User:Kunigami/GSoc2011/RT Parameters Proposal

This page is a draft to present the new options to be added RT application. Waiting for review before implementing.

Usage

-L # #

The first number will define the firing pattern and the second one the frequency on which the framebuffer will be updated.

- Firing Pattern options:

1. Normal (default)
2. Increasing
3. Multiple Samples
4. Random

- Frequency of updates

1. Unbuffered - updates after every pixel
2. Scanline - updates after each line (default, except for Random)
3. Image - updates only after the image is finished
4. Frame - updates after each frame is finished (only makes sense for multi-frames mode)

Table of valid combinations

Fire\Freq	1	2	3	4
1	X	X	X
2	X	X		X
3	X	X		X
4	X

Examples

./rt -L"1 2" -- the same as default ./rt -L"4" -- unbuffered random mode ./rt -L"3" -- scanline multi-sample mode ./rt -L"3 1" -- unbuffered multi-sample mode
