C++ (Cpp) D3DXVec4Dot Examples

Example #1

File: FreeCameraController.cpp Project: Muret/Zephyr

void FreeCameraController::set_frame(const D3DXMATRIX& value)
{
	camera_position_ = D3DXVECTOR4(value.m[3][0], value.m[3][1], value.m[3][2], 1);

	{
		D3DXVECTOR4 view_direction = D3DXVECTOR4(value.m[0][0], value.m[0][1], value.m[0][2], 0);
		view_direction.y = 0.0f;
		D3DXVec4Normalize(&view_direction, &view_direction);

		yaw_ = acos(D3DXVec4Dot(&view_direction, &default_forward_));
	}

	{
		D3DXVECTOR4 view_direction = D3DXVECTOR4(value.m[0][0], value.m[0][1], value.m[0][2], 0);
		D3DXVECTOR4 temp = view_direction;
		view_direction.y = 0.0f;

		D3DXVec4Normalize(&view_direction, &view_direction);
		D3DXVec4Normalize(&temp, &temp);

		pitch_ = acos(D3DXVec4Dot(&temp, &view_direction));
	}

	recompute_rotation();
}
