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

How to use GitHub releases as markdown image storage

I often uploaded images to GitHub issues and used their URLs in markdown files (such as README.md).
This method was convenient since it didn’t require adding the images to the repository, and each image had a unique URL.
However, in (probably) March 2025, GitHub changed their policy so that accessing images uploaded to issues now requires cookie-based authentication.
This applies even to images uploaded to issues in public repositories.

As a result, the benefit of 'anyone who knows the URL can access the image' has been lost.

	-- Function to get perlin noise
	local function perlinNoise(x, y, scale, height)
	return math.noise(x * scale, y * scale) * height
	end

	local size = 50 -- Size of the terrain
	local scale = 0.1 -- Scale factor for Perlin noise

	#ProTip™: You can pause win10 to 11 update for much longer,
	if you click: Pause updates, then un-pause it (before that last pause date), then pause again instantly.
	Now you can click 'pause for 7 days' many times.. got myself almost 1 month extra.
