Subject: [osg-users] Mesh generation using Vertex Buffer and Index Buffer
in OpenSceneGraph

Assume that I have a Vertex Buffer and Index Buffer, Using OpenSceneGraph,
Can I render a mesh, Similar to the way, we use
glVertexBuffer and glIndexBuffer and glDrawElements in OpenGL,  to render a
mesh.

or Using glVertex3fv in the following way


Code:


glBegin(GL_TRIANGLES);
for (i = 0; i < 20; i++) {
/* color information here */
glVertex3fv(&vdata[tindices[i][0]][0]);
glVertex3fv(&vdata[tindices[i][1]][0]);
glVertex3fv(&vdata[tindices[i][2]][0]);
}
glEnd();




Are there any commands, similar to glVertexBuffer,  glIndexBuffer
glDrawElements and  glVertex3fv.

I tried with osgDeluanay, but not getting the correct output.

Please consider this a newbie question.
