problems with glVertexAttribPointer

Hi,

I'm trying to render a robot which has 7 joints. Each joint is an object called "Joint". I load the vertices correctly but I don't know why I can just see the first joint. I new in openGL so I don't understand very well if my calls are correct or not and the reason why...

Here you can check my code:

vertexArray is the array where I put my vertexs points previously.

[code]GLuint vertexs;
glGenBuffers(1,&vertexs);
glBindBuffer(GL_ARRAY_BUFFER,vertexs);
glBufferData(GL_ARRAY_BUFFER,sizeVertex*sizeof(GLfloat),vertexArray,GL_DYNAMIC_DRAW);
glEnableVertexAttribArray(0);
glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 0, 0);[/code]



the render function:
[code]
void Joint::render()
{
glDrawArrays(GL_TRIANGLES,0,sizeVertex);
}
[/code]

Can you see a problem? Thanks
