obtaining, by one or more processing devices, a target rich text, comprising

obtaining a rich text template related to the 3D model, and

filling in the rich text template based on user information, to obtain the target rich text;

invoking a rendering tool corresponding to a file format of the target rich text;

pre-rendering the target rich text using the rendering tool, to obtain a rendering result;

invoking a graphical programming interface,

wherein the rendering tool is provided by an application programming interface distinct from the graphical programming interface;

generating the 3D model using a 3D engine, the 3D engine being distinct from the application programming interface used to pre-render the target rich text; and

texture mapping the rendering result to an area of the 3D model using the graphical programming interface.

9. The non-transitory, computer-readable medium of claim 8 , wherein texture mapping the rendering result to the area of the 3D model comprises:

11. The non-transitory, computer-readable medium of claim 10 , wherein the graphical programming interface comprises OpenGL.

12. The non-transitory, computer-readable medium of claim 8 , wherein the 3D model comprises a virtual model in an augmented reality application.

13. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations for displaying rich text on a 3D model, the operations comprising:

obtaining, by one or more processing devices, a target rich text, comprising

obtaining a rich text template related to the 3D model, and

filling in the rich text template based on user information, to obtain the target rich text;

invoking a rendering tool corresponding to a file format of the target rich text;
