I actually need a white border around the image so that its visibility is enhanced. Sometimes the algorithm has difficulty in recognizing the marker when not enclosed in a white border.
I cannot get the colors to appear in MeshLab. I specifically need to use the collada file format as eventually the model has to work with Gazebo physics simulator.
I found some info here that suggests it can be a material naming issue but I don’t understand much.
I exported the file into DAE, then I import it back to SketchUp. The colors are visible, so maybe MeshLab has a problem, but as far as I know it is no longer in development.
Did you try to see the DAE file directly in Gazebo?
Custom Shapes: The Add button allows you to import custom meshes to from a link in the model. It currently supports COLLADA (.dae), 3D Systems (.stl), Wavefront (.obj) and W3C SVG (.svg) files.
I need a favor, can you convert this collada (ArUco with white borders | 3D Warehouse) into an obj file. I cannot get sketchup8 (on ubuntu 16.04) to export obj file.
Use SimLab OBJ Exporter: Simlab 3D Plugins - OBJ exporter for SketchUp
You have to find viable solutions, because someone else probably will not be able to turn your SKP files into OBJ anytime you need it.
I have successfully installed the SimLab OBJ Exporter. It is however asking for a license. I have requested a trial license. I think it will take a while before I am able to export a obj file.
