For the second one an indirect solution seems to be reading the camera translation from Windows > Copy Camera Settings to Clipboard. 2- Move the trackball to somewhere in the space, and read the current trackball coordinate. I have been trying to find these two functionalities for convenience: 1- Enter 3D coordinates to relocate trackball to desired point. Would there be a way to do this precisely (setting a precise percentage) in MeshLab? Many thanks in advance for any help. I see that basically what I'm looking for is performed in Blender by scaling everything along the normals. Please let me know if you find something.ĭear all, I'm trying to 'inflate' a mesh. Hi Alex, Did you find any solution for this problem? i am facing the same problem. Is there a way to do this in meshlab or is anyone aware of any preprocessing methods which can help remove the vertices for the internal parts of the object. I need to upsample the vertices of the object but only for the external visible parts of the object are of interest to me. Hello, I have a mesh of an object with some internal parts which are not visible outside.

However, I have no idea how to do this, and. My idea is to photograph the real object together with a ruler and then "resize" the object via MeshLab on the basis of the real size of the ruler.

However, any photogrammetry software I use produces a model with arbitrary coordinates. In other words, the 3D model is required to be the same size as the real-world photographed object. I would like to use a photogrammetry software (e.g., 3DF Zephyr Lite) to get a measurable 3D model of a real-world object. Is there a way to modify a mesh such that this condition is fulfilled? Since long thin triangles seem to be used (for example) along the length of a cylinder, then one way might be to break a cylinder into several cylinders next to each other with the same axis. Specifically if the height to base ratio is greater than 20, the triangle is rejected. However, the model does not like long and thin triangles. I have an application that can use the triangles in an STL file for its model.

The following code produces the scene below with the object in the center of the cameras and the RGB-axis shows the origin of the scene. I have camera positions and rotations from a camera alignment (4x4 transformation matrices). What could be the reason for this, and is there any way to. The result is usually pretty good but I noticed the triangle edges have colors that don't blend well into each other (see attached PNG). From there, I apply a texture Parametrization: Trivial Per-Triangle and then Transfer: Vertex Color to Texture. I import a 1 inch subsampled cloud into MeshLab, compute normals for the point set, and then run Surface Reconstruction with Ball Pivoting. Hi, I use MeshLab to create meshes from point clouds. Besides the flat surfaces, there are sharp edges and a few curved surfaces, see attached screenshot. In the CAD part, these are (unnecessarily) broken up into thousands of triangles. It is a stamped part, which mainly consists of planar faces. It imports nicely into MeshLab and even retains the colorized surfaces of the original CAD model. Hello Community, I have a CAD part in WRL format with a file size of 5 MB, consisting of about 100,000 vertices and about 50,000 faces. In the CAD, these planar faces are (unnecessarily) broken up into thousands of triangles. It's a stamped part, mainly consisting of planar faces.
