BlobMesh Compound Object

The BlobMesh compound object creates a set of spheres from geometry or particles, and connects the spheres together as if they were made of a soft, liquid substance. When the spheres move within a certain distance of one another, they connect together. When they move apart, they take on a spherical form again.

In the 3D industry, the general term for spheres that operate in this way is metaballs. The BlobMesh compound object generates metaballs based on specified objects in the scene, and the metaballs, in turn, form a mesh result called a blobmesh. A blobmesh is ideal for simulating thick liquids and soft substances that move and flow when animated.

When you associate an object or particle system with the BlobMesh compound object, the metaballs are placed and sized differently depending on the object used to generate them:

• For geometry and shapes, a metaball is placed at each vertex, and the size of each metaball is determined by the size of the original BlobMesh object. Soft selection can be used to vary the sizes of the metaballs.

• For particles, a metaball is placed at each particle, and the size of each metaball is determined by the size of the particle on which it’s based.

• For helpers, a metaball is placed at the pivot point, and the size of the metaball is determined by the original BlobMesh object.

Note: You can apply motion blur to a BlobMesh object to enhance the effects of motion in renderings. For particle systems other than Particle Flow, use Image motion blur. For Particle Flow particle systems and all other types of objects including geometry, shapes, and helpers, use Object motion blur.

Tension張力─數值越大則部線越鬆弛，部線鬆弛也就是佈線越平均，metaball 的體積也會增大。
Evaluation Coarseness計算粗糙度
Relative Coarseness相對粗糙度
Large Data Optimization大型數據優化─也就是當metaball過於龐大時進行優化，例如用於粒子系統之時。
