00189: star adjustment capability and image based stars

« 00188 | Issues | 00190 »

Summary: star adjustment capability and image based stars

Created: 2009–09–11 20:33

Status: Released

Category: Request

From: frankie

Version: 2.0

Released_In: 2.1

Description:

since brightness levels vary greatly between different displays, people will need some way to specify how many of the brightest stars to draw, and how to represent them on the screen.

this request is for a capability to specify to a star plugin how many of the brightest stars in the catalog to render, and then from that list of stars scale between the following:

  • a specified greyscale color and pixel size that will represent the least bright star of the number being rendered.
  • a specified greyscale color and pixel size that will represent the brightest star of the number being rendered.

bonus points for being able to adjust colors, sizes, and number of stars in realtime via the star node.. but this is not required.

brad Sep 14 2009, at 12:45 PM: This has been implemented and added in the latest build, it now includes a Tcl command interface for setting/getting the various parameters! New command_line/Tcl parameters include -min_col <0.0 to 1.0> -max_col <0.0 to 1.0> -min_size <0.0 to X> -max_size <0.0 to X> -max_stars <0 to X>

frankie October 07, 2009, at 10:55 AM: I also added in the fancy "image based" stars from brad under this issue. Can be turned off by redefining the FANCY_STARS_CONFIG_FILE variable.

frankie April 04, 2011, at 10:55 AM: A note for people searching, the star catalog that is included in EDGE is the common Yale Bright Star Catalogue. You can find more information here.
