Hello
Is it possible to make a 3D animation with C++, only by code???
Like a Character for a game??

Yes it is possible, but it is much harder than using a tool such as blender, than finding a way to import your models.

Sweet. Thanks. I know python is great for Blender but I'd like to try C++ for creating 3D animation.

What sort of thing are you planning to do?

A typical setup would be to use some sort of games engine library like Ogre3d or Crystalspace to import models which you create in blender. These libraries should provide the tools you need to import 3d objects created with blender.

If you want to go a little lower level, you could use QT to give you a GL rendering context, and then some separate library for parsing the 3d object files (or even try to implement something like this yourself, although it seems a waste of effort given that this work has already been done by others).

Once you have the objects in your program, you can manipulate them how you like, but be aware that they are going to be pretty complicated objects.

The lowest level approach of all is to use GLUT or a similar library which gives you a GL rendering context, and make any objects yourself.

An alternative approach is to use the build in blender game engine. You don't need to write any code for that at all, although you can use python scripting to add complexity.

Sound I have to use Blender and python then.

Learning blender is non trivial. It's got a huge amount of functionality, and it will take a long time to become proficient with it. I believe it's worth the effort if you are interested in 3d gfx. Especially if you want to make a living as a 3d artist.

Thanks. I'll try.
