C++ (Cpp) Matrix4::setValue примеры использования

Пример #1

Файл: actor.cpp Проект: Nitrus/residualvm

Math::Matrix4 VisualActor::getModelMatrix(const Math::Vector3d& position, float direction) {
	Math::Matrix4 posMatrix;
	posMatrix.setPosition(position);

	Math::Matrix4 rot1;
	rot1.buildAroundX(90);

	Math::Matrix4 rot2;
	rot2.buildAroundY(270 - direction);

	Math::Matrix4 scale;
	scale.setValue(2, 2, -1.0f);

	return posMatrix * rot1 * rot2 * scale;
}

Пример #2

Файл: prop.cpp Проект: ComputeLinux/residualvm

Math::Matrix4 VisualProp::getModelMatrix(const Math::Vector3d& position, float direction) {
	Math::Matrix4 posMatrix;
	posMatrix.setPosition(position);

	Math::Matrix4 rot1;
	rot1.buildAroundX(90);

	Math::Matrix4 rot2;
	rot2.buildAroundY(270 - direction);

	Math::Matrix4 scale;
	scale.setValue(2, 2, -1.0f);

	Math::Matrix4 modelTransform = _model->getTransform();

	// FIXME: Why has the scale to be after the model transform?
	return posMatrix * rot1 * rot2 * modelTransform * scale;
}
