Description

Fields

Public Verts: PArray_Vertex3ds;

Verts i Faces read-only from outside

Public Faces: PArray_Face3ds;
 

Methods

Public constructor Create(const AName: string; AScene: TScene3ds; Stream: TStream; ObjectEndPos: Int64); override;

constructor TTrimesh3ds ma za zadanie odczytac caly chunk CHUNK_OBJBLOCK. Zaklada on ze przed chwila ze strumienia odczytano chunk header o id = CHUNK_OBJBLOCK i jakims len z ktorego wynika ze gdy Stream.Position >= ObjectEndPos to juz jestesmy za tym obiekte,. Potem odczytano AName. (czyli teraz mozna przystapic do odczytywania subchunkow).

Public destructor Destroy; override;
 

Properties

Public property HasTexCoords: boolean read FHasTexCoords;

czy Verts mialy zapisane w pliku TexCoords ?

Public property VertsCount: Word read FVertsCount;

pamietaj ze przypadek VertsCount = FacesCount = 0 jest mozliwy, np. 0155.3ds.

Public property FacesCount: Word read FFacesCount;
 
Public property BoundingBox: TBox3d read FBoundingBox;
