Shader Development Studio Problem

Mykhailo Kromarenko
Note: This was originally posted on 12th May 2011 at http://forums.arm.com

Hello,
Recently I decided to try out Mali Developer Tools, which look very promising.

Unfortunately I have a problem with Shader Development Studio.
When trying to make SimpleTest Project (from the User Guide) while rendering the shader effect
the Shader Preview shows a triangle instead of a square shown in the Guide.
In general, it is not surprising, since the option VERTICES in Shader Attributes View has by default  three
vertices:
-1.0 -1.0,0.0,1.0,
1.0 -1.0,0.0,1.0,
1.0,1.0,0.0,1.0,

The problem however is that there is no possibility to add additional vertices
(when choosing the option USER_DEFINED). You can only change the three given.
Changing the geometry in Shader Control View do not bring any effect, always showing three vertices.
Even when using a Shader Examples from Mali GPU Shader Library shaders are applied to that triangle.
The shaders themselves are working (changing color, texturing, etc).

Plugin has been tested on the following configurations:
Eclipse 3.6.2
  • GeForce 9600M GT Windows 7 64bit
  • GeForce GTS 250 Windows 7 32bit

All necessary OpenGL extensions are present, Emulator and Offline Shader Compiler are installed and work.

    Yes, in general the version of windows should not play a special role here, but I was able to try the plugin
    on the third computer with windows 7 already (albeit with similar characteristics that were given above)
    on a clean eclipse installation. The problem is the same.

    About adding additional vertices, I just wanted to add a fourth vertex to the three present, in order to
    turn it into a square, but in principle, several different meshes should be sufficient for shader testing.
    Speaking about the three vertices, I proceed from the fact that VERTICES variable represent 3 homogeneous vertices
    (one in each row). Since I am not sure, here is a picture
     
    In error log I found two errors related to the plugin:

    The first one happened rarely apparently at the opening of a (closed) project:

    Message: Unhandled event loop exception
