Indexed Interleaved VBO

[Riven]

I have 2 VBOs, one for the interleaved geometry (T+N+V) and one for the indices.

the code looks like this:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20

int sizeof = 4;          glEnable(GL_VERTEX_ARRAY);          glEnable(GL_TEXTURE_COORD_ARRAY);          glEnable(GL_NORMAL_ARRAY);          // setup of vboData and vboIndices          // these work fine, as it works with glDrawArrays          glBindBufferARB(GL_ARRAY_BUFFER_ARB, vboData.pointer);          glInterleavedArrays(GL_T2F_N3F_V3F, 0, 0);          glVertexPointer(3,   GL_FLOAT, (2 + 3 + 3) * sizeof, (2 + 3) * sizeof);          glNormalPointer(     GL_FLOAT, (2 + 3 + 3) * sizeof, (2) * sizeof);          glTexCoordPointer(2, GL_FLOAT, (2 + 3 + 3) * sizeof, (0) * sizeof);          glBindBufferARB(GL_ELEMENT_ARRAY_BUFFER_ARB, vboIndices.pointer);          System.out.println("errorPre  = " + glGetError());          glDrawElements(GL_QUADS, vboIndices.elements, vboIndices.format, 0);          System.out.println("errorPost = " + glGetError());

Output:

1   2

errorPre  = 0 errorPost = 1280

1280 = INVALID_ENUM
This should only be 1280 when "mode" (GL_QUADS) is invalid, according to the GL-spec.


Could anybody help me on this?
