Graphics are used to represent and manipulate image data through displays and processing of physical world image data. Common applications include user interfaces, maps, medical imaging, and more. 2D graphics include pixel art, sprites, and vector graphics. Sprite graphics involve independent objects composed together on a screen. Vector graphics use shapes and colors rather than pixels. 3D graphics provide three-dimensional models and rendering to generate 2D images from 3D data involving geometry, viewpoints, textures, lighting, and shading. OpenGL is a widely used cross-platform 2D and 3D graphics API that interacts with GPUs for hardware-accelerated rendering.

06 clipping
The document discusses several algorithms for clipping lines and polygons in computer graphics:
1. The Cohen-Sutherland and Cyrus-Back algorithms are described for clipping lines, with Cohen-Sutherland using outcodes to determine if lines can be trivially accepted or rejected from the clipping region.
2. The Cyrus-Back algorithm uses the concepts of potentially entering and leaving to iteratively calculate intersection points and clip line segments.
3. The Sutherland-Hodgeman algorithm is described for polygon clipping, using iterative clipping of vertices against clipping boundaries.
4. Both Cohen-Sutherland and Cyrus-Back extend readily to 3D clipping through additional bits for the
Windows to viewport transformation
The document discusses the window-to-viewport transformation process which maps a 2D scene to device coordinates. It involves developing formulas to proportionally map points from the world window to the viewport. The scale and translation factors that relate the world window and viewport coordinates are defined. Changing the viewport position, using multiple viewports, or adjusting the viewport dimensions allows manipulating the displayed scene. Distortion may occur if the aspect ratios of the world window and viewport differ.
Cohen-sutherland & liang-basky line clipping algorithm
The document describes two line clipping algorithms: Cohen-Sutherland and Liang-Barsky. Cohen-Sutherland assigns region codes to line endpoints and checks for complete visibility, invisibility, or partial visibility. It then finds intersection points if the line is partially visible. Liang-Barsky uses the parametric line equation and clipping window inequalities to determine intersection points u1 and u2, clipping the line between those points if u1 < u2. Liang-Barsky is generally more efficient as it requires only one division to update u1 and u2, while Cohen-Sutherland may repeatedly calculate unnecessary intersections.
3 d viewing
The document discusses the 3D viewing pipeline which transforms 3D world coordinates to 2D viewport coordinates through a series of steps. It then describes parallel and perspective projections. Parallel projection preserves object scale and shape while perspective projection does not due to foreshortening effects. Perspective projection involves projecting 3D points along projection rays to a view plane based on a center of projection. Other topics covered include vanishing points, different types of perspective projections, and how viewing parameters affect the view volume and object positioning in the view plane coordinates.
Two dimensional viewing
Here are the steps to solve this question:
(a) Given:
Window: wxmin = 2, wymin = 2
wxmax = 3, wymax = 4
Viewport: vxmin = 0, vymin = 0
vxmax = 1, vymax = 1
Sx = 1 - 0 = 1/1 = 1
3 - 2 = 1
Sy = 1 - 0 = 1/2 = 1/2
4 - 2 = 2
N = 1 0 0
0 1 0
0 0 1
(b) Given:
Window: wxmin = 2, wymin = 2
wxmax = 3, wymax = 4
Viewport
Polygon clipping
The document discusses different algorithms for polygon clipping, which is a process that identifies the visible portions of a polygon through a clipping window. It describes the Sutherland-Hodgeman algorithm, which clips polygons by extending the edges of a convex clip polygon and selecting only visible vertices. The Weiler-Atherton algorithm modifies this approach to correctly display concave polygons. Polygon clipping is important for video games to maximize frame rate by avoiding rendering calculations for invisible portions of polygons.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
