Using Present3D 

Start a Presentation as normal using the on screen menu or the P3D loader application. You can also start from the command line :

Starting a Presentation using the command line

Open terminal and "cd" change directory to the location where the Present3D presentation file is located. Then run using the command:

present3D file.xml

The presentation file.xml will be loaded.

Moving through your slides

The following key commands will allow you move throw the presentation slides in different ways.

• The left and right arrow keys allow movement back and forward through the slide in a presentation.
• The up and down arrow keys allow movement through the layers in each slide.
• The "a" key will start the presentation running in auto-play mode.
• The "n" key will auto step through the slides and their layers.
• The diagonal keys beside the "help" and "del" will jump between the first and last slide respectively.
• The "p" key will pause all rotations and movies.
• The "o" key will resume all rotations and movies.
• The "r" key will reset the slide, so all movies/animations will start from the beginning.
• The "c" key will hide the cursor.
• The escape key will exit Present3D

Interacting with objects

A three button mouse is useful when interacting with presentation content. However a single button mouse can be used, and the modifier keys "alt" and "command" can be used to replicate the middle and right buttons respectively.

The three buttons do as follows:

• Right button with up and down movements will cause the object to zoom in and out respectively.

• Left button will object to be rotated.

• Middle Button will move the position of the object in 3D space.

• The "space" key will reset the object to its default position.
• The "l" key toggles dynamic lighting on and off.
• The "k" key will allow you to move the light source if your model has normals.
• The “w” key will change the model to wireframe view
• When using Volumetric data, the "u" key separates the data by luminance and the "i" key will increase the transparence of the volumes layers.
• When using Point Cloud data. the "+" and "-" keys will increase and the decrease the point size of the data.

Manipulators

Present3D has four main manipulators, Trackball, Flight, Drive and Terrain.

Using the Trackball Manipulator

• This is toggled on or off by using the "1" key.
• This works as described above.

Using the Flight Manipulator

• This is toggled on or off by using the "2" key.
• The left mouse button will cause acceleration and the right mouse button will cause deceleration or a backwards movement. Clicking both the left and right mouse button will cause an emergency stop.

• The right mouse button and push up/pull down to zoom in/out.
• The left mouse button and move the mouse to translate the models position.
• The middle button to rotate or travel over the surface of the model, when close in terrain following will be enabled.

Other key Commands

• The "z" key will start recording a motion path. Pressing "Z" (shift-z) will stop the recording.
• The "f" key will toggle between full screen and windowed mode.
