Ghi chú
"Va Đập vào Bản Thân" is working only if you have activated "Dùng Cạnh".
When enabled, allows you to control how Blender will prevent the soft body from intersecting with itself. Every vertex is surrounded with an elastic virtual ball. Vertices may not penetrate the balls of other vertices. If you want a good result you may have to adjust the size of these balls. Normally it works pretty well with the default options.
- Phương Pháp Tính Toán (Calculation Type)
- Thủ Công (Manual):
The "Kích Thước Hình Cầu" directly sets the ball size.
- Trung Bình/Hóa:
The average length of all edges attached to the vertex is calculated and then multiplied with the Ball Size setting. Works well with evenly distributed vertices.
- Tối Thiểu/Tối Đa (Minimal/Maximal):
The ball size is as large as the smallest/largest spring length of the vertex multiplied with the Ball Size.
- Trung Bình Tối Thiểu Tối Đa (Average Min Max):
Size = ((Min + Max)/2) × "Kích Thước Hình Cầu".
- Kích Thước Hình Cầu (Ball Size)
Fraction of the length of attached edges. The edge length is computed based on the chosen algorithm. This setting is the factor that is multiplied by the spring length. It is a spherical distance (radius) within which, if another vertex of the same mesh enters, the vertex starts to deflect in order to avoid a self-collision.
Set this value to the fractional distance between vertices that you want them to have their own "space". Too high of a value will include too many vertices at all times and slow down the calculation. Too low of a level will let other vertices get too close and thus possibly intersect because there will not be enough time to slow them down.
- Độ Cứng (Stiffness)
How elastic that ball of personal space is. A high stiffness means that the vertex reacts immediately to another vertex enters their space.
- Giảm Chấn (Dampening)
How the vertex reacts. A low value just slows down the vertex as it gets too close. A high value repulses it.
Ghi chú
Collisions with other objects are set in the (other) Collision panel. To collide with another object they have to share at least one common layer.
