Part 5: The Iterative Rendering Process
IRp Custom and presets Resolution
Most IRPs offer resolution presets. Various sizes can be selected from a pull-down menu. All 
IRPs offer custom options, allowing the resolution to be set manually.
Determining DpI
DPI is determined based on two factors:
3
3
The size of the final render
3
3
The draft-to-final iterative process
The final render size is subjective and depends on what you need to convey in the image.
As outlined in Chapter 20, resolution affects render times: higher resolutions equal longer 
times. Start with low resolutions, using IRP presets or setting custom small sizes. Here are 
some useful initial resolutions for first and second drafts:
3
3
640 (width) 
n
480 (height)
3
3
800 (width) 
n
600 (height)
Useful resolutions for third and fourth drafts can range from these initial values to 1280 
(width) 
n
720 (height). Final typical resolutions can be set between 1280 
n
720 and 1920 
n
1080.
Large Resolutions
Larger resolutions greater than 1920 
n
1080 can be set using the custom option under the IRP 
resolution menu. Large resolution images take longer to render and might require additional 
RAM (memory) to complete. This is especially true for models filled with a good amount of 
vegetation components.
When calculating custom pixel width and heights for large resolution images, use the
150 DPI value when multiplying the measured (imperial or metric) values.
