Dumping an STD::Vector into a VBO

Recommended Posts

Hello, I was wondering if this code makes sense...
std::vector<GLfloat> Indexes;

...Some code to populate the vectors...

glBufferDataARB(GL_ARRAY_BUFFER_ARB, sizeof(GLfloat)*(myModel->Indexes.size()), &myModel->Indexes[0], GL_STATIC_COPY_ARB);

...In the draw loop...
		glVertexPointer(3, GL_FLOAT, 0, 0);
		glDrawArrays(GL_QUADS, 0, myModel->mIndexToRawDraw.size()); 
I have noticed a strange issue, that when using simple shapes many of the vericies are missing. For example, a box made with a 3d modeler will have its back missing.
