A key frame animation making method and a device for simulating construction progress

Abstract

The invention relates to a key frame animation making method for simulating construction progress, which comprises the following steps: construction animation effects are classified according to types; The animation time corresponding to the key frame is selected on the animation time axis, and a new key frame is created. The key frame records the following related information: the animation timeT corresponding to the key frame, the construction date D, and the current camera state; Repeating the steps to create a series of key frames on the time axis to form a construction animation key frame sequence; According to the related information recorded in the adjacent key frames, by linear interpolation, the camera animation state and construction date animation state corresponding to each intermediate frame are calculated, the scene camera is updated to the calculated camera state, the building model is updated to the construction state corresponding to the construction date, and the animation time is continuously changed to form a coherent camera animation and construction date animation effect. The method comprises the following steps: the user interacts with each other in a few simple steps, and the construction animation of the image can be quickly produced.

Description

technical field [0001] The invention relates to the technical field of key frame animation generation, in particular to a key frame animation production method and device for simulating construction progress. Background technique [0002] With the development of computer software and hardware technology, in order to better display the construction process, more and more engineering projects have used 3D animation technology to simulate and display the key construction process in the links of bidding, evaluation, and reporting. Through the animation display, the relevant design concepts can be expressed more vividly and intuitively, and the communication effect can be significantly improved. How to help users make construction animations quickly and efficiently is a problem that related design software needs to solve. [0003] The existing animation production process is generally divided into several steps such as building a model, setting lighting materials, setting frames...

AI Technical Summary

Problems solved by technology

[0004] However, there are many shortcomings in the existing animation production methods for simulating construction progress.

On the one hand, the existing relevant design software (Take AutoDesk 3ds Max as an example), most of them require cumbersome and complicated production processes when making key frame animations, and users need to set cumbersome animation parameters for the model in order to achieve corresponding animation effects ; On the other hand, the producers need to master a certain knowledge of animation production, and the threshold for use is relatively high. Under the condition that the construction animation producers do not have a rich background knowledge of animation production, using the existing technology to produce the interaction between the lens animation and the construction progress animation Coordinated animation works require a huge learning cost and production effort, and it is impossible to quickly and efficiently produce construction animation effects
