1 B-rep StreamsIt is clearly stated to set up a producer process importing a B-rep, externally defined by some standard polygonal format, e.g. either a wave front or java3D obj file, into an input stream for our geometric pipeline. The boundary representation provided by polygons and normal must be coherently oriented. A filtering of the input file to cope with nonplanar polygons and other geometric inaccuracies may be required for generally archived geometric models implemented primarily in computer graphics. The output stream of coherently-oriented triangles, is then transformed into our twin progressive-BSP (Binary Search Partitioning) trees by the algorithmic steps ... Read More

Use the super() function to call the constructor of the parent class and access functions on an object's parent class.ExampleYou can try to run the following code to implement super()Live Demo                    class Department {             constructor() {}             static msg() {                return 'Hello';             }          }          class Employee extends Department {             constructor() {}             static displayMsg() {                return super.msg() + ' World!';             }          }          document.write(Employee.displayMsg());

We can align an element or the content inside it by using CSS which provides various options for alignment of an element and its content horizontally, vertically or in center.Horizontal AlignmentInline-elementsInline elements or inline-block elements such as text, anchor, span, etc. can be aligned horizontally with the help of CSS text-align property.Block-level elementsBlock-level elements such as div, p, etc. can be aligned horizontally with the help of CSS margin property, but width of element should not be 100% relative to the parent as then it wouldn’t need alignment.Block-level elements using float or position schemeElements can be aligned horizontally with the ...

BSP Trees as a Multi-Dimensional Search Structure

Spatial search structures are based on the same ideas that were invented in Computer Science during the 60's and 70's for solving the problem of quickly processing large sets of symbolic data, as opposed to geometric data, for example lists of people's names. It was invented that by first sorting a list of names according to alphabet, and storing the sorted list in an array, one can compute whether some new name is already in the list in log2n operations using a binary search algorithm, rather than n/2 expected operations required with the help of a sequential search. This is ... Read More

BSP Trees in Data Structure

In computer science, a method known as binary space partitioning (BSP) is implemented for recursively subdividing a space into two convex sets by implementing hyperplanes as partitions. This process of subdividing provides rise to a representation of objects within the region in the form of a tree data structure known as a BSP tree.Binary space partitioning was invented in the context of 3D computer graphics in 1969, where the structure of a BSP tree permits for spatial information about the objects in a scene that is useful in rendering, such as objects being ordered from front-to-back with respect to a ...

Compressed Quadtrees and Octrees in Data Structure

Compressed QuadtreesAt the time of storing every node corresponding to a subdivided cell, we may end up storing a lot of empty nodes. Cutting down on the size of such sparse trees is possible by only storing subtrees whose leaves have interesting data (i.e. "important subtrees"). Again we can actually cut down on the size even further. When we only consider important subtrees, the pruning process may avoid long paths in the tree where the intermediate nodes have degree two (a link to one parent and one child). It turns out that we only require to store the node U ... Read More
