示例1: clamp

fixed CTerrain::GetExactGroundLevelFixed(fixed x, fixed z) const
{
	// Clamp to size-2 so we can use the tiles (xi,zi)-(xi+1,zi+1)
	const ssize_t xi = clamp((ssize_t)(x / (int)TERRAIN_TILE_SIZE).ToInt_RoundToZero(), (ssize_t)0, m_MapSize-2);
	const ssize_t zi = clamp((ssize_t)(z / (int)TERRAIN_TILE_SIZE).ToInt_RoundToZero(), (ssize_t)0, m_MapSize-2);

	const fixed one = fixed::FromInt(1);

	const fixed xf = clamp((x / (int)TERRAIN_TILE_SIZE) - fixed::FromInt(xi), fixed::Zero(), one);
	const fixed zf = clamp((z / (int)TERRAIN_TILE_SIZE) - fixed::FromInt(zi), fixed::Zero(), one);

	u16 h00 = m_Heightmap[zi*m_MapSize + xi];
	u16 h01 = m_Heightmap[(zi+1)*m_MapSize + xi];
	u16 h10 = m_Heightmap[zi*m_MapSize + (xi+1)];
	u16 h11 = m_Heightmap[(zi+1)*m_MapSize + (xi+1)];

	// Intermediate scaling of xf, so we don't overflow in the multiplications below
	// (h00 <= 65535, xf <= 1, max fixed is < 32768; divide by 2 here so xf1*h00 <= 32767.5)
	const fixed xf0 = xf / 2;
	const fixed xf1 = (one - xf) / 2;

	// Linearly interpolate
	return ((one - zf).Multiply(xf1 * h00 + xf0 * h10)
	              + zf.Multiply(xf1 * h01 + xf0 * h11)) / (int)(HEIGHT_UNITS_PER_METRE / 2);

	// TODO: This should probably be more like GetExactGroundLevel()
	// in handling triangulation properly
