◆ asx3d3_tin_size()

static size_t asx3d3_tin_size ( const LWTIN tin,
char *  srs,
int  precision,
int  opts,
const char *  defid 
)
static

Need to make space for size of additional attributes, the coordIndex has a value for each edge for each triangle plus a space to separate so we need at least that much extra room

3 is to make space for coordIndex
