Abstract

A method for generating a library of materials that can be applied to geometry in a graphics scene when performing rendering operations. The method includes generating a class file that includes material parameters representing rendering characteristics of a material class and generating a library root file that includes a reference to the class file. The method further includes generating a rendering implementation file for translating values of the material parameters into a format recognized by a particular rendering engine and generating a user interface file that includes at least one user interface configured to allow a user to modify the values of the material parameters. The method also includes linking the class file to the library root file, and linking the rendering implementation file and the user interface file to the class file. Advantageously, the library can be organized and updated more effectively when compared to prior art techniques.

Claims

1. A method for generating a library of materials that can be applied to geometry in a graphics scene when performing rendering operations, the method comprising:

generating a class file that includes material parameters representing rendering characteristics of a material class;

generating a library root file that includes a reference to the class file;

generating a rendering implementation file for translating values of the material parameters into a format recognized by a particular rendering engine;

generating a user interface file that includes at least one user interface configured to allow a user to modify the values of the material parameters;

linking the class file to the library root file; and

linking the rendering implementation file and the user interface file to the class file.

2. The method of claim 1, wherein the step of generating the user interface file comprises executing a software tool configured to create the user interface file.

3. The method of claim 1, wherein the step of generating the class file comprises executing a shader engine configured to define the material parameters included in the class file.

4. The method of claim 1, further comprising the steps of:

generating a preset file that includes a set of values for the material parameters for each of one or more presets, wherein each preset comprises an instance of the material class; and

linking the preset file to the class file.

5. The method of claim 4, wherein the step of generating the preset file comprises executing a software tool configured for translating between a spreadsheet file having a first format and the preset file having a second format.

6. The method of claim 5, further comprising the step of generating a preset file structure that includes one or more files that links the class file and the preset file.

7. The method of claim 6, wherein the preset file and the one or more files included in the preset file structure comprise Extensible Markup Language (XML) files.

8. The method of claim 1, further comprising the steps of:

generating a rendering implementation file structure that includes one or more files that links the class file and the rendering implementation file; and

generating a user interface file structure that includes one or more files that links the class file and the user interface file.

9. The method of claim 8, wherein the one or more files included in the rendering implementation file structure and the user interface file structure comprise XML files.

10. The method of claim 1, wherein the library root file, the class file, the rendering implementation file, and the user interface file comprise XML files.

11. The method of claim 1, further comprising the step of compiling the file structure into an executable file.

12. A computer-readable medium storing instructions, that when executed by a processor, cause a computer system to compile a library into one or more executable files, by performing the steps of:

receiving a library root file that includes references to one or more class files each having material parameters representing rendering characteristics associated with a material class;

parsing the library root file to determine a first reference to a first class file;

linking the first class file to the library root file; and

generating an executable file representing the library based on the linking between the first class file and the library root file.

13. The computer-readable medium of claim 12, wherein the library root file and the class file comprise XML files.

14. The computer-readable medium of claim 12, further comprising the step of linking the class file to a rendering implementation file configured for translating values of the material parameters into a format recognized by a particular rendering engine.

15. The computer-readable medium of claim 14, wherein the step of generating the executable is further based on the linking between the rendering implementation file and the class file.

16. The computer-readable medium of claim 15, further comprising the step of linking the material class file to a user interface file that includes at least one user interface configured to allow a user to modify the values of the material parameters.

17. The computer-readable medium of claim 16, wherein the step of generating the executable is further based on the linking between the user interface file and the class file.

18. The computer-readable medium of claim 17, further comprising the step of linking the material class file to a preset file that includes a set of values for the material parameters for each of one or more presets, wherein each preset comprises an instance of the material class.

19. The computer-readable medium of claim 18, wherein the step of generating the executable is further based on the linking between the preset file and the class file.

20. The computer-readable medium of claim 19, wherein the rendering implementation file, the user interface file, and the preset file comprise XML files.
