Description

The Priscila project was born as an example application for the GNU/EDMA project, able to show how simple and easy can be a GNU/EDMA program at the same time than performance is not seriously degraded. As a video worths a million words, check the video below to know what we are talking about.

PRISCILA is a simple SDL/OpenGL presentation application with keyboard-based WYSIWYG built-in editor... its aim is to provide a vi-like tool to write presentations. Current editor is still very rudimentary and several edition actions have to be done by editing text files.

Each presentation slide is a real 3D scene composed of several items. Special effects can be applied to modify item appearance, and actions can be added to modify items behavior. 3D objects, effects and actions are GNU/EDMA objects, providing automatically : Plug-in support, easy update, etc...

PRISCILA uses basic OpenGL. The graphical performance is not impressive, but it can work with minimal 3D support (for instance on netbooks with intel graphics cards).

Current PRISCILA version is Alpha. Use it at your own risk :). The basics works. You can add slides with text, images and simple 3D models, the main drawback is that adding animations is a manual operation at this moment. The good thing is that it is simple, light and does what most people use in their presentations.

I have used PRISCILA in a couple of real presentations, and I can say that with good acceptance :).

NEWS

April 2010

Released version 0.4.1 suporting GNU/EDMA 0.18.x

• Uses new GNU/EDMA classes repositories to keep PRISCILA classes isolated
• Remote control using Bluetooth. Client for Symbian S60 an OpenMoko availables
• Included action components, allowing to execute special action when a slide item receives an event
• Included a generic animation FXs. This has been available in previous versions but not announced
• Preliminary support for passive stereo rendering but this has not been tested

January, 2007

Version 0.1.10 (release 10) of priscila includes the following improvements:

• New command line for extra functionality.
• Transparency on 3D Models.
• External text style definition.
• Unicode support (I hope :).
• Lots of Bug Fixes.

July, 2006

New version 0.1.10 of priscila includes the following improvements:

• New Shadow Text item. Add it in edit mode pressing 'p'.
• Basic File Selector to include images and 3D objects in presentation.
  Press 'i' to insert images and 'o' to insert 3D objects
• Some Bug Fixes

Features and Status

Every item in a Priscila slide is a generic 3D object supporting the following transformations: 3D translation, rotation and scanling as well as Color blending and tinting

Slides can contain the following slide items:

• True-Type Text: Text in slides can use True-Type fonts for smooth render and scalation
• Images: Images of different formats (SDL_Image lib used to load) can be added to each slide. Images are managed as OpenGL textures so smooth zoom, blending, etc... is directly supported.
• 3D Objects: 3D objects can be added as any other item. Currently supported format is 3ds.

Each slide item and the slide itself can be associated to one or more FX. Currently available FX are:

• Slow-Zoom: The indicated item is zoomed very slowly
• Spining Object: The indicated item is rotated in one or more axis
• Flying Quads: A dynamic background where random rectangles of different sizes, position, velocity and transparency moves in one direction all together.
• Simple Animation: Fix an initial and final property set and this effect will calculate every intermediate step. Works on position, rotation, scale and color properties. Animation start time can be controlled.

Built-in editor supports:

• Object selection in slide
• Object positioning, scaling, rotating and blending
• Object bring to top and send to back
• Simple text insertion
