专业的方法来学习如何绘制。一个训练有素的艺术家必须掌握像一个作家的主人语法的角度。这一系列的角度讲授，学习如何绘制在空间中存在的任何的权威来源。它们不是华而不实的制作，他们是马歇尔和黑板。这些影片是我们知道的最好方式，来学习如何绘制专业。掌握这些录像带的内容，你掌握了一个艺术家需要知道的角度问题。
讲座1：
透视简介
这个讲座是该课程的概述。它解释观点是什么，为什么它的困难，以及如何简化，使其有用。马歇尔定义的条款，您将需要的课程，并给出了五种方式艺术家在一个平面上创造深度的幻觉。
讲座2：
直角部分1
本讲座说明了为什么的平行线似乎距离，以满足。你会明白为什么地平线和你的眼睛水平始终是相同的东西。你也可以看到，如果你能画出一个立方体，你可以得出几乎任何东西。
讲座3：
成直角的第2部分
了解为什么照相机的镜头有不同的焦距，只要你犯了一个图片，你是给你的观众把你的消失点广角，正常或远摄的主体。这是歪曲和夸大的对象秘密。
讲座4：
第3部分成直角
了解图纸“结构的方法”，让你“看穿”的对象和借鉴看不见的线。同样的方法可以绘制在开放空间的群体，并保持其明显的大小一致，因为他们变得遥远。同时学习两个应用和如何克服这些危害。
讲座5：
圆形和椭圆形的一部分1
界到处都是，和椭圆形的角度界。不好构造椭圆未受过训练的艺术家最快的赠品之一。这个示范，告诉你如何构建一个精确的椭圆形，以及如何可以提高您的FreeHand圆截面的任何图纸。
第6讲：
圆形和椭圆形第2部分
该演示将向您展示如何克服两个最令人费解的问题，初学者在试图把车轮上车或门上的旋钮：寻找在太空中圈的中心，并把正确的角度。在不到一个小时，这些问题将得到解决你的职业生涯中的其余部分。
第七讲：
圆形和椭圆形第3部分
拨号，齿轮，罐或花瓶的设计是没有得到解决的猜测。他们可以得出准确和自信。本次演讲展示了如何通过学习掌握一个球体环绕线的任何一轮的形式，无论是工业或自然，。
讲座8：
圆与角度组合
门，框皮瓣甚至人类的四肢，创建新的绘图问题，因为他们在一个铰链摆动。他们解决相结合，到目前为止所过程中的所有材料。
讲座9：
斜面与消失的TRACE
任何表面不水平，需要自己的天际线和消失点。怎么找呢？本次演讲会告诉你，“消失跟踪”是所有你需要绘制屋顶，楼梯和任何其他的表面，倾斜向上或向下。
讲座10：
深度测量系统的一部分1
本次演讲的五个方法“衡量回太空”纸张的平坦的表面上覆盖三个。前两个是简单快捷，但有限的。第三个系统，可以让你精确绘制栅栏，地板瓷砖，或任何与定期测量回落。
第11讲：
深度测量系统的组成部分2
这是一种更先进的系统，让您将其放置在墙壁或地板或楼梯任何复杂和不规则的设置和测量，知道在何处放置的每一点的示范。最终的系统是非常容易的，当你知道有关“特殊的消失点。”
讲座12：
计划投影
一个3D程序如何让你从任何角度看到一个假想的对象呢？它使用同样的方法艺术家们使用了几百年。了解如何一个顶部，侧面和前视图可用于绘制一个对象，从任何角度来看。
Perspective series 12 by Marshall Vandruff | .avi | 4.23Gb
The Professional Approach to Learn How to Draw. A trained artist must master perspective like a writer masters grammar. This series of perspective lectures is the definitive source for learning how to draw anything that exists in space. They are not slick productions; they are Marshall and a chalkboard. These videos are the best way we know to learn how to draw professionally. Master the content of these tapes and you master everything an artist needs to know on the subject of perspective.
LECTURE 1:
INTRO TO PERSPECTIVE
This lecture is an overview of the course. It explains what perspective is, why it's difficult, and how to simplify to make it useful. Marshall defines the terms you will need for the course and gives the five ways artists create the illusion of depth on a flat surface.
LECTURE 2:
RIGHT ANGLES PART 1
This lecture demonstrates why parallel lines seem to meet in the distance. You will understand why the horizon and your eye level are always the same thing. You will also see that if you can draw a cube, you can draw practically anything.
LECTURE 3:
RIGHT ANGLES PART 2
Learn why camera lenses have different focal lengths and how whenever you make a picture, you are giving your viewer a wide-angle, normal or telephoto view of the subject by placing your vanishing points. This is the secret of distorting and exaggerating an object.
LECTURE 4:
RIGHT ANGLES PART 3
Learn the "structural approach" to drawing that lets you "see through" objects and draw the unseen lines. This same approach allows you to draw groups of people in open spaces and keep their apparent sizes consistent as they become distant. Also learn the two hazards of applying this and how to overcome them.
LECTURE 5:
CIRCLES & ELLIPSES PART 1
Circles are everywhere, and ellipses are circles in perspective. Poorly constructed ellipses are one of the quickest giveaways of the untrained artist. This demonstration shows you how you can construct a precise ellipse and how you can improve your freehand drawings of anything that has circular sections.
LECTURE 6:
CIRCLES & ELLIPSES PART 2
This demonstration will show you how to overcome the two most baffling problems beginners have in trying to put wheels on cars or knobs on doors: finding the center of the circle in space and placing the angle properly. In less than an hour, these problems will be solved for the rest of your career.
LECTURE 7:
CIRCLES & ELLIPSES PART 3
Dials, gears and designs on cans or vases are not solved by guesswork. They can be drawn accurately and confidently. This lecture shows how to master any round form, whether industrial or natural, by learning to wrap lines around a sphere.
LECTURE 8:
CIRCLES & ANGLES COMBINED
Doors, box flaps and even human limbs create new drawing problems because they swing on a hinge. They are solved by combining all the material covered in the course so far.
LECTURE 9:
INCLINED PLANES & THE VANISHING TRACE
Any surface that is not level needs its own horizon line and vanishing points. How do you find them? This lecture will show you that the "vanishing trace" is all you need to draw rooftops, stairways and any other surfaces that slant up or down.
LECTURE 10:
DEPTH MEASURING SYSTEMS PART 1
This lecture covers three of the five ways to "measure back into space" on the flat surface of your paper. The first two are simple and quick, but limited. The third system allows you to precisely draw picket fences, floor tiles, or anything that recedes with regular measurements.
LECTURE 11:
DEPTH MEASURING SYSTEMS PART 2
This is a demonstration of the more advanced systems that will allow you to place any complex and irregular set of measurements onto a wall or a floor or a stairway and know where to place every point. The final system is surprisingly easy when you know about the "special vanishing point."
LECTURE 12:
PLAN PROJECTION
How does a 3D program let you see an imaginary object from any angle? It uses the same method artists have used for hundreds of years. Learn how a top, side and front view can be used to draw an object from any point of view.
