Create an artistic screenshotBRL-CAD
Status: ClosedTime to complete:
48 hrs
Mentors: Sean
Everyone loves to see screenshots of software in action. We use screenshots in our marketing and outreach. See some of the examples below that we already have.
Create an awesome screenshot of either mged or archer. It should be graphically interesting, show wireframe and/or raytraced geometry and give some sense of capability. The emphasis should be on making a screenshot intended for a non-technical audience. As such, you should show something "pretty" i.e., something very visually impressive and raytraced in high-detail.

Note that we have several screenshot tasks. Note you may have to go through some or our basic MGED tutorials (see docs section on our website) just to be able to display geometry. Finally, give others a chance if you already completed one of the other screenshot tasks. ;)

So that's certainly a screenshot, but I think it fails the artistic criteria. That blob is not graphically interesting and it's not "pretty" or visually impressive to say the least. I suggest converting some impressive 3rd-party geometry (using our stl-g importer, for example) and ray-tracing it within the archer window. There are thousands at grabcad.com and other places around the web. The Stanford bunny or one of their other classis data models would work too (you can google that).
I have problem with stl-g importer.
Where i can see tutorial how to use it ?
I upload a file from .stl to .g ,but when i start it on Archer i cant see it.
I try .ply to .g same problem.

You have to tell archer what you want it to display. Notice the hierarchy view on the left. There's a label that says "all". Try double-clicking or right-clicking that.

I try it but nothing.
I even made a video

Can i use some model of human , tank , tire or download .g files from somewhere ?
You'll find some .g files in your BRL-CAD installation at share/db.
There are nice programs for database creation too. Look at src/shapes and src/proc-db (in the source code check-out) to get an idea what's available. E.g. the program tire creates nice BRL-CAD tires.

... but the model is crap. :)
You need to find some geometry that is more impressive. Try the 'tire' tool that Daniel mentioned or browse through grabcad.com and find something you can import that is impressive. Remember that the emphasis for this task is something artistically impressive.
That chunky human model isn't artistic or impressive. :)

Petar, so I saw your video and the problems you ran into. It looks like the importer failed for whatever reason. I suggest either trying another importer or another model. Converting geometry is a complicated hit-or-miss process, but you should be able to find something that converts nicely easily enough.

That's rather unexpected. Would you also provide the .g file you used to make the image? Lastly, would you also make the camera nearly fill more of the view? 20-30% bigger should do.
Those should be the last two things to close out this task. Thank you for your efforts!

Yesterday when I try to start my computer it shows blue screen,so I send it to the computer store for repair they tell me it's gone be ready next monday . I'm writhing this from my phone and the .g files ,screenshots and original files are on my computer. I realy want to complete this task I work all weak on it, so I'm begging you to accept my task please.

We can wait until then. I look forward to seeing the .g file.

Cho, where's the screenshot? The tasks calls for an image, so I'm not sure what we're supposed to do with a .g geometry file.

Dobromir, thanks for submitting those screenshots, but that model is very boring and the layout of your screenshot is rather plain. I suggest maybe doing some internet research on "awesome CAD screenshot" or similar search terms and seeing what others have done.
Your first step is going to be finding a really cool and artistically interesting model. I suggest browsing a site like grabcad.com and finding a model that you can import into BRL-CAD using one of our importers. Know that importing geometry is HARD and there's not enough time to explain all of the issues, but you just have to keep trying different models until you find one that works. Files in 3DM or STL format will probably work best, and STEP format "might" work if you're lucky. That's our 3dm-g, stl-g, and step-g converters and they're run outside of mged.
Once imported, you can use Tools - Geometry Browser to view the top level objects and render it.

You should also look at our existing screenshots in our gallery. Any screenshot you provide needs to look as good or better than most of the ones in there.
