when posting questions like this, please give us some more information about your system such as windows version.

if you want the short answer, you can't, or at least not directly. There are two ways to do this.
1. create a new sphere
2. duplicate the old sphere in object mode, and then do your cutting

you don't have opengl installed/it's not working. You need to make sure that you have either the accelerated graphics drivers installed, or that you have MesaGL. I can't tell you much more, unless you tell me what kind of system you're working on.

do you have all the image libraries installed, such as libpng, libjpeg, libtiff, etc. It might be a good idea to install blender via apt, that way you can be sure that you have all the dependencies:
and then run the blender that you downloaded off the website.

I don't know if this would be classified as a bug, a feature request, or just a part of the program that's not well written. The blender command line is one of those features that not many people use, except for those of us who are trying to write distribued renderers. Anyway, I have recently discov...

I've built the cvs/orange version of blender, and when I open my current project and click the new "render layers" tab blender crashes with a memory fault. This doesn't appear to happen on any of my other .blend files, but only on this one.
Specs:
Ve: 692432
Mem: 60.62Meg

what should I do?

One other little note, this also happens with the new render system under the orange cvs branch

You may not be missing the openexr lib, but you may be missing the development headers for openexr.

Here is an example image of what I am doing with the obvious errors circled. ther are more than I have circled, but this should give you an idea of what I'm working with.

Ok, I got my webspace working, so you guys can have a look at it: http://www.evertek.net/engedi/blender/test.blend Here's the render on blender 2.40 with X86_64: http://www.evertek.net/engedi/blender/test-2.40-x86_64.png Here's the render on blender 2.40 with i386 http://www.evertek.net/engedi/blend...

I would not clasify this problem as a "bug" simply because it does the same thing in blender 2.32 as it does in 2.4. and you will get slightly different results on different versions, and different archetectures. the .blend file is comming, but I need to get my webspace working so that I can upload ...

If you are experienced with blender you have probubly notaced this. if you have two parallel faces, sometimes the render will do weird things, such as render half of the front face, and half the one behind it. or it could cause the front face to cast shadows on the back face, but the back face is th...

the main reason is that blender and YafRay are completely different engines, developed differently, and by different people. the blender internal render engine is the same render engine as has always been in blender, but yafray export support is relatively new. when you render with yafray you are ex...

Is there any chance we could get a live python terminal in blender, so that you can test code using the blender python functions, without running a script.

I'm having problems building the orange branch on my amd64 machine: source/kernel/gen_system/GEN_HashedPtr.h: In member function ‘unsigned int GEN_HashedPtr::hash() const’: source/kernel/gen_system/GEN_HashedPtr.h:43: error: cast from ‘void*’ to ‘unsigned int’ loses precision would someone like to f...
