Hello, everyone,
I am a newer for Volumizer. I downloaded Volumizer 2.8 and intall
it.I tried C:\Program Files\Silicon Graphics\OpenGL
Volumizer\src\apps\simple\xml\..., I met some problems.
1) When I open a .tif file, for example simple.vz, I met a runtime
error about libtiff as following.
Assertion failed!
************************************************************************
File ../../tiff-3.7.2-src/libtiff/tif_luv.c
Expression: scheme=COMPRESSION_SGILOG24 || scheme == COMPRESSION_SGILOG
************************************************************************
************************************************************************
2)I also tried the binary file. It is well for the sample binary.vz,
it is ubyte format. But when I tried a ushort file, I got the
following warning,and the rendering is not right.
Volumizer Warning:
vzLUTManager::bindLUT(): OpenGL error 1285
I used the following vz file
<?xml version="1.0"?>
<!DOCTYPE vzShapeSet SYSTEM "vzxml.dtd">
<vzShapeSet>
<vzShape id="shape1">
<vzAppearance>
<vzShader>
<vzTMLUTShader/>
</vzShader>
<vzParameterVolumeTexture name="volume">
<filename>Pana_2_30m.rec</filename>
<module name="bin">
<userString>0 300 576 576 luminance ushort</userString>
</module>
</vzParameterVolumeTexture>
<vzParameterLookupTable name="lookup_table">
<filename>DEFAULTLUT.lut</filename>
</vzParameterLookupTable>
</vzAppearance>
</vzShape>
</vzShapeSet>
And the DEFAULYLUT.lut is defined as
version_1.0
