Graphic Anomalies
Graphic Anomalies: strange lines and pixelation from the corners of objects at higher resolution.
I am doing a floor-plan for a school and can't seem to get a clean
3D photo render unless I am close into small sections. I need an overall 3D floor plan photo and can't get it.

show's attempts at renders.
Not sure what to do.
I've disabled ceilings.
I've changed the time of day and the month.
No difference than what is shown. Anyone have an idea?

Re: Graphic Anomalies
It has started developing circular graphics anomalies now. I am at a loss as to what is happening.

Re: Graphic Anomalies
What version of Sweet Home 3D do you use?

Re: Graphic Anomalies
sorry for the delay. the version I am using is 6.1a 64 bit version.
the only way I can seem to get rid of the graphics glitches and shadow anomalies is to select all and resize down 20% but it makes all the furniture warp out of shape.

Re: Graphic Anomalies
I found that I get all sorts of lines and graphics glitches if the object I create is over 100m in size. Under a 100m it is pristine and perfect render. WTF?

Re: Graphic Anomalies
Could you try to add a large room at the floor that would include all your drawing?

Re: Graphic Anomalies
OK, I''m not sure I understand that but This is what I've done so far. I have increased the render size with no effect. I increased the actual size of the building (a school) to 200% and found that the shadows and glitches get worse. If I shrink it to 100m or under in size it cleans up perfectly.
I placed an 8000mm wall around the entire building and it made not noticeable difference

Re: Graphic Anomalies
Lucky (or unlucky) me. I'm having the same issue with large buildings. Currently doing a college for a project and i get the same artifacts as dragon.

Re: Graphic Anomalies
Choose Plan > Create room menu item, draw a rectangular room that will include all the other objects already in your design.
If your design already has some room objects, cut / paste them to ensure they appear on top of this very large room.
If your design has multiple levels, be sure to add this special room at ground level, below all other items.

Re: Graphic Anomalies
That worked only slightly and, it wasn't until I put a wall around the entire project and THEN made it a room, that the graphics glitches went away for now. I still have 2 more floors to do before this project is done. I also had to scale the project down form it's original size. 50% of original size. What is up with that?

Posted by alphagreydragon at Feb 14, 2019, 9:36:49 PM

Re: Graphic Anomalies
OK, It didn't exactly work. The moment I added more to the building it started developing the glitches again. I made walls 80000mm tall around the building and made it one room. still ran into the problem. I'm starting to think that this program is not up for the needs requirements of the job.

Re: Graphic Anomalies
OK, interesting development. The PC I've been doing all this work on was a brand new PC put together by our IT department specifically for heavy duty graphics design. it has 16 GB of Ram and a Quadro K620 graphics card as well as a Xeon E3-1245 processor 3.5GHz 64bit windows 10 Enterprise. this is a relatively new PC as I was having sluggish response when rendering and requested a real graphics machine instead of the i7 laptop with 8Gb of ram. it was later discovered that sweet home 3d does not even touch the graphics card and renders only on the CPU. I promptly started getting graphics glitches on the new Xeon processor the more the complexity of the object rendered. It got so frustrating that I pulled out my old i5 laptop (the i7 laptop was returned to IT never to be seen again) and attempted to render all 3 floors of the school I was working on. at the 5000x 2632 highest quality, like the settings on the Xeon, I rendered a glitch free picture of all 3 floors in 3D (it took 15 minutes but worked) so the supposition I have is that Sweet home 3d is incapable of functioning properly with a Xeon processor and isn't able to use a GPU in anything but the most basic (see my pretty picture) way. We have a meeting coming up in the beginning of March to talk about the problems with this program and consider moving to another 3d program.

Re: Graphic Anomalies
If you are prepared to deal with SH3D and get informed about this software, you will quickly realize that rendering in the upper quality levels will not affect the GPU.
And believe me, many users with not so powerful video cards are grateful for that!

Re: Graphic Anomalies
we found out that SH3D doesn't even touch the GPU. everything is done cpu.

You do not have to find out, you can read that here on the website and in the forum...

Re: Graphic Anomalies
Unfortunately the Xeon processor does not make friends with SH3D.
Looking at Sketchup and Revit (I lean towards Revit)

Re: Graphic Anomalies
And with these programs, you will be helped faster and better when problems arise?
Okay, that's all up to you, but I know that all the levers are set in motion when I have a problem with SH3D. And I know that this is not the case with software like you mention. And that's why I know with which software I will be happy in the future, even if not always all problems can be solved in seconds ...

Re: Graphic Anomalies
Sweet Home 3D works well on i7 or Xeon processors (I tried both), but doesn't use the GPU for renderings at the two best quality levels.
alphagreydragon, I'll be happy to read your conclusions about other programs (don't forget to mention their price). At least, I found a solution for your initial problem, but it's too bad you didn't try to arrange any furniture in your plan yet (or show us the results).

Re: Graphic Anomalies
well at any-rate, the Xeon processor in my tower seems to cause the SH3D to spew graphics glitches where as my i5 laptop puts out smooth clean renders from the same file used on the Xeon. Would love to know wtf was going on but suspect that's not going to happen.
IT was a good run but looks like I have to move on. thanks anyways.

Re: Graphic Anomalies
There was no furniture and never would be. it was used to generate a 3D image for future HVAC location layout. spit out a png, cut out specific rooms and set small landing pads for RC Studio readouts of temp and airflow etc. The only time I ever used furniture was on small 3 and 4 floor domestic homes. Not too many graphics glitches and most of them can be cut out or covered over. its when we got to the big buildings like hospitals, 19 floor complexes and schools that we started running into massive glitches, (see original post for effects)

Re: Graphic Anomalies
is this better?

It's a 30+ MB PNG made by:
- exporting your file from SH3D as SVG
- importing it in Inkscape
- saving it as PNG

My guess is that the hatching in part of the floor makes the file so large and may also cause "moire" effects due to magnification or compression, which could be explained as glitches.

Note: My modifications to your file:
- I deleted the oblique wall next to the theatre
- I deleted the floor 80x120 mtr

Re: Graphic Anomalies
I ended up breaking down the file for sections of the building. LL UL middle and R so that the files complexity allowed me to render a 3d image without all the graphics anomalies. It worked enough and I was careful enough that I could stitch together (sort of) a full size graphic for the main presentation page. We have a meeting next week to talk about changing the 3D program and will examine 3 programs, Revit, Autocad and FreeCAD Arch. We shall see what we shall see. Thanks for the assist.
