+ This animation (left) simulates a scanning of a combustion medium by the
+ laser sheet that emits from the left part of the medium, and propagates to
+ the right. Each frame is computed by <a
+ href=man/man1/htrdr-combustion.1.html>htrdr-combustion</a> for a different
+ position of the laser sheet, that subsequently intersects with different
+ zones of the medium. Each image represents what is perceived by the camera
+ for this particular position of the laser. The configuration used for this
+ simulation is the one retained for the validation of the algorithm (the
+ corresponding data set is provided in the <a
+ href=htrdr-combustion-spk.html>starter-pack</a> for combustion processes): as
+ shown in the representation of the medium data (right), the volumic fraction
+ of soot follows an axisymmetric profile, with the main axis centered in the
+ cubic chamber, and a maximum at the back.
