2016-03-02Improvements related to ColorScale and screenshots.Samuel Fadel
* ColorScale: now a pointer whenever needed. main() takes care of updating extents * New class DivergentColorScale: works specifically for divergent scales, always has 3 colors as input: negative values, 0, positive values * ManipulationHandler: ProjectionHistory no longer needed
2016-02-29Added dialog for saving screenshots with a prefix.Samuel Fadel
2016-02-28Added colormap orientation & improved UI.Samuel Fadel
* Colormap: orientation now enables vertical & horizontal colormap display * Two colormap components, one for each type of point (regular, control) * Improved controls grouping and cohesion
2016-02-12Many bugfixes related to ProjectionObserver.Samuel Fadel
* Correct handling of relative metrics in UI * undo(), reset() methods added * Main class responsible for undoing and resetting both history and the observer (MUST BE AT THE SAME TIME! -- this might indicate a design issue to be addressed in the future)
2016-02-12Code cleanup: enums & properties renamed/added.Samuel Fadel
* VoronoiSplat: alpha & beta are now properties * ContinuousColorScale: enums renamed to the Qt standard way * Scatterplot: internal state enum renamed * ProjectionObserver: observer type enum renamed
2016-02-11Modified the way the history interacts with other components.Samuel Fadel
* Main class is now responsible for updating map components whenever the current map changes (even rewinding): this simplifies other objects because they don't have to know anything about how the data is being displayed later (no CP/RP juggling everywhere) * Added undo/reset actions to main view, including menu items * ProjectionHistory now has specific signals for each change happening to the history
2016-02-09Added TransitionControl and plot rewinding.Samuel Fadel
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.
2016-02-08User can now select RPs & CPs, using the R & C keys.Samuel Fadel
2016-01-29More informative splat parameters.Samuel Fadel
2016-01-29Changed default color scale to a rainbow variant.Samuel Fadel
2016-01-29Fixed screenshot functionality and splat visibility.Samuel Fadel
2016-01-28Simplified layout & options.Samuel Fadel
2016-01-27Regular points now visible by default (and quite small).Samuel Fadel
2016-01-25Scatterplots & splat now share the same scaling.Samuel Fadel
2016-01-21Added second bar chart.Samuel Fadel
Bar charts are now exclusive to the type of points they are assigned to (either CPs or RPs).
2016-01-20Added color scale selection and aggregate error.Samuel Fadel
* Projection metrics can be shown as current, diff to previous and diff to original (original seems bugged, beware)
2016-01-19Updated options & hacks to change color scales.Samuel Fadel
2016-01-18Smaller colormap view.Samuel Fadel
2016-01-18Removed unused menus.Samuel Fadel
2016-01-18Corrected colormap z value so that it is always on top.Samuel Fadel
2016-01-18Updated options.Samuel Fadel
* Added separate controls for the regular and control points scatterplots * Added tickmarks to opacities
2016-01-17Options panel: Reorganized and added some new stub components.Samuel Fadel
2016-01-17Added option to toggle the visibility of scatterplots.Samuel Fadel
2016-01-17Removed menu to change techniques.Samuel Fadel
2016-01-17Added/changed a few visualization options.Samuel Fadel
2016-01-17Added a options panel.Samuel Fadel
* Added screenshot action that saves two images: one of the main view (plot + splat) and one of the bottom view (bar chart) * Added methods/signals/slots to Scatterplot for handling glyph sizes * Added methods/signals/slots to VoronoiSplat for handling the alpha/beta parameters, which are now also no longer fixed * Options panel: - glyph sizes of both CPs and RPs - splat opacity - splat parameters (alpha & beta) - color scale combo box currently does nothing
2016-01-16Added the Colormap component.Samuel Fadel
* 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.
2016-01-15VoronoiSplat & Scatterplot: splatting is now a separate component.Samuel Fadel
The change was due to future functionality requirements, this separation provides grater flexibility. As a nice side effect, the cropping bug when first rendering the splat is now gone.
2016-01-15QML: added components for handling selection modes in the future.Samuel Fadel
2016-01-13Subsamples/samples renamed to control points (CP) where possible.Samuel Fadel
2016-01-12main_view.qml: Fixed small typo.Samuel Fadel
2016-01-11Reordered scatterplot components and removed explicit z-order.Samuel Fadel
2016-01-11Main view is now a single projection.Samuel Fadel
* Smaller bar chart * Full projection is actually overlaid with the subsample projection so that the user can only move the subsample projection
2016-01-07Added a bar chart.Samuel Fadel
* HistoryGraph replaced by BarChart * HistoryGraph not removed from code, might be useful in the future
2016-01-06Restored width of main window.Samuel Fadel
2015-12-19Experimenting using VoronoiSplat as a texture.Samuel Fadel
2015-12-19New rendering (VoronoiSplat) -- incomplete.Samuel Fadel
* 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)
2015-10-22Added PLMP as an alternative technique to use; knn() is now exposed in the ↵Samuel Fadel
mp namespace.
2015-10-13Argument handling and file saving.Samuel Fadel
2015-09-29Inital history graph implementation and using linear scales where applicable.Samuel Fadel
- 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

2015-05-21Added (non-functional) file dialog for opening files.Samuel Fadel
2015-05-21Nearly complete implementation of interaction.Samuel Fadel
Interaction still does not work due to signals not being correctly emitted.

2015-05-21Updated UI.Samuel Fadel
- 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.
