Detailed Description

template<class T> class sglTriStripper

Grouped by material state.

To make for efficient processing all faces with the same material type are grouped together. This class contains the repository for a single material definition and all associated face data (vertex, normal and texcoord indices). It also contains the function used to convert the triangle face data into more efficient triangle strips.

Member Function Documentation

template<class T> unsigned int sglTriStripper<T>::getNumTriangles ( ) const [inline]

return number of triangles loaded. Definition at line 58 of file sglTriStripper.hpp.

template<class T> void sglTriStripper< T >::addTriangleFace ( sglTriStruct< T > * tri ) [inline]

sglObjModel passes absolute index list for current triangle (n-gons and relative indices are converted to triangles and absolute indices by the parser in sglObjModel Definition at line 299 of file sglTriStripper.hpp.

template<class T> void sglTriStripper< T >::computeFaceNormal ( const sglVec3f & v0, const sglVec3f & v1, const sglVec3f & v2, sglVec3f & normal ) [inline, static]

Computes the normal for the given triangle face. Definition at line 362 of file sglTriStripper.hpp.

template<class T> void sglTriStripper<T>::computeSmoothNormals ( const sglVec3f * verts, unsigned int(* addNormal)(void *,sglVec3f &), void * passThrough )

Computes smooth (not faceted) normals for vertices with invalid normal indices (UINT_MAX). As each normal is calculated the given addNormal function is called to compute its index.

template<class T> void sglTriStripper<T>::computeFacetedNormals ( const sglVec3f * verts, unsigned int(* addNormal)(void *,sglVec3f &), void * passThrough )

Computes faceted normals for vertices with invalid normal indices (UINT_MAX). As each normal is calculated the given addNormal function is called to compute its index.

template<class T> void sglTriStripper< T >::triStripify ( bool verbose = true ) [inline]

create tri-strips from the original triangle data. Definition at line 474 of file sglTriStripper.hpp.

template<class T> void sglTriStripper< T >::reset ( ) [inline]

reset the tri-stripper to the initial state. (allows the stripper to be used more than once). Definition at line 216 of file sglTriStripper.hpp.

template<> void sglTriStripper< sglVertStructV >::copyTriangleIndexLists ( unsigned int * index_vlist, unsigned int * index_nlist, unsigned int * index_tlist, unsigned int * index_clist ) [inline]

copy the index lists for the isolated triangles. Definition at line 925 of file sglTriStripper.hpp.

template<class T> unsigned int sglTriStripper<T>::getNumStrips ( ) const [inline]

get number of tstrips. Definition at line 105 of file sglTriStripper.hpp.

template<class T> vector< T > * sglTriStripper< T >::getStrip ( unsigned int index ) [inline]

get a handle to each strip based on index. Definition at line 914 of file sglTriStripper.hpp.
