What's Changed

User-facing changes:

• Several improvements to the emscripten/browser/mobile device version:
  • fixed a bug that prevented Samplin' Safari from running properly on iPhone in the browser (previously had an all-black screen)
  • zooming, via a pinch gesture, now works on touchscreen-enabled devices (previously zoom only worked via scroll if a mouse/touchpad was connected)
  • on small screens, automatically chooses a mobile-friendly portrait or landscape layout based on screen orientation
• switched from GL_LINES-based grids, to beautifully antialiased shader-based grids
• switched from GL_POINTS to instanced billboard-based point rendering
  • points now have a consistent world-space size (instead of having a fixed screen-space size)
• subtle 3D shading on points using simple hardcoded SH lighting
• keyboard shortcut documentation in about/help screen
• improved handling on FPS idling
• fixed a bug where points and grid were being drawn at wrong depth in the 2D projections view, making zooming not work

Behind-the-scenes changes:

• updating to latest fmt and galois++ libraries
• udating hello_imgui to latest version, linux builds now default to using system-installed glfw packages
• enforcing webGL2.0 in emscripten, allowing GLSL #version 300 es and simplifying compatibility with #version 330 core
• added support for instanced drawing and attribute offsets to Shader class
• assets are now re-copied during build if there are any changes to e.g. shaders, instead of requiring a manual cmake reconfigure

Full Changelog: v2.0.0...v2.1.0

v2.0.0

The next major release of Samplin' Safari, with many changes and new features!

What's Changed

• Entirely rewritten GUI based on Hello ImGui/Dear ImGui. Allows for docking windows, menu bars, and more.
• Samplin' Safari can now run entirely in your browser thanks to emscripten! Check it out here.
• You can now save the points as EPS, SVG, and plain text CSV files (available from the File menu)
• CSV files containing one point per line can now be loaded for viewing
• In addition to the bounding box, fine, and coarse grids, you can now show a custom grid where the number of subdivisions can be specified per dimension. This can be particularly useful to visually confirm a point set is stratified over all elementary intervals.
• Added several new samplers:
  • Ahmed's (0,2) xi-sequence and Gray code-based (0,m,2) nets.
  • Paulin's Cascaded Sobol'
  • Helmer's stochastic Sobol' and Faure sequences
  • Sudoku and correlated Sudoku (which are nested multi-jittered/orthogonal array samplers)
