NAME

AG_DriverSDLGL —

agar SDL OpenGL driver

DESCRIPTION

The Agar sdlgl driver provides an interface to the Simple DirectMedia Layer (SDL) library, and renders GUI elements as OpenGL primitives and textures. Using AG_InitVideoSDL(3) as opposed to AG_InitGraphics(3), it is possible to attach Agar to an existing SDL display surface. If the SDL surface has the SDL_OPENGL flag set, Agar selects the sdlgl driver automatically.

INHERITANCE HIERARCHY

AG_Driver(3) -> AG_DriverSw(3) -> AG_DriverSDLGL.

EXAMPLES

AG_InitGraphics("sdlgl(width=640:height=480:depth=32)");
AG_InitGraphics("sdlgl(out=%08d.jpg:outFirst=10)");
AG_InitVideoSDL(screen, 0);

OPTIONS

stereo: Request a stereoscopic visual.
width: Width in pixels (or ‘auto’ for available desktop size).
height: Height in pixels (or ‘auto’).
depth: Depth in bits per pixel (or ‘auto’).
fpsMax: Limit GUI refresh rate in frames/second (default = 60fps).
out: Dump video frames to JPEG or PNG image files. The filename path may include a printf-style (with frame number as argument). For example, ‘%08d.jpg’ will output frames to 00000001.jpg, 00000002.jpg, etc.
outFirst: Override first frame number (default = 0).
outLast: Terminate application after # frames have been rendered.
bgColor: Solid background color (see AG_ColorFromString(3)). Default is "rgb(0,0,0)".
bgPopup: Show popup menu upon middle / right-button click in the background.
jpegQual: If exporting to JPEG, set quality factor (100% = best).
jpegDCT: If exporting to JPEG, specify DCT method ("islow" for slow but accurate integer method, "ifast" for fast but less accurate integer method, or "float" for floating point method).

HISTORY

The sdlgl driver first appeared in Agar 1.4.0.
