    [GLSL  on ATIHD4800]No matching overloaded function found texture3D


      Hello I just update my driver and attempt to run a simple volume rendering GLSL shader on my ATI using ARB_fragmentshader

      However I get an incredible error: the function texture3D is apparently not define?!!! I have the same error on my HTPC with a HD4xxxx chipset...

      My shader :

      uniform sampler3D  tex3D;
      uniform sampler1D  tf;//transfert function

      void main(){
      vec4 col= texture3D(tex3D, gl_TexCoord[0]);
      gl_FragColor= texture1D(tf, col.a);


      My error:

      FRAGMENT glCompileShader "" FAILED
      FRAGMENT Shader "" infolog:
      Fragment shader failed to compile with the following errors:
      ERROR: 0:7: error(#202) No matching overloaded function found texture3D
      ERROR: 0:7: error(#160) Cannot convert from 'const float' to 'highp 4-component
      vector of float'
      ERROR: error(#273) 2 compilation errors.  No code generated

      glLinkProgram "" FAILED
      Program "" infolog:

      PLIZE Help!!!!
