文本 物体与其字面意思一样：包含文本。作为现代字体（OpenType, TrueType等），其物体类型为曲线和曲面，是矢量物体，由曲线（通常为贝塞尔曲线）构成。
Blender uses a "Font System" to manage mapping "letter codes --> objects representing them in 3D views". This implies that not only does the font system have its own built-in font, but it can use external fonts too, including PostScript Type 1, OpenType and TrueType fonts. And last but not least, it can use any objects existing in the current blend-file as letters...
Texts in Blender allow you to create/render 2D or 3D text, shaded as you want, with various advanced layout options (like justifying and frames), as we will see below. By default, letters are just flat filled surfaces, exactly like any closed 2D curve. But you can of course extrude them... And texts can follow other curves.
Of course, once you are happy with the shape of your text, you can convert it (with Alt-C, in Object Mode), either to a curve, or directly to a mesh, allowing you to use all the powerful features of these types of objects on it...
Fig. 文本示例。 shows some examples of various fonts in action, including the "blue" font that has been applied to a curve path.
A maximum of 50000 characters is allowed per text object; however, be forewarned that the more characters a single text object has, the slower the object will respond interactively.
As you can see when you switch between Object Mode and Edit Mode, the Font panel remains the same. This means that its settings can be applied equally in both modes ... and this implies that you cannot apply them to just a part of the mesh. So font, size, and so on, are common to all letters in a Text object. There is just one exception: the Bold or Italic buttons control properties specific to each letter (this is a way to use up to four different fonts in a text).
