Combine letters for BRL-CAD into one 3D modelBRL-CAD
Status: ClosedTime to complete: 48 hrs Mentors: SeanTags: 3D, modeling, rendering

We had six GCI tasks to model the individual letters of "BRL-CAD".  Combine them into one model and render the completed scene.

You'll have to manually model the dash.  As all of the letters were modeled with different material properties, you may need to model a ground plane ('half' primitive) to see them but the goal is to compose together a "scene" that is visually interesting.  Just lumping all the letters together isn't going to cut it.

Richard, that looks great, but it does look like it really needs a ground plane ("in ground half")... and that blue is a bit yucky... :)  Maybe try applying a metallic property or a checkerboard with the letters sitting on the ground.  With some shadows and ambient lighting, that should look much much better.  How long did it take you to figure out how to pull all the models together?


 

Sean on December 15 2012 05:42 UTCTask Needs More Work

One of the mentors has sent this task back for more work. Talk to the mentor(s) assigned to this task to satisfy the requirements needed to complete this task, submit your work again and mark the task as complete once you re-submit your work.

Richard Akira Heruon December 15 2012 05:50 UTCThank you for your suggestions

I'll work on it later. It took me about 1-2 hours to figure out and to put all the letters properly. 

Sean on December 15 2012 06:09 UTChow long

How long do you think it'd take you if you had to do it again, knowing what you know now?


As for creating the ground plane, these steps should help:



  • run the "in" command, e.g., "in ground half" and it'll interactively prompt you

  • after that, add it to a region: r ground.r u ground

  • e ground.r

  • Go to Combination Editor

  • select the shader button

  • add the stack shader

  • click the add shader button and add checker

  • click the add shader button and add mirror

  • apply, close the combination editor window

  • run this to render it pretty:  rt -s1024 -c {set ambSamples=256}

  • run this to render it on white: rt -s1024 -W -c {set ambSamples=256}


Shouldn't take more than a couple minutes to do that, but it's important to make it look snazzy.  This image is going to be a highlight about the program sent to our news channels (viewed by tens of thousands) after GCI is over, so it's worthwhile to make it look great.  Your name will be credited along with the other modelers.


If you get stuck on ANYTHING or have a question, please don't hestitate!  It's really neat to see how this is turning out!

The deadline of the task has been extended with 1 days and 0 hours.

Richard Akira Heruon December 15 2012 06:32 UTCShouldn't take more than an hour.

However, I'm currently having other commitment. I should be able to start working on this in 4 or 5 hours from now. 

Richard Akira Heruon December 15 2012 09:11 UTCReady for review

The work on this task is ready to be reviewed.

Congratulations, this task has been completed successfully.

Sean on December 17 2012 06:19 UTCwell done

Well done, thank you for making the updates.  If you keep an eye out for our news announcement after GCI is over (if you join the brlcad-news mailing list), you'll see a slightly modified version of your work headlining the article.  Thanks again!


There are several other modeling tasks that you may want to take on!

This combined logo image will probably highlight our summary article on GCI.
