Full Version: Ultra-efficient vehicle

Show messages:  1-4  5-24  25-44  45-48

All the questions have been answered in the design, but this is not an engineering forum, so you can just have a look at what it takes to do better than 100-kms in one hour on one litre of gasoline.

Your file is called "Backward bike to render.3dm", I thought you wanted a render.

---

Ultra cool! Bravo!

---

I believe that this light is not favorable to the aerodynamism!
Why not a caps bulb ?

---

yes you are right :)

---

yes it will be better with a cap bulb :)

PS :Sorry for the off-topic, but it was fun to see this thing in realistic rendering.

---

A lot of better but there is always a little sharp gap! ;)

else the original...

Sorry for the delay in getting back to this. First, Thank You for the renders! I have been trying to do a render in Blender 2.8 and it's terrible. I don't know what is wrong or how to make it work. You should know that the front 'windscreen' is not! It is just painted on the body to look like a dark-tinted windscreen -- so as not to scare the children. The driver sits facing the rear (!) so a window there would be useless. The rear is clear Lexan. The driver sees through VR glasses which show images from two cameras, which are at the top of that 'periscope'. They are high so that the driver (who sits very low) can see over the cars ahead of him. The cameras are the same distance apart as our eyes, and each camera corresponds to one eye. As the driver turns his head, the cameras turn, so he really feels as if he is looking out from that high vantage point. The two front wheels drive but don't steer. The rear wheel steers. The front wheels don't lean with the body, they lean at a ratio of 1:2 with the body. This is a totally new concept in vehicles, and it all goes together like this because if you change anything, it just won't work! As for that "light" that bothers you: It's not a light. That is the air intake for the engine! The air exhausts behind the front wheels. An IC engine runs an alternator that powers two electric motors, one for each front wheel. An ultra-capacitor serves as a buffer. As for a real front light, I haven't decided quite how I want to do that, so right now it doesn't have one. But I'm leaning toward an array of LEDs, which would be set into the body just below the fake 'windscreen'. These are so small that they are almost invisible from a distance if they are not on. If anybody knows Blender and would like to help me understand why it's not working for me, please send me an e-mail at: tchickox@gmail.com If anyone wants more technical info on the URO (Unidentified Rolling Object) they can contact me there also.

Ask to Chipp Walters it's became a Blender's guru in no time! A lucky man! ;)

Blender 2.8 and it's terrible?
Maybe isn't a software for You.
Some sample with procedural weld nodes and an others older
No there is a red button where it do the settings and render it for you, this is complex software and needs a bit of study is not for everyone, maybe you have to consider using keyshot.

A free cool one for Moi (maxi 1920 *1080) without any headaches is SimLab Composer Lite ;)
https://www.simlab-soft.com/3d-products/simlab-composer-lite.aspx

just don't export from Moi in 3DM but in OBJ with any options!

Made now in 10 minutes. attached the file for Blender, but I not here to convince you to use Blender only a demonstration If you know how use is simple, the web is fully of tutorials, if decide to use. but there are many alternative that you can use maybe more suitable to you.






Here a profile of a mechanical engineering student that make all inside Blender, without any others CAD.

Great render pafurijaz !

---

Thanks Finema, is only a try without much work, but I saw the file is without any plausible dimension and seem developed without units. seem developed as an experiment, like a sketches. but anyway here more images with HDRI and normals corrected, because the model is done with mirrored side.

I've watched many Blender tutorials; they make everything look simple, because the person doing it knows what he is doing. But when I try to do things, it doesn't work. The only way to learn something like this (and I believe that this applies to education in general) is to have an knowledgeable person watch what I'm doing and say, "Wait, that won't work! Here is what you must do:" My render looks nothing like yours and I don't have a clue why there is a huge difference. Since I don't know what is wrong, I don't know what to do to 'fix it'. And I don't think the problem is with Blender. If I used another program I would expect to have the same problems. So I've just given up on rendering models until I can see a way out of the no-way-forward problem.

Hi as you said the main problem is thinking is a simple as see on videos that are very confusing, Blender is a complex software, and maybe you don't know the basics for such type of application, is a professional software, and it is fully of features not only the rendering that is a final step for any works, the complexity is in various knowledge and as for others modern path tracer they follow the same rules, Renderman used in movies for most of the VFX is an hardest software even than Blender. To have a nice render you need to take the time and don't give up, many tutorials was made from newbie that don't really understand what is the right way to teach. maybe if you have time start reading some book or get a look on online manual. There is many steps before you know how use it, such as for material physics, like the glass that react in different manner if the have the thickness or not, for metals and many of those now are more simpler with a new node implemented in various rendering engines, the Principled shader developed by Pixar and used in Blender and others path tracer such as AMD ProRender Vray etc. for any materials there is many parameter to tweaking, but anyway if you have time is free great application, and make awesome render.

Blender 2.8 Eevee : render 3 second

@pafurijaz
-Blender is a complex software-

I would use the term: uncomfortable (scomodo-poco pratico)
Complex is the opposite of simple
I do an operation in Cinema4D...same operation in Blender is more uncomfortable
I open Modo or Lightwave and i see a clear UI...open Blender previous versions...a bad UI
Is something wrong in me? I'm not enough skilled..smart..clever ?

