Week 1 (part 1): Overview and Introduction to Graphics Research

• Recomended reading: chapter 1 of the suggested textbook (Hill, F.S., "Computer Graphics using Open GL") and the C/C++ tutorial below.
• Demo programs: same as for part 1 and 2 of the tutorial below

Week 1 (part 2): Introduction to OpenGL

• Recomended reading: chapter 2 and sections 3.1 and 3.2 of the suggested textbook (Hill, F.S., "Computer Graphics using Open GL")
• Demo programs (requires installation of GLUT):
  • Example 'OpenGL Examples': Available as Visual Studio solution OpenGLExamples_VS10.zip.
  • Example 'House 2D': Available as Visual Studio solution House2D_VS10.zip.
  • Example 'GeometricPrimitives': Available as Visual Studio solution GeometricPrimitives_VS10.zip.

Week 2: Illumination and Shading

• Recomended reading: Sections 8.2, 8.3 and 8.6 of the suggested textbook (Hill, F.S., "Computer Graphics using Open GL")
• Demo programs (requires installation of GLUT):
  • Example 'Shaded Cylinder & Light Demo': Available as Visual Studio solution ShadedCylinderAndLightDemo_VS10.zip.
  • Example 'Light and Shadow': Available as Visual Studio solution LightAndShadows_VS10.zip.

Week 5: Modelling and Rendering of 3D Objects

• Recomended Reading: Section 5.6 and 8.4 of the suggested textbook (Hill, F.S., "Computer Graphics using Open GL")
• Demo programs (requires installation of GLUT):
  • Blender is a very popular and powerful modelling and animation tool and using it might give you a better understanding of some of the concepts taught in this lecture. You can download it from here and use these tutorials to get started.
  • Example 'Colour Cube + RGB Cube': Available as Visual Studio solution ColourCube_VS10.zip.

Week 6: Modelling with Polygon Meshes

• Reading: Section 3.5 and chapter 6 of the suggested textbook (Hill, F.S., "Computer Graphics using Open GL")
• Extra material: Derivation of the formula for a "Surface of revolution". You get the formula by rotating each curve point using the matrix for a rotation around the z-axis: DerivationSurfaceOfRevolution.pdf.
• Demo programs (requires installation of GLUT):
  • Example 'Extruded Surface': Available as Visual Studio solution ExtrudedSurface_VS10.zip.
  • Example 'Parametric Curve': Available as Visual Studio solution ParametricCurve_VS10.zip.
  • Example 'Parametric Surface': Available as Visual Studio solution ParametricSurface_VS10.zip.
  • Example 'Surface of Revolution': Available as Visual Studio solution SurfaceOfRevolution_VS10.zip.
  • Example 'Catmull-Rom Surface of Revolution': Available as Visual Studio solution CatmullRomSurfaceOfRevolution_VS10.zip.

Week 11: Ray Tracing

• Reading: Chapter 12 of the suggested textbook (Hill, F.S., "Computer Graphics using Open GL")

Week 12: Texture Mapping

• Reading: Section 8.5 of the suggested textbook (Hill, F.S., "Computer Graphics using Open GL")
• Demo programs (requires installation of GLUT):
  • Note that the routine for loading ppm-files is very slow when executed in debug mode. Please compile in release mode.
  • Example 'Textured Brickwall': Available as Visual Studio solution TextureMapping_VS10.zip.
  • Example 'Wattie Can': Available as Visual Studio solution WattieCanTexture_VS10.zip.

Week 12: Spline Curves and Surfaces

• Reading: Chapter 10 of the suggested textbook (Hill, F.S., "Computer Graphics using Open GL")
• Demo programs (requires installation of GLUT):
  • Example 'CurvesAndSurfacesDemo': Available as Visual Studio solution CurvesAndSurfacesDemo_VS10.zip.

• Part 1: If you work in the lab you will use the Visual Studio IDE. Please read the tutorial "Introduction to .NET" which explains how an OpenGL project is created using MS Visual C/C++. We have two versions:
  • IntroductionTo.NET Screenshots created using MS Visual C/C++ 7.0 under .NET 2003.
  • Introduction to MS Visual C++ for MSVS2008.pdf Screenshots created using MS Visual C/C++ 2008 under .NET version 3.5.
  Note that newer versions of .NET might have a slightly different user interface. Note that the tutorial shows only how to build C/C++ applications using OpenGL. If you you want to create an application with C# you will need CsGL or the Tao framework which implements most of the OpenGL/GLU/GLUT syntax but is not an offical OpenGL implementation.
