New Features in TIN No initial image drawn when loading files. Simultaneous displays for 2 D and 3 D views. Volume and Export functions can hide display while building. (Much faster!) Sections function added. Export features: select X, Y and Z source. Modify channel and section files within TIN. Interactive editing of TIN.

New TIN Features – 2 D and 3 D Model 4 models to display: – wire frame – contour – fill – vertices Clone individual windows for different display options. Display multiple windows. Overlay contours, grid, channel and sections on each display. Save image to Geo. Tiff file (2 D). 3/9/2021 2006 HYPACK Training Seminar 3

Making a TIN MODEL from XYZ Data In this case study, we explain: – What’s a TIN MODEL? – How do you make a TIN MODEL? – What should you look out for when making a TIN MODEL? We’ll first make a model of the As 4 Before 20. XYZ file located in the Sort directory of the ‘Sample TIN MODEL’ project. 3/9/2021 2006 HYPACK Training Seminar XYZ Sounding data 8

What’s a TIN MODEL? TIN = Triangulate Irregular Network: – Connect three soundings to make a triangular ‘face’. The faces can then be used to represent a surface. 32. 4 30. 8 XYZ Data files (anybody’s) Edited LOG files Matrix (MTX) files 3/9/2021 32. 5 31. 5 The TIN MODEL program in HYPACK® can make models from: – – – 35. 2 33. 7 27. 2 22. 6 2006 HYPACK Training Seminar 16. 5 9

Delaunay Triangles The TIN MODEL program normally makes ‘Delaunay’ triangles. If you draw a circle that contains all three points of any triangle, no other point will be contained in the circle. It’s takes a little longer to generate ‘Delaunay’ TINs, but they are supposed to be the most accurate models. 3/9/2021 2006 HYPACK Training Seminar 10

Entering the Initial Data 1. 1 Select the Input File. 1. Click the “Input File” button and select the name of the XYZ file (or LOG file or MTX file). Hold Shift key to pick multiple files! 2 Specify the Tin Max Side at 30. 2. – This is the maximum distance you will allow for a triangle leg. 3. 3 Hit the ‘OK’ button. Away we go! 3/9/2021 2006 HYPACK Training Seminar 12

Our 1 st TIN Notice there is a strip and several ‘holes’ where the TIN MODEL did not connect across. – This happens when the distance across these gaps is greater than our MAX TIN SIDE. – Let’s try again, but increase the MAX TIN SIDE to 50. 3/9/2021 2006 HYPACK Training Seminar 13

Keys to Making Better-Looking Models Use the tool icon to view parameters. Change the Z-Axis Ratio to a higher number. This exaggerates the z-axis, making small changes more prominent. 3/9/2021 2006 HYPACK Training Seminar 19

Better Looking Models (Con’t) MODIFY-COLOR to access color dialog. ‘Medium’ and ‘Dark’ spectrum options – More contrast – Less ‘washing out’ due to bright colors. 3/9/2021 2006 HYPACK Training Seminar 20
