HDAs for processing photogrammetry scans in Houdini.
Copy the HDAs into your Houdini install's 'otls' directory.
For scans taken in two halves (each half an incomplete scan that you hope to combine to make a whole scan), this SOP node helps align those halves. It provides an interface to manually match features between the scan halves by adding matching points to each.
How to use:
- Link the geo for each scan half into the two inputs, ideally with textures applied to make it easier to match features. The first input will be aligned to the second input.
- With Mode set to "Align" (the default) both halves will be visible
- Activate the node's interactive mode (press Enter in the viewport while the node is selected)
- Control-click on either half to add a pair of points to match between halves
- Click-drag to move each point, so that each of the paired points are on the matching parts of each half
- You'll need at least 3 matched points
- Set Mode to "Output" once complete, or "Preview" to see both halves of the scan aligned.
