Design Log

Permalink 09:56:14 pm, Categories: Design Log  

On an administrative note, I realize that me placing the date in the title of my log entries is redundant, seeing as the blog system does this automatically. Thus, I am not going to do this anymore. You may think that my titles lack creativity, but I prefer to organize my thoughts this way, rather than continually trying to search through titles which may or may not have relevance to the actual text in the entry.

Anyway, I have updated the class diagram for the COLLADA conversion library. The changes I have made indicate design decisions I made to include the different steps of conversion as functions in a single class, rather than multiple classes. I have no idea why I originally designed it such that I had multiple classes for conversion - it really doesn't make any sense. This new method makes more sense. The diagram for it is shown below.


COLLADA Conversion Library Class Diagram rev2

I am still debating whether or not to make these functions private. In reality, they will probably only be needed internally by the class, but I hesitate to make them private in the interest of supporting applications which may only need to convert COLLADA geometry, or animation, etc... Thus, for now, they will be left as publicly accessible functions, although this may change in the future, depending on input from the community.

I have spent this morning creating Visual Studio projects and determining where in the CS codebase the COLLADA stuff will be located. I have entered most of my skeleton files (placeholders, really) into the CS codebase in the following locations (note that these are in my specific branch of SVN, not the trunk):

COLLADA Conversion Library:
   SCF Interface:          /include/iutil/collada.h
   SCF Implementation:     /plugins/colladaconvert/csColladaConvert.h
                           /plugins/colladaconvert/csColladaConvert.cpp
   Project File:           /mk/msvc71/plgcollada.vcprj

COLLADA Conversion Console Application:
   Header File:            /apps/colladaconvertor/appcolladaconvert.h
   Source File:            /apps/colladaconvertor/appcolladaconvert.cpp
   Project File:           /mk/msvc71/appcolladaconvert.vcprj

I wasn't absolutely sure whether the SCF interface file should go into iutil or not, although it seemed like a good choice. It can easily be moved, however, if other people feel it should be placed elsewhere in the codebase. I think that the other choices I made for locations were good, but feel free to comment on this if you feel it should be located elsewhere.

Also, it should be noted that these are simply skeleton files at the moment. They have some basic definitions and such, but are, for the most part, empty of functionality. Since I am still somewhat in the design phase, these will be populated with implementation as things progress. I will guarantee that they compile on my machine (a windows machine - hence the reason I am only populating the MSVC project files at the moment) each time I commit, but it is possible that they may not compile and/or have some difficulties on other platforms. I will rectify as many platforms as I can by the time the project is finished, but in the meantime, if you have a specific concern about it compiling on a platform other than windows while I am developing it, please feel free to comment on this blog, and I will see what I can do to accommodate any requests.
