Performance Targets

Metric Target
Number of strokes 1000
Memory footprint (PROCESSOR) 32mb
Memory footprint (VIDEO) 16mb
Disk «scales» «gracefully accepts user limit»
CPU Utilization average 20% of a 600mhz processor


Goals

Codename FREEKS is a Java+OpenGL implementation of the essentials of K-Sketch. Its primary goal is to implement an efficient OpenGL, (ES-compatible) renderer for OpenKSK files. We must be able to port this renderer to an OpenGL ES platform, re-implemented in C (or Objective C).
OpenGL ES 1.1 notes

The first pass is going to be a Java implementation, to allow us to deliver K-Sketch via the web.
Some other goals:

  • Embeddable architecture, which would allow us to embed K-Sketch in other programs
    • * A more flexible renderer and item manager, allowing graphics and strokes to be rendered and selected without any hacky crap
* Dynamic quality settings for strokes. The stroke data format needs to support variable quality. It should probably support bezier representations out of the box, as some kind of smoothing transform
