How to Learn a New Programming Language or Framework

  Advances in computing power combined with interactive modeling software, which lets users create images as queries for searches have made 3Dsearch technology possible. The methodology used involves the following steps " Query formulation " Search process " Search result   QUERY FORMULATION True 3D search systems offer two principal ways to formulate a query: Users can select objects from a catalog of images based on product groupings, such as gears or sofas; or they can utilize a drawing program to create a picture of the object they are looking for. or example, Princeton's 3D search engine uses an application to let users draw a 2D or b of the object they want to find. The above picture shows the query interface of a 3D search system.   SEARCH PROCESS The 3D-search system uses algorithms to convert the selected or drawn image-based query into a a mathematical model that describes the features of the object being sought. This converts drawings and o...

 Surface Computing Technology Technology has been taking new turns into the future and so has the mode of interaction become very specific. Human-Computer interaction has brought forward more obstacles and it has become a necessity to satisfy the user’s expectation. Therefore, this paper provides a comparative study of Flat surface computing interface and nonflat surface computing interfaces which mainly focuses on various ideologies that are taken into account. It reflects on certain aspects such as visibility techniques in both flat and nonflat surfaces, the all round view. Computers allow us to have multiple applications done in multiple windows. Use only one keyboard and one mouse and only one person can do work at a time. If we want to watch photos on our computer along with three or four other people, just imagine everyone trying to see them. Microsoft introduces surface computing, Microsoft Surface allows people to sit across in different positions and watch the images. Spre...
