Bryce Tutorial 01: Multi-replication

Time: approx 1 hour for beginners, 30 mins for Bryce practitioners.


Level: assumes no prior Bryce knowlege


What will I learn: familiarisation with Bryce tools and workspace; orientation in 3d; create simple 3d objects; multi-replicate 3d objects; production of complex patterns of objects using multi-replicate function.


Introduction: Bryce is a very versatile easy to use 3D environmental modeling and animation package. This tutorial will take you through the steps neccessary to generate complex 3d patterns. You will learn how to use the powerful Bryce Multireplicate tool to achieve this.


 

Multi-replication

Open Bryce.


Menu File > Document Setup > tick to optimise Bryce to your monitor size. Note to expose the application Menus you have to roll the mouse over the top edge of the screen to expose them.

Click the grid floor plan, menu Edit > Clear. You now have a blank 3d space with one camera to work in.


Create a sphere by clicking the blue sphere shape - a red wire-frame sphere will appear in the Bryce workspace.


Click the Sky & Fog workspace menu. Click the Simple White Background sky. Click the tick to select it - this also closes the box).


Add a material to the surface of the sphere. Ensure the sphere is selected by clicking it, click workspace menu Edit to open the Materials box > click Metals > select Christmas Ball #1 in the top left. Click the tick to select the material and close the box.


Do a quick test render by clicking the Fast Preview button below the trackball on the left of the workspace (it will dimple in but nothing will happen yet. Then click the bigger Render button next to it - see a nice red sphere render.


Now is a good time to save your project. Menu File > Save As to a filename and location of your choice.


Press the keyboard Esc key to cancel out of the render and return to wireframe mode.


We are now going to Multi-Replicate the sphere. Menu Edit > Multi-Replicate and experiment with the following values - leave the other cells of the Multi-Replicate box as default - and tick to select which closes the box and initiates the multireplication.


 
 

Quantity: 20

Offset: 0, 25,0

Rotate: 0, 0, 0

Size: 100,100,100

Result: Column of 20 spheres - Do a test render, then cancel the multi-replication by keyboard Esc > Del.


Quantity: 20

Offset: 25, 0, 0

Rotate: 0, 0, 0

Size: 100,100,100

Result: Row of 20 spheres along the x axis - Do a test render, then cancel the multi-replication by keyboard Esc > Del.


Quantity: 20

Offset: 0, 0, 25

Rotate: 0, 0, 0

Size: 100,100,100

Result: Row of 20 spheres along the z axis - Do a test render, then cancel the multi-replication by keyboard Esc > Del.


Quantity: 20

Offset: 25, 0, 25

Rotate: 0, 0, 0

Size: 100,100,100

Result: Row of 20 spheres 45 degrees between the x and z axis - Do a test render, then cancel the multi-replication by keyboard Esc > Del.


Quantity: 20

Offset: 25, 25, 25

Rotate: 0, 0, 0

Size: 100,100,100

Result: Row of 20 spheres 45 degrees between the x and z axis sloping 45 degrees upwards into 3d space - Do a test render, then cancel the multi-replication by keyboard Esc > Del.


Quantity: 20

Offset: 25, 25, 25

Rotate: 0, 25, 0

Size: 100,100,100

Result: Classic 3d spiral - best viewed by zooming right out using the XYZ Camera Control above the Trackball - Do a test render, then click the Group Object button (G in the control to the right of the spiral. This groups all of your spiral so it can be manipulated as a single entity. Select and keyboard delete the original sphere. We are now going to multireplicate the spiral. Menu Edit > Multi-Replicate and enter the following in the Mult-Rreplicate box.

Quantity: 1

Offset: 0, 0, 0

Rotate: 0, 0, -180

Size: 100,100,100

Result: a double helix.

Note - the more shapes and lights you include the longer the render time. Once you are happy with a composition, save and perform a higher resolution render by clicking off the fast render button.
