SMEAR v1.1.5

SMEAR 是一款 3D 動畫風(fēng)格化 Blender 插件，旨在創(chuàng)建和自定義拖尾幀，例如拉長的中間幀、多個中間幀和運動線。

使用說明

SMEAR 的控制面板應(yīng)出現(xiàn)在 Blender 的自定義 UI 面板中的 SMEAR 部分。

涂抹幀生成

此面板用于預(yù)處理動畫對象以創(chuàng)建拖尾幀，并控制此預(yù)處理的參數(shù)。“烘焙涂抹”按鈕使用選定的參數(shù)運行預(yù)處理。默認(rèn)參數(shù)在大多數(shù)情況下都是合適的。

參數(shù)：

如果您希望涂抹幀依賴于全身運動（例如，快速運動）而不是骨架，則可以對關(guān)節(jié)角色使用“忽略骨架”選項。

“修剪骨架”部分允許選擇將在預(yù)處理中忽略的骨骼。這些骨骼及其子骨骼的所有頂點都將受到其父骨骼的影響（參見論文第 3.2 節(jié)最后一段）

“時間平滑窗口”參數(shù)控制要考慮進行時間平滑的幀數(shù)，以避免時間噪聲效應(yīng)。默認(rèn)值為 N=2，通常可產(chǎn)生良好的效果。

“相機 POV”選項允許根據(jù)物體在相機空間中的運動（而不是在世界空間中的運動）計算模糊幀。目前僅適用于沒有骨架的簡單物體。

SMEAR is a 3D animation stylization Blender add-on, aimed at creation and customization of smear frames such as elongated in-betweens, multiple in-betweens and motion lines.

Instructions for use

The control panels for SMEAR should appear in the custom UI panels of Blender, in the section SMEAR.

Smear frame generation

This panel is used to pre-process animated objects to create smear frames, and control the parameters of this pre-process. The "Bake Smears" button runs the pre-process with the selected parameters. Default parameters will be appropiate in most use cases.

Parameters:

The “Ignore skeleton” option can be used for articulated characters if you want smear frames to depend on the full body movement (e.g., for fast motion) instead of the skeleton.

The "Prune Skeleton" section allows to select bones that will be ignored in the pre-processing. All vertices of these bones and their child will then be affected by their parent bones (see paper, section 3.2, last paragraph)

The “Temporal smoothing window” parameters control the number of frames to consider for temporal smoothing to avoid temporally noisy effects. Default is N=2 and gives generally good results.

The "Camera POV" option allows to compute smear frames depending on the motion of the object in camera space instead of in world space. Only available for simple objects with no skeleton for now.
