m3_viewer Star Craft 2 build 0.01.

I upload some tool to view .m3 mesh. I'll plan add converter to .obj file format. You can download binary file's from download_link .

struct M3VertexBlock

{

    D3DXVECTOR3 position;

    short value[12]; // array of unknown values. I try cast it's to normal and texture coordinates, but does't work. 6,7 - are texture coordinates /2048.

};

struct M3Header

{

        char id[4];// id for file format.

        uint32 tagsOffset;// offset to array of the tags.

        uint32 nTags;// number of tags.

        uint32 unknownValue_01;

        uint32 unknownValue_02;

};

struct M3Tag

{

        char tagName[4];// name ot the current tag.

        uint32 blockOffset;// offset reference to the block with some data.

        uint32 blockSize; //  count of the block.

        uint32 version;

};

void ReadFile(char* name)

{

         char *fileData;

         ifstream inStream;

         fileData= new char[fileSize];

         inStream.read(fileData,fileSize);

         inStream.close();

         M3Header headed;

         memcpy(&header, fileData, sizeof(M3Header));

         tags = (M3Tag *)(fileData+ header.tagsOffset);

         unsigned int nIndicesM3 = 0;

        {

                if( tags[i].tagName[2] == '8') && (tags[i].tagName[3] == 'U') // __8U - reference to vertex data.

               {

                      nVertecesM3 = (tags[i].blockSize)/sizeof(M3VertexBlock);

                      vertexBlock= (M3VertexBlock*)(fileData+ tags[i].blockOffset);

               }
