You can get an idea of the size of your object from the bounding box information in this window.Ģ.4 Go to File/Save-As, and save your model as a VRML file with a WRL extension (e.g. In this case a value of 0.015 typed next to the X value would scale the object to the size I wanted. Click on Filters/Normals, Curvature and Orientation/Apply Transform.Ģ.3 - In the Apply Transform window, click the Scale radio-button, then click the Uniform check-box. You may not see the texture in some cases, but that will be fixed later.Ģ.2 - If your units are not in meters, your object must be re-scaled. Here are the details of how to do that.Ģ.1 - Open the already-textured model in MeshLab. The resulting file needs a quick modification in a text editor in order to work. ![]() This is already covered in another Shapeways tutorial, but I'd like to quickly summarize the process and additional detail.Īny model you can get cleanly into MeshLab with it's UV coordinates intact can be converted in a VRML97 file by MeshLab. Part 2: Exporting your models to VRML for color printing. You will import this into MeshLab and export to VRML for uploading to Shapeways. change one dimension to match that of the rectangle you created, and the picture will line up with the frame.ġ.9 - Click on File/Export/3D Model, and export a Collada file of your model. In the Texture section you will see the dimensions listed. The image is applied to the model, but it isn't the right size.ġ.8 - Click the Edit tab of the Materials window. Click the center of the picture frame to fill it with your image.

Make the rectangle about 200mmx150mm or less. ![]() In this example, you will use Sketchup to create a simple 3D picture frame with an image.ġ.1 - In SketchUp, click on rectangle and draw a rectangle with a proportion of 4 x 3 units. This step-by-step tutorial shows how to use Google Sketchup, MeshLab and VRML to add image textures to your 3d models.
