Description

Methods

Public procedure LoadProgramFromBuffer(ABuf: PAnsiChar; ASourceType: TAd2dShaderSourceType; AProgramName: PAnsiChar; AShaderType: TAd2dShaderType); virtual; abstract;

Loads a shader program from a buffer.

Parameters
ASourceType
defines the type of the source code: binary or as sourcecode
AProgramName
specifies the name of the program in the shader sourcecode
AShaderType
defines the type of the shader program: a vertex or a fragment shader.
Public procedure Initialize; virtual; abstract;

Initializes the shader. This function should be called after the main surface is initialized.

Public procedure Finalize; virtual; abstract;

Finalizes the shader. This function should be called before the main surface has been finalized.

Public procedure Bind; virtual; abstract;

Activates the shader effect.

Public procedure Unbind; virtual; abstract;

Unbinds the shader effect.

Public function GetParameter(AName: PAnsiChar): Pointer; virtual; abstract;

Returns the pointer to the parameter with a specific name.

Public procedure SetParameter(AParam: Pointer; AValue: PSingle; ACount: integer); overload; virtual; abstract;

Sets a float parameter.

Public procedure SetParameter(AParam: Pointer; AValue: PInteger; ACount: integer); overload; virtual; abstract;

Sets a integer parameter.

Public procedure SetParameter(AParam: Pointer; AValue: TAd2dTexture); overload; virtual; abstract;

Sets a texture parameter.

Properties

Public property Loaded: boolean read GetLoaded;

Returns whether the shader is loaded.
