Graph rendering using 3D acceleration

Question

We generate graphs for huge datasets. We are talking 4096 samples per second, and 10 minutes per graph. A simple calculation makes for 4096 * 60 * 10 = 2457600 samples per lineg

Answer 1

You really don't have to worry about the Z-axis if you don't want to. In OpenGL (for example), you can specify XY vertices (with implicit Z=0), turn of the zbuffer, use a non-projective projection-matrix, and hey presto you're in 2D.
