Acrylic Material

Hello,
I have a question about acrylic materials. i wanna to modelling a
trapezoidal shape with acrylic material. I hope Radiance can simulate the
behaviour of light direction, such as refraction dan internal reflection.

I have tried to give dielectric material, but failed.
and then i wanna give a prism material, but in prism materials the shape
must be a planar shape. but the shape that i want is trapezoidal.

the image of shading acrylic that i want can be downloaded in

Hi Christy,

This is a case where you may need to use genBSDF to create a virtual system using your prismatic panel, which can be modeled with the genprism command. You need to pay careful attention to the man page:

  http://www.radiance-online.org/learning/documentation/manual-pages/pdfs/genprism.pdf

In particular, the direction you extrude the surface determines the orientation of the normals, which matters for the dielectric material type.

Following genprism, you can use the xform command with a -a option to repeat the extruded prism as many times as needed with the appropriate positioning (-t option).

The genBSDF command can be used with pkgBSDF to place the final system into your scene.

You could also try rendering using the new photon map routines that have been recently added to the Radiance HEAD by Roland Schregle, but this is only if you have the most up-to-date binaries.

Unfortunately, none of these steps are simple, and this is a good challenge for an advanced Radiance user. It would probably take me several hours to do, myself.

Cheers,
-Greg

hi, i've just install radiance 5.0.a-win32. i I has been successfully gener
ate global photon map using command:
mkpmap -apg scene.gpm 10000 -apo prisma1a -t 60 tes.oct

But, failed when rpict. the command is:
rpict -ab 1 -apg scene.gpm 50 -vp 0.013 3.127 1.510 -vd 5.385 0.025 -0.040
-vu 0 0 1 -vh 60 -vv 34 -vs 0 -vl 0 tes.oct

The error message is:
rpict: fatal - command line error at '-apg'
rpict: 0 rays, 0.00% after 0.0000 hours

Going by the man page, the rpict option is just "-ap" not "-apg", though that is the correct option for mkpmap.

Try it!
