BioSphere

The purpose of this tutorial is to explain what BioSpheres are and the tools in the BioSpheres work shop.

BioSpheres are spheroids with positive and negative properties that interact with each other.
They are used to create custom shapes and foundations for models.

These are the tools in BioSpheres


The menu at the bottom of the work space in Biospheres controls biospheres and not objects.
So if you save you are saving a biosphere file same for open.

To create a new biosphere click on new at the bottom of the work space window.

A new biosphere will appear in the work space window.

Notice the 3 green lines with the numbered indicators, it is the biosphere's tools.
Each individual biosphere has these tools on them.
When you see this tool on the biosphere, it means it is the selected biosphere.
When a biosphere is not selected it will have a red dot in the center of it, even if it is negative and not visible.
When you create another biosphere by pressing new it will appear right on top of the selected biosphere
and have the same properties as the one selected when you clicked new.

To select a biosphere you can use the choose option at the bottom of the work space,
but unless you named each individual one they will all be called untitled,
So the easiest way to select one is to click on it's red dot.

There are four ways to move a biosphere
You can click hold and drag on the sphere tool in the upper left corner.


Or you can use the movement tools

Or you can click hold and drag on the center of the biosphere it's self, the red dot or where the green lines intersect.


On the rotate and bank pull down menu you have a Position option.

Here you can place precise number values to position the selected object.
To learn more about this position menu, see the tutorial on Position Menu.



You can use the rotate and bank tools on the selected biosphere.


Locking axes works in BioSpheres, but the axes in each view are like your always looking in front view.
An example is in front & back view when you lock the Z axes the movement is front wards and backwards.
With the Z axes locked in top & bottom view the movement is up and down in reference to front view.
In other words if you are in top view with the Z axes locked and use the zoom tool the biosphere moves
backwards or forwards, when you go back to front view the biosphere has moved up & down.
This is true to in all the other work spaces except Composer. But in all the other work spaces
except Composer it is the camera that moves and not the object. In BioSpheres it is the selected
biosphere that moves.

Editing the biosphere's properties.
All the edit tools are used by click holding and dragging.


The left arm of the biosphere's tool is Oblateness, it stretches horizontally and flatten's vertically.
You can adjust it on the biosphere or at the sphere tool in the upper left corner.
The number indicator will give you a read out from 1 to 100.

The right arm of the biosphere's tool is Radius. It enlarges the biosphere radius.
You can adjust it on the biosphere or at the sphere tool in the upper left corner.
The number indicator will give you a read out from 1 to 100.

The bottom arm of the biosphere's tool is energy and inverse matter.
It set the size but more important it set how much the biosphere is attracted to other biospheres.
Positive numbers attract. Negative numbers make it inverse matter which is invisible and repels
other biospheres. You can cut a holes or take out slices of positive biospheres with negative ones.
You can adjust them on the biosphere or at the sphere tool in the upper left corner.
The number indicator will give you a read out from 100 to 0 for positive and -1 to -100 for negative.



The Scene Control tools affect all the biospheres in the work space window.
Threshold changes the energy values. each biosphere retains their relative values
to each other. Increasing the threshold value, lowers the biosphere value.

There is a number indicator in the upper right side which reads out the threshold value from 1 to 999

Smooth makes the biospheres smoother when you preview and generate them.
To enable it place a check in the box.

Preview lets you preview the biospheres to see what they look like.
If you try and rotate the preview, it will go back to the biosphere view.

To use the biospheres as a shape or model you generate it.
Then it will become available on the choose menu in other work spaces.
