Hi Sachin,<br><br>I have summarized current status of clutk porting below, and if you have time, we can check the left issues together as we discussed in the conf-call yesterday. I think the issue marked with yellow has highest priority currently.<br>
<br>Branch:<br>+ <a href="https://code.launchpad.net/~jammy-zhou/clutk/gles2-shaders.hacky">https://code.launchpad.net/~jammy-zhou/clutk/gles2-shaders.hacky</a><br><br>Issues Fixed:<br>+ Normalize clutter vetex positions to adapt to the vertex shader<br>
+ Use GL_TRIANGLE_FAN to implement original used GL_QUADS primitive, which is not supported by gles2<br>+ Comment out cogl_flush() call in some functions (such as ctk_effect_blur_paint) to make sure following gles2 rendering can be shown<br>
+ Fix render to cached texture problems<br><span style=""><span style="background-color: rgb(0, 0, 0);"></span></span><br>Issues Left:<br>+ run test-clutk, there is crash at &quot;/Effect/Animation/Animation&quot; test suite. This issue has already been reported by Alexandros, see 
<a href="https://bugs.launchpad.net/clutk/+bug/614415" target="_blank">https://bugs.launchpad.net/clutk/+bug/614415</a>, and it should be an upstream problem.<br>+ when run &quot;test-clutk-perf 0 10 125 5 single animated blur 0.3.2 GMA950 2.1 1 10&quot;, crash happens with following error message. The error happens when call glBindFramebuffer (GL_FRAMEBUFFER, 0).<br>
Clutk-WARNING **: [CheckGLError] GL_INVALID_OPERATION error in File ./ctk-render-target.c at line: 581<br><span style="background-color: rgb(255, 255, 255);">+ </span><span style="background-color: rgb(255, 255, 51); color: rgb(0, 0, 0);">the actor painting (i.e, &quot;paint_func(actor);&quot; in ctk_effect_blur_paint) seems independent from other gles2 rendering, and it is not rendered into cached texture for later display. This means that we cannot add special effects to the actor.</span><br>
