I am learning Unreal and currently building tree models. I am wanting to change the colour of the leaves between 3 texture samples based on random numbers, and while I have created a blueprint that can compare between numbers and output the correct colour, I can't find an input node that will assign a random number to each of the leaves.
The tree model is all one mesh however the vertices for the leaves are not connected between leaves. If I go into Unreals Modelling Mode and choose the TriSel (Triangle Select) tool I can select each leaf separately with one click, though I cant figure out any way to use this in the material editor.
I have attached a screenshot of the node group to select the base colour image below (the output of this group goes to the "Base Color" input). Currently the "Temp" value is changed manually (which changes the colour of all the leaves with this material), however that is where I want to input the random value for each leaf, if I can.
Thanks,
Dan

So, it's my first time trying to make my own data visualization, and what I want to do is something like a heat map or highlighted table like the original Kohonen (but using squares rather than hexagons) research about countries, but I don't know how to apply it to the map I've got from training the network.
I've read a few links about making a highlighted table and heat map on Tableau, but what I get is always just a table mainly because I'm not using a measure (i just want every country of one color), so, my question is: is it possible to use Tableau for this situation and if so, how could I do it? Thanks!
Original SOM visualization from Dr. Kohonen
Table from Tableau
Yes it is possible to make visualizations like you describe in Tableau - but the question you posed is a bit vaguely specified to give you much more detailed guidance than first take some Tableau training.
For instance, how do you want to determine which row and column to place a country? You may need to write a table calc for row and col positions, which means learning about table calcs. Or you can assign them in a data column.
For square country marks, you'll want a discrete field on the rows shelf, a discrete field on the columns shelf, possible a dimension like Country name on the details shelf. Choose a square mark type, and (important) choose a square cell size from the format menu. Then adjust the size of your squares from the size button and the format menu, and colors and borders from the color button and format pane.
Lots to play with.
I am trying to create multi-line subplots such that each subplot represents a rating factor on which firms are rated, and each line represents a firm's change in rating over time. Note that I don't have the date field. I have a string field that says which quarter of the year the Mean of ratings belong to.
I'm new to tableau and I created something like this:
I want to create multiple subplots: one subplot for each of the 8 rating features in the above diagram, and the subplot has multiple lines representing the variation over time for each company. I have 10 companies.
Please guide me on how to achieve this?
A rough sketch of how I Imagine the plot to look like is below:
This will teach you how to make a panel chart in Tableau: https://tarsolutions.co.uk/blog/build-a-dynamic-panel-chart-in-tableau/
It shouldn't to too complex for what you're attempting (fingers crossed!).
Building the panel chart is a little tricky in Tableau. Not terribly hard once you understand table calcs. I suggest starting simpler by moving Measure Names from the Rows shelf to the Pages shelf, then creating the line charts you want - 1 per page. Then learn about table calc partitions and addressing, including “At the Level” to have the info needed to define the panels
To make a colored line chart,
You need one field on columns that you set to display as continuous, making it green. If it is a date field, right click on the field and choose from the second set of groups, like month or quarter.
You need a continuous field on the Rows shelf, use Measure Values in your case
Use a discrete field on color to determine the number of lines, say Shortname
Set the Mark Type to either Automatic or line
How can I find a sequence of elements that, if inserted into a red/black tree, would be balanced purely by changing colors rather than performing rotations?
You would need to ensure that the new node is always filling out the bottom-most unfilled layer of the RB tree. For example if you had a tree with two nodes it would always be the unbalanced side, like wise if your tree was of four nodes it would be one of the three remaining slots on the third 'row'.
Being able to do this with arbitrary data would pretty much require that arbitrary data to already be sorted (whether in an array or otherwise). Of course, if you're creating an RB tree from already sorted data you shouldn't even need color changes, all the upper-level nodes can be black while any nodes in an unfilled layer (of which there can only be one) will be red if there are missing nodes, or can be all red or all black if there are no missing nodes. If your data is not sorted you will eventually run into a situation where the next available nodes don't fit the available slots.
i want to create a Word Search game using Visual Basic? I've already started it by creating grids (10x10). However, I do not know how to properly insert the words that the user will search for.
Here's a look at what I did as well as the codes.10x10 grid
as you can I see, I created the grid using the Paint Event handler.
I have a text file containing all the words that the user will search. Using VB I open and read all the lines and put the words in an array (not seen in the picture).
I want the words to be inserted in the grid randomly. But I do not know how to?
Any help is much appreciated. Thank you!
The visual grid is a bit of a distraction at this stage. concentrate on getting a list of strings into an nxn two-dimensional string array. I would write a sub which, given a list of words and a dimension, returns a filled-in array (if possible).
A natural choice is a backtracking algorithm, which seeks to randomly place words into a partially filled array. For each new word, generate the collection of all valid locations and then randomly pick one of those locations. If there are no valid locations -- backtrack, removing the most recently placed word and placing it somewhere else. It might help to first sort the list of words to be placed in order of decreasing length, since it will be easier to place smaller words into a partially-filled in array than larger words. Placing the larger words when there are less constraints will thus lessen the amount of back-tracking needed.
When all of the words have been placed, fill in the rest of the array randomly.
I just got a vegetation raster. Its pixels have several fields (i.e. basal area oaks, density of oaks, volume of oaks, pixel value, etc). How do I extract only selected field values to a set of XY points?
The primary tool that you'll be working with is Raster to Point (Conversion toolbox). It includes a parameter to pick which field to pull data from:
The Field parameter allows you to choose which attribute field of the input raster dataset will become an attribute in the output feature class. If a field is not specified, the cell values of the input raster (the VALUE field) will become a column with the heading Grid_code in the attribute table of the output feature class.
If you want to exclude certain values or subset the data, that can be done either before converting (using Con or similar) or after (select by attribute and export or delete). Doing it afterwards gives you a bit more flexibility, but leads to larger point datasets.
