Detailed Description

vtIcoGlobe is an icosahedral globe. To use it:

call Create() with the desired parameters to construct the object
call GetTop() to get the top node in the globe's scene graph
add that node to your scene graph

The globe has unit radius.

Member Function Documentation

void vtIcoGlobe::Create	(	int	iTriangleCount,
		const vtString &	strImagePrefix,
		Style	style = `GEODESIC`
	)

Create the globe's geometry and nodes.

Parameters

iTriangleCount	The desired triangle count of the entire globe. The class will attempt to match this value as closely as possible with the indicated tessellation.
strImagePrefix	The base of the filename for the set of icosahedral surface textures. For example, if your textures have the name "geosphere_*.jpg", pass "geosphere_"
style	Tessellation style, can be one of: GEODESIC A classic geodesic tiling based on subdividing the edges of the icosahedron and gnomonically projecting them to the sphere. RIGHT_TRIANGLE An alternative approach where each face is divided into right triangles recursively. DYMAX_UNFOLD Same as RIGHT_TRIANGLE but the faces are also placed on seperate geometries so that the globe can be unfolded in the Dymaxion style.

void vtIcoGlobe::SetInflation ( float f)

Set the amount of inflation of the globe.

Parameters

f	Ranges from 0 (icosahedron) to 1 (sphere)

void vtIcoGlobe::SetUnfolding ( float f)

Set the amount of unfolding of the globe.

Parameters

f	Ranges from 0 (sphere/icosahedron) to 1 (entirely unfolded flat)
