What GLperf scripts are used for reporting results?
A. The OPC project group has approved a set of 13 GLperf scripts for reporting results within its Web publication, the GPC News. These are split into 10 RGB scripts and three color index scripts. The scripts are further divided by functionality: the OPClist scripts (RGB and color index) contain a number of tests for a variety of graphics primitives and other operations (such as window-clears). These tests are probably the closest parallel to primitive-level results available from most vendors today. Other scripts feature specific graphics operations, such as CopyPixl.rgb, DrawPixl.rgb, ReadPixl.rgb, TexImage. rgb measure glCopyPixels, glDrawPixels, glReadPixels and glTexImage2D RGB operations. DrawPixl.ndx and ReadPixl.ndx are the color index analogs to DrawPixl.rgb and ReadPixl.rgb . Remaining scripts address underlying graphics concepts that affect OpenGL performance — BgnEnd.rgb measures performance as it varies with the number of primitives batched together (in a glBegin/glEnd pai
