Hi, Benjy.  There are about 10 different approaches to this one so we need a little more info to choose the most appropriate one.

Is this a game or a business app (like a manufacturing prog where you need to see some part or component in 3d.)  Will it run windowed, full-screen, or both?  Do you just need to see the object from pre-set angles (0, 90, 180, 270) or from any angle the user selects?  Is this the only object, or will you be using this code to show any number of objects?  Will you need to zoom in/out on the object?

As you can see, the most efficient answer is dependent on a lot of factors.  Tell me more... it sounds interesting.

I would suggest using OpenGL to render 3D objects in VB.  OpenGL is easier to learn than DirectX, but it is not as fast.  However, there are some good sites providing tutorials and samples.  You would be most interested in Texture Mapping samples (a bitmap wrapped around a 3D object).

A good place to start is here:
"Programming OpenGL with Visual Basic"
http://is6.pacific.net.hk/~edx/contents.htm

You will probably need to download the OpenGL support DLLs which can be found at this site.  There are also tutorials and samples, especially note the Texturing samples link.

Good luck!

i agree that OpenGL is easier to learn.  i would recommend the "red book" called the OpenGL Programmer's Guide

Do you already know how to create and rotate and view objects by using regular old-fashioned methods??  Also, are you OK with using matrices and other mathematical things?

Hi,
I apologize for taking so long to respond to your comments. I really appreciate your very prompt reply and as gratitude I am doubling the points.
My project is to simulate how a knit cap will look using a certain pattern. the pattern is basically a grid with values representing colors, that repeats itself. I just want the user to get the best picture he can of how it will look, It would be nice to be able to rotate it, but a side view and a top view will do. I am looking for the easiest way to do this, I don't mind if it will use mathematical functions as long as they are clear and strong enough to perform the task. If there is an ActiveX control that can do it automatically I guess it is preferable.
the cap I am referring to is basically like a knit Jewish yalmica, if that helps.

Hi question-asker!

You seem to be experiencing some difficulty with this site.

Experts-Exchange is not a news group, in which you can post a question, get the answer, and walk away, or ignore any posts that do not serve to solve your problem.

You can read more about how the site works in our member agreement: http://experts-exchange.com/jsp/infoMemberAgreement.jsp

Although the agreement tells you something about how the site works, it doesn't tell you much about the netiquette that has evolved on our site. In Experts-Exchange it is expected that you always provide feeback to those who participate in the questions that you post. And I'll explain why this is the case.

When a question is resolved, it becomes a Previously Answered Question (PAQ), and will be stored in the database. Users who have similar problems can buy your question for 1/10 of the original point value in order to find a solution to *their* problem.

As a result it is important that you provide feedback to our experts. If their suggestions do not work, tell them why. If they do, award them by grading the answer so that the question does indeed become such a "PAQ".

That way future visitors of this question get the most out of it.

I would also like you to consider this: Our experts are willing to spend some of their precious time to help you solve your problem. A lot of our experts are professionals, to whom time is money. And they're willingly giving up some of their time to help you.

And the only thing we're asking in return is a bit of feedback and an effort on your behalf to participate according to our member agreement and our peculiar brand of netiquette. I think that is a pretty good deal, don't you?

If you were the last to make any comment to this question, or placed a delete request that was not processed, please leave a comment what to do with the question.

If any of the participating experts want this question to remain open or does have a reason to let it be graded/closed by a moderator, please leave a comment.

If no expert participated in this question (e.g. there are no comments at all), just ignore this message. Your question will be deleted and your points will be returned. If you don't want this, just leave a comment.

Thanks!

 

by: JonFish85Posted on 2001-09-05 at 11:21:05ID: 6458213

thanks for closing the question, and especially for giving an A grade!
