terrain

hi i am using a terrain that has been rendered using polygon meshes. i would like to learn how to move from e.g. one triangle to another, using to function/math peramiters…
void nextFace(CGPolyMesh *m, int faceIndex, int edgeIndex),

and
void faceStrip(CGPolyMesh *m, int faceIndex, int edgeIndex)

as you move to each triangle it lights up in colour.

thanx

how are you inputting the thriangles? how are you storing them? you talking about a step by step walkthrough of every triangle you render? sorry. not too clear on the question…but i am hungover…
