How to deform ovalish object

rumcajs

OK, I can use that technique next time. Right now, it is going well. I have finished the front (just basic shape).

Have you remark that the blue one is like Iron man!

rumcajs

Blue color of the skin? Or what?

I have found one complication. Because the scull if rounded - the faces are rounded. But the at front, there are two rectangles (vertically) - 1) nose and eye corner 2) month and chin ... and then he draw on this places he has them streight like rectangle. But I have to create triagles instead. So I separate every rectangle to 2 triangles. This slows down. If there would be any feature to simplify work - to make the 4 edges of rectangular parallel to create rectangle, then it would be much more simple. This takes a lot of time, still. I use construction lines, but they are from "From" view so they don't fit from Top down view. That also slows down the work. Many of zooming into very detail, then I place the starting point of new line onto edge (still in "From" view). Then zoom out "Zoom extents" then finish line.

I also found some 3D eye maybe in French? Now I moved one line to form eye whole and add the eyes. You can check. I will check the plugin sure.

I wanted to learn to draw, so this way of working with 3D modeling on simplified models, that's for me the right thing to learn to understand and remember human body proportions and perspective.

Edit:
The video. This way of editing is very inaccurate. Even he did not use human photo. I would rather need plugin to simplify faces.

So if you have triangles like that:


_______
|     /|
|    / |
|   /  |
|  /   |
| /    |
|/     |
--------

I would hover over that those triangles, and then I would click force the edges to form rectangular. That would be really great simplification for that what I would like to. Because there are many rectangle shapes, on which you can draw next rectangle shapes. But I don't have that. I have triangles. And that s*ks..

Edit2:

Although small in size, the eye is a very complex organ. The eye is approximately 1 inch (2.54 cm) wide, 1 inch deep and 0.9 inches (2.3 cm) tall.

The blue one was the primary form not subdivided

If you really stay with SU for modeling such thing i believe that you must use TT Vertex Tool by Thomthom !

About the eyes :

Structures Rayon de courbure antérieur............. Rayon de courbure postérieur
Cornée ................... 7,8 mm................................................. 6,8 mm
Cristallin............ ...... 10 mm................................................... 6 mm

Well this looks much more better. I corrected cheek bones, because the circle on right side keeps perfect geometry!

What i need correct now are the triangles right side around the eye. There must be vertical rectangles! (One big rectangle)

Interesting. But it has side effects. When I would like to reduce these two triangles to get skewed rectangle (one polygon), so it can not hold the bordering edges.

This is result:

So it just removed the border edges, instead, I would want first change the borders a litle bit to fix flat polygon. It looks that this plugin is not based that way, because they want to keep the original shape (?).

Edit:
I did not tried the proj. plugin, but what does it mean to extrude segment?

pilou

For reduce number of polygone by Whaat

For extrude a segment in any direction Projection by Didier Bur (last tool of the toolsbar)

You can't have a losange or a 4 segment surface so a polygon if these 2 triangles are not on the same plan!
You will have always 2 triangles!

It mades that SU can't made with the native tools!

Very useful!
And works of course with multiple sélection! So curves etc...

Here the vertical move but you can make any 360° !

PS and it's repeating! So new selection is the new position of the segment! etc...

If you want scale the segment draw another segment somewhere and scale the 2 segments in the same time

OK. then there could be solution to correct triangles which are created when you create some line. I will show image, what I mean, wait.

Maybe that is not good example...

rumcajs

Projections will be very useful, but does not solve actual problem. And how can I change division number? I tried enter, tab, f4, f5, nothing helped.

pilou

Try tools on surface by Fredo 6
It's useful for draw on curvated surface!

for your triangle that will be not a "flat" triangle because you are on curvated surface!
So a curvated triangle

rumcajs

Then I need to transform the curved faces to flat faces.

pilou

If you flat the "rectangle" some faces around it will be deform too

rumcajs

Pilou, I have opened the document, selected the object and checked the window Soften Edges. There are 0°. So it is really not object with curved faces. Maybe there some conversion happened without me to be aware. Strange. All lines are no dashed no, but I don't remember that I would do some conversion.

So there is not a way how to arrange two planes on the way, they to be on the same plane?

pilou

kill all segments where is the rectangle
draw the rectangle and fill the holes around it with new segments

Do you know

This is not exactly what I need, but similar and interesting.

You have a better one with the same name Clean Up by Thomthom

If you use the previous Projection by Didier Bur, It's a game's boy to make parallal in any direction with it!
and any number just redraw one from the last

or this one Edge tool Divide face by thomthom

I did it in different way:

Side view:

But it is slow work. It took me few minutes to make the lines parralel. Then I used Created faces tool from utilities.

You see that it is possible to do it. Hence now I need only plugin to make two lines parallel. Or 2x2 parallel. Is there some for it? I did it just with my own estimation (just observing/comparing) because I don't the technique to do that accurarely.
