GRAPHICS PIPELINING and GRAPHICS RENDERING


Today’s every computer has a powerful 3D graphics pipeline. Graphics Pipeline is a special software or hardware system that efficiently draws 3D primitives in perspective. Usually these systems are optimized processing, 3D triangles with shared verticles. The basic operation in the pipeline map the 3D vertex locations to 2D screen positions and shade the triangles that both look realistic and appear in proper. Therefore, the graphics pipeline contains much more machinery tools for efficiently processing and composing.

Structure of Graphics Pipeline 
  • Frame Buffer : display.
  • Geometry processing : Transformation and lighting
  • Rasterization : Hidden Surface and simple shading.
  • Texturing : Perspective correct texture lookup.
  • Antalising : Multisampling
  • Shading: Multiple textures and textures, combines.

Computer Graphics Rendering  Computer Graphics Pipeline is the process to generate two-dimensional images from given virtual cameras and 3D objects. The pipeline stages implement various core graphics rendering algorithms. From the computer graphics pipeline, we will achieve these ideas

  • Understand the various graphics algorithms
  • Program low-level graphics program
  • Necessary for programming GPU
  • Help to analyze the performance.

The graphics rendering pipeline is the process of creating a 2D image from of a 3D model (scene) is called “rendering”. All of these steps are Graphics Rendering Pipeline. All animation or motion in 3D, in 2D has fractional value. All graphical function happen at the scan conversion algorithm. In scan conversion, stage all algorithms will run and work with different objects, mining all color, reflect color. Scan-line algorithm have a variety of applications in computer graphics system and it’s related fields.

Computer Animation


Computer Animation is the use of computers to create animations.

There are few different ways to make computer animations. One is 3D animation. One way is to create computer animations is to create objects and then render them. This method produces perfect and three-dimensional looking animations. Another way is to create computer animation is to use standard computer painting tools and to paint single frame and composite them. Later, these can be either saved as a movie file or output videos. One last method of making computer animations is to use transitions and other special effects like morphing to modify existing images and video.


DiGITAL Camera Function|


Many people have no idea – ” how is working the Digital Camera but using the Digital Camera. Here, lets I described about the function of Digital Camera.

A digital camera is an example of 2D array input devices. In a camera, the image sensor is a semiconductor device with a grid of light sensitive pixels. Two common types of arrays as known as CCDs (Charge Coupled Devices) and CMOS (Complimentary MetalOxide Semiconductor) sensors. The digital camera is the raster graphics display system. Digital camera are raster scan that using display pixel. Digital camera’s lens project an image of the scenes to be photographed onto the sensor and each pixel measures the light energy falling on it (sensors). Most color cameras are working by using a color filter array or mosaic to follow each pixels to see only red, green, blue light.  The image software of the color camera to fill in the missing value in a process known as demosaicking.

Digital camera charge the light of pixel, where flow light enough, then the charge will be enough. And when the light flow less, then the charge will less. In the digital camera charge variation depend on the light.Names and Functions of Working Parts

One the camera, use three separated layers in the arrays measure three intent or object red, green, blue values at each pixel produce a usable colors Image except of further processing. A fixed number of pixels in the array determine the resolution of a camera. In digital camera, control signal setup in front of the image.

In a example, the 1920×1080 pixel cannot read all of these bits. A camera with an array of pixel 3000 columns and 4000 rows pixel, which has 6 million pixels called 6-megapixel camera.

The Video camera can create 35 megapixel or 35mpixel, or high resolution. Because they have using image processing.


MPEG STANDARDS |


MPEG STANDARDS

All MPEG standards exist to promote system interoperability among your computer, television and handheld video and audio devices. They are:

  • MPEG-1:  the original standard for encoding and decoding streaming video and audio files.
  • MPEG-2:  the standard for digital television, this compresses files for transmission of high-quality video.
  • MPEG-4:  the standard for compressing high-definition video into smaller-scale files that stream to computers, cell phones and PDAs (personal digital assistants).
  • MPEG-21:  also referred to as the Multimedia Framework. The standard that interprets what digital content to provide to which individual user so that media plays flawlessly under any language, machine or user conditions.

What do You Think About Computer Graphics


What do You Think About Computer Graphics.

Actually, if you got to know Photoshop or operate any graphics software, you never became a Graphics Designer‬, that call Image Processing Person. When you will make image and developing that image by using input data and find a proper output and simulation the image, that’s call Computer Graphics.

Do you know that Computer Graphics‬ always more usage Medical Science and Medical Technology‬, such as X-Ray, Citi Scan, Computed tomographyCT, UltraSonogram, Post Surgical Operation. In the X-ray, such as like as X-ray Computed Tomography (CT) is a technology that uses computer – processed x-rays to produce tomographic images (virtual ‘slices’) of specific areas of the scanned object, allowing the user to see inside without cutting. 

Goals of Computer Graphics:

  • Generate Synthetic images
  • Do it in a particular way and scientifically sound
  • In a real time
  • And make it easy.

When user edit any image in photoshop, or doing work on photoshop tools that is Image Processing Jobs; and which user do this process that is called Image Processor that’s not mean the Graphic Designer. In the image processing, user works with only input image and output image.


Thunderbolt™ 2 | 4K Video Stream Technology


Great News for Video Lovers

Intel brings “Thunderbolt™ 2” technology, the next generation of the technology enables 4K video stream file transfer and display simultaneously – that’s a lot of eye-popping video and data capability. Intel’s Thunderbolt™ 2 Doubles Bandwidth, Enabling 4K Video Transfer & Display 20Gbs bi-directional channel that supports data and display.
Already, Thunderbolt™ 2 is now a standard feature of Apple’s all MAC Pro.

Absolutely, that’s great news for all filmmakers, film lover and rest of Us.
