Pointing at the viewer
- Foreshortening 透视缩短 is perspective applied to a single form pointing toward you.
- Lengths compress dramatically: a pointing arm may appear one-third of its true length.
- Draw the apparent shape, not the length you know.
指向观者
- 透视缩短(foreshortening)是透视作用在一个指向你的形体上。
- 长度被急剧压缩：指向你的手臂可能只显出真实长度的三分之一。
- 画看到的形状，不是你知道的长度。
Foreshortened or not? · 缩短还是未缩短？
Sort each view by whether foreshortening dominates. · 按缩短法是否占主导地位对每个视图进行分类。
In foreshortening, overlap between parts is a key depth signal. · 在缩短法中，部件间的重叠是关键深度信号。
Hand over forearm over upper arm. · 手在前臂前，前臂在上臂前。
Overlap is the signal
- Overlap tells the story: the hand overlaps the forearm, the forearm overlaps the upper arm.
- Think in cross-sections 横截面 — rings around the form, like a wireframe, feeling how it turns toward you.
- Measure the compressed lengths by sighting: memory lies, observation tells the truth.
遮挡是信号
- 遮挡讲出故事：手盖住前臂，前臂盖住上臂。
- 用横截面(cross-sections)思考——像线框模型一样套在形体上的环，感受它如何转向你。
- 用目测去量被压缩的长度：记忆说谎，观察才说真话。
A foreshortened pointing arm may appear about ____ of its true length. · 缩短的手臂可能看起来约为其真实长度的____。
Compression is dramatic and varies with the angle. · 压缩效果显著且随角度变化。
Imagining rings around a form, like a wireframe, means thinking in ____. · 想象围绕形体的环状结构，如同线框，意味着在____中思考。
Cross-sections reveal how the form turns toward you. · 横截面揭示形体如何转向你。
The classic practice
- Mantegna's Dead Christ is the textbook example: a figure drawn feet-first.
- Practise with your own foot propped up, or a friend lying feet toward you.
- One convincing foreshortened form is high-value portfolio evidence.
经典练习
- 曼特尼亚的《哀悼基督》是教科书式的例子：从脚的方向画的人。
- 用自己搁起的脚练习，或请朋友脚朝你躺着。
- 一个画得可信的透视缩短形体是作品集里的高价值证据。
Select all · 所有 good foreshortening habits. · 选择所有良好的缩短法习惯。
Drawing known lengths is exactly the error. · 画出已知长度正是错误所在。
Match the artwork or setup to the idea. · 将艺术作品或设置与理念匹配。
Three ways into foreshortening. · 进入缩短法的三种方式。
Foreshortening breaks the moment you draw "what an arm is" instead of "what I see". If the drawn arm looks too short to be right — measure again; correct foreshortening always feels too extreme at first.
一旦画"手臂应有的样子"而不是"我看到的"，透视缩短就失败了。如果画出的手臂短得让你怀疑——再量一次；正确的透视缩短一开始总感觉太夸张。
Point your own arm at a mirror: the upper arm nearly vanishes, the forearm is a stub, the hand looms huge with fingers overlapping everything. Draw those three overlapping shapes — the arm reads instantly.
对着镜子伸出手臂：上臂几乎消失，前臂只剩一小截，手显得巨大、手指遮住一切。把这三个互相遮挡的形状画下来——手臂立刻成立。
Foreshortening compresses lengths along the view axis: trust sighting over memory, lean on overlap, think in cross-sections, and accept that correct always feels extreme.
透视缩短沿视线方向压缩长度：相信目测而非记忆，依靠遮挡，用横截面思考，并接受"画对了反而感觉夸张"。
