calculateTangents

public void calculateTangents(Geometry geom,
                              TangentsFactory.TangentsStoreMode storeMode,
                              int storeIndex1,
                              int storeIndex2,
                              org.openmali.vecmath2.Vector3f[] tangents,
                              org.openmali.vecmath2.Vector3f[] bitangents)

Calculates the tangents and bitangents for the given GeomContainer. The GeometryArray must have at least three texture units where the first one (0) must be filled. It also has to have normals.
If both of the two array parameters are null, the tanget data is directly applied to the 2nd and 3rd (1, 2) texture units.

Parameters:

geom -

storeMode - use null to only store in the arrays (index1 and index2 are ignored then)

storeIndex1 -

storeIndex2 -

tangents -

bitangents -

calculateTangents

public void calculateTangents(Geometry geom,
                              TangentsFactory.TangentsStoreMode storeMode,
                              int storeIndex1,
                              int storeIndex2)

Calculates the tangents and bitangents for the given GeomContainer. The GeometryArray must have at least three texture units where the first one (0) must be filled. It also has to have normals.

Parameters:

geom -

storeMode -

storeIndex1 -

storeIndex2 -
