Small objects become emissive at distance....

Post #1by Chuft-Captain » 05.01.2007, 11:55

Basically as objects become smaller (as you increase distance or FOV) they appear to become overwhelmed by emissive bright dots.

This may well be a deliberately designed feature in order to make them more visible at distances where they are only a few pixels or less in size, and as such is probably quite a good feature in some ways.
In fact in points and fuzzy modes, it can actually be quite an attractive feature, as it generally activates at quite appropriate sizes (at least with my models), and makes them glow in the distance.

However, this apparent increased emissiveness causes problems in scaled discs mode in 1.4.1. I don't know about openGL paths as I still haven't got a decent graphics card.
Anyway the problem is that the objects get washed out by the emissive behaviour BEFORE their size decreases significantly.
If this IS a deliberate feature, I suspect it's possibly being activated too soon, especially in scaled discs mode.
Smaller objects get "overwhelmed" before larger objects (at the same distance).

This problem has been around in 1.4.1 and earlier releases, and has probably been mentioned by others. Sorry, I haven't had the time to get around to reporting this earlier, but it wasn't too big a deal as I never used scaled discs mode anyway.
In 1.5.0 pre-release's however I think I noticed this problem in fuzzy and/or points mode, perhaps because it's more extreme (or activates sooner) than in 1.4.1.

Here's some captures from 1.4.1 to show the effect...I haven't got 1.5.0 installed on this machine, so I'll investigate 1.5.0 on the other machine and post some 1.5.0 pics for comparison later.
Has anyone else experienced similar effects?

(Note also, the difference in the appearance of the sun between fuzzy and scaled modes).
