Flag name |
Meaning |
RGBCOLORS |
do computations in RGB color space instead
of CIE XYZ |
LONG_FNTITLE |
use full file path name as a window title |
SOFT_ID_RENDERING |
some hardware OpenGL implementations return
rubbish when reading back the framebuffer in areas of the canvas window
that are obscured by GUI (e.g. menu) widgets. One way to circumvent this
problem is to use software ID rendering. This flag enables software ID
rendering. Although slower than hardware ID rendering, it is recommended. |
SLOW_RENDERER |
when navigating using the mouse, waits
for redisplaying the image until the mouse is released, instead of redisplaying
continuously. Recommended for slow renderers, or when rendering over a
slow network. |
OSMESA |
include off-screen rendering feature.
Requires Mesa3d library (www.mesa3d.org). |
LOWMEM_INTERSECT |
use slower ray-polygon intersection code,
at the benefit of saving storage (36 bytes per patch). - The default |
FAST_INTERSECT |
use old-style ray-tracing code (faster,
but requires 36 more bytes per patch and sometimes makes small mistakes) |
CHECK_INTERSECT |
for debugging, compares fast and default
ray-polygon intersection tests to see whether they agree or not |
NOINT64 |
compile without 64-bit integer code. Define
this symbol if your compiler complains that it does not know the data type
'unsigned long long'. The disadvantage is that the Niederreiter quasi-random
sequence used in stochastic Jacobi radiosity may overflow when you try
to render very large models with sensitive refinement. |
ASK_FOR_FILENAME |
ask for a file name to save a raytraced
image when pressing the ray tracing Run button. Default is not to ask for
a file name to store the raytraced image: you can always save the current
raytraced image using the 'Save Image' button in the raytracing menu. |
GIDEBUG |
include Debug menu in GUI. The Debug menu
contains tools to debug/test/demonstrate parts of RenderPark. Not useful
for the casual user. |
RTDEBUG |
nclude ray tracing debug code |
DO_BACKFACE_CULLING_YOURSELF |
in Galerkin radiosity and Monte Carlo
radiosity, performs backface culling in software instead of in hardware,
in order to avoid some strange interaction between backface culling and
the use of display lists |
NO_VRML |
compile without XRML parser library support.
e.g. because you do not want to use this library, or you can't get it compiled
or whatever. This does not affect VRML output: saving the "illuminated"
model after radiosity computations to a VRML file remains possible even
if RenderPark is compiled with this flag. |
NO_TIFF |
if you don't have the TIFF library on
your system |
OLD_TIFF |
if you have a version of the TIFF library
prior to version 3.4beta037 (august 1997). Only this version of the TIFF
library and more recent versions contain support for the Greg Wards high
dynamic range logluv image encoding. When this symbol is defined, you will
not be able to save High Dynamic Range raytraced images using the
.logluv image filename extension. |
NOPOOLS |
use standard alloc() and free() instead
of Pools library for memory management. The pools library used to provide
much faster and compact memory management than the standerd memory management
on older UNIX systems. Nowadays however, the benefit is doubtful and moreover,
the pools library appears to have strange bugs. So always define this flag. |
NAN_CHECKS |
enable not-a-number checks in the code
- for debugging |
DEBUGASSERTS |
enable assert() statements in the code
- for debugging |
INFO |
enables display of certain informational
messages. Not very useful. |
DRAND_LRAND_HAVE_NO_PROTOTYPE |
define this if drand48() and lrand48()
have no prototypes in math.h or stdlib.h on your system. Most systems do
have such prototypes, but if they don't, you may get strange crashes and
scrambled images and such. |
ALL_DOUBLE |
do all floating point computations with
double floating point numbers instead of single floating point numbers |
SANITY_CHECKS |
enables sanity checks in pools library
- for debugging |
VERBOSE |
enables display of all kinds of informations
messages you don't care about unless you are a developper or RenderPark
expert |
