Shininess value mis-interpreted #9

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Material files have been known to use Ns values (Shininess) values in the range 
of 0-1000.  The 
Wave front loader cleanly passes the value into openGL which uses a 0-128 value 
limit on this 
data.  Thusly, we need to ratio the data.  If anyone has shininess issues... 
here is the fix>>

Open:
OpenGLWaveFrontMaterial.m:65

Was:

else if ([parseLine hasPrefix:@"Ns "])
    material.shininess = [[parseLine substringFromIndex:3] floatValue];

Change To:

else if ([parseLine hasPrefix:@"Ns "])
    material.shininess = ([[parseLine substringFromIndex:3] floatValue] / 1000) * 128;
