使用OpenGL使用C ++制作3D橱柜图像

Question

I have to draw cupbaord image like below using visual studio c++ by using OpenGL and I dont have much of an idea on how to do this. Where should I start?

Answer 1

Lets assume for a short moment that the cupboard should be 2 dimensional (I cant believe that your teacher wants you to start 3d development without giving you an introduction first). This simplifies things alot. While you could also draw 2d shapes with OpenGL or DirectX I wouldnt recommend you any of those frameworks, as these have a steep learning curve especially for a beginner.

It would have been nice to know, whether you (and your class) have worked with a specific GUI framework before. If not Im afraid to tell you that you will have to get into one. QT is one of the most commonly used in C++ and I would advice you to you this one, as it provides a clean abstraction and you wont have to deal with kind of lowlevel functions like they appear in win32.

Nonetheless which one you choose, nearly every has some component allowing you to draw arbitrary (2D) stuff. In QT this is done by implementing a custom Widget. Here is a tutorial on this matter: http://www.informit.com/articles/article.aspx?p=1174421&seqNum=2

As I assume that your cupboard should actually be a more or less fancy grid I can assure you that this is kind of simple. A little hint: rectengular polygons and for loops.

Answer 2

I weakly recommend the classic 'NeHe' tutorials http://nehe.gamedev.net/ they demonstrate some poor code but do the job and are popular enough that you can find help with them specifically

Tackle it like any problem too... you can make an app? so you know you need an entry point, right? You want to show an image? Load it into memory etc.... google become much more helpful for those kinds of targeted problems. :)
