English: This is my rendering of the Smalltalk Balloon. It came into being almost, but not entirely, unlike the other painted and drawn renditions.
The special thing is this: The picture was created completely in Smalltalk! Inspired by the famous August 1981 BYTE cover I modeled the island and the balloon in 3D Studio. This three dimensional model was rendered with the line drawing renderer I developed in my diploma thesis.
The Smalltalk renderer analytically calculates visible parts of the polygons in the scene. The resulting pieces are colored according to the light and written to a PostScript file. On top of these faces a line drawing is created by smoothly drawing contours with splines. Again, the line width is adjusted to reflect the lighting (kudos to Lars Schumann for the drawing library). The whole process from loading the model to writing the file took about one minute on a Pentium 90 with VisualWorks 2.5.

This is my rendering of the Smalltalk Balloon. It came into being almost,
but not entirely, unlike the other painted and drawn renditions.
The special thing is this: The picture was created completely in Smalltalk!
Inspired by the famous BYTE cover I modelled the island and the balloon in 3D Studio.
This three dimensional model was rendered with the line drawing renderer I developed in my diploma thesis.
The Smalltalk renderer analytically calculates visible parts of the polygons in the scene.
The resulting pieces are colored according to the light and written to a PostScript file.
On top of these faces a line drawing is created by smoothly drawing contours with splines.
Again, the line width is adjusted to reflect the lighting (kudos to Lars Schumann for the drawing library).
The whole process from loading the model to writing the file took about one minute on a Pentium 90 with VisualWorks 2.5.
