Detailed Description

This class extends vtTin with the ability to call vtlib to create 3d geometry for the TIN. It also subclasses vtHeightField so it provides the ability to do height-testing and ray-picking.

Member Function Documentation

bool vtTin3d::FindAltitudeAtPoint	(	const FPoint3 &	input,
		float &	fAltitude,
		bool	bTrue = false,
		int	iCultureFlags = 0,
		FPoint3 *	vNormal = NULL
	)		const [virtual]

Returns true if the point was over the TIN, false otherwise.

Reimplemented from vtTin.

bool vtTin3d::Read

(

const char *

fname

)

Read the TIN from a file. This can either be an old-style or new-style .tin format (so far, a VTP-specific format)
