Suggestion: Rendering frequency when following map-center
« on: August 11, 2012, 13:00:01 »
Hi Menion,

today I observed how the vector map is moved "piecewise", when you travel for example by car and the map is centered on my position. As soon as my position is updated (the GPS interval is propably critical) the map is moved and the new parts are rendered. This results in "stuttering". My idea is to introduce a smooth rendering by applying a refreshing rate greater then 1 Hz (may be 5 Hz). This has to be of course evaluated concerning cpu-usage and is only necessary, if the map is moved. I guess it should be possible to estimate the direction the map has to be moved.

This is of course just an idea for you to consider.

Peter

Hi Peter,
  this is of course interesting idea, anyway I'm trying to do as less operations as possible. Rendering map on display is one of features that affect battery (cpu) a lot. Locus also still use just CPU (software rendering) for rendering of map and not a graphics card support (hardware rendering) so till this will be done, I also really cannot (do not want) to do such feature. When hardware rendering will be done, this will be for sure implemented

Hi Menion,
sure, this was just an idea. I already guessed that for now such a feature is too stressful for battery lifetime.
