QUESTION
I want to render a cube similar to .
My problem is how to render the face projections.
I tried using Reflector, but it is tricky to size and position so it captures just the face that I want, and also shows the sides.
I also saw I can use a separate canvas to render (I imagine using an orthographic camera), but I wish for everything to be in the same canvas. I saw an example with multiple views, but it seems that they can't be positioned behind.
So, is there a way to achieve this?
...ANSWER
Answered 2021-Jun-14 at 11:27One possible approach to solve the issue:
Setup an orthographic camera such that its frustum encloses the cube. You can then position the camera in front of each side of the cube, use lookAt( cube.position )
to orient it properly and then render the scene into a render target. You need one render target per side. You can then use it as a texture for the respective plane mesh.
There is an official live example that demonstrates how RTT (render-to-texture) is done with three.js
. Try to use it as a code template for your own app.
QUESTION
I have this 3d rotating text css animation working on chrome desktop, but it won't work on mobile. I tried adding webkit prefixes but nothing will get it to work on iphone. Any obvious reasons why?
...ANSWER
Answered 2021-Jun-14 at 00:51I was able to reproduce your bug in both Mobile Safari on iOS and desktop Safari on my Mac, so the bug appears to have at least been related to Safari in general, not necessarily mobile-specific. Safari apparently does not like rotate3d transform animations with only 2 keyframes.
The fix boils down to adding an intermediate keyframe to the @keyframes
CSS (see 50%

QUESTION
is there a way to bind 2 OLAP Cubes with the same structure into one? As for now I have big Datasets for past 10 years (20-50 milion records each cube) that is every day processed. For optimalization purposes I want to separate it. For exaple the data for past 8 years will be processed once and the new data will process daily. For it it would need 2 Cubes but can I merge results from it?
Edit. Im reading on blogs and forums about partitioning the data but how does it really work? Would I be able to process only the new data so I dont need to process all 30+ mil rows?
...ANSWER
Answered 2021-Jun-11 at 16:08Processing these partitions is done separately from the cube design. One way to deal with this is by scripting out the commands and running them in a sql agent job:
1- Connect to the ssas instance, browse to the dimensions folder and hit F7 to open the object explorer details window.
2- Highlight all the dimensions, right click and select process
3- In the dialogue, select the script button and choose script action to new query window or script action to clipboard and save it someplace. This will be the xmla command to update all the dimensions.
4- Next, navigate to the measure group in which you made the partitions and select the last partition in the group which you want to refresh daily. Right click, select process and use the script option to create an xmla command
5- Next, select the measure group folder and select all the measure groups in the object explorer detail window, except for the partitioned group. Right click, select process and script out the command as in step 3.
6- Now that you have all the commands, add them to a SQL Agent job with 3 xmla command steps, one to process the dimensions and the next two to process the measure groups and most recent partition. Note that if this is running under the sql agent service account, that account will need to have permissions to process the cube.
tip add another job to run on the weekends which does a process full over the whole cube. This is a little cleanup step to make sure everything stays in sync.
QUESTION
I am new to MDX and want to develop SSAS cube and need some help on following scenario :
In the SSAS designer, on the Calculations tab:
I am creating one calculated member called [QualityKPI] for which I am writing MDX expression as below :
...ANSWER
Answered 2021-Jun-10 at 19:08In MDX, WHERE conditions are normally done on attributes, not on measures. So, the best approach would be to make an attribute from your Row Count column (i. e. making it part of a dimension).
Then, you could either leave your calculation as it is, enabling users to do their own where conditions, i. e. by dragging Row Count either into a filter or to rows o columns to see the breakdown by row count.
If you want to filter in your calculation itself, then to add the row count filter to the calculation, you would use tuples wherever you use just a measure currently, e. g. (assuming the attribute is called [Dim1].[Row Count]
in the cube, and hence the member for row count 1 would be [Dim1].[Row Count].&[1]
), you would use
QUESTION
I'm trying to include the following pstricks code snippet in R/exams .Rmd exercises, but I have no idea how to do it:
...ANSWER
Answered 2021-Jun-10 at 18:30Yes, it is possible, although I wouldn't recommend it. You can use the following:
- Set up a string with the LaTeX code include pstricks.
- Call
tex2image(..., packages = c("auto-pst-pdf", ...))
so that the LaTeX package {auto-pst-pdf} is used. This supports embedding pstricks in documents for the pdfLaTeX by calling LaTeX for the figure in the background. - Make sure
tex2image()
calls pdfLaTeX with the-shell-escape
option so that pdfLaTeX is allowed to call LaTeX. This is relatively easy by using the R packagetinytex
.
A worked example for this strategy is included below, it is called dist4.Rmd
. If you copy the R/Markdown code to a file you can run:
QUESTION
This is my first post here and I am not that experienced, so please excuse my ignorance.
I am building a Monte Carlo simulation in C++ for my PhD and I need help in optimizing its computational time and performance. I have a 3d cube repeated in each coordinate as a simulation volume and inside every cube magnetic particles are generated in clusters. Then, in the central cube a loop of protons are created and move and at each step calculate the total magnetic field from all the particles (among other things) that they feel.
At this moment I define everything inside the main function and because I need the position of the particles for my calculations (I calculate the distance between the particles during their placement and also during the proton movement), I store them in dynamic arrays. I haven't used any class or function,yet. This makes my simulations really slow because I have to use eventually millions of particles and thousands of protons. Even with hundreds it needs days. Also I use a lot of for and while loops and reading/writing to .dat files.
I really need your help. I have spent weeks trying to optimize my code and my project is behind schedule. Do you have any suggestion? I need the arrays to store the position of the particles .Do you think classes or functions would be more efficient? Any advice in general is helpful. Sorry if that was too long but I am desperate...
Ok, I edited my original post and I share my full script. I hope this will give you some insight regarding my simulation. Thank you.
Additionally I add the two input files

