  Computer Graphics Computer Graphicsis the creation of pictures with the help of a computer. The end product of the computer graphics is a picture it may be a business graph, drawing, and engineering. In computer graphics, two or three-dimensional pictures can be created that are used for research. It is the use of computers to create and manipulate pictures on a display device.

  Graphics Pipeline (Rendering) A graphicspipeline is a series of steps that a GPU performs to convert 3D models into 2D images for display on a screen.

  a vertex shaderprocesses each vertex's attributes, such as position, color, and texture coordinates. vertex shader's primary role is to transform 3D coordinates into a 2D viewport using transformations like translation, rotation, and scaling. Vertex Shadder

  It involves theconnectivity of vertices to form triangles, which are then passed to subsequent stages for rasterization and shading. Efficient triangle assembly is crucial for accurate and optimized rendering, as it sets the foundation for producing detailed and realistic images in computer graphics. Shape Assembley

  • The rasterizationprocess involves several key steps: • First, the geometric primitives are mapped to the pixel grid of the display, and coverage of each pixel is determined. • Next, the rasterizer generates fragments for each pixel that a primitive covers.The depth test and other per-fragment operations are then performed. Rasterisation

  • The fragmentshader in graphics pipelining calculates the final color, depth, and other attributes of fragments after rasterization. • It handles tasks like texturing, lighting, and special effects, determining how each fragment appears on- screen. Fragment Shadder

  Testing involves operationslike depth testing, which ensures that only the closest pixels are rendered. Blending combines the color of a pixel with the background, enabling effects like transparency by adjusting pixel colors based on their corresponding alpha values. Testing & Blending
