    What does 'indices' mean?

    indices = (plural)index;//?

    What does this mean exactly?
    The following structure holds both the indices for the triangle's three vertices (meshIndex) and the indices for the three texture coordinates needed to texture a triangle (stIndex)
    typedef struct {
    unsigned short meshIndex[3];
    unsigned short stIndex[3];
    } mesh_t;

    Both indices here probably mean the x-coordinate and the y-coordinate of the vertices of the triangle.
    Indices are how we refer to different elements in an array.
    First hear, then understand, and then, leaving all distractions, shut your mind to outside influences and devote yourself to developing the truth within you.
