2 .TH BSDFVIEW 1 8/11/2017 RADIANCE
3 .SH NAME
4 bsdfview - view a BSDF representation
5 .SH SYNOPSIS
6 .B bsdfview
7 [
8 .B "\-q {Hi|Med|Lo}"
9 ][
10 rad options
11 ]
12 input ..
13 .br
14 .SH DESCRIPTION
15 .I Bsdfview
16 renders a BSDF description interactively.
17 This is a script that creates a rad input file (RIF)
18 then calls
19 .I rad(1)
20 to make an octree via
21 .I bsdf2rad(1),
22 then views the scene interactively.
23 .PP
24 The input is either a single XML file, such as might be produced by
25 .I genBSDF(1),
26 .I bsdf2klems(1),
27 or
28 .I bsdf2ttree(1),
29 or up to four scattering interpolation representation (SIR) files, as
30 might be produced by
31 pabopto2bsdf(1).
32 .PP
33 A rad input file will be produced, whose name matches the root of
34 the first input file but with any leading path removed (i.e., in
35 the current directory).
36 This RIF may be reused for subsequent viewing and rendering via
37 .I rad
38 without incurring the cost of another call to
39 .I bsdf2rad.
40 .PP
41 The quality preference may be set via the
42 .I \-q
43 option.
44 The number of processors to use may be specified with the
45 .I \-n
46 option.
47 .PP
48 The program creates a number of views accessible via the
49 .I rvu(1)
50 "L" command:
51 .TP 10n
52 .BR def
53 The default view, showing the back and front BRDFs.
54 .TP
55 .BR fr
56 A view of the front reflection hemisphere.
57 .TP
58 .BR br
59 A view of the back reflection hemisphere.
60 .TP
61 .BR ft
62 A fisheye view of the front transmission hemisphere (from underneath).
63 .TP
64 .BR bt
65 A fisheye view of the back transmission hemisphere.
66 .TP
67 .BR pr
68 A parallel view of both reflection hemispheres from directly overhead.
69 .TP
70 .BR pt
71 A parallel view of both transmission hemispheres from directly underneath.
72 .PP
73 Additionally, all the standard views that
74 .I rvu
75 defines will be available (e.g., "xZ", "zl", etc.).
