Point Cloud Data Code Used To

About the shader You can check the Shader code used to generate triangles. (warning: geometry shader stuff) If you inspect the Generate function in the PointCloudGenerator script, there is a part where it creates mesh with point topology.

While we have in the meantime released a similar feature for point clouds, his approach to using and transforming such data is very interesting and can be applied in many different and new ways.

In addition his script has some nice tricks that we dont, so if youre into point clouds be sure to read this Hi My name is Leon Denise, Im an independent artist programmer.

I draw comics, make games, code shaders, hug trees and talk to cows.

You can find my work on GitHub, Giphy and of course here on Sketchfab In this tutorial, Im going to explain how I did the Simon Splash: I used Agisoft PhotoScan to generate the point cloud and Unity3D to create the mesh.

The Unity3D project can be downloaded at github.comleon196PointCloudExporter.

About the project The project is a point cloud tool used for generative art.

It is a real-time software that generates triangle particles from a point cloud and displace them in a vector field with specific rules for velocity behavior.

The tool also exports the generated particles into a standard 3d mesh and bakes the vertex colors into a map with generated texture coordinates.

When you zoom in, points stay as dots, it creates to me a frustration that needs to be satisfied.

Im sharing the source code of the program, its a simplified version (no GPU particles) of my point cloud engine.

For the sake of comprehension and because the advanced version is part of a commercial project.

Export a point cloud After you have generated a point cloud in your favourite software, export it as PLY format: binary encoding with position, normal and color.

Examples with Agisoft Photoscan and MeshLab: My PLY importer C script is pretty naive and there is chances that it wont work with a PLY exported from a different software.

If you improve the importer script, and like to share, do not hesitate to send a pull request on the git repository.

Point Cloud Data How To Use Git

If you dont know how to use git, find the download zip button: You will find the scripts and shaders used to generate triangle mesh from a point cloud.

If you dont know about Unity3D, the official documentation is great and there are plenty tutorial resources all over the web.

Start the play button, select the PointCloud game object in the hierarchy window, so you can adjust parameters in the inspector window.

Set the load parameters PointCloudGenerator will load a file in the StreamingAssets folder and automatically adds the.ply extension.

Thats why File Name is just Simon2.

You can adjust the Maximum Vertices count to get more details.

Set the renderer parameters Size is the radius of the triangle.

About the sprite The texture used for the sprite must have clamp wrap mode.

Since we use triangles instead of quads for performance, the UV mapping is sized to cover the triangle.

About the shader You can check the Shader code used to generate triangles.

If you inspect the Generate function in the PointCloudGenerator script, there is a part where it creates mesh with point topology.
