22 -- Add NumberOfTextures() and TextureName() methods
25 class TextureEnv from Graphic3d
27 inherits TextureRoot from Graphic3d
30 ---Purpose: This class provides environment texture usable only in Visual3d_ContextView
33 NameOfTextureEnv from Graphic3d,
34 StructureManager from Graphic3d
37 OutOfRange from Standard
40 Create(SM : StructureManager from Graphic3d;
41 aFileName : CString from Standard)
42 returns mutable TextureEnv from Graphic3d;
43 ---Purpose: Creates an environment texture from a file
45 Create(SM : StructureManager from Graphic3d;
46 aName: NameOfTextureEnv from Graphic3d)
47 returns mutable TextureEnv from Graphic3d;
48 ---Purpose: Creates an environment texture from a predefined texture name set.
50 Name(me) returns NameOfTextureEnv from Graphic3d;
52 -- Returns the name of the predefined textures or NOT_ENV_UNKNOWN
53 -- when the name is given as a filename.
56 NumberOfTextures(myclass) returns Integer from Standard;
58 -- Returns the number of predefined textures.
61 TextureName(myclass; aRank: Integer from Standard)
62 returns CString from Standard
63 raises OutOfRange from Standard;
65 -- Returns the name of the predefined texture of rank <aRank>
66 ---Trigger: when <aRank> is < 1 or > NumberOfTextures.
