Peek3D 1.3.1

Fixed

• Animated models are framed on the poses their clips actually reach, instead of a fixed margin around the rest pose.
• The animation timeline stops updating while its window is covered or hidden, not only when minimized.

Peek3D 1.3

Added

• Scene ▸ Play/Pause (Space) and Step Backward/Forward (← →): control the animation from the keyboard without focusing the timeline.

Peek3D 1.2.1

Fixed

• Lower CPU use: the axis gizmo draws at 30 fps, and minimized or hidden
  windows stop redrawing.
• Skinned and morphing models are framed with room for their animation
  instead of touching the window edges.
• VoiceOver reads the animation menu as "Choose animation" instead of the
  icon's name.

Peek3D 1.2

Added

• Animation timeline: drag (or click) the bar to jump to any instant, for
  glTF and FBX. Playing resumes from where you left it. Keyboard: focus the
  bar and use ← →; VoiceOver: swipe up/down, the position is spoken in seconds.
• FBX skinning and blend shapes: skeletal meshes now deform with their
  animation instead of staying in the bind pose, and animated blend-shape
  weights play back.
• glTF files with Draco-compressed geometry (KHR_draco_mesh_compression)
  now open; a damaged Draco stream shows an error instead of crashing.
• KTX2/BasisU textures (KHR_texture_basisu) are covered by the test suite:
  they were already decoded by GLTFKit2 and now have fixtures that prove it.

Fixed

• A KHR_texture_basisu texture naming a missing image crashed the app
  instead of showing an error.

Peek3D 1.1

Bug-fix release from a full debugging pass of the app.

Fixed

• Malformed glTF/GLB files (broken buffers, accessors, skins, animation
  ranges) could crash or hang the app; they now show an error. Empty or
  non-3D files say so instead of showing a blank window.
• Absurdly deep node hierarchies no longer crash the app.
• External files: a .gltf with a separate .bin, or an .obj with its .mtl
  and textures, now offers "Grant folder access" like FBX did; textures
  that don't exist are no longer blamed on folder permissions.
• Untranslated messages, plurals (Russian, Arabic…), numbers, sizes and
  durations now follow the app language and region.
• VoiceOver: labeled toolbar, viewport, gizmo and timeline; load results
  and banners are announced. The six gizmo views are in Scene ▸ Views
  (⌃⌘1…6); ⌘+ / ⌘− zoom.
• Readable overlays and banners over light models (WCAG AA), Esc closes
  banners; Reduce Motion, Reduce Transparency and Increase Contrast are
  honored.
• ⌘T from Settings no longer tabs a Welcome screen into Settings.
• FBX: correct vertex and mesh counts; instanced meshes load several times
  faster with a fraction of the memory.
• Smoother playback: the timeline no longer redraws the whole window 60
  times a second.
• Error and folder-access notices no longer cover the model info panel.
• Smaller fixes: duplicate Fullscreen command removed, zoom limits, Welcome
  fits 900 pt screens, file type names localized in Finder.
