+# HeadsNet
+
+This dataset uses the [thispersondoesnotexist_to_triposr_6748_3D_Heads ](https://huggingface.co/datasets/tfnn/thispersondoesnotexist_to_triposr_6748_3D_Heads) dataset as a foundation.
+
+First normals are added to the ply files for each vertex, the easiest method to achieve this was with a simple [Blender](https://www.blender.org/) script:
+```
+import bpy
+import glob
+import pathlib
+if not isdir(outputDir): mkdir(outputDir)
+importDir = "ply/"
+outputDir = "ply_norm/"
+if not isdir(outputDir): mkdir(outputDir)
+
+for file in glob.glob(importDir + "*.ply"):
+    model_name = pathlib.Path(file).stem
+    if pathlib.Path(outputDir+model_name+'.ply').is_file() == True: continue
+    bpy.ops.wm.ply_import(filepath=file)
+    bpy.ops.wm.ply_export(
+                            filepath=outputDir+model_name+'.ply',
+                            filter_glob='*.ply',
+                            check_existing=False,
+                            ascii_format=False,
+                            export_selected_objects=False,
+                            apply_modifiers=True,
+                            export_triangulated_mesh=True,
+                            export_normals=True,
+                            export_uv=False,
+                            export_colors='SRGB',
+                            global_scale=1.0,
+                            forward_axis='Y',
+                            up_axis='Z'
+                        )
+    bpy.ops.object.select_all(action='SELECT')
+    bpy.ops.object.delete(use_global=False)
+    bpy.ops.outliner.orphans_purge()
+    bpy.ops.outliner.orphans_purge()
+    bpy.ops.outliner.orphans_purge()
+```
+Importing the PLY without normals causes Blender to automatically generate them.
