This is a tutorial on how to use the Kineme GL Tools to create a simple line drawing composition.

You’ll need the following plugins and macros:
kineme.net/QuartzComposerPatches/StructureTools/0.1
kineme.net/release/AlphaBlendMode/10
kineme.net/release/GLTools/16
hybridvisuals.nl/downloads/vdmx-mouse-macro/

Installation instructions can be found on the respective sites.

As mentioned, I really would love to hear your feedback on the new style of commentary. I feel it’s a lot less boring, but I hope you can still follow everything. Let me know

Linear Value Translation qcClip

This is a Quartz Composer Clip macro, that allows for a linear translation of a variable number. Basically you can use it to translate a number within a certain range (say [0,1]) to a new range (say [-1,1]). Fill in the old and new ranges, and attach the input. The patch will take care of the math for you.

Place the .qtz file in ~yourhomefolder/Library/Application Support/Apple/Developer Tools/Quartz Composer/Clips. It should then be available from the patch creator window.

Inputs:
value – the value to be translated
oldMin – the old minimum of the value (ie 0)
oldMax – the old maximum of the value (ie 1)
newMin – the new minimum of the value (ie -1)
newMax – the new maximum of the value (ie 1)
