Scott Robertson的兩本教學書

How to Draw: Drawing and Sketching Objects and Environments from Your Imagination

How to Render: The Fundamentals of Light, Shadow and Reflectivity

中文版說要出說了快三年,結果連個影子都沒有看到,最後還是只能入手英文版QQ

第一本書已經看過好幾遍了,正在翻第二本,有個很有價值的東西想和大家分享:那就是對於第一本書的基本能力的總結,總共分成四個部分,大家可以自我檢驗看看是不是都已經掌握這些基本能力了。

1.Perspective Grid Skills

Before proceeding with the exercises in this chopter, it is absolutely necessary to be proficient in creating perspective grids, including drawing toward Vanishing Points that are off the page, as well as being familiar with Auxiliary Vanishing Points. Mastery of these skills ensures that you are always in control of the scene being drawn, knowing where all points are relative to one another in perspective.

2.Form-Building Skills

Creating X-Y-Z volume constructions helps to understand and communicate a design, and plan for shadow construction . It enables the addition of details to the rendered shape, such as cut lines or other elements. One must have the skills to create these types of constructions for advanced form renderings, since it will be necessary to move back and forth fluidly between plotting construction lines and developing a design with value .

3.Construction Skills

For many of the upcoming shadow-casting constructions, the skills to transfer height points, in perspective, is needed. When objects are under a light source, transferring their height to a vertical line creates what is called a Shadow Origin (A, B). There are multiple ways of doing this, all of which rely on strong perspective construction skills.

4.Section Drawing Skills

Most constructions require drawing a line on the ground, through the object, in the direction of the cast shadow (A), and then constructing a vertical plane from this line, that cuts through the object (B) . It is important to know how to create section lines, which can range from rectangular sections over complex planar forms, to curved sections over X-Y-Z forms.

  1. 其實中文版是有,不過是愛好者自翻的…
    這兩本是art center在過去幾十年裡對概念設計(電影、遊戲)的理解、開創與經驗累積而成,對想進入業界的朋友所提供的一些基礎訓練與知識,對最後如何快速提供想法、與可供3d建模有很大的幫助,相信他第三本(如果會出的話)會有更深一層的分享