What we are doing here?Why we are here and not on Rhino forum?
It's because we use Moi.It's simpler than Rhino.What does it mean?
Do an operation in Moi is more comfortable than do it in Rhino
It doesn't mean that who use Moi is less clever and smart than who use Rhino
It means that Moi is built in a better way than Rhino
It means that Michael (one)is more clever and smart than Mc Neel programmers (many)

...programmers...

It not only happens in 3D software
I'm mechanic mantainance and building in woodworking machines for chairs
Use Moi as CAD,but started 3D in ACad 2000..prompt line command,orient UCS icon for extrude.. :)
I have two tenoning machines to restore, from different brands..they are competitors
If i turn on the display in one, i see a clear,logical interface
not the same in the other..do the same thing need to open more windows,nested menus etc.
I say to myself:Mauro you are not an idiot if you don't understand how it works...that programmer is idiot !

Blender attract so many people,most of all young,because it's free.
I can't pay forced updates or year subsctiptions if i want my external renderer still works into my package.
So i did this jump into Blender...it's free,so no complains..but is uncomfortable :)

Hey Tim..you are ok..just take your time and things will be better :)

A brief thing, without any controversy.
I have seen this continuous comparison for years and all to say that one is more suitable than others software and is true but saying is horrible or other like is an insult to the all people working on these software maybe is more adapt I don't like UI is comprehensible , as you can read from my comments I do not urge or try to convince anyone nobody to use Blender but I would avoid giving certain judgments on something just because I am unable to use.
This also happens with moi3d where some people think they are doing things magically without knowing about NURBS.
And you also seem to be saying things without knowing the story, since Rhino was programmed by Michael.

I used and bought rhino 2.0 and is the same with more feature. I have upgrade to the version 3.0 and left for others Mechanical CAD, SolidEdge, for professional works, Now I totally changed my job.
And I use Blender since 2000 and I made many thing that are impossible for people even right now.

The History of Rhino

May 1992 - First meeting with AG. Applied Geometry (AG) came to us for assistance in integrating their AGLib, NURBs geometry library, in AutoCAD. AG customers included Alias Research, Spatial, Honda, and Tecnomatix.
Jul 1992 - First prototype in AutoCAD after about three days of work
Nov 1992 - McNeel/AG agreement to develop AccuModel, NURBs modeling for AutoCAD. McNeel would do the marketing and AG would do all the development. McNeel would provide AutoCAD development support as needed.
Nov 1992 - Michael Gibson hired as an intern. He brought Sculptura, a mesh modeler that he had done as a class project.
Mar 1993 - Sculptura released
Mar 1993 - McNeel takes over as the lead on the AccuModel development
Jul 1993 - First prototype of Sculptura 2 ready for NURBs
Nov 1993 - Sculptura 2 nicknamed Rhinoceros
Jan 1994 - New McNeel/AG agreement. McNeel licensed AGLib from AG and AG was to provide the needed AGLib enhancements and maintenance.
Apr 1994 - Rhino beta released on the Graphic Alternative BBS. This was our first version of a public beta program.
May 1994 - Dr Dale Lear hired from AG. We had found that we needed in-house geometry expertise to develop the functionality and usability needed by our clients.
May 1994 - Alias Research agrees to purchase AG. Alias was AG's largest customer and they felt that one of their advantages was the geometry technology.
May 1994 - First commercial products completed using AccuModel. Ed Monk & Son Naval Architect released an 82-foot sports fishing boat.
Jul 1994 - Geometry development begins in earnest. Alias didn't seem to be interested in the geometry library business.
Aug 1994 - Sculptura renamed Rhinoceros after it was determined that we would not be able to resolve the trademark problems with AccuModel
Aug 1994 - Private showing of Rhino at SIGGRAPH
Nov 1994 - Sale of AG to Alias final
Mar 1995 - McNeel provides Alias with first installment of geometry technology
Jun 1995 - Alias purchased by Silicon Graphics
Jun 1995 - McNeel receives the last update of AGLib
May 1997 - Last build of AccuModel for AutoCAD. As the Rhino product progressed we decided that it would be better to focus on the Windows version.
Sep 1997 - 50,000 beta sites and growing fast without any promotional effort on our part
Jul 1998 - 100,000 beta sites
Jul 1998 - Announced October release at SIGGRAPH
Oct 1998 - Rhino version 1.0 released
Dec 1998 - First 5,000 shipped
Jan 1999 - Japanese version released
Jan 1999 - First public beta of 1.1 released
Jan 1999 - First European reseller meeting in Barcelona
Mar 1999 - First third-party book on Rhino published
May 1999 - Korean version released
Aug 2000 - First public beta of Rhino 2.0 and Flamingo released
Aug 2001 - Rhino 2.0 shipped

Below NURBS CARs made in Blender in the years between 2001-2003 when we was a few people, now Blender is used in movie for VFX, games and much more and by many studios around the world and is supported from big company.
The problem isn't the software but some times the lazy people.
and here wash i doing now a big assembly of Yacht this model is underdevelopment with over 1000 parts. And Blender is my CAD that I use for developing surfaces to export in others CAD with the help of my own workflow.
