C++ (Cpp) float4x4::Row Examples

Example #1

File: AABB.cpp Project: katik/naali

void AABB::TransformAsAABB(const float4x4 &transform)
{
	assume(transform.IsColOrthogonal3());
	assume(transform.HasUniformScale());
	assume(transform.Row(3).Equals(0,0,0,1));

	AABBTransformAsAABB(*this, transform);
}

Example #2

File: TransformOps.cpp Project: juj/MathGeoLib

float4x4 operator *(const TranslateOp &lhs, const float4x4 &rhs)
{
	// This function is based on the optimized assumption that the last row of rhs is [0,0,0,1].
	// If this does not hold and you are hitting the check below, explicitly cast TranslateOp lhs to float4x4 before multiplication!
	assume(rhs.Row(3).Equals(0.f, 0.f, 0.f, 1.f));

	float4x4 r = rhs;
	r.SetTranslatePart(r.TranslatePart() + DIR_TO_FLOAT3(lhs.Offset()));
	return r;
}
