« 00541 | Issues | 00543 »

Summary: increase drawstar plugin performance

Created: 2015–05–22 11:15

Status: Released

Category: Request

From: frankie

Version: 2.3

Released_In: 2.4

Description:

the dsp_drawstar plugin, which is used to draw the star field on the background, runs slower than it needs to. This is a request to make it run faster.

Comments

frankie April 12, 2016, at 12:07 PM: This has been done. Performance is greatly improved. Also, the star rendering is done now in shaders which can be specified by the user in the stars config file. See configs/fancy_stars.cfg as an example, and the default shaders under "shaders/stars.fs" and "shaders/stars.vs".
