Detailed Description

Framebuffer class.

The Framebuffer class is a collection of framebuffers used for a frame rendering. It provide an interface to the named framebuffer attributes. It also allows to retrieve the index of the buffer to use it with mi_fb_put and mi_fb_get functions.

All strings are const char. Strings passsed in are copied, and need to be freed by the user. Strings passed out should be copied by the user, since they reference internal data.

virtual bool mi::shader_v3::Framebuffer::get (  const char *  buffer,
const char *  param,
const char *&  value
)  const [pure virtual]
 

get a string attribute for a framebuffer

Parameters:
buffer is the name of the framebuffer
param is the name of the attribute
value is the returned value of the attribute
Returns:
true if an attribute for the given framebuffer with the given name and type is found, false otherwise.

virtual bool mi::shader_v3::Framebuffer::get (  const char *  buffer,
const char *  param,
int &  value
)  const [pure virtual]
 

get an integer attribute for a framebuffer

Parameters:
buffer is the name of the framebuffer
param is the name of the attribute
value is the returned value of the attribute
Returns:
true if an attribute for the given framebuffer with the given name and type is found, false otherwise.

virtual bool mi::shader_v3::Framebuffer::get (  const char *  buffer,
const char *  param,
float &  value
)  const [pure virtual]
 

get a float attribute for a framebuffer

Parameters:
buffer is the name of the framebuffer
param is the name of the attribute
value is the returned value of the attribute
Returns:
true if an attribute for the given framebuffer with the given name and type is found, false otherwise.

virtual bool mi::shader_v3::Framebuffer::get (  const char *  buffer,
const char *  param,
bool &  value
)  const [pure virtual]
 

get a boolean attribute for a framebuffer

Parameters:
buffer is the name of the framebuffer
param is the name of the attribute
value is the returned value of the attribute
Returns:
true if an attribute for the given framebuffer with the given name and type is found, false otherwise.

virtual bool mi::shader_v3::Framebuffer::get_buffercount (  size_t &  buffercount  )  const [pure virtual]
 

get the count of buffers defined.

Parameters:
buffercount is the number of buffers.
Returns:
false on failure.

virtual bool mi::shader_v3::Framebuffer::get_buffername (  size_t  num,
const char *&  name
)  const [pure virtual]
 

get the name of buffer num. Note that num is not related to the index returned by get_index

Parameters:
num is the number of the buffer name to return, starting with 0.
name is the returned buffer name.
Returns:
false on failure.

virtual bool mi::shader_v3::Framebuffer::get_index (  const char *  buffer,
size_t &  index
)  const [pure virtual]
 

get an index of the framebuffer to be used in mi_fb_put and mi_fb_get functions.

Parameters:
buffer is the name of the framebuffer
index is the returned index
Returns:
true if an attribute for the given framebuffer with the given name and type is found, false otherwise.

virtual bool mi::shader_v3::Framebuffer::remove (  const char *  buffer  )  [pure virtual]

Returns:
true if the operation is successful, false otherwise.

virtual bool mi::shader_v3::Framebuffer::reset (   )  [pure virtual]
 

removes all named buffers. It is not legal to call this method during the rendering process.
