All the Programs of 5th Sem Computer Graphics Lab with their output in different steps. These programs include basic drawing algorithms, 2D & 3D transformations, clipping techniques, hidden surface removal, shading, projections, and simple graphics-based applications.
The Rajasthan Technical University (RTU) Computer Graphics Lab is designed to provide students with practical experience in graphics programming and visual computing concepts. This lab helps students understand how images, shapes, and scenes are generated, transformed, and displayed using computational techniques. Students learn to implement fundamental graphics algorithms and create interactive graphical applications using C/C++ and graphics libraries.
-To familiarize students with fundamental concepts of computer graphics such as pixels, resolution, coordinate systems, and raster display. -To develop skills in implementing basic drawing algorithms like DDA, Bresenham’s line, circle, and ellipse algorithms. -To provide practical experience in 2D and 3D transformations including translation, scaling, rotation, reflection, and shearing. -To enable students to implement clipping algorithms like Cohen–Sutherland and Liang–Barsky. -To help students visualize 3D objects, projections, hidden surface removal, shading, and animation basics. -To develop the ability to design basic graphical applications using C/C++ and graphics libraries.
-The lab typically includes 10–12 experiments covering: -Implementation of DDA and Bresenham’s Line Drawing Algorithm. -Drawing Circle and Ellipse using Bresenham’s and Midpoint algorithms. -2D Transformations: translation, scaling, rotation, reflection, and shearing. -3D Transformations: translation, scaling, rotation. -Line Clipping Algorithms: Cohen–Sutherland, Liang–Barsky. -Polygon Clipping Algorithms: Sutherland–Hodgman. -Window-to-Viewport Transformation. -Generation of 3D projections (orthographic & perspective). -Implementation of Hidden Surface Removal techniques. -Basic shading and illumination models. -Development of simple graphics-based animations. -Creation of mini graphics projects (e.g., car animation, house design, bouncing ball). -Each experiment is designed to build students' understanding of how graphics algorithms work and how visual elements are rendered on screen. -Hardware and Software Environment. -Systems configured with Windows/Linux for graphics programming. -Minimum configuration: Intel dual-core processor, 2GB–4GB RAM, 40+ GB storage.
-C/C++ Compiler -OpenGL/GLUT or graphics.h (legacy BGI) -Code::Blocks / Visual Studio / Dev C++ IDE -Each student gets an individual system for consistent practice.
By the end of the lab, students will be able to: -Implement and analyze fundamental 2D and 3D graphics algorithms. -Understand the mathematical foundations of graphics transformations and projections. -Develop small interactive graphics applications. -Apply rendering, clipping, and shading concepts practically. -Gain confidence in OpenGL/graphics programming and animation logic.
This lab builds strong foundational skills required in animation, gaming, UI design, simulation, and visualization. By practicing core algorithms, students learn how modern graphics systems work and develop the ability to build simple graphical interfaces and animations.
