 d) I wanted to load binary shader using OpenGL ES 2.0.
So does it supports binary shaders?.

Cogl doesn't currently binary shaders.

 e) I wanted to load 3d objects and provide data to cogl_vertex_
 buffer_draw().So can we some how connect this 3D object with actor?.

Once you have the data in a CoglVertexBuffer you can render it as part
of an actor by implementing the paint signal. This is exactly what the
ClutterPLY library does.

Hi Emmanuele,
  
Is any 2D UI tool is there using clutter.
I am trying to figure out capability of Clutter
for UI tools. Thanks for your reply. 
Regards,
RK.

 a)   Is clutter can load collada file format

no, it can't.

  or we can use collada dom parser inside clutter and pass data to 
 
 Clutter API. 

this is probably the safest approach; we have an external library
loading a scene from PLY, I guess you can look at how it's implemented
to write a Collada loader:

  http://git.clutter-project.org/cgit.cgi?url=toys/tree/clutter-ply

 b)   Is Clutter has a built in API for Basic primitive like
 Cylinder , Cone ,Sphere

no. Clutter's primitives set are 2D, not 3D.

 c)   Is any 3D HMI tool is available using Clutter

HMI? you mean a 3D design tool? no.

 d)   Clutter support is there or not for binary format

binary format of what? you mean compressed textures? no, though it's
planned for 1.4.

e) Can be load 3d modeling data(like collada or .3ds) as a
 actor so we can easily identify mouse click on actor.

again, Clutter can use a simple external library to load PLY files;
nothing prevents you from writing a Collada or 3D Studio Max loader.

ciao,
 Emmanuele.
