Constructor.
Definition at line 95 of file FramebufferObject.hpp.
| virtual const char* vl::FBORenderbufferAttachment::className | ( | ) | [inline, virtual] |
Returns the name of the class.
Reimplemented from vl::FBOAbstractAttachment.
Reimplemented in vl::FBOColorBufferAttachment, vl::FBODepthBufferAttachment, vl::FBOStencilBufferAttachment, and vl::FBODepthStencilBufferAttachment.
Definition at line 92 of file FramebufferObject.hpp.
| void FBORenderbufferAttachment::create | ( | ) |
Creates a renderbuffer object calling glGenRenderbuffers().
The identifier returned by glGenRenderbuffers() can be queried calling the handle() method.

| void vl::FBORenderbufferAttachment::setHandle | ( | GLuint | handle ) | [inline] |
Sets the handle for this attachment, the handle must have been created by glGenRenderbuffers().
Normally you don't need to call this. See also: create(), handle().

| GLuint vl::FBORenderbufferAttachment::handle | ( | ) | const [inline] |
Returns the handle obtained by create() using glGenRenderbuffers()

| void FBORenderbufferAttachment::initStorage | ( | int | w, |
| int | h, | ||
| int | samples | ||
| ) |
Initializes the storage of the renderbuffer with the given sample count and dimensions.
This method does nothing if the the width, height and sample count has not changed since last time it was called. Note that the renderbuffer storage type is defined by the setType() method of FBOColorBufferAttachment, FBODepthBufferAttachment, FBOStencilBufferAttachment, FBODepthStencilBufferAttachment. See also setSamples().

| void vl::FBORenderbufferAttachment::setWidth | ( | int | w ) | [inline] |
The width of the renderbuffer storage to be allocated.
If 'w' is set to 0 the renderbuffer storage allocation will use the dimensions of the next FBORenderTarget bound.
Definition at line 152 of file FramebufferObject.hpp.
| void vl::FBORenderbufferAttachment::setHeight | ( | int | h ) | [inline] |
The height of the renderbuffer storage to be allocated.
If 'h' is set to 0 the renderbuffer storage allocation will use the dimensions of the next FBORenderTarget bound.

| void vl::FBORenderbufferAttachment::setSamples | ( | int | samples ) | [inline] |
Sets the number of samples to be specified when allocating the renderbuffer's storage.

| bool vl::FBORenderbufferAttachment::renderbufferStorageReady | ( | ) | const [inline] |
Returns false if the renderbuffer storage needs to be created or reallocated due to a change of the sample count, renderbuffer type or dimension.
