Previously, this subtree consisted of the graphics tutorials available to people who attended SGI's 4D Graphics and Advanced Graphics courses. All this code was written using true-blue Iris GL. As of Irix 5.1 and beyond, they have been "retired" and replaced with a growing set of programs all being implemented in OpenGL.

OpenGL 1, basic programming
OpenGL 2, advanced programming
Open Inventor, the basics and beyond
Performer 2.0 Class source

• opengl1: OpenGL Programming 1 Course -- Sample Programs

  This subtree contains the software included in the OpenGL Programming 1 class course materials. The subtree contains two libraries, a checkVisual utility program, plus src and binaries demonstrating the following:

  • 01.Windows
    Programs that demonstrate how to create windows and set the background color.
  • 02.Rendering
    Programs that demonstrate the basic drawing primitives, and flat and gouraud shading them.
  • 03.Viewports
    Programs that demonstrate how to set the viewport and the effect of the aspect ratio.
  • 04.Transformations
    Programs that demonstrate how to rotate, scale and translate objects, and set the projection matrix.
  • 05.Scene.Modeling
    Programs that demonstrate how to use use the basic transformations to model a scene. Also, demonstrates how the ordering of effects the net result, and how transformations can be kept independent using glPushMatrix/glPopMatrix.
  • 06.Depth.Buffering
    Programs that demonstrate how to use the depth buffer.
  • 07.Viewing
    Programs that demonstrate how to use gluLookAt() or use the basic transformations to create a polarview viewing perspective.
  • 08.Animation
    Programs that demonstrate how to animate a scene without flicker.
  • 09.Input
    Programs that demonstrate how to get input from the mouse and keyboard, and how to use the mouse position to animate objects.
  • 10.Anti-aliasing
    Programs that demonstrate how to render objects without the "jaggies".
  • 11.Text
    Programs that demonstrate how to render a text string and make sure that it doesn't get clipped prematurely when the raster position goes outside the window.
  • 12.Lighting.Basics
    Programs that demonstrate how to enable basic lighting and set the normals.
  • 13.Lighting.Properties
    Programs that demonstrate how to set lighting properties, such as color, and position, and material properties. Also, programs that show how to position the lights so that it is fixed in the scene, moves with the scene, or moves independently of the objects in the scene.
  • 14.Advanced.Lighting
    Programs that demonstrate how to enable 2-sided lighting, make faster material changes, and enable spotlights.

• opengl2: OpenGL Programming 2 Course -- Sample Programs

  This subtree contains the software included in the OpenGL Programming 2 class course materials. The subtree contains two libraries, a checkVisual utility program, plus src and binaries demonstrating the following in OpenGL-speak:

  • accum:
    programs implementing the accumulation buffer to achieve effects of scene anti-aliasing, depth-of-field, and motion blur.
  • alpha:
    programs implementing alpha blending functionalities including a demonstration of how the depth-buffer and spotlights interact.
  • clipping:
    demonstrates defining and using arbitrary clipping planes.
  • dlists:
    programs implementing display lists including an example performing benchmarking which can be run in either immediate or display list mode, lighting done with display lists, and creating an outline font and displaying it using glCallLists().
  • feedback:
    demonstrates use of OpenGL feedback, where one can toggle in and out of feedback mode.
  • fly:
    program lets user "fly" through a simple virtual world. Input controls enable toggling autopilot, alpha blending, drawing surface normals, reset eye position, as well as MOUSE buttons to move the eyepoint and SPACE bar to cycle wireframe/flat shaded/smooth shaded.
  • fog:
    demonstrates using different types of fog including exponential, exponential squared, and linear as well as altering the density value.
  • nurbs:
    demonstrates implementing nurbs. Includes various methods of drawing a rotating NURBS surface where one can toggle display list/immediate mode and filled/ wireframe/patch mode, as well as drawing a NURBS curve and 2 other different NURBS surfaces.
  • raster:
    programs implementing raster positioning and pixel operations, including creating a collage images, implementations of the glCopyPixels() and glPixelZoom() routines, plus displaying an rgb image and file (and a subimage) in a window and writing pixel data from the window to an image file.
  • selection:
    two programs: 1 demonstrates picking, and the other, selection.
  • stencils:
    demonstrates a simple application of the stencil planes to mask an arbitrary screen area.
  • superfly:
    program lets user "fly" through a simple virtual world. Input controls enable toggling autopilot, alpha blending, cycle thru clipping plane modes, debug mode (print coords), fog, display raster image, drawing surface normals, reset eye position, selection culling, and texture mapping, as well as MOUSE buttons to move the eyepoint, pick a shape and SPACE bar to cycle wireframe/ flat shaded/smooth shaded.
  • texture:
    programs demonstrating implementing textures, including using textures with alpha values, using gluBulid2dMipmaps() to scale and load mipmaps for a single texture image and then applying this to a polygon; reading a texture from an rgb file, setting up the texture and a sphere map texture environment and then applying them; as well as a second version using automatically generated texture coordinates; reading in a texture from an rgb file, setting the texture and the texture environment, then applying the texture to a rectangular polygon using explicit texture coordinates; and a demonstration of storing textures in display lists where the objects are drawn using environment mapping.

• openInventor: Open Inventor Programming Course -- Example Programs

  This subtree contains the software included in the Open Inventor Programming class course materials. The subdirectories are organized in the following way:

  • components:
    contains a viewer supplied by the application and a material Editor in its own separate window.
  • database:
    contains 3 programs, each of which reads in a scene, and displays in either an Examiner Viewer or a Render Area, plus Inventor V2.0 and V1.0 .iv files.
  • interaction:
    contains 5 .aiff sound files, 4 V2.0 .iv files, 6 sample programs, and 4 lab-solution programs.
  • printing:
    program implements easy printing of a .iv file with an SoXtPrintDialog component.
  • text:
    3 programs render command line arguments as
    1. 2D text,
    2. 3D text,
    3. fancy 3D text with a profile and different materials for the front, back, and sides,
    and displays same in an Examiner Viewer. Also includes 3 V2.0 .iv files.
  • texture:
    a directory of texture files including 7 V2.0 and 2 V1.0 .iv files, and a small rgb file.
