Rigging a Life-Size Dinosaur: What Buyers Should Ask Before Production | 大型恐龙绑定制作：开工前该问清楚的几件事

The rig follows the use case

A rig built for a film shot and a rig built for a real-time exhibit are not the same object. Film work tolerates heavy controls and dense deformation because frames are rendered offline. Real-time exhibits need light skeletons, predictable frame cost and a limited control set that an operator can drive without a technical artist on site.

Start from the joint hierarchy, not the controls

The joint hierarchy is the contract between model and animation. Ask for a written list of joints, their parent relationships and which of them are driven by the animation system versus by hand. A clean hierarchy makes later changes cheap; a messy one makes every retarget expensive.

Deformation is where realism is won or lost

Large creatures fail at the neck, the hips and the base of the tail, where skin stretches over big ranges of motion. Check those areas at extreme poses rather than at rest. Weight the model, test it, and inspect the silhouette from the angles the audience will actually see.

Deliver both the rig and the documentation

A rig without documentation is a black box. A useful delivery includes a control sheet, naming conventions, unit and axis settings, and a short note on known limits. If the client will retarget animation, confirm that the skeleton follows a known convention before production starts.

Questions worth asking early

Which engine or software will consume the rig? How many animation clips are expected? Will a performer drive it in real time? Does it need to match an existing skeleton? Answers to these four questions usually decide the rigging budget more than the polygon count does.

DinoCG prepares rigs for museum, theme-park and film projects, and matches the rig to the delivery platform rather than defaulting to a single template.

绑定跟着用途走

为影视镜头做的绑定和实时展厅用的绑定不是一回事。影视可以承受较重的控制器和密集的形变，因为画面是离线渲染的。实时展项需要轻量骨架、可预期的算力开销，以及现场人员不需要技术美术也能操作的精简控制集。

先定关节层级

关节层级是模型与动画之间的契约。请对方给出关节清单、父子关系和哪些关节由动画系统驱动、哪些靠手动。层级干净，后续修改成本低；层级混乱，每次重定向都要重新付学费。

形变决定真实感

大型生物最容易在颈部、胯部和尾根出问题，因为这些位置在动作中拉伸幅度最大。要在极限姿态而不是静止姿态下检查，蒙皮后实测，并从观众真正会看到的角度看剪影。

绑定和文档一起交付

没有文档的绑定等于黑箱。可用交付应包含控制器说明、命名规范、单位与坐标轴设置，以及已知限制的简短说明。如果后续要重定向动画，请在开工前确认骨架是否遵循通用命名。

值得提前问的问题

用哪个引擎或软件？预计多少段动画？是否需要真人实时操作？是否要匹配已有骨架？这四个答案对绑定预算的影响，通常比面数更大。

DinoCG 为博物馆、主题公园和影视项目制作绑定，并按交付平台匹配方案，而不是套用单一模板。
