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.

    Hi all,

    I've just been trying to reproduce this issue with a Windows 7 machine, but still can't seem to make the bug appear :( For reference, the steps I took were:

    1. Open Eclipse
    2. Create a new 'General' project
    3. Add a new vertex and fragment shader
    4. Add a shader configuration and add the appropriate shaders. Save the shader configuration.
    5. Select the 'New Effect' in the Shader Control view
    6. I see that the default geometry is "PLANE"
    7. Set up the attributes ('coord' to 'VERTICES') and ('camera' to 'CAMERA_MATRIX')
    8. Select the built-in renderer from "Manage Renderers"
    9. Render a single frame

    I see at this point a coloured square. I can then select a new geometry (say, "SPHERE") and the geometry changes for me. Am I doing anything different to you? My platform is Eclipse 3.7, OpenGL ES 2.0 Emulator 1.3.0 M1, Windows 7 Professional and an NVIDIA GeForce 210.

    Hi,

    I am also facing this problem, is there any workaround present to fix the geometry selection problem?

    Configs:
    1) Win 7 Pro 32 bit
    2) Win 7 Ultimate 64 bit

    Both use the most current Eclipse version.
    -> using Android SDK
    -> using Android Projects

    Regards,

    Are you following the same procedure I outlined in my post above? I can't reproduce the issue on any platform I've tried, but I wonder if I might be doing something different to you?

    Yes, to the point. Tried it again a few moments ago to be sure.

    The difference to your configuration seems to be the graphics card (ATI Radeon HD 5700) at first glance.

    I wonder if a fresh and minimal installation of Eclipse will make a difference. Will try this next.

    With a fresh Eclipse installation (Indigo) and a fresh workspace these Exceptions can be taken from the log:

    Maybe it helps to find a solution to the problem.

    The fact that I did a fresh install and it still does not work is quite odd. For me it looks like an issue indirectly related to Eclipse may be at hand. Like Java installation JRE/SDK maybe.
    @rdc: Here some questions that might help to get the issue pinned.

    1) Where did you install the ARM files? Default folder?
    2) Any special changes to the system? I am thinking of tinkering with the PATH variable and permissions maybe.
