Tally

Edit

Tally objects are able to measure events on the GPU. Tallies can measure three types of things:

• time - measures elapsed GPU time.
• pixel - measures how many pixels were rendered, which can be used for occlusion culling.
• shader - measure how many times shaders were run.

Tally objects can be created with up to 4096 slots. Each slot can hold a single measurement value. Pass:tick is used to begin a measurement, storing the result in one of the slots. All commands recorded on the Pass will be measured until Pass:tock is called with the same tally and slot.

The measurement value stored in the slots can be copied to a Buffer using Pass:copy, or they can be read back to Lua using Pass:read.
