Miscellaneous

The fourth part is sacrificed to miscellaneous objects – shoes, towels, bottles, umbrellas and others… This part is the last from these four modelling parts, next one – part V will be about rendering the scene. Again I’m sorry for low image quality,but believe me – it’s better for your faster previews :)

Ladder

As you can see in the image, first of all I made  a railing of a ladder – just not to forget :) The first step is to make curves, which we use to make pipes  after. Distance between curves is 600mm.

WIP picture

Type Pipe command, use radius 15mm and flat cap. Okay, railings are done.

WIP picture

We need some steps – Let’s start with simple block:

WIP picture

Turn this simple block into step by chamfering edges wit distance=3mm and by adding cylinders with radius 2mm. Boolean command will blend these surfaces into one polysurface.

WIP picture

Now use Array command to make a few steps from this created one – X=1 Y=1 Z=at least 4. More steps will not be visible,so don’t worry about this.

WIP picture

And this is final model of ladder. You can convert it to mesh, if you would like. This step will save you some Megabytes on you RAM and HDD.

Flip flops

Very typical shoes wear for swimming pool, solet’s  make one pair :) First of all make closed curve appx. sized as your foot print [20-25cm long]:

WIP picture

Use PlanarSrf command to make a surface from this curve. Select created surface and Extrude it. Then Chamfer upper edge with distance 1mm:

WIP picture

Next step is to make holes for strips: create three cones with the same radius.

WIP picture

Use Boolean Difference and right after Chafer inner edges. Holes are done and ready.

WIP picture

Make three 3 dimensional curves as base curves for stripes.

WIP picture

Pipe command will turn your curves into two pipes ready for blending:

WIP picture

Turn off smooth mode [available in T-splines] and delete one face on longer pipe near the middle.

WIP picture

Next step is to weld points, so you get shape like this:

WIP picture

Enable Smooth mode and look at final shape:

WIP picture

If you go back to Rhino mode from Tsplines, your shape will be converted like this:

WIP picture

And voi-lá, flip-flops are done! :)

WIP picture

We can start with another misc. object:

Hat

First of all make an ellipse, select curve, type PlanarSrf command and create surface. After that Rebuild it with 20 by 20 control points, so you get surface like you can see in the image:

WIP picture

Select middle part of Ellipse and move Control points up. Very central part of them move a little bit back down:

WIP picture

Curve side part of hat to make Side wings using control points:

WIP picture

Make the same for both sides:

WIP picture

Select surface and offset it using distance of 2 mm. New offsetted surface is quite difficult,

WIP picture

so rebuilt it with 20 by 20 control points. Okay, surfaces are done, Let’s close them: Command DupEdge will duplicate both edges, so you get clean closed lines:

WIP picture

Select both of new curves and Loft them. Now Check Surface directions:

WIP picture

Join all three surfaces and chamfer them:

WIP picture

Now we need to make a strip around the hat, so follow these steps: Make a rectangle and move it a little bit up:

WIP picture

Use command PlanarSrf again:

WIP picture

Split surface by this hat and delete inner and outer surface, so only middle part will stay.

WIP picture

For the middle part use again command DupEdge, so you will get only edge curves. Make the same trick again, but this time a little bit higher:

WIP picture

Draw a section curve – both ends must lie on previously made curves!

WIP picture

Use command Sweep 2 Rails to make strip around hat:

WIP picture

Hat is done. Now we need some bottles.

Bottles

Create section curve, offset it, join and rebuild:

WIP picture

Revolve command will now make a body of bottle by rotating around middle axis:

WIP picture

Copy a part of bottle faces and use offset, distance 0.1mm.

WIP picture

Follow the last few steps to make another type of bottles:

WIP picture

This model was downloaded from T-Splines:

WIP picture

Another needed thing are towels: First step – make rectangular plane, rebuild it with 20 by 20 control points:

WIP picture

Move the control points to make the planar surfaces look like towel:

WIP picture

Make a few types of towels:

WIP picture

It is also possible to make these towels thicker [2mm] by using Thicken command in T-splines:

WIP picture

Now we can play a little bit with objects to make them non-uniformly looking :)

WIP picture

Okay! This part is over now, You can have a look at this full resolution render:

WIP picture

Next steps are going to be rendered in Vray. I gave a try  to Maxwell, so here is my first touch with this program:

WIP picture
