light pipe using RGB LED source
Posted: Sun Feb 18, 2018 6:33 pm
Hi,
I'm testing the sanity of new lux core. I'm trying to use a real world dimensioned LED light source (modeled from OSRAM datasheet type LTRB GFSF).
This light source emits red, green and blue light, each from an individual chip. Unfortunatly I don't know how to attach a spectrum in new lux core.
The classic lux offers the "tabulated data" texture for this tasks.
To receive any kind of result I've used RGB values to describe the color of each chip.
First render test is a clear PMMA volume (n=1,492 - no dispersion) guide that is swept in a rectangular profile.
The back-surface contains a rough glass definiton (0,33) - all the other faces are perfectly clear.
The camera is set to linear tone mapping.
Watching an intermediate result (after 1 day) shows that it may has some over exposure. Is it possible to adjust camera settings while rendering (like in classic UI)
Actually I've expected to see some non mixed colors at the very beginning of the pipe.
I don't know whether its the missing spectrum or the camera settings.
