Holography a visual art

Hologram is a technology of creating a three-dimensional image formed by the interference of light beams from a laser or other coherent light source. An interference pattern of photographs which are properly illuminated can create a 3 dimensional effect. This can lead up to the extent of creating 3 dimensional dynamic images which can be observed by bear eyes without the assistant of glasses or any other visual aids.

A simple simulation of creating a static 3 dimensional hologram can be done with our smartphones, all we need is

1.       A transparent Pyramid which is made of glass or plastic. 

2.       Four images placed in the vertices of a square which are properly illuminated by phone's screen brightness.

3.       Ambient light or low light area to view the hologram without noise.

Then you can see the magic.


Hologram is a game changer, for an example if we consider the education sector where students can’t gain practical knowledge, there hologram can provide perfect simulations of real world objects, which are hard to explain without a visual aid such as internal organs of a human body. 

 Also in advertising sector people can use hologram to view products and can do a virtual fit on for dresses or jewels. This can completely wipe out menu cards in hotels as people can get their mouth watery by just seeing the dishes in 3D.

Main advantages of hologram.

1.       To present things innovatively
2.       To create more emotions and an immersive experience.
3.       In order to explain complex content. 

3D dynamic hologram effects can be created using videos, this is much similar to what I have explained above, in order to see how it works check the link below.

You can notice that a properly aligned parallel video of four which complement each other can do wonders and create a dynamic hologram which is pleasing and magical, this can be made even lively by having appropriate music and may be more artistic by having bass and vibration effects, a whole new immersive experience can be invoked this way.

Raspberry Pi can be used to program a dynamic hologram, this is more fast and durable comparing to Arduino, since Arduino is used to accomplish small tasks with crisp. This can be useful to feed real time input using camera and sensors, in order to dynamically gain data and produce a hologram.

For an example if a customer wants to see a virtual fit on of a jewel, there the jewel details are already available in the hologram program, but the customer appearance details has to be dynamically loaded and merged with the jewel details in order to produce such hologram.

Choosing color scheme for Power BI reports

Choosing beautiful colors for an attention seeking Power BI report is always challenging. Sometimes we may have an important message but it might go unseen if proper color scheme is not used, so it is important to create reports which are informational and visually appealing. In this blog our main objective is to get an idea about selecting appropriate color scheme and tools that can be beneficial to do this. What is a color scheme? As you all know not all colors look great together and you can tell stories by just having only two colors, have a look at the following image, there in the middle you can see a circle with same color and same dimension, only thing that changes is the back ground, but depending on the back ground the way you see those circles are totally different. Some small circles appear softer, some appear sharper, and some are brighter also you might notice movements or depth effect too. It is important to choose colors wisely to serve the purp

Ragged hierarchy in Power BI

Case- I have a data set which has to be visualized in a ragged hierarchy. What is ragged hierarchy A ragged hierarchy is a user defined hierarchy with an uneven number of levels.   You can see the above table which has 5 levels of hierarchy. In the first level we only have “World” as a category then moving forward to the next level we have two categories  namely “UK” and “USA” likewise the level of hierarchy is drilling down up to five levels with an uneven amount of categories. Creating a hierarchy in Power BI In the above image  you can notice that I have right clicked the “level 1” column which has to be the first level of our hierarchy, Once it is right clicked there you will notice “New hierarchy” as the second option then you will have to click that in order to create a new one. As you can notice in the above image once I have created a new hierarchy then a new column is created named “Level 1 Hierarchy” in that I have dragged and dro

Five tips to enhance a tableau model with usability features.

In the previous blogs I was more focused in Power BI since i work with it day to day, but this time we are going to dig into increasing the usability features of tableau. This blog revolves around the end-user simplicity, if a model is hard to comprehend then it will be a disaster, so we should deploy some means to stay simple. So without further ado lets head on to the first topic of the day. Configuring table and  column  properties. A model can consist of many tables but the important fact is they have to be unique and it is better if we can have a table description to elaborate on whats it about. This can be also considered as an internal documentation, when a project member is changed it is easy to pick up and continue. We use connections to load data for the tables and we have a connection name for it but once if we set the source it cannot be changed in the latter part, so be mindful because once you are dropping a connection you are losing all the tables assoc
