LPMT is a little projection-mapping tool for use in our office, it is developed in C++ using OpenFrameworks. It’s based on simple quad warping paradigm, and, though rather simple, can be used to achieve complex and professional projection-mapping sets.

This is the up-to-date version of lpmt, based on OpenFrameworks 007

DOWNLOAD:

At the moment LPMT is only available as source code, and we've only tested it on linux systems but thanks to the multi-platform nature of OpenFrameworks it should work out-of-the-box on Windows and OsX too.

up-to-date code (git repository): http://gitorious.org/projection-mapping

for the github fans, the repository is mirrored here: https://github.com/hvfrancesco/ProjectionMapping

MAIN FEATURES:

• up to 36 independent layers (remember you can use a solid black quad even as a mask)
• possible content: solid color, images, video, live-cam, slideshows, smoothly changing solid colors, and more ...
• independent opacity setting for each content element
• customizable green-screen (chromakey) for video and live-cam sources
• horizontal and vertical flipping for image, video and live-cam content
• customizable colorization for each content element
• customizable video speed and volume
• save/load project set to/from xml file
• syncronized start for video elements
• vertex snap function for adjacent quads
• cam snapshot background for rough positioning of quads
• customizable speed for slideshows and color transitions
• synced multi-projectors shows
• control and setup through a rich set of OSC messages

KEY COMMANDS:

’s' – saves settings to xml (projection_settings.xml in data folder) ‘l’ – loads settings from xml file

‘a’ – adds new quad ‘>’ – go to next quad ‘<’ – go to previous quad '+' - raise active quad position in layers pile '-' - lower active quad position in layers pile ‘z’ – selects first gui page for active quad settings ‘x’ – selects second gui page for active quad settings ‘c’ – selects gui page for active quad corner position fine-tuning ‘q’ – fills window with active quad ‘1’ – shows general settings page of gui

‘g’ – toggles gui (for quad warping with mouse gui must be switched off) ‘f’ – toggles fullscreen mode ‘w’ – toggles cam snapshot window background

‘spacebar’ – toggles projection/setup modes ‘r’ – resyncs all videos and slideshows in all quads to starting point ‘p’ – starts projection ‘o’ – stops projection

‘m’ – connects to a MostPixelsEver sync server

TODO:

• quad masking (needs some OpenGL-fu)
• a timeline (?)
• grid warping
• edge feathering for multi-projector shows
• overlay modes for quads
