Abstract base class for 3D shapes used for physics collision.
Description
Abstract base class for all 3D shapes, intended for use in physics. Performance: Primitive shapes, especially SphereShape3D, are fast to check collisions against. ConvexPolygonShape3D and HeightMapShape3D are slower, and ConcavePolygonShape3D is the slowest.
Properties
float custom_solver_bias = 0.0
float custom_solver_bias = 0.0The shape's custom solver bias. Defines how much bodies react to enforce contact separation when this shape is involved. When set to 0, the default value from ProjectSettings.physics/3d/solver/default_contact_bias is used.
float margin = 0.04
float margin = 0.04The collision margin for the shape. This is not used in Redot Physics. Collision margins allow collision detection to be more efficient by adding an extra shell around shapes. Collision algorithms are more expensive when objects overlap by more than their margin, so a higher value for margins is better for performance, at the cost of accuracy around edges as it makes them less sharp.
