This is an image I'm going to turn into a water-colour/drawing type of
image, so I haven't made a lot of detail or textures. It was quick and
great fun to make.

Thanks for watching.

You say you didn't give lots of attention to the detail or textures, but the
road sure looks realistic - the closeup part of it to the camera. Looks
almost exactly like the real thing at high speed - how did you do it?

It does look good, and presumably that effect is because the camera is
moving at high speed to keep the image of the car sharp.  But if this is
the case, the other parts of the track should be blurred too, like those
hemispherical markers...

No, nothing is moving, it's just squeezing and stretching of a simple
pattern, like this:

pigment {
  granite
  color_map {
   [0 color rgb <1,1,1> *0.4 ]
   [1 color rgb <1,1,1> *0.7 ]
  }
  scale <300,3,300>
}

The racetrack is just a difference of a cylinder and a cone, some 5000 units
radius. The effect is somewhat exaggerated by the camera position and
angle.

Well it's definitely effective and satisfying to look at :)

A similar effect to that employed by a chap called Brett Dickson in his IRTC
entry for the last round:

Very inventive, I think, both of you!
