UE1 - UT SphereBuilder

[Gizzy]

In UnrealED 1 (Oh god.) There was a SphereBuilder tool (Similar to the Cube builder and such) but in UnrealED 2 it was replaced with the Tetrahedron builder. Thanks to the lack of BrushBuilder classes in any version other than 227, it's difficult for me to recreate this for 227.

I have the base of the class set up. Variables were copied from UnrealED 1. The comments are the gaps I need to fill

//=============================================================================
// SphereBuilder.
// A Sphere Builder from UnrealED 1
//=============================================================================
class SphereBuilder expands BrushBuilder;

Var() Float OuterRadius, InnerRadius;
Var() Int RadialSides, VerticalStripes;
Var() Name GroupName;
Var() Bool Hollow;

Function BuildSphere( /*Some stuff needs to go here*/ )
{
	// Maths junk here?
}

Function bool Build()
{
// Validity checks on the Sphere. 
	if ( OuterRadius <=0 ) 
		return BadParameters("OuterRadius must be larger than 0.");
	if ( InnerRadius <=0 )
		Return BadParameters("InnerRadius must be larger than 0.");
	if ( RadialSides < 3 )
		Return BadParameters ("Sphere must have at least 3 Radial Sides.");
	if ( VerticalStripes < 2 )
		Return BadParameters ("Sphere must have at least 2 Vertical Stripes.");
	if ( Hollow && InnerRadius >= OuterRadius )
		Return BadParameters ("The OuterRadius must be greater than InnerRadius.");

	// BeginBrush( false, GroupName );
	// BuildSphere( /*Probably need more stuff here*/ );
	// if ( Hollow )
		// Stuff to build a hollow sphere here
	// Else
		// Some more stuff.
	return EndBrush();
}

So can someone help me finish this?

What's wrong with the tetrahedron builder? And what's the difference, apart from being able to create hollow spheres? (Hollow objects could as well be created with two brushes.)

The way they are built is slightly different and SphereBuilder has more options like how many times to split it vertically or horizontally (Radialsides and verticalstripes)

It's a request someone made really, and I'm sure a few people would get some use out of it. (I'd like a new brushbuilder too....never had my own before )