I trying to make a pure 3d cube, using my vectors. I thought it was perfect at once, but when rotate it, I can see some lines are not drawn correctly and it is not perfect.
I can't find why it is not perfect. Is some of my vectors wrong?
I'm using p5.js to draw it. I know they have methods of 3d rotation and some 3d primitives. But I don't want to use them. I want to draw my own 3d cube.

QUESTION
Currently trying to create attraction effect on 3D cubes using createVector function. The attraction designed to trigger when mouse pressed but currently it's stating the error:
...ANSWER
Answered 2021-Jun-08 at 11:29- You're using index
a
for argument ofCubes.attraction
which is expecting an object with apos
vector field (a Cubes ?) - You're trying to position your cubes using
this.x
/this.y
, which aren't changed byupdate
. Use thethis.pos
vector instead - You can optimize by checking for mouse pressed only once, and only then calling
attraction
on every cube with mouse coordinates as vector argument - In physics, force drives acceleration, not velocity. I changed that but maybe it was deliberate of you.
- You should change your class name to
Cube
rather thanCubes
QUESTION
I built an SSAS Tabular model cube and created a date table using calendarauto(). I have marked it as a date table and created a relationship with the fact table using the date column, and both columns have a Datetime data type. When I analyze the data using excel, the date filter is not working correctly. For example, when I filter on the year 2021, it gives me row values for the year 2019 also, but if I use the date column from the fact table, I get the correct results. When I analyze the Tabular cube using Power BI, it works right. Could you please suggest what exactly is going wrong with our date table?
When I put the Fact table date column and date table date column on excel it looks like the screenshot below.
...ANSWER
Answered 2021-Jun-08 at 07:42First, I think that is a bad IDEA to use CALENDARAUTO because it searching for all date columns from your model (and if you have a Customer with a born date eg. 1912-02-02, then you create a big table from that date).
CALENDARAUTO ignores calculated tables and calculated columns searching for date columns. Only the imported columns are analyzed to search for date columns.
Internally, CALENDARAUTO calls CALENDAR providing a date range that include all the days in the range of years referenced by data in the model, according to the following rules:
The earliest date in the model which is not in a calculated column or calculated table is taken as the MinDate. The latest date in the model which is not in a calculated column or calculated table is taken as the MaxDate. The date range returned is dates between the beginning of the fiscal year associated with MinDate and the end of the fiscal year associated with MaxDate.
A better idea is to use CALENDAR where you have more control
