Preview broken with Windows 10 - with difference() #1409

Closed urmilparikh closed 8 years ago

urmilparikh commented 9 years ago

I upgraded my OS to Windows 10 and now I find that preview (F5) is broken in some cases; and that OpenSCAD shows different views at different angles. Render (F6) works fine, as expected.

Seems an issue with difference().

With this example code:

difference() {
    translate([-3, -3, 0]) cube([6, 6, 1]);
    translate([0, 0, -0.1]) cylinder(d=3, h=1.2, $fn=12);
}

I get this with F6 (as expected): good

... but these with F5, at different view angles and at many view angles I do not see anything in preview: bad bad2

Please post the information from Help -> Library Info.

Also check for updated graphics drivers. This type of issues are mostly caused by misbehaving drivers.

MichaelAtOz commented 9 years ago

Check whether Edit/Preferences/Advanced/Force-Goldfeather makes any difference.

urmilparikh commented 9 years ago

@MichaelAtOz: Yes, that fixes the issue.

@t-paul, I'll still update graphics driver and report result without 'Force-Goldfeather' set.

urmilparikh commented 9 years ago

With updated driver as well I see this issue, so Force Goldfeather is the solution.

Thank you!

TakeItAndRun commented 9 years ago

Now, dont close the issue. It should work without Force Gotdfeather

@urmilparikh could you please post the content of the Help -> Library Info window. This has detail information about the graphics driver and the OpenGL context OpenSCAD got. Hopefully that helps to find the root cause of the issue.

Thanks, is that already with the updated graphics driver? The Intel Download Center seems to provide version 15.40.4.64.4256 which sounds quite a bit newer than the one reported in the OpenSCAD info (10.18.15.4248).

urmilparikh commented 9 years ago

I confirmed that Windows still says my driver is up-to-date. It is possible that Windows is not yet installing this new version.

Let's wait for Windows to install new version.

Neon22 commented 9 years ago

I have installed Build 10.18.15.4256 which windows informs me is the latest for my machine. It shows same problem in F9 preview. The "Force Goldfeather" fix works for this build.

Same here:

Works only with the "Force Goldfeather" workaround

@urish Is this on Windows 10 as well?

Yup, windows 10.

kintel commented 9 years ago

Thx - the only theory I have thus far is that this Intel driver is the first one that supports Windows 10, and there might be some initial issues. There are multiple other issues with this driver in other software (found by googling), so it might be worth waiting for an update.

(dev note: A better way of finding such issues might be for us to write a stand-alone OpenCSG test app, as an attempt to reduce the problem to as few components as possible.)

urish commented 9 years ago

Thanks!

Are there any drawbacks for using the workaround? On Aug 24, 2015 5:12 PM, "Marius Kintel" notifications@github.com wrote:

I think the drawback would only be rendering speed.

I'm seeing the same issue. Surface Pro 3, with latest driver from Windows Update. Force Godfather works fine.

rossbagley commented 8 years ago

I just manually installed the 15.40.4.64.4256 driver bundle and it reinstalled the HD Graphics Driver version 10.18.15.4248 (same version as I and everyone else using fully updated Windows 10 has).

And the "Force Goldfeather" worked for me as well. Thank : waiting for rerender was making me code more carefully, but also driving me to use openscad less and less.

trayracing commented 8 years ago

Doesn't occur in OpenSCAD 2015.03, but does in 2015.03-1 and later (including 2014.06.14). I'm on Win10/Intel 4400/driver 10.18.15.4256. Slightly simpler repro case: difference() { cube(10, center=true); cube([5,5,20], center=true); }

trayracing commented 8 years ago

In the two cube difference example, the model disappears when viewed from above or below. It appears without hole from the side. From a certain angle underneath, depending on the viewport size, I can see the either the cube or the hole, but not both. Screenshots attached, including a render of the intender scene, which looks correct. Also, intersection() is not drawn correctly - looks like the first cube from above/below, but second cube from the side. union() looks correct. With Goldfeather enabled all look correct.'

keithjjones commented 8 years ago

:+1: Same issue. Force goldfeather fixes it for me too. Windows 10 here as well. (Not sure why it says Windows 8 below, I am definitely on Windows 10.) It works without this setting on another Windows 10 install that I have.

As of April 3, 2016 this problem still exists with Windows 10, newly installed and updated in February. The fix also works.

michael13162 commented 8 years ago

April 28, 2016, and I'm having this problem on Windows 10 as well.

kintel commented 8 years ago

@michael13162 Does the Force Goldfeather option work? Are you using the latest drivers (Intel drivers are currently at *.4380) ?

