Patches item #410412, was updated on 2001-03-21 16:06 You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=303248&aid=410412&group_id=3248 Category: None Group: None Status: Open Priority: 5 Submitted By: Mathias Gumz (bz-akira) Assigned to: Mathias Gumz (bz-akira) Summary: noise renderer Initial Comment: i improved the performance of the jamming noise renderer a lot, but there are still problems with mesa. with the nvidia-0.9.767 this patch rocks and is damn fast, no performance slow down any longer ... regards bz-akira ---------------------------------------------------------------------- >Comment By: Mathias Gumz (bz-akira) Date: 2001-03-29 06:43 Message: Logged In: YES user_id=178399 documentation is for whimps :) .. just kidding. i could make the radar whatever you want. i just want to hear more meanings. for example the use of one static texture ( or better the full texture, because now i swap the texture coords) is a good idea for mesapeople, but perhaps they wanted their old noise back ? ... so the mesausers should realy stand up and say, HEY MAN, this is what we want :) regards, mathias ---------------------------------------------------------------------- Comment By: Gert Brinkmann (gbrinkmann) Date: 2001-03-29 06:12 Message: Logged In: YES user_id=48712 You should describe this in the documentation then you can answer "RTFM" if one asks. ;) Or another idea: Make the radar noisy but only once. So the noise is not moving because of no refreshes. I think this is a good choice. It really should be kept simple and CPU-cheap on low detail. This is what this option is good for. All things switched off by this option value should be described in the man-pages.

Ideal for slow machines and bad mesa-implementations? Gert ---------------------------------------------------------------------- Comment By: Mathias Gumz (bz-akira) Date: 2001-03-29 03:04 Message: Logged In: YES user_id=178399 the problem of mesa is, that its a softwarerender... so the improvement shouldnt be signifikant. and perhaps mesa isnt able to handle textures quite goof. for example chestal or someone else told me, if he stands direct in front of a wall (the wall filled up the screen) the performance sunk rapidly. glDrawPixels() (the old method) transfers the pixels from the procmemory over the bus. mesa transfers _all_ over the bus. so if mesa is faster with glDrawPixels than with textures, we should perhaps #ifdef some things ... but therefore i need much more reply of the mesausers and their experiences ... regards, mathias ---------------------------------------------------------------------- Comment By: Tim Riker (timriker) Date: 2001-03-29 02:26 Message: Logged In: YES user_id=8134 This did indeed fix the white screen. Performance under software mesa is about 15% slower with the flag than without. The old method was about 10% slower. So it does not seem to make a lot of difference with software mesa. I'll do more tests though, I expected it to be a little faster, and I'm wondering why it's not. ---------------------------------------------------------------------- Comment By: Mathias Gumz (bz-akira) Date: 2001-03-29 01:57 Message: Logged In: YES user_id=178399 and ... solved :) i think the problem is, that i dont use the bz-internal texturething. if someone changes the resolution, the texture will be lost, perhaps because auf building a new openglcontext. the white screen on tims screen by using the first patchversion was the same problem. the texture was lost somewhere ... but i dont know yet, how bzflag handles the different contexts and/or visuals ... any suggestions, please mail me bz-akira ---------------------------------------------------------------------- Comment By: Tim Riker (timriker) Date: 2001-03-28 21:00 Message: Logged In: YES user_id=8134 when changing resolutions under XFree86 the noise goes away and a white screen is shown instead. ---------------------------------------------------------------------- Comment By: Mathias Gumz (bz-akira) Date: 2001-03-28 01:11 Message: Logged In: YES user_id=178399 1.texturenoise will shown even when disabled texture 2.use now GL_NEAREST -> "harder" noise (for hh =) and thats it ---------------------------------------------------------------------- Comment By: Mathias Gumz (bz-akira) Date: 2001-03-22 07:49 Message: Logged In: YES user_id=178399 improved some other things (noisequality) and now mesa should render the new noise right .. but i need feedback from mesa-users. so feel free to mail and diss me, regards, mathias ---------------------------------------------------------------------- You can respond by visiting: http://sourceforge.net/tracker/?func=detail&atid=303248&aid=410412&group_id=3248 |
