Click Edit > Select Faces in a Rectangular Region Rotate the model so that the section in question is horizontal. The screenshot below gives a good impression of what to look for.ġ. Typically this will be near and on the edges of the mesh.

Manual Cleaning For manual cleaning, we need to cut any section of the mesh that appears questionable. If the browser hangs up or crashes, we’ll have to perform additional cleaning steps After you complete these steps, export the mesh and try to load it in the browser.

These steps are the preliminary cleaning methods before export. Filters > Cleaning and Repairing > Remove Duplicated Vertices Filters > Cleaning and Repairing > Remove Duplicated Faceģ. Filters > Cleaning and Repairing > Close Merged VerticesĢ. The solution is to perform a number of steps that will clean the geometry enough for the web viewer script to be satisfied. If there are too many holes or rough edges, the script could cause the browser to crash or hang up indefinitely. Cleaning the Mesh The web viewer can be temperamental about mesh geometry. You can also find the icon in the main toolbar.Ĥ.If the texture still appears to be shown on the model after toggling the textures off, you know that the Texture to Vertex color was successful. Then press Apply.ģ.Toggle the textures off to check if the conversion was successful. To convert textures to vertex color, in MeshLab go to Filter > Texture to Vertex Color (between 2 meshes)Ģ.Make sure the Source Mesh and Target Mesh are the same. Texture to Vertex Color ġ.The current JavaScript doesn’t support textures, but uses vertex color instead. Once you have imported the mode into MeshLab, we will perform a number of steps to prepare the model for web delivery.

OpenCTM and Meshlab The easiest way to convert a model to OpenCTM is to use the open source 3D modelling program MeshLab. The model won’t load if the web page is opened from the hard drive. The script loads the model through an XMLHttpRequest, which requires the web page be loaded from an http server. You will need a functional web server to place the files in. Demo files The web viewing script is here as a zip file.
Convert mesh to geometry meshlab how to#
Although there are still many kinks to iron out, the following tutorial explains how to create an OpenCTM from a 3D model and place it on the web using WebGL and JavaScript. This makes OpenCTM ideal for web delivery. Using OpenCTM, a 90 megabyte model compresses to 9 megabytes. What is OpenCTM? OpenCTM is a new open source file format for 3D objects that boasts impressive compression capabilities.
