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);
}
}


(Thanks Dan)

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)

(Thanks to Dan)
