Image Description, by
This is a screenshot of Track Gen from RacecarSims.com. We developed this
program to build tracks for our racing simulation products. The building
process begins with an overhead bitmap of the track for reference. Then, by
adding turn apexes with a radii, Track Gen figures the connectivity of the
circles(crossing or straight, and which side) and calculates the entry and exit
point of tangency to the previous and next circle. Once this track centerline
is defined, the tracks polygons are constructed using parameters such as width,
altitude, bank, and material. Track side features are built with extrusion
objects for things like curbs, fences, stands, signs, trees, etc. The program
also has a component to calculate and export the driver line for computer driven
cars. The screenshots on the bottom are from road-courses that contain only
Track Gen created objects, with the exception of the car and sky dome.
