OBJ format more discrepancies may occur due cyclic overlap or piercing polygons. OBJ format: in case of complex polygons in. The rendering time was taken using performance recording in Tableau.) But there is a disadvantage of. OBJ model (You can compare rendering time on the picture above. OBJ model has less marks in Tableau and looks better aesthetics. Obviously, due to the lower number of marks, Tableau rendering performance is also better with. STL format works with triangles, the 3D model requires more polygons than the same 3D model in. OBJ format created in Tableau (see a picture below).Īs. To further explore some of the advantages of OBJ files, let’s compare the same 3D model in.

OBJ format are available in the internet for free ( for example)

you can open it by Notepad (I use Notepad++ on PC and Atom on Mac) OBJ format (feel free to investigate other types of files if you like.) The reasons I prefer. Many of these work with polygons with more than 3 vertices and contain information about textures and groups of polygons. But, there are different formats of 3D models including. The issue with STL models is that they do not include information about polygons’ colors and they work with only triangles (i.e. You can’t really tell it’s a bar chart, but it is!Įverything above is based on. For example, in the following, I used bars:

We can also experiment with other marks including bars, lines, circles etc. I used the technique in my viz ‘Polygonal Cities’ which you can find here: The only thing new is using Excel to prepare the data instead of Alteryx. NOTE: As noted previously, I haven’t done anything new here - I’ve just followed the method described by Anya’s A’Hearn. For instance, below I’ve colored based on the average of X.Īnd, with this, our 3D model is complete. There are a variety of things you can do here, including coloring by Polygon_id or a calculation based on X,Y or Z. Now, when you change the parameter values, the model will rotate. You can now use these calculated fields in place of X, Y, and Z. The formulas calculate projection onto a plane. I copied and pasted the calculations from Anya’s workbook . įor rotation you will need to create 3 parameters: XY-Angle, XZ-Angle, YZ-Angle and 3 calculations: x_rotated, y_rotated and z_rotated. You can find out more about the algorithm. The painter’s algorithm sorts all the polygons in a scene by their depth and then paints them in this order, farthest to closest. You can notice that the polygons on the pic above were sorting by Y axis in ascending order, so it can explain by painter’s algorithm. Use the X,Y and Z fields for creating a preview, so you can check you model at a glance. STL file in Excel, check ‘space’ as delimeter We only need to keep the rows with a prefix of “vertex”, then numerate the rows. STL format contains data about vertex coordinates (X,Y,Z) for each polygon with 3 vertices. .STL is a text format, so you can use Notepad for opening and editing it (I use Notepad++).

You can find my code here: īut you do not need Alteryx or Python to get data from.

I, like many others, don’t have an Alteryx license so I used a Python script for parsing the files. Anya’s blog contains a link to an Alteryx flow which converts the STL file to a TDE (Tableau Data Extract). Each row in a STL file represents a vertex and the format works with only triangles (polygon with 3 vertices). One such process is described in Anya’s article.

These tools allow you to export your model to ASCII STL (stereolithography) files. There are a number of tools available for creating 3D models, including Blender (free), Meshlab (free), or SketchUp (not free). The Tableau community is so amazing and I have personally be inspired by all these methods, having used them to create some of my own 3D models in Tableau. If you have not seen the above or read these blogs, please take a few minutes to do so.

And Anya A’Hearn worked with Philip Riggs built the STL to TDE/Hyper convertor in Alteryx, as detailed in The 3D Full Monty.īig thanks to Allan Walker, who shared the above history with me. Allan Walker applied “shaders” – Guassian filters, slope, smoothstep functions. Bora Beran simplified his technique in his blog, Going 3D with Tableau.

Noah Salvaterrapioneered these techniques when he created a 3D Tesla. I’m definitely not the first person to build 3D models in Tableau.
