How to notarize a Unity build for macOs 10.15 Catalina

As of January 2020, all apps running on macOs 10.15 Catalina are required to be notarized. For Unity games distributed outside the Mac App Store, such as with Steam, the notarization process is done post build using a series of Xcode command line tools.

Prerequisites

• a Mac that is compatible with macOs 10.15 Catalina :
  • MacBook (2015 or newer)
  • MacBook Air (2012 or newer)
• MacBook Pro (2012 or newer)

Steps to create Textured Mesh from Point Cloud using Meshlab

Get your PointCloud into MeshLab

• Import the pointcloud file in ".ply" file format in Meshlab. Before importing make sure you do some pre-processing / cleaning on point cloud so as to ease the process of meshing.

Point Cloud Simplification and Normals Computation

• Next we need to reduce the number of point samples for smooth meshing.
  • So go to Filters -> Point Set -> Point Cloud Simplification. Enter Number of samples circa 5% of original number of points. Make sure Best Sample Heuristic is checked.
• After point cloud simplification, make sure to select Simplified point cloud in the Show Layer Dialog on the right hand side. If not visible, it can be opened by navigating to View -> Show Layer Dialog. Now we need to compute normals for point set.
• So go to Filters -> Point Set -> Compute normals for point sets . Enter Neighbour num between 10 - 100. Initially try with 10 and

// Doesn't require pow()

// Not smoothed i.e. like a triangle function
float linearParabola(float x) {
    return 1.0 - abs(x * 2.0 - 1.0);
}

// Slightly smoothed, no math function
float parabola(float x) {
    return 4.0 * x * (1.0 - x);
