[Radiance-general] Beginners Questions

[Santiago Torres]

Hi,

cat is a Unix program, so it should be available under OSX and Linux, but not under Windows. Wikipedia says the command ¡°type¡± is an equivalent, but I haven¡¯t tried it.

About genprism, I think the argument before the vector should be -l (lower case ¡®L¡¯) not -1 (the number one), I¡¯m not sure which one you¡¯ve used, but may be worth checking.

Hope this helps.
Santiago

I¡¯m working through the tutorials in Rendering with Radiance & have 2 commands that I¡¯m having trouble with so far.


1.       !cat (concatenate)  - from page 80 in book ¨C Scene 1 Tutorial, section 2.5 - is this still a valid command?  I couldn¡¯t find an executable file for it in my  Radiance directory & a search online didn¡¯t bring up reference to it either.    The error I get when I try to run oconv is ¡°Can¡¯t find executable for ¡°cat¡± .system ¨C cannot execute ¡°!cat ./lib/table_1.rad¡±



2.       Genprism ¨C from page 53 in book ¨C I can run genprism if I don¡¯t put in the final 4 extrusion factors.   What am I doing wrong?
If I run the command as written in the book:  genprism brown_satin_paint stool_leg_sw 4 -0.7 -0.7 -0.6 -0.7 -0.6 -0.6 -0.7 -0.6 -1 0 0 2.5 > look.txt
I get the following error:               Usage:  genprism material name { - | vfile | N v1 v2 .. vN} [-1 1vect] [-r radius] [-c][-e]

If I run the command without the extrusion vector (final 4 #¡¯s) it creates the prism with the ¡®z¡¯ values at 1 which I¡¯m guessing is the default.

Thank you for help!!
