如何使用 Inkscape 制作万圣节灯笼

由 廉价感情. 提交于 2020-04-27 17:32:36
使用开源软件为你最喜欢的万圣节鬼屋制作一个有趣和怪异的装饰品。 使用开源软件装饰一个独一无二的万圣节灯笼！ 通常，灯笼的一部分结构体是不透明的，以阻挡内部的光线。灯笼之所以成为灯笼，是因为其去掉了一些东西 ：从结构体上切开的窗口，这样光线就可以射出。虽然对于照明来说不实用，但是一个有着怪异形状窗口和隐藏暗色轮廓的灯笼却可以令人兴奋，并创造出很多乐趣。 这篇演示如何使用 Inkscape 创建你自己的灯笼。如果还没有 Inkscape ，在 Linux 上，你可以从软件库中安装它，在 MacOS 和 Windows 上，你可以从 Inkscape 网站 上下载它. 使用材料 模板（ A4 或 信纸 大小） 卡片纸（黑色是传统色） 描图纸（可选） 裁纸刀、尺子、切割垫板（可使用工艺切割机/激光切割机代替） 工艺胶 LED 茶灯 蜡烛 安全注意事项：这个项目只使用电池操作的蜡烛。 理解模板 首先，从上面的链接下载你所在区域（A4 或信纸）的合适的模板，然后在 Inkscape 中打开它。 灰白色的棋盘格背景是透明的（从技术角度来说，它是 alpha 通道。） 黑色基板构成了灯笼。现在，没有窗口可以让光线穿过；灯笼有一个非镂空的黑色基板。你将在 Inkscape 中使用 并集 和 差集 选项来数字化的设计窗口。 蓝色虚线表示折线。橙色实线表示参考线。采光窗口不应该放在橙色盒子的外面。

问题 I want to send a "fact" to a JESS file within java and get the results back. I basicly batch the JESS file and then send my data (structure in here) into the engine by .add(). I tried to get the JESS results, which should be a string, into a "Value". Rete engine = new Rete(); engine.batch("file.clp"); Value = AAAnull; try{ engine.add(structure) AAA = engine.eval("(run)"); } catch ... System.out.println(AAA); The result is always a number, although the result should be a string. I have worked

Jess printout contents print in Java

问题 I am trying to get the printout contents from a Jess RHS of a rule. A similar question is described here: Output of JESS in Java but there is not a concrete solution how to use a router for the printout command. Instead of printing the rule's printout contents in Java console I want to print them in a dedicated JTextArea. I declared a string e.g. String result; to hold the contents and then print out the string contents into JTextArea through outputTxt.setText(result); 回答1: The Jess manual

Increment or change variable each time Jess rule fires

由 北城以北 提交于 2019-12-13 03:32:06
问题 Is there a way to increment or change value of some variable each time rule fires? I need that for every time rule fires introduce new value of the slot, since I will use this value for connectivity in the following example: I have an electric circuit and rule that transforms delta to star. For every transform product is additional node. For simple network I have named it T, but for more complicated network I end up with network that is full of T nodes, since every time rule is triggered for

What are the pros and cons to adopting the Java rules engines JESS and Drools ? Are there any other players? I understand that Drools is Open Source and JESS is not, but how do they compare in other areas like ease of use, performance, level of integration with your code? Pascal Thivent What are the pros and cons to adopting the Java rules engines JESS and Drools? Use a rule engine if you need to separate the business rules from the application logic. The Does Your Project Need a Rule Engine article has a good example: For example, a typical storefront system might involve code to calculate a

Number equality test fails in CLIPS pattern matching?

问题 I have this following rule in my CLIPS file: (defrule check-final (declare (salience 12)) ?scnt <- (set-count (value ?v) (class ?c)) (test (= ?v ?*total*)) => (printout T ?*total* " == " ?v crlf) ) And I get the following strange output: CLIPS>(run) 14 == 9 5 == 2 How is this possible ???? 回答1: Pattern matching for this rule occurs whenever the fact set-count is asserted or modified. The rule is fired some time afterwards, during the call to run . These two processes can be widely separated

Pattern matching for this rule occurs whenever the fact set-count is asserted or modified. The rule is fired some time afterwards, during the call to run . These two processes can be widely separated in time. The value of ?*v* can of course change during that long period of time. The key is to realize that
