发信人: giky (魏小宝~~我要发明隐形药), 信区: ASCIIart 标题: Asciiart课堂教程2－－立体效果发信站: 饮水思源 (2003年09月10日23:55:35 星期三), 站内信件上一节给大家介绍了一些光影色彩的技巧，这节我们进一步利用光影来具体到一个常用的实例－－立体效果。注意：本节课的范例请全部无缝查看。 asciiart 是二维图像，要通过平面来表现三维的东西，就必须利用颜色的明暗来造成一些视觉的错觉。我们来打个比方： ◢◣ ◢◣ ◢██◣ ◢██◣ 平面图： ◢████◣ 立体图： ◢████◣ ◥████◤ ◥████◤ ◥██◤ ◥██◤ ◥◤ ◥◤ 如何实现立体效果呢？就是做出光照在立体物上造成的明暗变化，和影子就拿刚才的例子来说吧：亮色光 ↘ │ ↘ ↓◢◣ 灰色 ↘ ◢██◣↙ ◢████◣ ◥████◤ ◥██◤←深色 ↗ ◥◤ 灰色另一种就是把物品的影子表现出来打个比方符号艺术这样就能造成悬空的感觉，这我们在上一课中也提到过。比较常用的一种立体效果就是浮雕效果，用浮雕作边框 ·╭┬────────────────────────────────╮· ╭╯█┐ 朋友你看起来二十出头了吧你一定听说过男孩心声板可是你不想又 ╰╮ │ └█┐ 或者你不敢其实写一点东西很简单他们都很善良考虑一下尽快来吧 │ │ ┌┼█────────────────────────────── │ ╰╮█┘ 谈天聊地--->男孩心声 BM: BoyzIIMan tramp ╭╯ ·╰┴────────────────────────────────╯· 用浮雕作装饰 ╱╲ ╱╲ ╭╮ ∧ ╱╱╲╲ ╱╱╲╲ ╰╯╭╮ ∨ ╱╱╱╲╲╲ ╱╱╱╲╲╲ ╰╯ ╱╱╱╱╲╲╲╲ ╱╱╱╱╲╲╲╲ ┌─┐ ╱╱╱╱╱╲╲╲╲╲ ╱╱╱╱╱╲╲╲╲╲ └─┘ ╲╲╲╲╲╱╱╱╱╱ ╲╲╲╲╲╱╱╱╱╱ ╲╲╲╲╱╱╱╱ ╲╲╲╲╱╱╱╱ ╲╲╲╱╱╱ ╲╲╲╱╱╱ ╲╲╱╱ ╲╲╱╱ ╲╱ ╲╱ 另外一种表示立体的方法就是用画面表现出立体图形的不同侧面。最简单的例子： _____ ╱ ╱▏ 很多字体中也用了这种方式： ▏ ╱ ◤ ╱◤ ╱◤╱╱ ◤ ╱ ◤╱ ╱◤╱◤╱ ███◢███╱◢█◣╱██◣╱◢██╱█ █ █▅▅╱█▅▅╱█▄█ █▃█ █ ███ ▅▅█◢█▄▄◢█ █◢█ █◢◥██◢█ █╱ 一种更高的技巧就是将剖面图表现出来：例： ╱◢__ ________ │ 俱乐部 ╱◢◤◢◤____ ◢ │ ╱◢◤◢◤◢__◤◢█__ │ 还有一种立体效果就是利用近大远小的 ╱◢◤◢◤ ◢█◤◢ │ ╱▏█ ____ █◤◢◤ │来创造立体的效果： ╱▏█ ◤ ◤◢◤ │ ╱▏__ ____ __◤ │ 例： ╱▏◤__◤▕ ◤ │ ╭) ╭) ╱╱╱◤____ ____◢ │ ╰ ╯ ╰ ╯ ╱╱◤◢__◤◢__ █ │ 刂 / \ 刂 ╱◤ ◢ █ │ ︿ / \ ︿ ╱▏____ ____◤ █ │ (╭)) / \ (╭)) ╱◤◢╱▏█◤◢__◤ │ ╰ ╯/ \ ╰ ╯ ╱▏█◤▏█▏█ │ 刂 / \ 刂 ╱▏◤▏ ◤▏◤ __ │ ╱╱╱◤ __ ◢◤◢ │ 还有就是用亮色来凸出棱角，表现出立体的 ╱╱╱◤◢◤◢◤◢█ │感觉 ╱◤ ◢◤█ │ 例： ╱▏ █__█ │ ﹒ ﹒ ﹒ ______________________ ╱◤ ◢▏█◢◤ │ _______________________︳ ╱▏____ █▏█◤ │ _______________________︳ ╱▏◤▕ █▏█ │ _______________________︳． ◤▏ ◤▏◤ │ ______________________︳ ﹒ ﹒ 能用来表现立体效果的技巧很多，我只是给大家总结些常用的，也算给大家一个思路。大家充分返回想像，一定能作出更完美的立体效果来。

Sender: giky Wei Xiaobao I want to invent invisible medicine, message area: ASCIIart Title: Asciiart Classroom Tutorial 2 Three-dimensional Effect Sending site: Drinking water and remembering its source Wednesday, September 10, 2003 at 23:55:35, site mail The previous section introduced you to some techniques of light and shadow color. In this section we further use light and shadow to specify A commonly used example: three-dimensional effect Note: Please view all the examples in this lesson seamlessly. asciiart is a two-dimensional image. To express three-dimensional things through a plane, you must use the light and shade of colors. to create some visual illusions Let's make an analogy Plan view 3D view How to achieve a three-dimensional effect is to create the light and dark changes and shadows caused by light shining on a three-dimensional object. Let’s take the example just now. Bright color Light grey Dark grey The other is to show the shadow of the object For example symbolic art This will create a suspended feeling, which we also mentioned in the previous lesson. One of the more commonly used three-dimensional effects is the relief effect. Use relief as a border My friend, you look like you are in your early twenties. You must have heard of the Boy’s Voice Board, but you don’t want to do it again. Or you don’t dare. In fact, it’s very simple to write something. They are very kind. Consider it as soon as possible. Chat >Boy’s Voice BM: BoyzIIMan tramp Decorate with reliefs Another way to represent a three-dimensional figure is to use pictures to show different sides of the three-dimensional figure. The simplest example This method is also used in many fonts A more advanced technique is to represent the profile example club There is also a three-dimensional effect that uses the near large and far small to create a three-dimensional effect example 刂刂刂刂 There is also the use of bright colors to highlight the edges and corners and show a three-dimensional look. Feel example ﹒ ﹒ ﹒ ﹒ ﹒ There are many techniques that can be used to express three-dimensional effects. I just summarize some commonly used ones to give you an idea. If you fully return to your imagination, you will definitely be able to create a more perfect three-dimensional effect.
