We know we have it since we made it this far.

Look for elements in ELEMENT block.

All elements are of the form: "<E ID="#"> ... </E>", with ? being the element type. Read the ID field first.

Since all edge data is one big text block, we need to accumulate all TINYXML_TEXT data and then parse it. This approach effectively skips all comments or other node types since we only care about the edge list. We cannot handle missing edge numbers as we could with missing element numbers due to the text block format.

Now parse out the edges, three fields at a time.

We know we have it since we made it this far.

Look for elements in ELEMENT block.

All elements are of the form: "<? ID="#"> ... </?>", with ? being the element type.

Read id attribute.

Read text element description.

Parse out the element components corresponding to type of element.

Create arrays for the tri and quad faces.

Fill the arrays and make sure there aren't too many faces.

Make sure all of the face indicies could be read, and that there weren't too few.

We know we have it since we made it this far.

Look for elements in FACE block.

All faces are of the form: "<? ID="#"> ... </?>", with ? being an element type (either Q or T). They might be in compressed format and so then need upacking.

See if this face has curves.

Create a TriGeom to hold the new definition.

See if this face has curves.

Create a QuadGeom to hold the new definition.

Read id attribute.

See if this face has curves.

Read text element description.

Parse out the element components corresponding to type of element.

Create a TriGeom to hold the new definition.

Create a QuadGeom to hold the new definition.

Keep looking
