Hello
I written another example about 3D with translation 
Have Fun!! |

how to use dwords as integers,
and convert integers into fp? add integers to fp? imul fp with integers? idiv fp with integers? |

Quote: convert integers into fp? Code: FILD [Variable] FPU automatic convert in float point. Quote: add integers to fp? Code: FIADD [IntegerVariable] FIMUL [IntegerVariable] FIDIV [IntegerVariable] |

for exemple :
int 1000->fp 10^3 int 1->fp 1 it works????? in this case i'll try to make fp computation in my engine. it's in 32 bit fixed point and does have a limit that is a bug. |

Please post some code or some formula,
i show you an example computation with FPU |

WOw.. Nice job.. Didn't even know that kind of stuff could be created in asm, but then again I have never tried any 3D graphics.. Have fun

Cool juggling like effect with the balls - kind of seem like they are sliding on an imaginary glass surface. Can't wait to see what you can do with more colors.

I mean simply formula to show you use of FPU ,not whole programs 
I don't have time to look at your source |

hé hé the use of fpu is at 3dobject.inc

OK
you first must decide if use integer or float point,then only instruction that you need are: Code: FILD [integerVariable] ;load integer variable from memory FLD [floatVariable] ;load float point variable from memory FIMUL [integerVariable] ; mutiply st with integer variable in memory FMUL [floatVariable] ;multiply st with float point variable in memory FIDIV [integerVariable] ;divide st with integer variable in memory FDIV [floatVariable] ;divide st with float point variable in memory FSINCOS ;cos ST sin ST FIADD FADD FISUB FSUB FLDPI ; load constant PI FLDZ ; load zero FLD1 ; load 1 etc... Note that you can work with FPU stack,with more speed Why you don't learn some FPU stuff like this? http://www.website.masmforum.com/tutorials/fptute/index.html |

fsincos is based on PI?
thanks i'll try i need finit? all fp instruction push / pop the fp stack; thats why i didn't use it. |

grrrrr it's hard to code with fpu
i never know where are my datas. it's buggy,each time i add a fpu instruction, my program becomes more buggy. nothing appears now! i'll see that very later! |

Quote: fsincos is based on PI? FSINCOS is based on Angle in radian loaded on ST Radian = Degree*PI/180 Quote: i need finit? Only at start for init Coprocessor Quote: all fp instruction push / pop the fp stack; thats why i didn't use it. 
What is the problem with FPU Stack? |
