* a "gl_Position" describing the (x,y,z) position for each vertex.

|

* The Vertex Buffer API is designed to be a fairly raw mechanism for
|
||||
* developers to be able to submit geometry to Cogl in a format that can be
|
||||
* directly consumed by an OpenGL driver and with awareness of the specific
|
||||
* hardware being used then costly format conversion can also be avoided.
|
||||
* directly consumed by an OpenGL driver and mapped into your GPU for fast
|
||||
* re-use. It is designed to avoid repeated validation of the attributes by the
|
||||
* driver; to minimize transport costs (considering indirect GLX use-cases)
|
||||
* and to potentially avoid repeated format conversions when attributes are
|
||||
* supplied in a format that is not natively supported by the GPU.
|
||||
*
|
||||
* They are designed to work on top of buffer objects and developers should
|
||||
* understand that attribute buffers are not that cheap to create but once they
|
||||
* have been submitted they can be stored in GPU addressable memory and can
|
||||
* be quickly reused.
|
||||
* Although this API does allow you to modify attributes after they have been
|
||||
* submitted to the GPU you should be aware that modification is not that
|
||||
* cheap, since it implies validating the new data and potentially the
|
||||
* OpenGL driver will need to reformat it for the GPU.
|
||||
*
|
||||
* Although this API does allow you to modify attribute buffers after they have
|
||||
* been submitted to the GPU you must note that modification is also not that
|
||||
* cheap, so if at all possible think of tricks that let you reuse a static
|
||||
* buffer. To help with this, it is possible to enable and disable individual
|
||||
* attributes cheaply.
|
||||
*
|
||||
* Take for example attributes representing an elipse. If you were to submit
|
||||
* color attributes, texture coordinates and normals, then you would be able
|
||||
* to draw an elipses in the following different ways without modifying
|
||||
* the vertex buffer, only by changing your source material.

* <itemizedlist>
|

|
||||
* <listitem>Textured elipse</listitem>
|
||||
* <listitem>Smoothly lit textured elipse blended with the color.</listitem>
|
||||
* </itemizedlist>
|
||||
*
|
||||
* Another trick that can be used is submitting highly detailed vertices and
|
||||
* then using cogl_vertex_buffer_draw_range_elements to sample sub-sets of
|
||||
* the geometry or lower resolution geometry out from a fixed buffer.
|
||||
*
|
||||
* The API doesn't currently give you any control over the actual OpenGL buffer
|
||||
* objects that are created, but you can expect that when you first submit
|
||||
* your attributes they start off in one or more GL_STATIC_DRAW buffers.
|
||||
* If you then update some of your attributes; then these attributes will
|
||||
* normally be moved into new GL_DYNAMIC_DRAW draw buffers.
|
||||
* If at all possible think of tricks that let you re-use static attributes,
|
||||
* and if you do need to repeatedly update attributes (e.g. for some kind of
|
||||
* morphing geometry) then only update and re-submit the specific attributes
