S3GE Console: Creating a Sphere on the fly.
There are many ways you could go about it. I'll tell you how I do it. S3GE uses
LUA for all scripting
and a home-grown GUI System which uses a Markup Language (S3GXL) to create Gizmos such as a Textboxes, Buttons, etc:
<!-- Engine Console -->

LUA features a fast interpreter for on the fly execution ideal for a console.
You'll have to write glue code to bind LUA to your C++ code, then use a GUI to load and execute LUA text.
inline int darklua_luaScriptExecute(lua_State *L){if(lua_gettop(L) < 3){lua_pushstring(L, "Error! < 3 arguments"); lua_error(L);}DARKLUA_RETURNSTRING(DarkLUA::System::Execute(DARKLUA_STRING(1), DARKLUA_STRING(2), (char*)DARKLUA_STRING(3)).c_str()); return 1;}
I've had to bind 1000s of functions. The current console is very rudimentary, but, at least uses a GUI. There is a little work involved and I'm certain the snippets of code may not make much sense alone.
