Tutorial - Complex Figures

Imp076

Step 1 - Create Primitives figures

Open 3DSMAX to create Primitives Objects like on the next scheme:

Ellipse: Select in Menu -> Create -> Standard Primitives -> Sphere.

(Radius: 12, Segments: 32, Move: [-18,-8,0], Rotate: [0,105,0], Scale: [210,125,100])

Torus: Select in Menu -> Create -> Standard Primitives -> Torus.

(Radius 1: 14, Radius 2: 5, Segments: 24, Sides 12, Move: [24,-24,0], Rotate: [-5,-28,2], Scale: [100,100,100])

Teapot: Select in Menu -> Create -> Standard Primitives -> Teapot.

(Radius: 16, Segments: 4, Move: [18,16,0], Rotate: [0,0,0], Scale: [100,100,100])

Tube: Select in Menu -> Create -> Standard Primitives -> Tube.

(Radius 1: 9, Radius 2: 7, Height:32.5 Segments: [5,1,18], Move: [42,40,0], Rotate: [0,0,0], Scale: [100,100,100])

Helix: Select in Menu -> Create -> Shapes -> Helix.

(Radius 1: 11, Radius 2: 3, Height: 40, Turns:5.3, Enabple in Viewport, Radial Thickness: 2.21,

Move: [-22,21.5,0], Rotate: [0,0,0], Scale: [100,100,100])

You should get primitive objects like ones shown on the screenshot:

Imp001

Now Export the current file to *.3ds. Select Menu -> File-> Export...

Imp002

Save this file as ImportsObjects.3ds

Imp003

Now open W3DEditor v2.2 and select Menu -> File -> Import 3ds...

Imp004

In the first time, do not change defaults values, and open the file. Press Open.

Imp005

Select ImportObjects.3ds in the folder where it was saved.

Imp006

The first result of the Objects imported has a very bad quality. As you can see Poxels have not the shape of Primitive objects, but that is not a problem.

In next steps we will solve it.

Imp007

Step 2 - Ellips

For clear your workplace, press in W3DEditor v2.2 Menu -> File -> New Map...

Imp008

Change Options for Apoxelation process. CheckTop Smooth and Side Smooth,

change Quality Layers Smooth to 0.001. And Open file.

Imp009

Now a more nice result is obtain, but not for all primitives. Only Ellipse it perfect.

In next steps we will improve the rest of the Objects.

Imp010

Step 3 - Torus

As you can see, Torus in poxel shape has not a hole in middle, therefore we should divide the object into parts.

Imp012

In order to do so, go to 3DSMAX, select Torus and Convert to Editable Mesh, in Modify Panel.

Imp013

For making a division, use polygon method.

Imp014

To be able to select an object, choose a way to Circular Selection Region.

Imp015

We must divide torus into 3 parts. Go to Top View and select polygons as it's shown on the screenshot:

Imp016

Disconnecting the selected part, click the Edit Geometry -> Detach

Imp017

Named the object as Torus_p1 and press OK.

Imp018

The next part requeires selecting a similar method.

Imp019

Try to separate identical fragments.

Imp020

Name the second part as Torus_p2 and press OK.

Imp021

Select all 3 parts of Torus to export them to .3ds.

Imp022

3DSMAX -> Menu -> File -> Export Selected...

Imp023

Save as Torus.3ds. Then, go to W3DEditor ->Menu -> File -> Import 3ds...

Select Torus.3ds and watch the results:

Imp024

As you can see, now the Torus is more similar to the original one.
