user: You are replying to All about "normal vectors".

Write your reply.

assistant: this is to do with 3d asm programming
normal vector is used to hide planes from view
i was just wondering how one can make modifications to normal vector
calculation routine to take into account the modification of the x and y
coordinated by the z coordinate
in english this means (highly simplified model)
screen x = calculated x / z
screen y = calculated y / z
now if i use z the disapperance of planes will not be 'synchronised' with
what is shown i.e. while the normal vector is correct what is shown is
different to what would be shown if z wasnt used and normal vector isnt
calculated with z in mind so having come back full circle just how the hell
can i get z involved with vector calculation
technical bit follows
my 3d representation equations are
screenx = perspective * screen x /(z + zoffset) + xoffset
screeny = perspective * screen y /(z + zoffset) + yoffset
and the normal vector calculation is
done using cross product of the two vectors that define a plane
those vectors being a1,a2,a3 and b1,b2,b3 in the x,y,z order
e.g normalx(i)=a2b3-a3b2
    normaly(j)=-(a1b3-a3b1)
    normalz(k)=(a1b2-a2b1)
by now u probably realise that if there are any modifications made to x or y
coordinates of the object by division or multiplication (addition and
subtraction are ok) then the planes will seem to be eliminated/appear little
early or little late and obviously if we didnt modify x and y by division and
multiplication by (z+zoffset) and perspective respectively (haha) (if we dont
want perspective) then the planes would be eliminated and shown at the right
times! so thats what i have resigned myself to for time being which is to use
highly simplified equation which means i cant use z coordinate at all for the
depth feel goddamnit!
something else:
also negating z doesnt flip the z axis this is a response to some earlier
post to me and i dont remember the guys name u have to negate the x and y as
they are calculated /rotated

It is a question that was/is and will be discussed in all 80x86-assembly
related newsgroups.
Most ppl relay on that the boot-code is started at 0:$7c00. Only a few are
sure this will be happend at $7c0:0. Most boot-code I have seen does not
care about and sets DS,ES,SS to where it needs it and uses relative jumps
only. But some code indeed needs to be DS=ES=SS=CS=0 on starting to work.

Keep a linear frame buffer in main memory instead of video memory.
main memory is much faster to do all your image processing.
Use an interrupt routine to periodically (about 30 times/second)
copy the frame buffer to the video board.
Computers have become fast enough nowadays to tackle the problem this way.
