- RENDERER USED:
- Blue Moon Rendering Tools 2.4.0.3 (2.4c)
- (http://www.bmrt.org/)
-
-
- TOOLS USED:
- mops
- (http://www.informatik.uni-rostock.de/~rschultz/mops/) for
- modedlling
-
- The Gimp (http://www.gimp.org/) for making the texture and
- adding copyright tag to the final image
-
-
-
- RENDER TIME:
- about 34 hours.

-
- HARDWARE USED:
- Intel Celeron 412 MHz, 128 MB RAM, NetBSD-1.4_BETA

- IMAGE DESCRIPTION:
-
-
- Nothing particular exciting; this image shows the Spirit of St.
- Louis, the Ryan aircraft of Charles Lindbergh, on its flight acress
- the Atlantic from New York to Paris. It is believed that this flight
- and Lindbergh's following PR campaign in the US was historically
- very important for the development of commercial aviation.
-
-
-
- DESCRIPTION OF HOW THIS IMAGE WAS CREATED:
-
-
- All modelling was done with mops, although still in beta stage this
- modeller is already quite capable. It produces RIB (RenderMan
- Interface Bytestream) output suitable for BMRT and PRMan.
-
- Rendering was done with BMRT 2.4.0c.
-
-
- GEOMETRY
- ~~~~~~~~
- Most of the geometry consists of NURB patches that were created
- using the "Build From Curves" function in mops. The engine cylinders
- are mostly created from CSG objects and some "sweep" NURB objects
- for the fuel and exhaust pipes, although these are not clearly
- visible in the final image.
-
- The sea under the plane is a simple bilinear patch, the wave
- patterns on it are created by a displacement shader.
-
-
- SHADERS
- ~~~~~~~
- This time I did not write any custom shaders but could get along
- find with only more or less 'standard' shaders that can be found on
- the web. RenderMan shaders are small programs written in the
- 'RenderMan Shading Language', where almost anything in texturing and
- deforming geometry is possible.
-
- I used one custom-painted image map to project the Label on the
- front part of the aircraft's fuselage.
-
-
- RENDERING
- ~~~~~~~~~
- The image was rendered using Larry Gritz' splendid Blue Moon
- Rendering Tools, using a volume shader for the atmosphere effects,
- two area light sources, motion blue and radiosity. The latter is
- barely visible in the resulting image, but for some scenes it can
- greatly improve realism.
-
- Peak memory usage of the renderer during rendering was only 28 MB.
