她的每幅画都呈现一幅马赛克图案，或描绘其周围环境。

词汇表
轮廓线（Contour Line）——勾勒形体外轮廓的线条；它们随物体外部边缘弯曲，从而赋予形状以明确外形。

交叉轮廓线（Cross Contour Line）——横跨形体表面、同时呈水平与垂直走向的线条，用以强化三维立体感。
形体（Form）——三维立体造型。可通过明度（明暗/排线）或轮廓线，使二维形状呈现出立体效果。
错位（Stagger）——按规律逐行偏移排列。
透视（Perspective）——观察物体的角度，以及该角度如何影响我们对物体（或情境）的视觉感知。
起稿方式多种多样；首先须选定所用透视类型。
部分透视法难度较高，部分则相对基础。
下方分别为初学者、中级与高级三类透视方案。
所有方案均需先用铅笔起稿：描出圆形轮廓，再添加交叉线条；通常约20条交叉线为宜——线条过多会使镜面马赛克过小，过少则使其过大。
铅笔线将被硬质蜡笔完全覆盖，我们将采用“蜡笔防染”技法。
蜡笔线条之上将施以水彩，色彩涵盖多种浅色调（tint）、深色调（shade）及中间调（tone），以反映迪斯科球所处环境的真实反光效果。
2022年秋季高级美术课（第2、3、4课）
初学者级别
仅使用水平直线——
搭配垂直轮廓线，
不采用错位排列。
中级级别
水平直线 + 错位式垂直轮廓线
\
单色蜡笔……
或从前视角度绘制轮廓线——
中心水平线保持平直……
高级级别
运用视角变化，
垂直与水平方向均采用错位式轮廓线，
并使用多色蜡笔。

难点提示
我在勾勒垂直方向线条时，对每一奇数行进行了错位处理。

VOCABLULARY
Contour LIne- lines that give form to a shape. They follow the shape by bending with the exterior defined lines.

Cross Contour Line- Lines that cross both horizontally and vertically across a shape to make it a form.
Form- 3D Shape. You can use value (shading) on a shape or contour lines to make it appear a form.
Stagger- To shift over in pattern.
Perspective- The angle at which you see things and how it effects the way you see objects/situations.
THERE ARE MULTIPLE WAYS TO START; first you must pick your perspective.
Some perspectives are more advanced than others.
Below is Beginner, Middle, and Advanced perspectives.
Each one you START WITH PENCIL. Trace your circle. Add your crossing lines. 20 or so lines across seems the average amount. More will make the mirror mosaics too small and less will make them too big.
Pencils lines with be covered with HARD CRAYON. We will use the Crayon Resist technique.
CRAYON lines will be covered with WATERCOLOR in a Variety of tines, shades, and tones.
reflect what would be in the environment of the DISCO BALL.
Advanced Art (2,3,&4) of Fall 202
Beginner Level
USING STRAIGHT HORIZONTAL LINES--
and contoured vertical lines

MID-LEVEL
STRAIGHT HORIZONTAL and CONTOUR STAGGERING VERTICAL

For ADVANCED-
Using a change in perspective.
staggered CONTOUR LINES VERTICALLY and HoRIZONTALLY
with mulit colored crayons
