-- File: Graphic3d_Texture2Dplane.cdl
-- Created: Mon Jul 28 10:44:24 1997
-- Author: Pierre CHALAMET
-- <pct@sgi93>
-- Modified : GG IMP280200
-- Add Plane(),ScaleT(),ScaleS() methods
---Copyright: Matra Datavision 1997
class Texture2Dplane from Graphic3d
inherits Texture2D from Graphic3d
---Purpose: This class allows the management of a 2D texture defined from a plane equation
-- Use the SetXXX() methods for positioning the texture as you want.

NameOfTexturePlane from Graphic3d,

is
Create(SM : StructureManager from Graphic3d;
FileName : CString from Standard) returns mutable Texture2Dplane from Graphic3d;
---Purpose: Creates a texture from a file
Create(SM : StructureManager from Graphic3d;
NOT : NameOfTexture2D from Graphic3d) returns mutable Texture2Dplane from Graphic3d;
---Purpose: Creates a texture from a predefined texture name set.
SetPlaneS(me : mutable; A,B,C,D : ShortReal from Standard);
---Purpose: Defines the texture projection plane for texture coordinate S
-- default is <1.0, 0.0, 0.0, 0.0>
SetPlaneT(me : mutable; A,B,C,D : ShortReal from Standard);
---Purpose: Defines the texture projection plane for texture coordinate T
-- default is <0.0, 1.0, 0.0, 0.0>
SetPlane(me : mutable; APlane : NameOfTexturePlane from Graphic3d);
---Purpose: Defines the texture projection plane for both S and T texture coordinate
-- default is NOTP_XY meaning:
-- <1.0, 0.0, 0.0, 0.0> for S
-- and <0.0, 1.0, 0.0, 0.0> for T
SetScaleS(me : mutable; val : ShortReal from Standard);
---Purpose: Defines the texture scale for the S texture coordinate
-- much easier than recomputing the S plane equation
-- but the result is the same
-- default to 1.0
SetScaleT(me : mutable; val : ShortReal from Standard);
---Purpose: Defines the texture scale for the T texture coordinate
-- much easier than recompution the T plane equation
-- but the result is the same
-- default to 1.0
SetTranslateS(me : mutable; val : ShortReal from Standard);
---Purpose: Defines the texture translation for the S texture coordinate
-- you can obtain the same effect by modifying the S plane
-- equation but its not easier.
-- default to 0.0
SetTranslateT(me : mutable; val : ShortReal from Standard);
---Purpose: Defines the texture translation for the T texture coordinate
-- you can obtain the same effect by modifying the T plane
-- equation but its not easier.
-- default to 0.0
SetRotation(me : mutable; val : ShortReal from Standard);
---Purpose: Sets the rotation angle of the whole texture.
-- the same result might be achieved by recomputing the
-- S and T plane equation but it's not the easiest way...
-- the angle is expressed in degres
-- default is 0.0
--
-- inquire methods
--
Plane(me) returns NameOfTexturePlane from Graphic3d;
---Purpose: Returns the current texture plane name or NOTP_UNKNOWN
-- when the plane is user defined.
PlaneS(me; A,B,C,D : out ShortReal from Standard);
---Purpose: Returns the current texture plane S equation
PlaneT(me; A,B,C,D : out ShortReal from Standard);
---Purpose: Returns the current texture plane T equation
TranslateS(me; val : out ShortReal from Standard);
---Purpose: Returns the current texture S translation value
TranslateT(me; val : out ShortReal from Standard);
---Purpose: Returns the current texture T translation value
ScaleS(me; val : out ShortReal from Standard);
---Purpose: Returns the current texture S scale value
ScaleT(me; val : out ShortReal from Standard);
---Purpose: Returns the current texture T scale value
Rotation(me; val : out ShortReal from Standard);
---Purpose: Returns the current texture rotation angle
