Not a programmer?

This is the programming documentation. If you are not a programmer please

• either visit the user page at asdfg.me/osci/
• or click on the releases tab and download the latest version for your platform

Project setup

1. Download and unzip Openframeworks 0.84
2. Move this project into apps/myApps/oscilloscope
3. Clone ofxMightyUI into addons/ofxMightyUI
4. Clone ofxAvCodec into ofxAvCodec.
5. (This is seriously painful) Follow the instructions in ofxAvCodec/ffmpeg_src/readme.md and compile shared libraries for your platform

Compiling with XCode

1. run scripts/clean.sh
2. run scripts/prepare.sh osx
3. Open apps/myApps/oscilloscope/Oscilloscope.xcodeproject and then Build&Run

Compiling with Visual studio

1. run scripts/clean.sh
2. run scripts/prepare.sh win32
3. Open oscilloscope.sln and Build&Run

Compiling with make in Linux

1. run scripts/clean.sh
2. run scripts/prepare.sh linux64
3. run make && make run ? [subwolf knows, i haven't done this in ages!]

See scripts/readme.md for the full distribution process.

Openframeworks 0.84 vs 0.9

This project compiles under Openframeworks 0.84. Only a few tiny changes are required for 0.9RC2:

• sounddevices.h: Change RtError to RtAudioError
• ofApp.h: Change ofRect to ofDrawRectangle

This project will transition to OF 0.9 as soon as the first stable version is released.

Experimenting with the shaders

Once you have a running version (either compiled or a binary release) you can manipulate the shaders on the fly. The shaders will be reloaded automatically when they're saved. Please note that you're bound to OpenGL2 / GLSL 1.2 (shader 120 with gl_ext_geometry_shader)
