The three-dimensional animation production process can be divided into a front production part, a middle production part and a post production part, wherein the front production part comprises: the method comprises the following steps of 1, including the steps of a desk book, a story board, an art draft and the like; the middle-stage production can be divided into links such as models, materials, binding settings, animations, special effect resolving, light rendering, synthesis and the like; the post-production comprises the links of dubbing, mixing colors and the like.
In the middle-stage production process of the three-dimensional animation film, model insertion is always a ubiquitous and troublesome problem in production links such as models, binding setting, animations, special effect calculation, light rendering and the like. The three-dimensional animation production process is a production line type work process, the front link is finished to pass, the next link is carried out, for example, a model is finished to pass, the binding setting link can be entered, the binding setting link passes, the animation link can be entered, the animation link is finished, the special effect resolving link can be carried out, then the lighting rendering link is entered, the error of the front link is amplified continuously in the back link, as can be seen from figure 1, if a character has a model alternation problem in the model link, a large amount of repair workload can be caused, and the back link is reached, the model alternation problem is found in the front link, the repair workload is larger, if the lighting link finds the model alternation problem, the model link needs to be repaired, the binding setting, animation and rendering links need to be reproduced after the model is repaired, and project progress is delayed, a large amount of manpower and material resources are consumed, and the project cost is greatly improved.
At present, in animation production of three-dimensional software (such as maya software), model interleaving occurs in most middle-term production links such as a model link, a binding setting link, an animation link, a lighting link and the like, particularly in the animation link, because each frame has changed dynamic state, the problem of model interleaving is more likely to occur. At present, the problem of model interleaving is checked mainly by experience and a manual multi-angle observation method. Therefore, the working efficiency is relatively low, particularly in animation or special effect calculation links, each frame is needed, multi-angle observation is needed, the consumed time and energy are more, if the examination is not carried out, a large amount of rendering cost is wasted after the rendering is finished, the rendering cost usually occupies a large proportion in the project cost, the project cost is greatly improved, and the manufacturing efficiency is reduced; and at present, the manual inspection model is inserted because no visual detection reference basis exists, the detection is frequently missed after the detection, and the problem of the model insertion cannot be completely avoided.
