how to a line between two points??

Thread Solved |
hi again ..
Does anybody have any idea how could I draw a line between two points using assembly language?
e.g. if you have the first point DX1, CX1 and DX2, CX2...
I wanna draw a line between them, simply, I wanna program that I give him two points and then he draws a line between them.
I prefere the program to be simple too
.. Thanks

how to draw a line depends on the operating system. If you are using MS-Windows you can use the win32 api graphics functions. If you are in MS-DOS you could probably just use a line drawn with dashes, in a loop of some sort.
Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
Thanks guys, however you might not get my point. I'm using MS-DOS, TASM program to write my assembly programs, windows xp.
I think most of you know the INT10H function AH = 0CH, while AL = color value and before that we choose graphics mode INT10H AH = 12h. Interrput INT10H AH = 0CH and AL = 02 for green dot. it simply draws a pixel in the screen 640*480, while you specify CX for columns and DX for rows. My problem is how could I join two points with a straight line for example CX1,DX1 and CX2,DX2. You know it's too hard to use math equation I have to define many things. So, if you have another way rather than using math equation I'll be happy to have it..
Thanks again guys

Use the link I posted.
Calculate a series of XY positions that get you from the start to the end.
For each position, call INT10H function AH = 0CH, with the other registers set to the colour and position you want.
It's just a bit of maths, and a loop calling INT10H. What more do you want?

I can't implement bresenham algorithm on assembly. It's too hard to do so. because of many things, first pixals are integers number and it's hard to manipulate them. Second, in assembly you don't have math library.
I don't wanna draw each line that is representing first second, second second, third second and so on. Also the same for minutes and hours. I tried to implement bresenham algorithm but it didn't work.
So if you see that too easy to implement it please do it for me ..
Thanks in advance.

> I can't implement bresenham algorithm on assembly. It's too hard to do so.
So give up already and go back to doing things in a high level language if you can't deal without all the creature comforts.
Assembler programming can be damn hard work at times, and you have to occasionally do every little thing yourself.
I mean, what would you do if the INT10 function was not available, and you had to do all the address arithmetic to work out the memory location for a pixel. Could you manage that?
> Second, in assembly you don't have math library.
Unless you write your own.
Read up on fixed point arithmetic if you're worried about fractions.
There's also an integer version.

But that requires some reading on your part as well, so perhaps it's not such a good idea.

Well posting it might at least help convince some of us that you're pulling your weight around here, and not just looking for free handouts.
Don't forget to comment it thoroughly, and remember to use the [code][/code] tags if you do decide to post it.

While you get all the credit?
And what happens the next time you have a problem, will you be back cap in hand looking for more free handouts?

Listen tough guy, I did the project without any help. However I am trying now to reduce the size of the code.
This is my code and it's 122KB ...
I don't think so there is someone can solve like this. The project is analog clock.
