Nevertheless, graphics application programming interfaces (APIs), such as Direct3D and OpenGL, were developed to standardize common procedures and oversee the graphics pipeline of a given hardware accelerator. Due to the dependence on specific software, hardware configurations, and desired display attributes, a universally applicable graphics pipeline does not exist. Once a 3D model is generated, the graphics pipeline converts the model into a visually perceivable format on the computer display. The computer graphics pipeline, also known as the rendering pipeline or graphics pipeline, is a framework within computer graphics that outlines the necessary procedures for transforming a three-dimensional (3D) scene into a two-dimensional (2D) representation on a screen.

Remember x comes before y in the alphabet and so we write the x -coordinate before the y -coordinate.This article needs additional citations for verification. Notice that the first number in the coordinate matches the value on the horizontal axis, and the second number in the coordinate matches the value on the vertical axis. If the coordinate has been given a label, such as point A, the coordinate is labelled with an A, or an A followed by the coordinate.īelow is the location of four coordinates on a set of axes, A(4,2), \ B(-4,4), \ C(-5,-3), and D(1,-2). We then express this as an ordered pair of coordinates (x,y).Ī coordinate is marked using a cross where the centre of the x is the required point. To determine the location of a coordinate on the cartesian plane, we need to know its horizontal and vertical location. Here are a few examples of different axes with varying scales, The scale must increase in equal steps, but the scale does not have to be the same for each axis. This is informally known as an L -shaped set of axes as the lines for each axis create a capital L.įor any set of axes, a scale must be accurately drawn on each axis. Sometimes we only use the first quadrant. The values of x and y are different in each quadrant.īelow is a description of the polarity of x and y within each quadrant. The y -axis is drawn as a vertical line with an arrow at both ends and is labelled with a y at the top of the grid. The x -axis is drawn as a horizontal line with an arrow at both ends and is labelled with an x to the right of the grid. the y -axis (the vertical axis) is positive above the origin, and negative below the origin.the x -axis (the horizontal axis) is positive to the right of the origin, and negative to the left of the origin.The \bf -axis meet at the origin, (0,0) where, The general form of a coordinate is (x,y) where the value for x represents the horizontal position of the coordinate, and the value for y represents the vertical position of the coordinate.įor example, the coordinate (3,5) has a horizontal position of 3, and a vertical position of 5. Coordinates are locations of points on a grid known as the cartesian plane.Ī coordinate is written as two numbers, separated by a comma, and surrounded by a pair of round brackets.
