"Simple DDA" does not require special skills for implementation.
These two algorithms are almost completely different. The only real similarity is that they are each designed to use only integer addition/subtraction and multiplication, avoiding expensive division and floating point operations.
1.It drift away from the actual line path because of rounding off float values to integer2.It causes jaggies or stair-step effect----------------------------------------------------------------------------------------------------------------Disadvantage:The accumulation of round of error is successive addition of the floating point increments is used to find the pixel position but it take lot of time to compute the pixel position. ----------------------------------------------------------------------------------------------------------------More Informationhttp://knol.google.com/k/thiyagaraaj-m/dda-line-algorithm/1lfp8o9xxpx13/78# http://i.thiyagaraaj.com/articles/articles/dda-line-algorithm----------------------------------------------------------------------------------------------------------------the standard version of dda given as in one of its steps asif(abs(dx)>abs(dy)) steps=abs(dx);else steps=abs(dy);this part just supports the positive slop with starting point on left side. Take an example of any other end points as {(8,3) to (2,2) or (4,5) to ( 8,2) or (8,3) to (5,5) } where the slop needs to be negative( for the last two cases) only.can anyone correct me by suggesting the accurate version of DDA? Or is this the actual DDA??.

DDA stands for Digital Differential Analyzer. With that in mind, simple DDA just means that it is simplified.

The DDA is responsible for ensuring that disabled people are not discriminated against in the workplace, school, or housing. DDA stands for Disability Discrimination Act.

DDA stands for demand deposit account. It is a bank account in which you can deposit and withdraw money. A form of a demand deposit account is a checking account.
There are several numbers located on the bottom of a check. There is the ABA number and DDA number, The DDA number stands for Demand Deposit Account and is the same as your account number.

DDA stands for Demand Deposit Account. It is your deposit account. A term used widely in payments industry
Happys is not Welsh, hapus is 'happy', Newydd means 'new' Dda mean 'good/well'
Gaf i ... os gwelwch yn dda? = May I have ... please? (Please may I have...?)E.g.Gaf i hufen iâ os gwelwch yn dda = Please may I have an ice cream?Gaf i botel o gwrw os gwelwch yn dda = Please may I have a bottle of beer?
