Using Present3D

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:

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 "a" key separates the data by luminance and the "t" key will increase the transparency 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.

This works as described above.

 

Using the Flight Manipulator

This is toggled on or off by using the "2" key.
