TTL(Through The Lens)

The thought of Through-the-lens Control (TTLC) improves the efficiency and interactivity of 3D scene design largely, by allowing users to operate the projections of objects directly in order to set the components in 3D scene.

上世纪九十年代提出的通过镜头控制(Through-the-lens Control,TILC)思想,允许用户可以直接对物体在平面图像上的投影进行操作来对3D场景中的各组件进行设置,大大促进了三维场景制作的效率和交互性。
