3D Interactive Environment in C#! Is it possible?

Hi
I'm a 3rd year Software Development student, and for our 3rd year projects we need to create our own piece of software, which will be judged and marked throughout the year.

Our group decided on an interactive 3D environment. The main focus of our project is going to be furniture manufacturers. We want to allow them to use our program to model their own furniture, and customize them as well e.g. adjust the length and width of table legs, chairs, tables etc. We also want to integrate cost calculation, which must be dynamic, in other words the price must change as the user adjusts the dimensions.

I want to know, is this possible? Or should we start looking for other ideas.
Will users be able to work with pre-rendered models(created in TrueVision3D or any other 3D modeling application) and modify them to their liking?

Any help will be appreciated.

Thanks in advance

C# has access to Managed DirectX, so also Direct3D. Using it you can render almost everything. If there are classes that support TrueVision3D files I can't tell.. you might need to create them yourself or use a different file format.

Don't try it, just do it! Wink | ;-)

I'll be honest, 3D programming is something I haven't done before, so please be a bit more specific. What do you mean by 'access to managed DirectX & Direct3D'? How do one go about using those?

They are installed with the DirectX SDK. If you haven't done 3D programming before, then you might just be biting off more than you can chew with this project. It's not something that you can pick up quickly - 3D is one of the most demanding areas you can work in.

You may have a look at the XNA-Framework,

i think its a little bit easier then plain DX coding.
If you don't want to have so much trouble with 3D programming and your models are only a view simple sprites, then have a look at GDI+. I already saw some good "3d" charts with it.

It's possible - but may be overly complex ... however you might ant to look here[^]

It could be a fun project, though - and one that can be split between a number of developers quite successfully (someone can concentrate on the display of the object, someone else on the user interface (rotating, scaling etc) another on the calculations... then at least, for example, if the 3D display proves too hard before marking time, window can display the dimensions as text.

The 'real world' issue, to my mind, is tying a specific 3D model to some sort of generic display routine; e.g. a table with four legs vs a stool with three, one with a round top the other rectangular...

I did some more research, and it seems that we're going to have to create a CAD application using C#, using additional CAD components.

Hi,
I have developed an application windows forms. I need to place at the top portion an area for banners. The data for banner will be on a web server it can be any type of data. I have tried an swf file but it didn't work.
I have used
axShockwaveFlash1.LoadMovie(0, "http://www.youtube.com/watch?v=soVQcF_ZxpI");
axShockwaveFlash1.Play();
If you suggest to use swf file I will have an xml file at server that will return a number of urls like above. A url will be selected randomly and will be played.

If some other technique is better I am ready to use it as swf is not the requirement but on clicking the banner should open a url.

Looking forward for your reply.
Please its urgent.
Thank You.

I've done something similiar with a WebBrowser control. It actually is the IE browser control hosted in you app, so it's quite powerful. The only thing you should be sure of is making your ad webpages small enough to fit fine in the control in your form. But that shouldn't be hard.

In my use of the WebBroser control, I do two things: set the AllowNavigation property to false, and remove the target of all FORM tags in the HTML during the WebBrowser's DocumentCompleted event. This is to disallow users from navigating away from the ad. But in my case, some users can specify the URL to display there, so that's just an extra layer of protection. If you totally control what will be displayed in your control and you don't put any links in your pages, you can skip this.

MySql is not putting the newline character(s) in. It's more likely that your not properly massaging and validating the data beofer your send it to be stored in the database.

Hi,

i get list of IVSSVersion object. after that i run a loop on it to get the version number, name, user etc. but i also need to show the checkout information for the particular checkin. for an example, if i checkout ver 3 and check in it as version 4. again i checkout ver 3 and checkin it as version 5. now in the report i need to show like that,

Checkout version, user, check in version
3,Jon,4
3,Jon,5

VSSItem vssItem = vssDatabase.get_VSSItem(sPath, false);
List<ivssversion> lstVersions = new List<ivssversion>();
foreach (IVSSVersion vssVersion in vssItem.get_Versions(0))
{
   lstVersions.Add(vssVersion);
}
foreach (IVSSVersion version in lstVersionDateRange)
{ 
    listviewitem.SubItems.Add(??????????); // need to add checkout version number
    listviewitem.SubItems.Add(version.Username);
    listviewitem.SubItems.Add(version.VersionNumber.ToString());
}
</ivssversion></ivssversion>

Thanks in adv.

or have a look on SLP-Services (Software Licensing Protection) or something like that.
With this, you have 2 great opportunities:
- encrypt special parts of your code
- protect functionality with lincence

negative part is the costs.

The best way, is to write them in C++. An obsfucator that will truly protect you, will cost a fortune, and all it does is protect your source. To stop people copying your app you need a licensing system that involves using the web to count how many machines a licence has been used for.

First of all, C# cannot target building an ActiveX component. It can make something that looks and acts like one, but isn't a true ActiveX.

Which brings me to the question. Is this component attributed to be exposed to COM?
