Fbo /

Returns the width of the FBO in pixels.

Returns the height of the FBO in pixels.

Returns the size of the FBO in pixels.

Returns the bounding area of the FBO in pixels.

Returns the aspect ratio of the FBO.

Returns the Fbo::Format of this FBO.

Returns the Fbo::Format of this FBO.

Returns a reference to the color Texture2d of the FBO (at GL_COLOR_ATTACHMENT0 ). Resolves multisampling and renders mipmaps if necessary. Returns an empty Ref if there is no Texture2d attached at GL_COLOR_ATTACHMENT0 .

Returns a reference to the depth Texture2d of the FBO. Resolves multisampling and renders mipmaps if necessary. Returns an empty Ref if there is no Texture2d as a depth attachment.

Returns a Texture2dRef attached at attachment (such as GL_COLOR_ATTACHMENT0 ). Resolves multisampling and renders mipmaps if necessary. Returns NULL if a Texture2d is not bound at attachment .

Returns a TextureBaseRef attached at attachment (such as GL_COLOR_ATTACHMENT0 ). Resolves multisampling and renders mipmaps if necessary. Returns NULL if a Texture is not bound at attachment .

Binds the color texture associated with an Fbo to its target. Optionally binds to a multitexturing unit when textureUnit is non-zero. Optionally binds to a multitexturing unit when textureUnit is non-zero. attachment specifies which color buffer in the case of multiple attachments.

Unbinds the texture associated with an Fbo attachment.

Binds the Fbo as the currently active framebuffer, meaning it will receive the results of all subsequent rendering until it is unbound.

Resolves internal Multisample FBO to attached Textures. Only necessary when not using getColorTexture() or getTexture(), which resolve automatically.

Returns the ID of the framebuffer. For antialiased FBOs this is the ID of the output multisampled FBO.

For antialiased FBOs this returns the ID of the mirror FBO designed for multisampled writing. Returns 0 otherwise.

Returns the resolve FBO, which is the same value as getId() without multisampling.

Marks multisampling framebuffer and mipmaps as needing updates. Not generally necessary to call directly.

Copies to FBO dst from srcArea to dstArea using filter filter . mask allows specification of color ( GL_COLOR_BUFFER_BIT ) and/or depth( GL_DEPTH_BUFFER_BIT ). Calls glBlitFramebufferEXT() and is subject to its constraints and coordinate system.

Copies to the screen from Area srcArea to dstArea using filter filter . mask allows specification of color ( GL_COLOR_BUFFER_BIT ) and/or depth( GL_DEPTH_BUFFER_BIT ). Calls glBlitFramebufferEXT() and is subject to its constraints and coordinate system.

Copies from the screen from Area srcArea to dstArea using filter filter . mask allows specification of color ( GL_COLOR_BUFFER_BIT ) and/or depth( GL_DEPTH_BUFFER_BIT ). Calls glBlitFramebufferEXT() and is subject to its constraints and coordinate system.

Returns the debugging label associated with the Fbo .

Sets the debugging label associated with the Fbo . Calls glObjectLabel() when available.

Returns a copy of the pixels in attachment within area (cropped to the bounding rectangle of the attachment) as a Surface8u. attachment ignored on ES 2.

Returns a copy of the pixels in attachment within area (cropped to the bounding rectangle of the attachment) as a Surface32f. attachment ignored on ES 2.

Creates an FBO width pixels wide and height pixels high, using Fbo::Format format .

Creates an FBO width pixels wide and height pixels high, a color texture (with optional alpha channel), and optionally a depth buffer and stencil buffer.

Unbinds the Fbo as the currently active framebuffer, restoring the primary context as the target for all subsequent rendering.

Returns the maximum number of samples the graphics card is capable of using per pixel in MSAA for an Fbo .

Returns the maximum number of color attachments the graphics card is capable of using for an Fbo .

Helper function for readPixels8u() / readPixels32f() , returns read area.
