Making a Roman Coliseum

Author: yaniko

Tools Needed

  • Bryce 5

Introduction

This tutorial does not claim to carry out a real reproduction of the true Coliseum.

Its goal is to show you how multi-replicate works, and what you can do with it.

Step 1 - Making a wall

Making a wall with an aperture is rather easy.

The wall is composed of a positive cube (see under),

a negative cylinder …

and another negative cube…

The three objects are grouped to form the wall.

(dimensions are given as an indication. They will help you to make the project easily)

Step 2 - Making some details (1)

Let's add an additional detail like this one (under)

You'll only have to group the previous three elements with a negative torus…

placed against the 1st cube …

Step 3 - Making some details (2)

Another detail consists of a simple cube placed under the aperture..

Here is a first render of our wall:

Step 4 - Making some details (3)

Let us add some other details, by positioning a cube as indicated under.

You'll have now to use a very interesting property of Bryce : the multi-replicate option…

Say you want to repeat 2 times the rectangle, by moving it downwards and reducing it : enter the value of the height displacement, and reduce by 95% both its length and its width…

Step 5 - Making some details (4)

300-033b.jpg

Here under is the result….

You may add other details, like this column for example…

( the creation of the column presents no difficulties)

300-033c.jpg

And here is the final render…

300-033d.jpg

Step 6 - Choosing materials

300-033e.jpg

Choose a stone matter, like this one for example..

(reduce the bump height to 10 )

You should obtain this rendering ( front view)…

Step 7 - Making of the entire monument (1)

300-0340.jpg

First of all, go to top view.

Click at “show origin handle” in the attributes.

You must see appearing a green point (the origin) in the medium of the figure.

Move this green point far from the “wall”, corresponding to the radius of your “virtual coliseum ”.

300-0341.jpg

Let us use multi-replicate once again, with the criteria indicated here:

44 objects (either 45 with that the duplicate one)

rotation of an angle of 8' (45 X 8 = 360 ') *

Scaling and displacement with 0.

300-0342.jpg

* the angle depends on the distance displacement (the “radius” of the coliseum)

Step 8 - Making of the entire monument (2)

300-0343.jpg

You should obtain this…

(in top view)

Or that…

(in Director's view )

300-0344.jpg

and this one with materials…

300-0345.jpg

Step 9 - The End

Group all the objects, duplicate 3 times the set (displacements = 0, H, 0 with h=height of an object, here 66 with the values taken since the beginning, no rotation nor scaling)

Have a drink or go shopping…(depends the speed of your PC)

You should obtain this…

The Famous Roman Coliseum !

That's all Folks !

Have a Good 3D.
