New component overlays main view and handles middle clicks/drags
to performing rewinding. Also sports smooth transitioning back to
current projection whenever the mouse button is lifted.
Next up, the same kind of transitions in the displayed values.

* Both components now support brushing (support in Scatterplot for
activating a brush is still incomplete, though it can be brushed
on by other components)
* Added a handler for linking the brushing between components
* Added crosshair geometry handler to geometry lib
* Fixed issue #15
|
|
|
|
|
|
* Modified main() function to connect signals/slots to display
calculated values
* Color scales are no longer shared; they are also normalized to
each component's own data
* Stub mouse handling in BarChart (changes cursor shape)
|
|
* The Colormap component is a simple rect with a texture mapped
that displays a ColorScale with a fixed number of samples. This
number of samples is exported as a member const, which is used
on other components (such as VoronoiSplat).
* The texture mapping is reflecting the colormap lookup used in
VoronoiSplat.
* The ColorScale class now has a method for sampling the color
scale and outputs the samples to iterator-style objects,
providing easy intergration with existing code.
|
|
* HistoryGraph replaced by BarChart
* HistoryGraph not removed from code, might be useful in the future
|
|
|
|
* Added voronoi-like splatting to points: the same technique from
Messias et al., (2014)
* It is now possible to change the projection technique during
runtime (possible, but still requires some work)

- geometry.h for geometry calculation functions
- scale.h for implementations of scales (currently only the linear scale)
- updated main_view.qml for the new HistoryGraph component
- HistoryGraph displays each subsample used as a mini scatterplot (no colors
currently)
- Scatterplot now uses scale.h for transformations
- Code cleanup and some bug fixes
|
|
|
|
- Selection linking between subsample plot and main plot
- Dumb "effectiveness" coloring
|
|
- New continuous color scale class;
- Improvements in signal handler for calculating distortions;
- Implementation of the NP(k) measure.
|
|
- Scatterplot: can now map any floating point data to colors;
- Scatterplot: somewhat optimized geometry/material updates;
- Removed anything related to labels where it was not necessary;
- Added observers to implement distortion (via measures) visualization;
- Added skeleton implementations of NP and silhouette.

Interaction still does not work due to signals not being correctly emitted.
|
|
- Removed unnecessary UI elements from QML file;
- Added the ColorScale class and implemented glyph color mapping from class
labels;
- Mark geometry nodes of individual glyphs as dirty when updating the scene
graph.

and placed all scatterplot drawing code inside the Scatterplot class.
