This page will go over the basics of Axiom for iPad and all the various setting you need to know about before creating your first simulation.
When you launch the app you will be shown an empty scene.
There is the viewport where you can see the ground plane grid. On the right there is the toolbar which has options for enabling the tools you use to interact with your scene. On the lower left there is the scene outline which lists the various components of your scene that you can select and modify. When you select a scene components it will bring up the controls in the parameter view in the lower right.
To start a simulation you need to emit fluid into the scene. You do this with sources.
In the toolbar select the plus icon to add a source to your scene. You tap on the screen where you want the source to be placed.
When you enable the add option you can tap and drag over an existing source shape to duplicate it. When you release, the new shape will be added to your scene.
You can also remove a source by selecting the subtract icon and tapping on the source in the viewport.
If you want to temporarily add a source to the scene, select the finger icon. When you touch the screen it will place a source and when you end the touch gesture it will remove the source.
