C++ (Cpp) Matrix4::TransformVector Examples

Example #1

File: Matrix4UTests.cpp Project: iancarnation/AIE_Projects

bool M4TransformVectorTest::DoTest()
{
	Matrix4 Dummy;
	Dummy.TransformVector(m_oVector, m_fAngle, m_cAxis, m_fScale);
	cout<< "\n---------------M4TransformVectorTest---------------\n";
	return (m_oVector == m_oResult);
}

Example #2

File: BatchRenderer.cpp Project: S-V/Lollipop

void BatchRenderer::DrawArrow( const Matrix4& arrowTransform, const FColor& color, FLOAT arrowLength, FLOAT headSize )
{
	mxSWIPED("Unreal Engine 3");

	const Vec3D	origin = arrowTransform.GetTranslation();
	const Vec3D endPoint = arrowTransform.TransformVector(Vec3D( arrowLength, 0.0f, 0.0f ));
	const FLOAT headScale = 0.5f;

	const FColor& startColor = FColor::WHITE;
	const FColor& endColor = color;

	this->DrawLine3D( origin, endPoint, startColor, endColor );
	this->DrawLine3D( endPoint, arrowTransform.TransformVector(Vec3D( arrowLength-headSize, +headSize*headScale, +headSize*headScale )), startColor, endColor );
	this->DrawLine3D( endPoint, arrowTransform.TransformVector(Vec3D( arrowLength-headSize, +headSize*headScale, -headSize*headScale )), startColor, endColor );
	this->DrawLine3D( endPoint, arrowTransform.TransformVector(Vec3D( arrowLength-headSize, -headSize*headScale, +headSize*headScale )), startColor, endColor );
	this->DrawLine3D( endPoint, arrowTransform.TransformVector(Vec3D( arrowLength-headSize, -headSize*headScale, -headSize*headScale )), startColor, endColor );
}

Example #3

File: manipulator.cpp Project: S-V/Lollipop

	void Draw( BatchRenderer & batchRenderer, const Matrix4& transform, const FColor& color )
	{
		const Vec3D apex = transform.TransformVector( arrowHeadVertex );

		// draw the 'stem'
		batchRenderer.DrawLine3D( transform.GetTranslation(), apex, FColor::WHITE, color );

		// draw the arrow head
		for( UINT iSegment = 0 ; iSegment < AXIS_ARROW_SEGMENTS ; iSegment++ )
		{
			const Vec3D& p0 = transform.TransformVector( arrowVertices[ iSegment ] );
			const Vec3D& p1 = transform.TransformVector( arrowVertices[ iSegment + 1 ] );

			// Draw the base triangle of the cone.
			// NOTE: no need because we disabled backface culling
			//batchRenderer.DrawSolidTriangle3D( p0,p1,arrowBaseVertex,color );

			// Draw the top triangle of the cone.

			batchRenderer.DrawSolidTriangle3D( p0, p1, apex, color );
