Genemation GenHead v3.1
GenHead是一款独立的工具软件,其目的是使专业或是业余的数码设计艺术家迅速且轻松地从二维数码人物相片创建三维头部图像。
概述：
在理想的情况下，GenHead需要一张正面和侧面的人物相片，但是如果只有一张正面相片，GenHead则会利用所有可用的姿态来综合创建出三维头部图像。对於所需的相片并没特殊设备的要求，标的数码相机就可以，在摄相时细心一点将有助於得到最佳化的三维头部图像。
在将你的相片处理成三维头部图像的过程中，GenHead会一步步指导你，所以也无需过多的经验：
*首先导入你的照片（有预览窗口以便检查可能存在的问题）
*接著GenHead将提示你纠正相片上任何有问题的地方,以争取能得到最佳化的结果。你可以确定方向、调整亮度或是颜色平衡。
*之后GenHead需要你在你相片脸部周围作一些标记，这时会有一个帮助窗口给你提供帮助，这将使你的操作变得很简单。整个过程只需几分就足够了，最后GenHead会提示你生成三维头部图像。
*这时会打开一个新的窗口自动载入你最初的相片和已生成的三维头部图像。
*接下来通过使用GenHead中的工具对三维头部图像作一些细部的修改。
*立体化的预览窗口会实时更新你的修改。
*GenHead会自动生成一个bump map。
*GenHead能生成左右对称或不对称的头部图像, 并且可以独立地设置形状以及纹理。
*最终当你对你的三维头部图像感觉满意之后，可通过各种不同的格式输出：
- maya binary (.mb)
- fbx,
- dotXSI,
- vrml
- obj.

GenHead v3.1:
GenHead is standalone software tool that is designed to enable both professional and amateur digital content artists to quickly and easily create 3D heads from 2D digital photographs. The resultant component parts (mesh and texture), including a 'bone rig' for animation, can be exported into industry-standard art/animation tool suites in a variety of file formats, mesh resolutions and texture sizes.
Overview of the GenHead:
GenHead ideally requires a front and profile photograph of the target. If a front profile is all that's available GenHead will synthesis a profile when creating the 3D head. No special equipment is required, a standard digital camera (>4MP) will suffice. A little care in taking the pictures will help ensure you get the best possible 3D head.
GenHead guides you through the process of turning your photo into a 3D head, so no experience is necessary:
First of all you import the photos (there is a preview window so you can check you've got the right ones.)
Next GenHead prompts you to correct any problems with the images in order to get the best possible result. You can correct their orientation and you may adjust the brightness and colour balance.
After that, GenHead requires that you to place a series of markers around the face. An active Help window shows you where to place each marker, making it a simple process.
This whole process takes only a few minutes, then GenHead prompts you to generate a 3D head.
A new window is automatically loaded in which you will see your original 2D front and profile images in their own pane, and a seperate pane with the resultant 3D head. These panes can be scaled as required as can the images
At this point GenHead gives a you a number of tools with which to modify the geometry and texture to high LOD. The shape and the texture mapping can be altered together or independently, delivering quick results and the flexibilty to get the head exactly right.
The 3D preview window immediately updates as you make changes so you can see the effects of your changes. The preview mesh can be shown in various modes; including a new high-quality mode where the bump and specular maps are also rendered.
GenHead automatically generates a bump map.
GenHead can generate left or right symmetric, or assymetric heads; and the symmetry of the shape and texture can be set independently.
When you are happy with the 3D head you've created it can export it in a variety of formats:
- maya binary (.mb)
- fbx,
- dotXSI,
- vrml
- obj.
The supplied mesh is a high quality quad mesh (which enables easy subdivision, in ZBrush for example). There are 4 export mesh resolutions: 1, 2, 5 and 9k. All of these mesh resolutions come complete with a bone rig for animation
The meshes can be imported into Maya (.mb file compatible with 6.0, 6.5, 7.0), Max, SoftImage and other packages where finishing touches, e.g. adding hair, can be made. Animation can then generated, and to speed this up the bone rig is supplied with an animation which cycles through sample expressions and visemes.
