Public procedure FaceVertex(x, y, z: Single); overload;

Adds and interpretates a vertex at the given position.

Public procedure FaceVertex(ARef: Pointer); overload;

Adds and interpretates a vertex at the given position. the position.

Parameters
ARef
Pointer to a sequence of three Single values in xyz format, which represent
Public procedure FaceEnd;

Resets the values for vertex interpretation.

Properties

Public property TotalArea: Single read FTotalArea;

The total surface area of the emitter.

Public property UseFaceMatrix: Boolean read FUseFaceMatrix write FUseFaceMatrix;

If true, the rotation matrix of the face is used to rotate the velocity vector. For example the velocity vector (0, 1, 0) would always be orthogonal to the face.
