+### CUDA summary and analysis
+
+The following chart shows the approximate percentage time spent by each cuda function. It is clear that \_rasterizePrims has the largest time spent because of the calculation of barycentric coords and perspective correct texture coords.

+-------------------------
+
+This following image shows the percentage time spent while doing the wireframe for the cow.gltf
+
+![](renders/lines_summary.png)
+
+Here however, we see that the time is most spent in `initDepth`.
