Does Crystal Space use Direct3D?

No, Crystal Space works with OpenGL (or software rendering) on all platforms.

Which version of Crystal Space should I use?

In almost all cases you should use the last stable release (1.0 in this case). This is the version that we tested and fully support. However, if you depend on new features that are only present in the latest development version then of course you are free to use the 1.0 development version as well. But keep in mind that this version may break from time to time and we will not be able to support you as effectively if that happens.

Do I need a C++ compiler to use Crystal Space?

Yes and no. To use the basic Crystal Space and Crystal Entity Layer source packages you need a C++ compiler. You will also need a C++ compiler to compile your own project sources. However, you can also use CELstart which is a precompiled application that contains Crystal Space and Crystal Entity Layer. And using CELstart you can make applications with Python or XML without the need for a C++ compiler.

When can I use CELStart?

Use the CELstart project if you want to make a fully scripted Crystal Space game (either with Python or XML scripts, or both). If you want to use C++ then you should use the normal Crystal Space (and CEL) packages.


Is there a free C++ compiler available for Windows?

Yes, you can use the free (as in speech) MingW compiler on Windows. To download MingW you need both the full MingW package and also MSYS. You can download both from this location.

Microsoft also distributes a free (as in beer) version of their Visual C++ compiler and IDE called Visual C++ 2005 Express Edition which is completely sufficient to build and develop with CS. The manual contains [/docs/online/manual-1.0/cs_2.4.2.php build instructions] for this compiler.

I'm using the Visual C++ 2005 Express Edition and I get a lot of errors. What is wrong?

Errors like windef.h not being found, or some SH... symbol being unresolved on linking indicate a lacking or an incomplete installation of the Platform SDK. Exactly follow the instructions given here: [1]. Also, the instructions don't say that, but if you have Visual C++ open while applying those changes you need to restart it.


How can I make maps and models for Crystal Space?

One of the best supported solutions for making maps is Blender. Using the powerful blender2crystal script for Blender you can export directly to Crystal Space and Crystal Entity Layer from within Blender.

Included with Crystal Space there is also an exporter script for 3dsMax. This is also well maintained and supports a lot of features in Crystal Space.
