%description
Surf Ice renders neuroimaging surface meshes with statistical overlays,
fibre tractography and connectome node and edge graphs, with ambient
occlusion, matcap shading, clipping planes and transparency. It reads
GIfTI, FreeSurfer, MZ3, OBJ, PLY, STL, VTK, CIFTI and OpenCTM meshes,
TrackVis, TRX and VTK streamlines and BrainNet node/edge files, and can
turn a NIfTI volume into a mesh. Rendering can be scripted in Python
(import gl) for batch figure production. It is the surface companion to
MRIcroGL.

Architecture-independent files for Surf Ice: GLSL shaders, colour lookup
tables, matcap textures, font atlases, example Python scripts, and sample
meshes (MNI152 2009 cortex, BrainNet Viewer meshes and node/edge files,
and an fMRI motor activation).

# Render the shipped MNI152 cortex, then the same view with the shipped
# motor activation, through the embedded Python from the installed tree. A
# PNG exists only if libpython was found and loaded and the gl module ran;
# the comparisons fail if the mesh did not load or the overlay was not drawn.
# Preferences for a headless run: Xvfb's llvmpipe offers no multisampled GLX
# configs, so the default MultiSample=1 makes Lazarus raise "Could not find
# FB config" in a modal dialog. On Mesa, Surf Ice drops to "Poor" quality,
# where savebmpxy reads back whatever the window last painted (stale under
# a script); "Better" (MesaWarned=1, RenderQuality=1) renders each capture
# into a framebuffer object. The -S script also starts before the GL control
# is realised, hence the first wait.

* Fri Oct 16 2026 Morgan Hough <morgan.hough@gmail.com> - 1.0.20260427-1
- Initial package: master 69f80b6, Qt 6 widgetset, Python scripting through
  the system libpython loaded at run time.
- Prebuilt libpython, zlib objects and Windows runtimes removed; the AICHA
  atlas (non-commercial), the Fubax matcap and the Ubuntu font atlas
  removed.
- %%check renders a shipped mesh and overlay through a Python script under
  Xvfb with llvmpipe and checks the PNG.
