All VRML files, except 'halfdome.wrl' and 'curl.wrl', were hand-written using 'vi'. Perl scripts were used to generate 'halfdome.wrl' and 'curl.wrl'.
All VRML files were tested using 'WebSpace Navigator 1.1' from Silicon Graphics Inc. on a HighImpact Indigo2.
All vertex counts were computed based upon triangle counts generated by 'SDSC WebView', a custom VRML browser developed by the authors.
Screen dumps were made using 'scrsave' and converted to JPEG using the 'SDSC Image Tools', a custom suite of image manipulation tools developed by the authors.
Wireframe images were generated by adding the following OpenInventor node to the top of the appropriate files:
DrawStyle {
style LINES
lineWidth 3.0
}
This DrawStyle node converts all drawing to wireframe and draws lines
3 pixels thick. Such thick lines are needed to make the lines show
up clearly when the screen captures are shrunk and printed.
The DrawStyle node is only supported by WebSpace and is not part of VRML. For this reason, the source code for figures using this node are not provided here.
For most figures, additional point lights were added to brighten the scene in preparation for creating the article's screen captures. These extra point lights have been removed in this source code. The results you get from viewing these VRML files will differ somewhat from the images in the article. This is particularly true with regard to the specular highlights on the brass bands of the treasure chest.
Lighting model vary among VRML browsers. Your browser's results may look different from those in the article.
Texture resolutions vary among VRML browsers. Some browsers reduce texture resolution, losing clarity. Your browser's results may look different from those in the article.
The number of triangles used for the VRML primitives varies among VRML browsers. Your browser may report somewhat different triangle and vertex counts from those in the article.
