Why name variables when you can use padding?

...

Forget normals, we have lovely hearts!

As in, who needs proper packing of normals into the g-buffer... when you can have those lovely heart shapes instead?

For those times when (int)(v + 0.5f) just isn't enough

inline int MyMath::floatToIntRounded(hkReal value)
{
       const hkReal lowerWhole = floor(value);
       const hkReal upperWhole = ceil(value);

       if((value - lowerWhole) < (upperWhole - value))
       {
               return floatToInt(lowerWhole + MY_EPSILON);
       }
       else
       {
               return floatToInt(upperWhole + MY_EPSILON);
       }
}

isNumber - Special optimized version

bool isNumber(const char number)
{
 std::string tmp;

 tmp += number;

 return std::string::npos != findIgnoreCase("0123456789", tmp);
}

I sure hope it'll grow into proper deferred shading some day

When non-renderers modify your renderer

Dan was wondering why none of his post-processing steps aligned anymore, might be related to this that someone had added:

// round up to nearest divisible by 8

m_sceneWidth += ((m_sceneWidth&0x7) ^ 0x7) + 1;

m_sceneHeight += ((m_sceneHeight&0x7) ^ 0x7) + 1;

(1600,1200) became (1608,1208)
