gl.CreateFBO
( [ table initialization ] ) -> userdata fbo
initialization table can contain:
attachment ::= luaTex or RBO or nil or { luaTex [, num target [, num level ] ] }
{
depth = attachment,
stencil = attachment,
color0 = attachment,
color1 = attachment,
color2 = attachment,
..
color15 = attachment,
drawbuffers = { GL_COLOR_ATTACHMENT0_EXT, GL_COLOR_ATTACHMENT3_EXT, ..}
}
gl.DeleteFBO (This doesn't delete the attached objects!)
( fbo ) -> nil
gl.IsValidFBO
( fbo [, number target ] ) -> boolean valid [, number status ]
gl.ActiveFBO
( fbo [, number target ] [, boolean identities ] , lua_function, arg1, arg2, ... ) -> nil
gl.UnsafeSetFBO (Binds a FBO like gl.ActiveFBO() does, but you have to unbind it yourself!)
( nil [, number target = GL_FRAMEBUFFER_EXT ] ) -> nil (Bind default screenbuffer)
( fbo [, number target = fbo.target ] ) -> nil
gl.RawBindFBO (Replaces UnsafeSetFBO starting from 104.0.1-1003-gb3e02a6 maintenance)
( nil [, number target = GL_FRAMEBUFFER_EXT ] [, number rawFboId = 0] ) -> nil (Bind default or specified via rawFboId numeric id of FBO)
( fbo [, number target = fbo.target ] ) -> number previouslyBoundRawFboId
gl.BlitFBO needs GLEW_EXT_framebuffer_blit
( int x0Src,y0Src,x1Src,y1Src,
int x0Dst,y0Dst,x1Dst,y1Dst
[, number mask = GL_COLOR_BUFFER_BIT [, number filter = GL_NEAREST ] ] ) -> nil
( fboSrc , int x0Src,y0Src,x1Src,y1Src,
fboDst , int x0Dst,y0Dst,x1Dst,y1Dst
[, number mask = GL_COLOR_BUFFER_BIT [, number filter = GL_NEAREST ] ] ) -> nil
attachment ::= luaTex or RBO or nil or { luaTex or RBO [, num target [, num level ]] }
write-only methods are:
fbo.depth = attachment
fbo.stencil = attachment
fbo.color0 = attachment
..
fbo.color15 = attachment
fbo.drawbuffers = { GL_COLOR_ATTACHMENT0_EXT, GL_COLOR_ATTACHMENT3_EXT, ..}
fbo.readbuffer = GL_COLOR_ATTACHMENT0_EXT
gl.CreateRBO
( int xsize, int ysize,
[ {
target = GL_RENDERBUFFER_EXT,
format = GL_RGBA,
[samples = number], any number here will result in creation of multisampled RBO (Added in 104.0.1-1015-g8e36ef2 maintenance)
} ]) -> userdata rbo
gl.DeleteRBO
( rbo ) -> nil
read-only methods are:
rbo.target = number
rbo.format = number
rbo.xsize = number
rbo.ysize = number
rbo.valid = boolean
rbo.samples = number will return globalRendering->msaaLevel for multisampled RBO or 0 otherwise (Added in 104.0.1-1015-g8e36ef2 maintenance)
