Embodiment 1

[0024] Such as figure 1 Shown is a flowchart of a three-dimensional model rendering method provided by an embodiment of the present invention, and the method includes the following steps:

[0025] In step S101, the 3D model to be analyzed is analyzed into multiple components by using a 3D model analysis tool.

[0026] In the embodiment of the present invention, a component is a basic unit of a three-dimensional model, and different three-dimensional models can be rendered in subsequent steps by moving the component. After the terminal obtains the 3D model to be analyzed, it uses the 3D model analysis tool to analyze the 3D model to be analyzed into multiple components. Among them, the 3D model analysis tool can be completed by the program written by the engineer himself, or by means of the 3D model file analysis library (eg: Open Asset Import Library) help.

[0027] In step S102, the data of the plurality of components is sent to the graphics processor (Graphic Processing Un...

Embodiment 2

[0055] Such as figure 2 Shown is a structural diagram of the three-dimensional model rendering system of the embodiment provided by the present invention, and the structure includes:

[0056] The parsing unit 201 is configured to parse the 3D model to be parsed into multiple components through a 3D model parsing tool.

[0057] In the embodiment of the present invention, a component is a basic unit of a three-dimensional model, and different three-dimensional models can be rendered by moving the component. After the terminal acquires the 3D model to be analyzed, the analysis unit 201 uses a 3D model analysis tool to analyze the 3D model to be analyzed into multiple components. Help for file parsing libraries such as Open Asset Import Library.

[0058] The sending unit 202 is configured to send the data of all components parsed by the parsing unit 201 to a graphics processor (Graphic Processing Unit, GPU) of the terminal through a three-dimensional graphics program interface,...

Abstract

The present invention is applicable to the field of three-dimensional display technology, and provides a three-dimensional model rendering method and system. The method includes: analyzing the three-dimensional model to be analyzed into multiple components through a three-dimensional model analysis tool; Send the data of multiple components to the graphics processor of the terminal; create a state linked list for recording the states of the multiple components; select the component through the collision of the interactive device, and obtain the first model perspective projection of the selected component from the state linked list matrix, and update it to a second model perspective projection matrix; determine the second model perspective projection matrix as a third model perspective projection matrix, and render the third model perspective projection matrix. Through the present invention, the interaction process between the three-dimensional model and the rendering in the process of splitting and assembling can be reduced.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional display, and in particular relates to a three-dimensional model rendering method and system.
