glint_engine 0.1.2

A pure-Dart 3D engine on Flutter GPU: glTF models, PBR + HDRI lighting, animation, tap picking, anchored widgets, and a real-time game loop.

0.1.2

• Explicitly declare supported platforms (iOS, macOS, Android) in pubspec.yaml. Pana's automatic detection reports 0/6 platforms for any package depending on flutter_gpu, because its dart:nativewrappers import chain isn't statically resolvable — declaring platforms overrides that detection instead of waiting on it.

0.1.1

• Rewrite the README: pub.dev badges, quick-nav links, and an FAQ covering platform support and the flutter_scene comparison directly.

0.1.0

The first complete Glint release: a pure-Dart 3D engine on Flutter GPU.

• Render binary glTF 2.0 models from assets or network: scene hierarchy, node transforms, generated or authored normals, 16/32-bit indices.
• Per-primitive material batches with embedded base-color textures (decoded with a 1K cap for mobile memory), factors, metallic, roughness.
• GGX metallic-roughness PBR with directional lighting, HDRI image-based lighting (built-in Radiance .hdr decoder and CPU prefiltering), and distance fog.
• glTF node animation playback: translation/rotation/scale channels, LINEAR/STEP sampling, quaternion slerp, automatic looping.
• Scene3D declarative API: scenes route to the GPU renderer, materials update live through setState, hot reload rebuilds shaders.
• Tap picking via CPU raycasting, and Label3D — Flutter widgets anchored to model surfaces with fade/hide occlusion policies.
• Scroll-aware gesture routing so scenes cooperate with scrollable pages.
• GlintGameView game loop: unlimited model instances with per-node transforms, free look-at camera, translucent blob-shadow pass, per-frame frustum culling, and an allocation-free draw loop (validated at 60 fps on iPhone with ~160 draws per frame).
• Live FPS/frame-time/draw/triangle diagnostics and typed, actionable errors for every asset failure.
• Four runnable examples: an endless-runner game, a product configurator, a minimal viewer, and an anchored-labels demo.

0.0.1

• Establish the Glint package and declarative Scene3D(scene:) API.
• Add the pure-Dart bootstrap renderer, orbit gestures, and overlay demo.
• Add indexed, depth-tested, textured flutter_gpu rendering.
• Add PNG/JPEG asset decoding with actionable texture errors.
