Soft-body dynamics is a field of computer graphics that focuses on visually realistic physical simulations of the motion and properties of deformable objects (or soft bodies). The applications are mostly in video games and films. Unlike in simulation of rigid bodies, the shape of soft bodies can change, meaning that the relative distance of two points on the object is not fixed. While the relative distances of points are not fixed, the body is expected to retain its shape to some degree (unlike a fluid). The scope of soft body dynamics is quite broad, including simulation of soft organic materials such as muscle, fat, hair and vegetation, as well as other deformable materials such as clothing and fabric. Generally, these methods only provide visually plausible emulations rather than accura

  • 연체동역학이란 연체 혹은 변형체의 운동과 특성을 시각적으로 사실적이게 구현하는 물리 엔진을 연구하는 컴퓨터 그래픽스 분야이다. 비디오 게임이나 영화를 만드는 데 주로 사용된다. 강체와는 달리 변형체는 힘을 가하면 모양이 변할 수 있다. 곧 변형체 안에서 두 점 사이의 거리는 일정하지 않다. 하지만 유체와는 달리 전체적인 형태는 유지한다. 실제로 대부분의 물체들이 강체가 아니라 변형체이기 때문에 연체동역학은 모발이나 식물 같은 유기체나, 옷감 등을 표현하는 등 매우 폭넓게 활용되고 있다. 일반적으로 물리학적으로 정확한 운동을 구현하는 것이 아닌 단지 시각적으로 그렇게 보이도록 구현하는 것 뿐이지만 유한 요소 시뮬레이션 등에서 일부 물리 법칙을 사용한다. 여러 물리엔진에서 연체동역학을 구현할 수 있는 소프트웨어를 제공한다.

  • Dinâmica de corpo macio (ou Dinâmica de corpo flexível, ou Mecânica de corpo flácido), do inglês Soft body dinamics, é a área da física que simula objetos flexíveis, isto é, objetos deformáveis, que pode ter suas posições mudadas. É usado em animações 3D, porém, ainda é novo no mercado de jogos. Há muitas forças que influenciam diretamente na aparência do objeto: fricção, gravidade, colisão, vento, etc. Usando a dinâmica de corpo flexível, é possível criar a ilusão de um objeto maleável, como roupas, cabelo, areia e água.
