[Radiance-general] Rendering each matrix with 3 and 5 phase

[Thanyalak Srisamranrungruang]

Dear all,
I have been working on three and five phase methods for a couple months. I followed the two tutorials and all published presentation. I got stuck on rendering each matrix. I am trying to figure out by myself but I have not yet solved it. Here is the codes I used;

I downloaded the model from DIVA tutorial and export geometry and material to run with Radiance.
1. Rendering view matrix by using command vways pipe to rcontrib
oconv testroom.mat material.rad Reference_sky.rad Reference.rad ground.rad window.rad viewtxsursf.rad daymtxsurf.rad > Referencerender.oct

vwrays -vf Reference.vf -ff -x 500 -y 500| rcontrib -x 500 -y 359 -ld- -ffc -fo -o .\viewpics\Reference_%03d.hdr -f klems_full.cal -b kbinS -bn Nkbins -m viewsurf -ab 2 -ad 65536 -lw 1.52e-5 Referencerender.oct
Warning>>>
rcontrib: system - cannot open '.\viewpics\Reference_C:\Users\Thanyalak\Desktop\Test_5P\Reference-lessgrid\Rendering.bat3d.hdr' for writing: Invalid argument

Then I divided command into two lines

vwrays -vf Reference.vf -ff -x 500 -y 500
rcontrib -x 500 -y 359 -ld- -ffc -fo -o .\viewpics\Reference_%03d.hdr -f klems_full.cal -b kbinS -bn Nkbins -m viewsurf -ab 2 -ad 65536 -lw 1.52e-5 Referencerender.oct
There are no any outputs come out and rcontrib was continuing run about 3-4 days then I closed it.

2. Rendering view matrix by using command rways pipe to rfluxmtx
oconv material.rad Reference.rad window.rad Reference_skyrfluxmtx.rad  > Referencerender_rflux.oct
vwrays -vf Reference1.vf -ff -x 500 -y 500 | rfluxmtx -v -ffc -ab 1 -ad 65536 -lw 2e-5 - windowfluxmtx.rad -i Referencerender_rflux.oct

145 pictures were created but they can't open with wxfalsecolor.
The warnings are shown >>>
Error loading image
line 967 readImageData
Line1000 analyzeImage

Could you please give me suggestion to fix these problems?
