SG_PROGRAM(3)

NAME
SG_Program - Agar-SG vertex/fragment program

SYNOPSIS

    #include <agar/core.h>
    #include <agar/sg.h>

DESCRIPTION
The SG_Program object represents a generic vertex or pixel shader program. Applications will rarely use the SG_Program interface directly, since programs in specific languages will use subclasses such as SG_CgProgram(3).

INHERITANCE HIERARCHY
AG_Object(3) -> SG_Program.

INTERNAL WIDGET API
The following functions are used by SG_View(3) (or derived widgets), when rendering a scene.

int SG_ProgramInstall(SG_Program *prog, SG_View *view)

void SG_ProgramDeinstall(SG_Program *prog, SG_View *view)

void SG_ProgramBind(SG_Program *prog, SG_View *view)

void SG_ProgramUnbind(SG_Program *prog, SG_View *view)

The SG_ProgramInstall() function installs the program defined in prog. This generally involves verifying, compiling and uploading the code to the hardware. The program is not effective until bound.

SG_ProgramDeinstall() deinstalls / releases the program defined in prog.

SG_ProgramBind() binds the program defined in prog to the current scene.

SG_ProgramUnbind() unbinds the program defined in prog from the current scene.