(We're still short one Windows dev with an Intel GPU. I guess the former is harder to find than the latter)

michael13162 commented 8 years ago

Yes, Force Goldfeather works, but I have no idea what it means.

Neon22 commented 8 years ago

nobody knows - and lots of people in lots of apps having similar diffculty with openGL drivers for intel chipset. not something we can fix in another way IMHO. we wait for new drivers from intel, or the heat death of the universe - whichever comes first.....

trayracing commented 8 years ago

It broke between 2015.03 and 2105.03-1. That's not a big range of changes to look at.

kintel commented 8 years ago

@trayracing There's nothing done between 2015.03 and 2015.03-1 that should affect this. Perhaps some small 3rd party library change is contributing to this issue. We're using MXE to build dependencies; perhaps something changed there. If anyone has the time to compare Help->Library Info between the three versions 2015.03, 2015.03-1 and 2015.03-2, that would be helpful.

Also, if someone could point to the cheapest possible laptop which demonstrates this issue, that could also be helpful in terms of matching the necessary hardware with a developer.

@donbright @t-paul any idea of who may be interested in helping out if we could acquire the hardware?

June 26 2016: I just upgraded my Dell Inspiron 15 Win7 (Pentium 3558U) laptop to Win10 and found this rendering bug. Selecting the option "Force Goldfeather" fixes it.

@jbeale1 Could you give the latest drivers from Intel a spin? https://downloadcenter.intel.com/download/25977/Intel-Graphics-Driver-for-Windows-10-and-Windows-7-8-1-15-33-

jbeale1 commented 8 years ago

@kintel : This Dell laptop apparently needs Dell proprietary drivers, the generic Intel one warns that it has detected my laptop uses a customized driver and the standard Intel one may not work so I'm attempting to get the correct Dell driver but it's a bit of an adventure. Still trying...

jbeale1 commented 8 years ago

I tried to install the current Intel driver despite the warnings, and it refused to install saying "This computer does not meet the minimum requirements for this driver". Needs a newer CPU I guess (?) I installed the current driver for my model laptop from Dell (Inspiron 3542 Service Tag: BMNY512), which is Intel HD version 20.19.15.4404 Unfortunately, the problem remains, although I can still fix it with "Force Goldfeather".

trayracing commented 8 years ago

jbeale, it's not uncommon. The intel installer appropriate for my HD 4400 on my HP refused to install, saying it hadn't been validated for my system. HP isn't inclined to update drivers, so I remain stuck at 10.18.15.4279 from a year ago. Any notebook vendors that don't play these games?

donbright commented 8 years ago

@kintel it just so happens that my trusty old machine quit working recently and i had to buy a cheapo model from Staples and i got an HP 15-ac161nf which has an Intel HD graphics thingy and it does in fact reproduce this bug on Windows 10(TM)

@trayracing example box is invisible from the 'top' etc etc etc. It just disappears. Rotate to the side and it's fine. Hilarious.

the problem is i don't have much time... i shouldn't even be typing this. im supposed to be asleep. they dont like it when i start snoring in my cubicle.

im also not supposed to be spending time describing what Goldfeather is. and that it's not a thing, it's a person. (Sorry alot of people know this already but someone above mentioned it so here goes)

It goes back to OpenCSG, check out the FAQ http://opencsg.org/#FAQ

or especially this paper by Florian Kirsch (who makes OpenCSG) and Jürgen Döllner

OpenCSG: A Library for Image-Based CSG Rendering

https://www.usenix.org/legacy/event/usenix05/tech/freenix/full_papers/kirsch/kirsch.pdf

Now as their paper describes, OpenCSG works by using various algorithms to fake 3d rendering using only 2d rendering tricks like stencil buffers and whatever. OpenCSG is designed to allow the user to choose which algorithm to use. SCS algorithm is one, Goldfeather algorithm is another,

Goldfeather is Jack Goldfeather... the lead author in a graphics paper that describes the algorithm. Here is the paper he wrote with Monar, Turk, and Fuchs about their ideas

http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=28107&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D28107

Goldfeather actually has a website! He is a professor in Minnesota. Check it out

https://apps.carleton.edu/profiles/jgoldfea/

Thanks Dr Goldfeather, those paper he worked on in the 1980s are helping people workaround a bug in graphics drivers in 2016. Yay internet.

