HP sv6 manual Each fraction of the screen is called a screen rectangle, Accumulate Mode

installation and user information

product overview

NOTE Each fraction of the screen is called a “screen rectangle.”

Example: In a configuration with five workstations (one doing 2D rendering and four doing 3D rendering), each 3D workstation would output one of the four screen rectangle areas on the display.

You can specify how the screen is dissected. The basic options are grid, vertical slice, horizontal slice and pane. See the

/opt/graphics/OpenGL/sv/doc/README.setpipes file for more details.

•Accumulate Mode: Improves Image Quality

Each pipe generates the complete screen, “jittered” by sub-pixel values. These jittered images are averaged together to achieve a better quality image. This mode is sometimes referred to as the anti-aliasing mode. The more workstations you add, the more samples can be taken, and the better the resulting image quality.

Figure 2-7 Accumulate Mode

•Mixed Mode: Combination of both Accelerate and Accumulate Modes

Each screen rectangle is generated (jittered and averaged) by the number of samples designated. There is improved image quality (anti-aliasing), and also improved performance (acceleration) since each area is generated by multiple workstations.
