can someone give me a compact equation which i can use to project a 3-d object on to a 2-d plane? For example if i have a cube, how can i calculate the x,y co-ordinates of the 6 vertices on a 2-d plane when its rotated 360 degree, moved towards or away from the projection plane, etc. I want to use this formula to code a c# application. Please help me!

Just wondering if anyone uses IaaS (I guess Amazon EC2 would be the frontrunner) or maybe even PaaS?
What are the key things you look for in terms of services in either of the two? Perhaps region, price, or the services available?

From IaaS/PaaS perspective, you should look at the
1) Range of available Options : Is the infrastructure providing faster computing resources OR storage OR database services OR a combination of many.
2) Pricing : Fixed Pricing or Pay as you Go. Later being the best.
3) The current trend of incoming and outgoing traffic of the provider: Most chosen by customers or not.
4) SLA : On the situation of an outage, what is their policy? Refund ? History of outages ?
5) Scaling systems in place : Are load balancers installed by the providers which keep the service instances always up.

What is Cloud Computing???

Why not try this[^] first?
One of these days I'm going to think of a really clever signature.

Business applications are moving to the cloud. It’s not just a fad—the shift from traditional software models to the Internet has steadily gained momentum over the last 10 years. Looking ahead, the next decade of cloud computing promises new ways to collaborate everywhere, through mobile devices.
|
|

|

the idea with cloud computing is to have all of your application and your files on the internet (the cloud).
This way you have some advantages:
-it should be less expensive since you don't pay for maintenance of your own server, you only pay for what you need when you need it (you can choose how much resource you want to pay and you can scale it up easily)
-you can have your application and files everywhere you go, on whatever device you find
-you're granted with a really high up time and high security
The are disadvantages:
-You have to be connected to the internet
-you don't have any control over security

From my point of view, this could be in the advantage column as well as in the disadvantages.....
|

Well yeah it may be an advantage if you don't want to create some security service or buy an external service, or if you do want to have a custom service but don't know what the hell you're doing 
|
|
|
|
|
That's what I meant. Maybe I would add that it might also be an advantage for all those who "think" they know what they are doing, but don't....

Well you can try a Google search for open source projects that offer solutions to your problem, or you can write some code. Though I do not see what this has to do with Cloud Computing.

Do you think anyone would trust their data to be safe with a company that relies on spam for advertising? This is the fastest way to loose customers.
I suggest you change the name of the company, as the damage is already done.

You should never need to create a new database based on new users resgistering.
I suugest that you look at your databade design.
However if you really need to do this you will probably have to script it on the database server.
What type of database are you talking about here? mySQL, SQLServer ...?
You could for example get your code to write a dynamically generated script file to the server and then run it to create your required database.
Kind Regards

Hi,
I try to transfer my database from sql server 2008 to sql azure but the all ways failed until this time.
Please help me.. How I can transfer a database (Schema script + Data) from a local sql server 2008 to sql azure.
Thanks alot

SqlAzure Migration Wizard[^] is a pretty handy way to do it. You may need to convert your database to SQL 2008 R2 before using it.
