How to Graph XYZ Data into MESH Inside Microsoft Excel
I'm able to import the data into blender as a point cloud with this python scripthowever I would like to create a model with solid faces. Is there a way when importing the data to somehow join the points to create faces instead of generating thousands of separate points?
Currently, this what I have in terms of point cloud. The end product would look something like this minus the texture and obviously the model wouldn't be as regular as this one. Basically we can import the ponts directy from the cvs file with the Text input node and tranform the coordinates in vertices with the Vector in node. Then what's left is to provide a sequence of indexes based on the specific grid of acquisition.
In this particular case, we are defining the first polygon a quad an then repeating the process for every quadrlet with a combination of list managing and a int range. The last segment of the algorithm is used to get rid of the faces built by the vertices of a row and the first of another. In this particular case is deleting one item of the list every Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

If the X and or Y spacing is non-linear as shown above then normal gridding methods cannot create a matrix. To work with this data in Origin, you can convert it to a Virtual Matrix using an X-Function w2vm or you can rearrange it into an XYZ column format using a menu option.
This opens the w2xyz dialog box. This dialog box uses the w2xyz X-Function. In the Conversion Options branch of this dialog box, you can specify how the original data are arrayed: X across columnsY across columnsor No X and Y meaning the X and Y coordinate values are not supplied and Origin should use column and row indices.
If supplied, the X and Y coordinates do not have to be evenly spaced. For more information, see: Recalculating Analysis Results. For help with range controls, see: Specifying Your Input Data.
Choose the label row to supply the X or Y coordinates. Specify three columns for the output XYZ range. X, Y and Z data can be output to different sheets and books.

Is there an existing software that takes XYZ data relatively low resolution and creates a decent mesh for exporting as a. STL file? I have tried MeshLab, but with no success.
If that is the correct program I could use some help understanding how to utilize it to meet my needs. If you are dealing with spatial data, CloudCompare another free program seems to be much more versatile. It can import point clouds from a variety of formats.
If you want to manipulate the mesh afterwards, CloudCompare allows you to easily crop it or split it, which doesn't seem to be possible in Meshlab. This is under:. The disadvantage of CloudCompare is that it doesn't provide you as much choice of different fancy algorithms for creating the surface mesh.
It is basically just connecting the dots.
The resolution will be the resolution of your point cloud, so if your point cloud isn't very dense, it may look a little angular. Meshlab has different options for creating the mesh surface, which can make things look smoother.
To access these options, you first need to calculate the normals for your point cloud. After loading the point cloud, select:. You then have a couple different options to create the mesh. The two options that I have found that can create terrain models are:.
Both of these options set the resolution of the mesh independent of the resolution of the point cloud that you are starting with, so you have to play with the settings to get the desired resolution. For the Marching Cubes algorithm, you set the resolution with the "Grid resolution" option. For the Poisson algorithm, I think that you increase the resolution by setting "Reconstruction depth" to a higher number, but the relationship isn't obvious to me.I have the following problem: I need additional elevation points in xyz format for extending cross sections.
I've loaded a digital terrain model into SMS and created a mesh. I also created a coverage line with vertexes on a specific part of the mesh from which i want to extract the point coordinates and elevation information. I've tried to create a scatter set from the coverage and export the information in ascii format, but the data wasn't exported in xyz format. Does anyone have an idea how to export xyz data from a created line or points? As I understand it, you want to extract a cross section from a scatter set.
The changes will be available in the next update of SMS Follow these steps:. You will need to modify the file some to remove the extra lines. You can post now and register later. If you have an account, sign in now to post with your account.

Sign In Sign Up.The resulting 3D-plots can be interactively rotated and viewed from arbitrary perspectives in real-time. Images can be snapped for printing, or for including in reports, by pressing the "p" for "picture" at any time within WF3D.
XYZWF supports a variety of options described further below. Use uniform surface color. Matrix columns, graph left-right -ylabel "xx" - Set Y-axis label.
Matrix rows, graph depth-axis -zlabel "xx" - Set Z-axis label. Matrix values, graph up-down -zrange z Z - Force min and max Z-range. RGB values in range 0. Do not automatically invoke viewer. Therefore, only Z-values are necessary in the data file input. One value on a line. Rows of the X-Y grid or matrix values should be separated by a line containing the keyword, 'next'.
All rows should have the same number of values. This way, you do not need to specify the row or column dimensions of your data. XYZWF determines this for you automatically.

Python: How to Make a Mesh from XYZ Coordinates
On the initial display, the X-axis is drawn as the horizontal left-to-right axis. The Y-axis is drawn as the depth-axis into the screen. And the Z-axis is the vertical top-bottom axis on the screen.
By default, the X-and-Y axes take integer values corresponding to their row-column indices, from 0 to the number of points on the respective axis minus one.
These can be renumbered by the -xrange and -yrange options. Below is an example of a Num-Utils Real-Matrix formatted data:! Real Matrix[2,2]! M[1,1] 1 2 M[1,2] 2 1 Version 7 has many new features that make creating true 3D graphs like Surface Charts, Wireframes and 3D lines from XYZ data inside Excel much easier and faster than ever before!
XYZ Mesh was originally created to graph geological land formations when gathering data for drilling rigs. Over the years XYZ Mesh has been adapted into land surveys, atmospheric data graphing, oceanic depth mapping, metrology, sound frequency dissipation and several more fields of study.
XYZ Mesh has proven useful due to the ease of use and the flexibility of sharing data. This ensures that your customers, clients and even coworkers can see your progress without needing any additional software, just Excel! Version 7 actually adds to this function, allowing companies to save their project files into an encrypted format that only their company license can read.
This option ensures that only your company can open, read and export the files contained within your project folder. Have sensitive LiDAR data or land surveys that you do not want leaked? Simply save the file as a Secure Project and only your company issued product can open it. Microsoft Excel exported documents can have customized information about the data, client and even your business.
XYZ Mesh version 7 brings more to the table than any other version released to date. Some of these improvements include:. What can XYZ Mesh do for you? Check out these features:. XYZ Mesh comes with the capability of exporting all of your converted data directly into Excel. Wireline Contours can also have custom background images, used for image overlay.
Version 6 brought along the Floating Graph window. Microsoft Excel has a limit of data points that it can plot at one time. This includes rows and columns. XYZ Mesh does not have this limitation. To compensate for this, XYZ Mesh now comes with the ability to produce those values before it is exported into Excel. Now you can preview, convert, export and curve all your data within XYZ Mesh.
Version 6 comes with a distance calculator. With the distance calculator you can calculate the distance in X, Y, Z and point-to-point distance of two data points within a few clicks. The data will be updated under the graph. XYZ Mesh version 7 has been updated to be compatible with the latest version of Microsoft Office, We have also taken steps to ensure that it is also backwards compatible with previous version.
Now data converts almost ten times faster than version 6, making this the largest increase in speed XYZ Mesh has ever seen! The current user manual has been included in every release of XYZ Mesh v7.
