I need to look through the code to find the unit tests as this is my first importer modification. Anyway, will report back here and will work on it tomorrow. It offers features for processing raw data produced by 3D digitization tools/devices and for preparing models for 3D printing. It provides a set of tools for editing, cleaning, healing, inspecting, rendering, texturing and converting meshes. I will have a look at the importer again, perhaps the file parsing is into an intermediate format. MeshLab the open source system for processing and editing 3D triangular meshes. The reason that I mention that is that if we do a pass to detect presence of Vertex Colors we could use that to decide if we are going to add the Color Vertices, so I won’t want to default to Gray like they did, as we already have a default material. Despite collada import functionality coming mainly from VCGLIB, there is enough meshlab (eg the Meshmodel) in the importer to make development within meshlab to be more appropriate that. More importantly also, they are always generating vertex colors (when import mask option for Vertex Colors is enabled) and that is inefficient for memory as this is non-standard. Meshlab collada importer takes 40 minutes to import g400.dae, compared to 40s by pycollada, suspect horrendously inefficient XML handling is the culprit. Fortunately there's a solution known as polygon reduction. Some tools like ZBrush can quickly create a high polygon count, making it easy to exceed our upload limits. We currently support up to 1 million polygons and/or 64 MB files. You con manually reposition your object or run the ' Set Origin. There's a limit to the complexity of objects that you can upload to Shapeways. Blender is correctly importing the geometry in the scene while keeping the object's original coordinates (Meshlab doesn't). Once you correctly export the file to OBJ format, there should be no issue related to the source. Also, they support an optional alpha after the RGB, which defaults to 1. Import is correct: change origin and shading mode. png file made by snapshot in meshlab and the. obj file, when opened in meshlab, is lower resolution than the original agisoft model - it looks smooshy compared to the the crisp delineation of the agisoft model. MESHLAB, examples which illustrate the use of the meshlab program, an advanced mesh processing system for automatic or user-assisted editing, cleaning, filtering, converting and rendering of large unstructured 3D triangular meshes. We have Color4.FromInts(r,g,b,a)), so I will probably go the other way. The results are better - higher resolution - than exporting a pdf from agisoft, then converting to jpg in photoshop. They have RGB as additional tokens - if R,G & B are < 1 they are scaled by 255, but are otherwise used as is. I got the red bunny with “HI” in MeshLab, so looks good.
