gSPZMtxCat
FormatgSPZMtxCat(Gfx *gp, u32 mids, u32 midt, u32 midd)Arguments
- gp is the pointer to the graphics display list
- mids is the matrix area S
- midt is the matrix area T
- midd is the matrix area D
This Z-Sort microcode GBI macro sets matrix D equal to the concatenation of matrix S with matrix T. Generally, GZM_MMTX, GZM_PMTX, or GZM_MPMTX is specified for the mids, midt, and midd arguments. However, the 128 bytes at the head of the user area can also be used; if so, specify GZM_USER0 and GZM_USER1 to use address 0-63 at the head of the user area and address 64-127.
When the matrix T and D areas are the same, the operation may not work as expected. There is no problem when areas S and D or areas S and T are the same.
For detailed information on Z-Sort microcode's GBI macros and data structures, please see the "Z-Sort Microcode" area of the N64 Programming Manual.
