Problems solved by technology

[0003] Currently, XNA technology only supports two 3D model file formats, .x and .fbx, which makes XNA technology too dependent on the model file format when developing a 3D model display system, which reduces the versatility of XNA technology

Embodiment Construction

[0020] Such as figure 1 As shown, a kind of three-dimensional model file format conversion method that supports XNA technology described in the present invention, comprises the following steps successively:

[0021] A: Preprocess the 3D model file to be converted, delete duplicate points, duplicate lines and duplicate surfaces;

[0022] B: Determine the type of the 3D model file to be converted. If it belongs to the .x and .fbx file format, go to step D; if it belongs to the .3ds, .skp or .dae file format, go to step C; if it does not belong to the above file format, Then go to step E;

[0023] C1: Perform data analysis on .3ds, .skp or .dae file formats, read the main block information of the 3D model file to be converted and the two first-level blocks under the main block information, and the two first-level blocks are respectively the main editor block and key frame block, skip if the key frame block is read, and continue to read the main editing block; if the main editin...

Abstract

The invention discloses a three-dimensional model file format conversion method supporting an XNA (WindowsXbox, Next-generation and Architecture) technology, which sequentially comprises the following steps of: A, preprocessing a three-dimensional model file to be converted and deleting repeated points, repeated lines and repeated surfaces; B, judging the type of the three-dimensional model file to be converted, entering the step D if the type of the three-dimensional model file to be converted belongs to .x and .fbx file formats, entering the step C if the type of the three-dimensional model file to be converted belongs to a .3ds, .skp or .dae file format, and entering the step E if the type of the three-dimensional model file to be converted does not belong to the file formats; C, carrying out data analysis on the .3ds, .skp or .dae file format and storing data obtained by analysis according to a universal storage structural .fbx format; D, finishing the converting process and prompting a user that the three-dimensional module file to be converted does not need to be converted or cannot be converted. The three-dimensional model file format conversion method can improve universality of the XNA technology and also has the advantages of improving the speed of processing the model file and ensuring stability of a data model.

Description

technical field [0001] The invention relates to a file format conversion method, in particular to a three-dimensional model file format conversion method supporting XNA technology. Background technique [0002] XNA technology is based on DirectX and further encapsulates it, repackaging the hardware functions of the graphics card, providing an API that is simpler than DirectX and dedicated to C# programming. On the three platforms of personal computers, game consoles, and mobile devices, complex games or applications can be realized quickly through XNA technology. The existing XNA 4.0 version has integrated the game development environment of the computer, Microsoft's Xbox game console series and the Windows Phone7 mobile device development environment, using the game or application program developed with the C# language and XNA architecture, as long as a slight modification, you can Runs on all three platforms at the same time. [0003] Currently, XNA technology only suppo...
