gSPZMixS16
gSPZMixS8
gSPZMixU8
Format
gSPZMixS16(Gfx *gp, u32 src1, u32 src2, u32 num, u16 factor) gSPZMixS8(Gfx *gp, u32 src1, u32 src2, u32 num, u16 factor) gSPZMixU8(Gfx *gp, u32 src1, u32 src2, u32 num, u16 factor)Arguments
- gp is the pointer to the graphics display list
- src1 is the start of address 1 in the user area that holds the data to be interpolated, and it is the starting address in the user area where the interpolation results will be placed
- src2 is the start of address 2 in the user area that holds the data to be interpolated
- num is the number of data element (a multiple of 8)
- factor holds the mixed factors (u.15 format 0x0000-0x7fff value)
These Z-Sort microcode GBI macros perform linear interpolation on two numbers using the following formula. The s16, s8, and u8 data types are handled by their respective GBI.
(*src1)=(*src1)*factor+(*src2)*(1.0*factor);In gSPZMixS16, src1 and src2 combined are limited to 16 bytes. In gSPZMixS8 and gSPZMixU8, src1 and src2 combined are limited to 8 bytes.
The num value must be a multiple of 8. If a number that is not a multiple of 8 is specified, meaningless data is returned to src1 until the number becomes a multiple of 8.
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.
