Typedef Documentation

◆ Cloth

typedef struct Cloth Cloth

This structure describes a cloth object against which the simulation can run.

The m and n members of this structure represent the assumed rectangular ordered grid for which the original paper is written. At some point they need to disappear and we need to determine out own connectivity of the mesh based on the actual edges in the mesh.

◆ ClothHairData

typedef struct ClothHairData ClothHairData

◆ ClothSolverResult

typedef struct ClothSolverResult ClothSolverResult

◆ ClothSpring

typedef struct ClothSpring ClothSpring

The definition of a spring.

◆ ClothVertex

typedef struct ClothVertex ClothVertex

The definition of a cloth vertex.

◆ ColliderContacts

typedef struct ColliderContacts ColliderContacts

◆ eClothVertexFlag

typedef enum eClothVertexFlag eClothVertexFlag