Yes to the idea of Intel updating drivers.... there have been problems with OpenSCAD on Intel HD for many years... but OpenCSG is not using "advanced features". It was created in the early 00s!!! They mention some video cards from over 10 years ago in their paper and those cards would run OpenCSG just fine. So in many cases you would be better downgrading your Intel HD graphics to something like a Ge Force from 2005 lol. Unfortunately not possible on most laptops. Anyways . I don't think Intel / Windows / Whoever is ever going to fix these bugs.

where i would start... with all this... implementing a workaround so users don't have to worry about all this ..... is trying to get OpenCSG's example program (that comes with it's source code, which allows toggling different rendering algorithms) to build under MSYS2. Then see if it is reproducible problem there. narrow it down to whether it's OpenCSG or the way OpenSCAD uses OpenCSG.

urmilparikh commented 8 years ago

Nice info, @donbright :)

kintel commented 8 years ago

@donbright It would be really good to even ship a pre-compiled OpenCSG demo to help people confirm that this is reproducible.

@trayracing @donbright I believe the most likely is the OpenCSG update to 1.4.0. OpenCSG did update some core rendering code in 1.4.0 (a new fragment shader for ID color management), which could potentially trip up a shaky driver.

If we could isolate OpenCSG as the problem, I believe this could be possible to debug, especially if we could send an example app to the OpenCSG author :)

halxinate commented 8 years ago

Sad. IG5500 with latest drivers and win10 - same issue. In addition, with the Goldfeather On, I'm having a ghosty flickering (on the preview rotation) "residue" in the removed volume, plus the color transparency doesn't work for the first object of the assembly (desk), only for the second one. If you reorder them - desk() becomes transparent, and the ladder() - not (possibly an unrelated issue though).

https://snag.gy/1Dqst5.jpg https://snag.gy/tSNda9.jpg

$fn = 80;

difference() {
    assembly();    
    holes();
}

module assembly() {
    desk();
    ladder();
}

module ladder() {
    translate([2,0,0]) leg();
    translate([-2,0,0]) leg();
}

module desk(){
    difference() {
        translate([-2.5,0.5,-2]) color("yellow", 0.5) cube(size=[5,0.5,4]);
        translate([-1.5,0.5,-3]) cube(size=[3,0.5,2]);
    }        
}
module holes() {
    translate([2,2,1.5]) bolthole();
    translate([-2,2,1.5]) bolthole();
    translate([2,2,0.5]) bolthole();
    translate([-2,2,0.5]) bolthole();
}

module leg() {
    color("green",0.5) cylinder(h=10, d=1);
}

module bolthole() {
    rotate([90,0,0]) cylinder(h=5, d=0.2);
}

If we could isolate OpenCSG as the problem... Not that I know anything about OpenCSG, but I just tried the OpenCSG example in 1.4.0 and it looks broken in 1.4.0 compared to 1.3.3. (Built in VisualStudio 2015). 1.4 shows a sphere, then cube, then nothing in a loop. 1.3.3 shows a CSG model spinning. The OpenCSG web site says "On graphics hardware from Intel, OpenCSG does not always work well."

If you can reproduce the problem with a pure OpenCSG example, that would be a good time to report this as an OpenCSG bug. It would be good if someone capable of reproducing this could report it, to be able to quickly respond to any ideas from the authors.

@halxinate see whether https://github.com/openscad/openscad/issues/310 explains what you see.

halxinate commented 8 years ago

Yep, looks like exactly that 3+ years old issue (even though in my case all of the parts are colored and with 0.5 alpha). And it's definitely a separate bug. Thank you for the tip!

Here's a quick clip of the OpenCSG 1.4 example on Intel HD4400 Driver 10.18.15.4279 (https://github.com/openscad/openscad/files/426063/OpenCSG.1.4.example.Intel.HD4400.Driver.10.18.15.4279.zip)

I sent a short description of the situation and a video clip to the OpenCSG e-mail address.

kintel commented 8 years ago

@trayracing thx

trayracing commented 8 years ago

Good news! Florian of Openscad fame responded and has been able to reproduce the issue inside the test app. While Florian believes it to be a driver bug encountered by changes in the last OpenCSG release, Florian developed a workaround. Portability testing now with the intent of releasing an update very shortly.

kintel commented 8 years ago

@trayracing Cool! Please keep us updated!

trayracing commented 8 years ago

I confirmed Florian's change works locally in the OpenCSG example on my Intel GPU.
