draw_attributes

Warning: draw_attributes is deprecated.

First defines a geometry primitive by grouping a set of vertex attributes; specifying a first_vertex; a number of vertices (n_vertices) and specifying what kind of topology the vertices have via mode.

Then the function draws the given primitive geometry to the specified destination this using the graphics processing pipeline described by pipeline.

The list of Attribute<!-- -->s define the attributes of the vertices to be drawn, such as positions, colors and normals and the number of attributes is given as n_attributes.

This drawing api doesn't support high-level meta texture types such as Texture2DSliced so it is the user's responsibility to ensure that only low-level textures that can be directly sampled by a GPU such as Texture2D, TextureRectangle or Texture3D are associated with layers of the given pipeline.

<note>This api doesn't support any of the legacy global state options such as cogl_set_depth_test_enabled, cogl_set_backface_culling_enabled or cogl_program_use</note>

Parameters:

this	A destination Framebuffer
pipeline	A Pipeline state object
mode	The VerticesMode defining the topology of vertices
first_vertex	The vertex offset within the given attributes to draw from
n_vertices	The number of vertices to draw from the given attributes
attributes	An array of pointers to Attribute<-- -->s defining vertex geometry
n_attributes	The number of attributes in the attributes array.
