YESTERDAY'S FUTURE Entry: Mike Perusse

#15

Thanks DickM, The sprite was inspired by the A4, F104, F105 fighter designs. I was trying to use some of the mindset of the jet designs of the 50’s early 60’s. I also was able to see a Marine A4 at an Air show before they were retired. Man O-Man was that pilot having a lot fun flying that jet that day… sure would of been fun sitting in the back seat with a paper bag… anyway, I thought it would be an interesting contrast to the laid back Albatross 2000 LGY.

In regards to this contest: I hit a major time drought the last 2 weeks and a learning curve with Nurbs. I really haven’t done much in the way of Nurbs. I’ve been reviewing Cristo’bals Sentinal Tutorial and comments made by PaulS about the tut. as my modeling philosphy in EIM… which turns into a lot of trial an error on my part…

But I’m keeping my positve spin on this contest - I’m learning, I’m modeling when I can, and I am enjoying the time I’m getting to play… :slight_smile:

Back to the day job…

Hi All,

It’s been a good week of Nurbs based trial an error in EIM.

This model is probably a real scrapper for the pros, but for me… Yeee Haaa…
I’m Making some progress.

Thanks to the 3DNY and Cristobals tuts I’m actually understanding some of this good stuff.
Now it’s practise, practise, practise so I can figure out how to do it right.

Any how another late night… got to go. Image attached.

Cheers, MIke

By the way, I do have some EIM questions, just need to get to the point of asking them the right way. … goodnight… ~mike

#18

Nice going Mike! I’m happy to see you struggling with EIM because I am struggling with Silo…
I usually use only FormZ but for the kind of shape I’m looking for, Silo is a better tool. If only I could use it more efficiently…

Keep up the good work!

#19

Congrats mike but the modeler if hard to learn in the start, but the interface is cool…

I m spectacting for more picture of you work…

cheers,

So here is one pain… Everytime I look at my Profile Skin for the main body of my aircraft It reminds me of my younger days when that great old Aunt with her lips all puckered up coming after me to give a big wet kiss…YUCK!

I’m using Nurb Curves, With 4 cross sections, end tolerance has varied in my experiments along with the number of intermediate xsections.

Anyone have any suggestions on taking the pucker out of my profile… I’m a bit stymied.

Thanks,

Mike

mike, you can interesed for sphere surface and after surface edit, only push s and x together you can scale in x o s and y scale in y or s and z together, and this form do the shape.

I do it very more times, if i can i start the shape from any type of surface presets… and i edit it.

I hope help you…

Its best less profiles if the shape is armonious, in the pic there is the profiles for the shapes and the edit form from sphere surface.

You can understand me?

If the shape have lines more straigh line forms then need it more profiles…

For you i think that this form with less profiles in the cross-section ( final procedure for profile skin ).

Too, you can a revolve nurbs, one nurbs only and then edit the shape, if you do nurb from profile, for you can curvature continuity in the shape in start and finish then you have to put three clicks in the begining of curve and finish in the curve.

i send this files to you…

#22

Hi Miseka,

I was able to explore your files and work with your suggestions for a little while tonight.
I clearly have been making things a bit more complicated then they needed to be.

I will do some more work on my model and send it to you later this week for some more feedback, if that is ok.

Thank you very much for your help,

Mike

#23

Its ok always… :wink:

I do it with like.

Im waiting your files.

bye

cheers

#24

You know as much as I loved EIM, I only touched the nurbs tools a few times.

#25

Progressing just the same.

Well I’m trying to stay postive. I’ve been struggling to get “good” time for working on this project. I also did a rebuild on the model. I used a single nurbs curve, revolved it and edited the surfaces. I Also rebuilt all the wings. I’m understanding birails better, but still don’t always understand why a end surface doesn’t get capped sometimes.

From a EIM perspective, its been a good play in the sandbox project.

A lot more to accomplish in 3 weeks… Oh Boy… just not sure how it’s going to go.

Umm lets, I did a tweak on the wings the original concept shows them with an downward arc, but when you look at a modern glider it doesn’t quite work that way. So for glider flight the wings will be at positve angle. During landing they will drop so that the wheels (to be modeled) in the emergency rocket pods will hit the ground.

With that my wife has knocked on the floor above… so time to leave my sandbox and call it a day.

Cheers,

Mike

#26

Thanks a million Miseka… your EIM help opened up my eyes a lot…

At some point I do need to talk about this model more with you.

Thanks,

Mike

#27

In the research images I’ve reviewed the end of wings are rounded…Any suggestions on how to round wing tips? I was thinking I would need to use Profile SKins for the Vertical/Horizontal Stabilizers and Main wings.

Thanks,

Mike

#28

Hi, and thk for replys…:wink:

Here i send files for you question, i dont know if they are ok for you.

I hope that yes.

See you forum…

pd; i have a files up to 97 kb, i dont put here ?

bye

#29

i dont put files more that 97, i how up files of more kB?

i send you the file for outlook mike33.

bye

I continue to move forward but I am stymied by my lack of constant EIM use and understanding the best modeling work flow for an aircraft.

As noted in another thread I am battling the level of detail. My analytical side wants to build an aircraft, the artist side wants to make a free flowing 3d sketch… The engineering approach vs the Fred Gambino approach [Fred had a way of using simple shapes to make some cool aircraft].

I was also having boolean issues, but then I realized I didn’t really want to join or subtract
parts and pieces of parts…:hmm: which kind of leads me back to the analytic side of things where I want to model an aircraft that sorta works… so much for my KISS approach.

This right side/left side brain issue has basically been my artistic achilles heal for the last decade. It’s kind of like chaos theory and fractals… the more I dig, the deeper I dig the more I find and the deeper I dig. A whole in the ground for a plant turns into a direct route to New Zealand [Hi Peter Jackson] from the Connecticut River Valley of Massachusetts…

anyway… I have to admit I am very happy I haven’t gotten to the point where I’m modeling rivets. :slight_smile:

Cheers…

Mike

PS PLEASE MAKE SURE YOU READ THE CGTALK ORPHAN WORKS THREAD

#31

I continue working my model. though much slower… life things happen…

Sent a FACT model to work to do some lunch time lighting studies.

Won’t be finished by the 30th but hope to do what I can by then…

A quick image was uploaded from EIAS…

Cheers,

Mike

#32

Don’t despair Mike, you’re doing great! :thumbsup: Still many hours left.
…And at the last minute, what’s one night without sleep? :argh:

The fun thing about concept work is concepting and letting your imagination fly.
The hard thing about concept work is letting your imagination fly and sitting next to a
coworker who flies a stunt plane in his spare time. He sent me this link:

Reality and the rules of physics has a way of making concepts seem rather funny…
I must admit I laughed an awful lot as each aspect of my “glider” was shot down.

Anyway it’s been all in good fun and even though I do despair and get frustrated with my reality from time to time I do love doing this stuff.

Thanks for the vote of confidence Rick,

Cheers, Mike

Howdy All,

Well here’s the link to my image:

http://homepage.mac.com/spottedskimmer/.Pictures/Doodles/Albatross-unfini.jpg

It’s not done. But I thought I’d post where I was able to get to anyway.

I learned new things with this contest which is what I really hoped for.

Great job everyone else, you have all inspired me to keep trying to get better at using EIAS and EIM.

I end this contest on a very, and unrelated, happy note …I was finally able to rototill a 13 foot x 30 or so foot garden tonight at our new home… using a rented hydraulic tiller:love:… before it rained. It went smooth as silk with very few rocks… I can’t wait to start some planting…

Cheers,

Mike
