-∞..+∞]

时区差异. [-∞ . . + ∞] DS 时区[-∞ . . + ∞]

Use Time Zone to enter the difference in hours to GMT (Greenwich Mean Time – 0° longitudinal). DS Time Zone must take into account Daylight Saving Time, i.e., the United States East Coast’s Time Zone would be -5, and its DS Time Zone would be -4.

使用时区输入到格林尼治标准时间的小时差(格林尼治平时-0 ° 纵向)。时区必须考虑夏时制，即美国东海岸的时区是 -5，而它的 DS 时区是 -4。

You can find the difference for each region of the world at www.worldtimezone.com.

你可以在 www.worldtimezone.com 上找到世界各地区的差异。

Note that the regions to the West of GMT have a negative value.

请注意，格林尼治标准时间以西的地区具有负值。

Example: Let’s assume Chicago is not on the list of cities provided by Cinema 4D, but you want to render a skyscraper in Chicago using the current position of the sun. The GMT in the State of Illinois is -6; simply set Time Zone to -6.

例如: 假设芝加哥不在 Cinema 4D 提供的城市列表中，但是你想使用当前的太阳位置渲染芝加哥的摩天大楼。伊利诺伊州的 GMT 是 -6; 只需将时区设置为 -6。

Since Daylight Saving Time jumps forward 1 hour, Illinois’s DS Time Zone would then be -5.

由于夏时制时间向前跳跃1小时，伊利诺伊州的 DS 时区就会变成 -5。

New City

新城区

  1. Enter the corresponding longitude, latitude, Daylight Saving time zone, Time Zone, and DS Time Zone for your city. 输入您所在城市的相应经度、纬度、夏时制、时区和 DS 时区

  2. Click on the small button to the far right of the 点击最右边的小按钮City 城市 slider 滑块 and select 然后选择New City 新城区 from the menu that appears. The following window will open: 下面的窗口将会打开:
