The easiest way to publish this to Sketchfab is to use the Unity Exporter. It will create a triangle topology mesh that will replace the point topology mesh. To export the model, you have to press the export button. Save Baked Colours will open a save dialog window, asking where you write the texture file.Export will create a mesh ready to be exported.Displace will start a displacement sequence, with the chosen parameters.Reset will move the vertices to their original positions.Generate is triggered when pressing start button, and can be used to reload point cloud.If you inspect the baked mesh, you will find the generated texture coordinates. That’s why this tool have a baking map colors, so the mesh can be imported on Sketchfab or any 3d viewer. Shader Baked is the shader to use when triangle mesh is generated.Ī baked map with a ‘details’ value of 16:īecause you can’t always have custom shader, you can’t set the triangle color from the vertices color attribute.Circle Radius is the size of the color on the map.Details is a sort of level of details for color.This is where you can adjust and customise the displacement behaviour.
This simple version is about two vectors: a smooth random direction and moving away from a point in space. The displacement behaviour can be found in the “Displace” function.
I’m using geometry shader mainly because you can not setup custom attributes for vertices in Unit圓D. Manipulating vertex in a shader is about parallelism and knowing if a point in space belong to a triangle requires storing data into vertices. The challenge is to display triangles that will face a certain direction. That part shows a function that create a triangle from a point: a geometry shader. Here is a scary screenshot with hieroglyph characters known as shader language code. With the PointCloud shader, you will get this render: triangles with color and direction. If you change the shader for “Unlit/Color” for example, you will get this render: points. Then a geometry shader is generating triangle from point. So the script create a mesh with no triangles, only points. If you inspect the “Generate” function in the PointCloudGenerator script, there is a part where it creates mesh with point topology.
UNITY CLOUD BUILD API CODE
You can check the Shader code used to generate triangles. On the right, sprite with repeat wrap mode. On the left, sprite with clamp wrap mode. Since we use triangles instead of quads for performance, the UV mapping is sized to cover the triangle. Disabling mipmapping will give better results. The texture used for the sprite must have clamp wrap mode.
PointCloudGenerator will load a file in the StreamingAssets folder and automatically adds the. Start the play button, select the PointCloud game object in the hierarchy window, so you can adjust parameters in the inspector window. To use the tool, open the scene “PointCloudExporter”. If you don’t know about Unit圓D, the official documentation is great and there are plenty tutorial resources all over the web. You will find the scripts and shaders used to generate triangle mesh from a point cloud.
UNITY CLOUD BUILD API HOW TO
Start the Unit圓D projectĭownload, install Unit圓D and grab the project here. If you don’t know how to use git, find the download zip button: If you improve the importer script, and like to share, do not hesitate to send a pull request on the git repository. My PLY importer C# script is pretty naive and there is chances that it won’t work with a PLY exported from a different software.
