Mesh "streaming" system

Nice, but if you're serious about this I suggest looking up oct_trees or a similar proven method.(I'm assuming you havn't.)

Just to show how simple this makes the actual rendering, here's a recurvise oct_tree function, that can cull whole chunks of geo with simple frustum collision checking.

Function oct_renderNode(node.octNode,checkBounds=True)
		box.bound=node\box
		seen=False
		size#=box\w/2
checkbounds=False
If checkBounds
		Select CubeFrustumState(box\x+box\w/2,box\y+box\h/2,box\z+box\d/2,box\size/2)
			Case 0
				Return
			Case 2
				For j=0 To nodes-1
					oct_renderNode(node\child[j],0)
				Next	
				
			Case 1
				For j=0 To nodes-1
					oct_renderNode(node\child[j],True)
				Next
		End Select
		If node\nodes=0
			For j=0 To node\srfc-1
				setUpScene(node\srf[j]\ent,node\srf[j]\srf)
				setupSurfacesWithTris(node\srf[j]\srf,node\srf[j]\ent,node\srf[j]\ctris[0],node\srf[j]\triBuf[0])
				glDrawElements2(GL_TRIANGLES,(BankSize(node\srf[j]\ctris[0])/12)*3,GL_UNSIGNED_INT,0)
				rends=rends+BankSize(node\srf[j]\ctris[0])/12
			Next
		EndIf
Else
	If node\nodes=0
		If  CubeFrustumState(box\x+box\w/2,box\y+box\h/2,box\z+box\d/2,box\size/2)
			For j=0 To node\srfc-1
				setUpScene(node\srf[j]\ent,node\srf[j]\srf)
				setupSurfacesWithTris(node\srf[j]\srf,node\srf[j]\ent,node\srf[j]\ctris[0],node\srf[j]\triBuf[0])
				glDrawElements2(GL_TRIANGLES,(BankSize(node\srf[j]\ctris[0])/12)*3,GL_UNSIGNED_INT,0)
				rends=rends+BankSize(node\srf[j]\ctris[0])/12
			Next
		EndIf
	Else
		For j=0 To nodes-1
			oct_renderNode(node\child[j],False)
		Next
	EndIf
EndIf
End Function
