维克多·瓦萨雷利(上图)与布里奇特·赖利(下图)
是欧普艺术(视错觉艺术)的“国王”与“王后”。

他们运用线条在空白区域中塑造形体与动感。
弯曲的线条(即轮廓线)可在平面表面营造出三维立体的错觉。

杰茜与埃斯特雷拉

我们将在线稿上同时使用平直线条与弯曲线条。
如同维克多·瓦萨雷利所绘的凸起球体,
我们的背景采用平直线条,而手部则用弯曲的“轮廓线”。
最终效果将呈现为:手仿佛正从带线条的纸面之下向外凸起。

- 用铅笔轻轻描出手的轮廓(后续将擦除)。
建议以浅色横格纸作为辅助线参考。
- 在整张纸上画横贯左右的直线。
当线条碰到手指时,向上跃过手指,再于手指另一侧接续同一条线;
当线条碰到手掌时,同样向上跃过手掌,再于手掌另一侧接续同一条线。
*提示:跃线时(无论向上或向下),需保持统一——
我选择在所有部位均仅跃过一条线,并尽量使跃升高度在形体中心处达到最高。
--------------------请做出选择----------------
马克笔 还是 彩铅?
马克笔
- 用马克笔为所有线条着色,可采用两种或更多颜色组成的图案。
- 用黑色蜡笔或彩铅沿手部外缘勾勒轮廓线,再轻轻在轮廓线外侧涂色,以暗示投影。

2021年
- 以中等力度为背景着色,采用两种或更多颜色组成的图案。
- 以较重力度沿手部边缘着色,以暗示投影。
- 以中等力度为手部着色,
但手指尖端、掌心及手腕/前臂的最高点除外——
这些部位应留白或轻涂,以表现来自上方光源的高光。


埃斯特雷拉(八年级/2021年)正使用彩铅在手部塑造立体感。

Tags: op art optical hand illusion 3d contour lines


Victor Vasarley (above) and Bridget Riley (below)
are the King and Queen of Op Art (Optical Illusion Art).


They used lines to create form and movement on empty spaces.
The use of bending lines (contour line) creates the illusion or three dimension on a flat surface.


Olivia , Jorja,
Jaycee, and Estrella


We are going to use flat and bending lines on our paper.
Like Victor Vasarley's bulging sphere,
our back ground will be flat lines and our hand will have bent "contour" lines.
It will appear as though it is bulging from under the lined paper.




- Trace your hand with a pencil lightly (you will erase it later).
It is best to used lightly lined paper as a guide.
- Make lines straight across paper.
When the line hits the finger, jump up and then join the same line at the other end of the finger.
When the line hits the hand, jump up and then join the same line at the other end of the hand.
*Hint- when jump line upward or downward with the lines, be consistent
I jumped one line only on all parts, stying to go highest in the center of the shape.
--------------------MAKE A DECISION----------------
Marker or Colored Pencil?
MARKER
-
Color all lines with the marker, you can use a pattern of 2 or more.
-
Using a black crayon or colored pencil, add an outline around hand then lightly color around the outline to suggest a shadow.

-
Color background using a medium pressure with a 2 or more color pattern.
-
Color with harder pressure around hand to suggest a shadow.
-
Color hand with medium pressure,
except the highest points of the fingers, palm and wrist/arm
to suggest highlights from light source above.





Estrella (8th grade/2021) is using colored pencils to create form on her hand.
