Hi, i have noticed that sometimes my graphics card it going at 2 FPS when displaying an assembly of 500 cubes inside 2-3 unions-differences. My graphics card can display 16trillion vertices per nanosecond and and has liquid nitrogen heatsink assembly. What is the speed because? Is the program sending a giant raft of data to the graphics card on every frame? What is the bottleneck due to? what are the codes in openscad that communicate with the graphics card? is it DX or GL based? Please tell me where are the library functions that regulate the graphics card vertices and array inputs? Is the entire coordinate system sent to the graphics card and rotated? where is the camera object in the openscad code? is it moving around the object? -- View this message in context: http://forum.openscad.org/graphics-card-speed-in-openSCAD-tp13909.html Sent from the OpenSCAD mailing list archive at Nabble.com.

Hi Torsten, Did you get the OP as an email from the list? As I didn't, nor any of his other posts, so something is off. If you did get an email could you forward it to me so I can check out its headers etc. Thanks, Michael On 20 September 2015 at 02:50, Torsten Paul <Torsten.Paul@gmx.de> wrote: > > Because: > > https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/FAQ#Why_is_the_preview_so_slow.3F > > And also: > > https://github.com/openscad/openscad/wiki/Project%3A-Improve-OpenGL-rendering > > ciao, > Torsten. > > _______________________________________________ > OpenSCAD mailing list > Discuss@lists.openscad.org > http://lists.openscad.org/mailman/listinfo/discuss_lists.openscad.org >

All of ufomorace's emails go into my spam folder, despite me continually marking them as not spam. Google doesn't like his email address.

The path for the forum post is 1) Original Post nabble.com (forum) 2) Mail server nabble.com 3) emwd.com (mailing list) 4) Receiver (gmx.de in my case) Just using the mailing list it's different as Nabble is not in the path, only emwd.com. ciao, Torsten.

Have you checked your spam folder? I get all of his emails, so they get sent OK from the mailing list. I just have to dig them out of my spam.

Yeh, as Nophead said, they were in my gmail spam folder. Trouble is I have that account forwarded, so I don't see the spam unless I go looking. It said that his yahoo address did not pass the yahoo checks (called from gmail). ufomorace - you may want to check you yahoo mail account. Lots of people on the mailing list use gmail and your posts get sent to spam. > -----Original Message----- > From: Discuss [mailto:discuss-bounces@lists.openscad.org] On Behalf Of Torsten Paul > Sent: Sunday, 20 September 2015 7:19 AM > To: discuss@lists.openscad.org > Subject: Re: [OpenSCAD] graphics card speed in openSCAD > > On 09/19/2015 11:01 PM, Torsten Paul wrote: > > On 09/19/2015 10:46 PM, Michael AtOz wrote: > >> Did you get the OP as an email from the list?

Hi there, Thanks Torsten i'll have to learn some new graphics concepts. it is a very complex renderer. For my email, here is what happened. I subscribed 4 months ago to as a single question and i wasn't familiar with the software. I took the individual messaging by mistake and i recieved 50 emails that were about development that i didn't grasp. I thought it would be ok to put the mail to the spam folder for the time being until i could find the unsub buttons, and the mail at the time was fine on subscription. I figured out the program and had to be on the list again and i subbed again except that my email isnt recognized. Sorry about that. It's difficult to keep things tidy on the pc. :\ -- View this message in context: http://forum.openscad.org/graphics-card-speed-in-openSCAD-tp13909p13917.html Sent from the OpenSCAD mailing list archive at Nabble.com.
