Re: [Flightgear-devel] Discussion culture clashes
Actually, I think what he tried to suggest was, that the needs of visuals and the needs equipment like radar should not be mixed. For visuals we need the terrain and all the objects like trees and buildings which are hard on performance. It's a fact that the distances out to which we draw trees and buildings are considerably less than how far we potentially draw terrain (120 km max.) So these things are separated even now - we don't attempt to render random buildings in 80 km distance even if we render terrain. Nobody proposed to render buildings to the visibility range either. Also let me quote what James said immediately before: This is moving in the right direction for sure. I'd like to go a little further, and make the LOD setting a simple checkbox labelled 'reduce detail adaptively'. Then make the LOD ranges (for trees, clouds, AI models, whatever) internal properties, and crucially, enable OSG's LOD-bias feature. This effectively scales the 'visible distance' used to select LOD by a factor, and we can use a PID controller to adapt it based on target and actual frame-rate. (Of course I didn't try it for real yet). This ought to nicely adjust the LOD bias, and hence the final LOD, to keep a target rate (say 30 or 60fps). So this doesn't lead to any more gracious interpretation. * Thorsten -- Everyone hates slow websites. So do we.

Yes, but strangely enough, this part of the discussion happened to be about LOD systems and performance rather than memory usage. And as far as the GPU performance footprint of trees or buildings seems to be concerned, if you don't see them on the screen, they don't take GPU performance.

Are you so sure that it is not what you have done concluding rushy that I do not had read the previous posts and spoofing the rest ??? Wikipedia: A straw man or straw person, (...) is a type of argument and is an informal fallacy based on misrepresentation of an opponent's position. I say: (...) * terrain radar code (which'd be especially useful in low visibility conditions) breaks as it can't probe terrain elevations ahead (...) So one could simply change the terrain manager to never unload terrain if it's closer than 20 km - this would basically fix all problems - Can we do 20 km? It would hep for may things, including radar. Vivian says: We don't load enough for AG radar to work realistically in any case. We probably need something between 50 and 100 k for this , and we're unlikely to accommodate the memory requirements of this, at least for 32 bit systems. As an aside, with custom detailed scenery, memory is already marginal for 32 bit systems, reading comments of the forum. - For real radar, we'd need much more and we can't do this for memory reasons. I say: I do agree with that, but if my visibility is 300 m, I'd be more than happy to take the 20 km ahead resolved in a ground radar rather than having 2 km of real terrain ahead of me. (...) I guess for several applications we'd like to know the terrain out to (far) larger distances than we render it, but here I do see memory issues. That's why I proposed to load a minimum of 20 km, not the 100 km - I agree with Vivian, we can't do realistic distances for radar because of memory issues Lorenzo: the reason to be of the EQUIPMENT is to override the limit of the EYE vision.

The memory consumption of loading 20 km (50 km, 100 km) of terrain is a number in a certain range - we don't need to toss concerns back and forth if we go ahead and measure the number, and we should base decisions on evidence rather than belief if we can get the evidence.
