And the electronic publishing formats such as mobi and azw3 are established on the format of the ePub, and a free or pay-downloading channel of the user is provided to meet the requirement of the user on books.
Another example is: the calibre reader is software for reading and converting a main PC, and the software supports almost 20 electronic publication formats such as mobi, azw, PDF, txt and the like of almost all ePub format expansion, has the advantages of supporting specifications of ePub2.0 and ePub3.0, is more comprehensive in multimedia file format playing, and can perfectly support video and audio playing of various formats. However, these two software have the following disadvantages: the method has the following defects: kindle is the most popular electronic reader currently but is not friendly in multi-format support, and does not support video and audio playback on the mobile terminal, and applications on PCs do not support full format support for multimedia formats such as video and audio, and although there is a continual increase in performance and presentation effects and personalized formats for ePub, such as support for multiple font effects, applications for the latest frontend techniques have been kept in trial, such as current 3D techniques are essentially blank.
And the second disadvantage is that: calibre has great advantages in converting formats, and also handles in the specification and extension support of ePub, but has the problem of not supporting the 3D resource formats in place in the application of 3D technology.
And the third disadvantage is: kindle, calibre has higher support limitation on the books of education, only can restore the books of education, and cannot better support the teaching activities of experiments and observations in the higher teaching process, such as weaker demonstration of entities in the teaching in medical teaching.
Fourth disadvantage: the existing mainstream electronic reading technology on the market has the defect that the support for texts and pictures is not comprehensive enough. Readers on the market generally stay in the 2D effect display stage, and cannot well apply 3D technology to provide users with a brand new experience.

Wherein, the resource index module further specifically comprises: when books are produced by using the ePub format, adding corresponding 3D model labels and designating resource indexes of 3D models in places needing 3D effect display, namely adding corresponding 3D resources as resource indexes under the resource targets of the ePub, or configuring the corresponding 3D resources on a cloud end, and downloading the corresponding 3D resources through a 3D resource downloading service.
For example: when a user takes a book of a science popularization electronic book of dinosaur, the user opens the science popularization electronic book through a reader supporting 3D effects, the user can know the brief introduction of some characters of the dinosaur in the electronic book and know the appearance of the dinosaur in the 2D world through pictures, when the user clicks book contents such as pictures or characters, the 3D dinosaur model can be directly opened on the characters or the pictures, as shown in fig. 3, the model also has actions and corresponding sounds, the model can be displayed at the top of the book, the user can observe the whole and partial appearance of the dinosaur in a mode of 360 degrees through finger dragging, and the reader can more intuitively see the dinosaur and deepen the cognition of the dinosaur.
The specific operation flow is as follows:
(1) the book editor adds the field by adding the label or adding the field in the original label,
the newly added tag may be as follows:
<model type="model" src="xxxxx"></model>
the original tag newly added field may be as follows:
< p evendata= "showModel: xxxx" > click me view dinosaur p >
Both of the above approaches can be used as a way of 3D model support.
The model resources can be uploaded to a server or directly stored under a corresponding resource directory in the ePub book, and corresponding paths can be configured in the mode.
(2) When the reader opens the corresponding book, the reader can analyze the model tags in the tags and can directly analyze the model tags into indexes of the 3d model.
(3) When a user clicks the content configured with the corresponding model, the reader can judge the clicked label and judge whether the label supports 3D, if the user-defined attribute is not blank, the 3D model is displayed, at the moment, the 3D model is displayed in a background blurring mode, the user can see the real dinosaur model more clearly, and therefore the reader can be deepened to recognize the dinosaur.
The foregoing description is only of the preferred embodiments of the invention, and all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
