NAME

tachyon-nox - parallel/multiprocessor ray tracer with no X support

SYNOPSIS

tachyon-nox modelfile [options]

DESCRIPTION

Valid options and accepted formats are as follows (** denotes default behaviour).

Model file formats supported:

the model files originated with this package
AC3D model files
the NFF scene format used by Eric Haines' SPD

Message Options:

+V
verbose messages on
verbose messages off **

Speed Tuning Options:

maximum ray recursion depth
(** default is auto-determined)

-nobounding

(** default threshold is 16)

Shading Options:

best quality rendering (and slowest) **
good quality rendering, but no shadows
low quality rendering, preview (and fast)
worst quality rendering, preview (and fastest)

Lighting Options:

specified factor (performed before other lighting overrides take effect)
force use of ambient occlusion lighting, auto-rescaling direct light sources to compensate for ambient occlusion factor (use value 0.7 as a good starting point)
force use of ambient occlusion lighting, manually-rescaling direct light sources to compensate for ambient occlusion factor

-skylight_samples xxx number of sample rays to shoot

Specular Highlight Shading Options:

Phong specular highlights
Blinn's specular highlights **
fast approximation to Blinn's highlights
disable specular highlights

Transparency Shading Options:

limit the number of transparent surfaces shown to the number specified
original implementation **
Raster3D angle-based opacity modulation
opacity post-multiply used by VMD

Transparent Surface Shadowing Options:

transparent objects cast shadows **
transparent objects do not cast shadows

Fog Shading Options:

radial fog implementation **
planar OpenGL-like fog used by VMD

Surface Normal/Winding Order Fixup Mode:

-normalfixup [off|flip|guess] (** off is default)

Antialiasing Options:

maximum supersamples taken per pixel (** default is 0, or scene file determined)

Output Options:

override scene-defined output image size
set output file name
clamp pixel values to [0 to 1) **
normalize pixel values to [0 to 1)
normalize apply gamma correction
24-bit Windows BMP (uncompressed)
24-bit JPEG (compressed, but lossy)
24-bit PNG (compressed, lossless)
24-bit PPM (uncompressed)
48-bit PPM (uncompressed)
48-bit PSD (uncompressed)
24-bit SGI RGB (uncompressed)
24-bit Targa (uncompressed) **
animate using file of camera positions
disable writing of output frames to disk (only used for doing real-time rendering)

Interactive Spaceball/SpaceNavigator Control:

enable Spaceball/SpaceNavigator camera flight

-spaceballport serialportdevicename (only for serial devices)
