これは私の最初のグラフィックス対象のuniであり、実装のいくつかの部分だけが私のために働いていません。私は適切に描画する関節を得ることができますが、私は関節の間に '骨'を入れて関数を記述しようとしています。この時点では、骨は直方体に変形された立方体だけであり、後でミキサーなどから適切なモデルを導入しようとします。Kinect SDKを使用してフル3Dスケルトンを作成
私のトラブルは回転です。約5時間かかりましたが、私のパートナーと私はそれが働いていますが、腕や足を動かすと直ちに歪んで奇妙に見えます。どんな助けもありがとう。以下は、骨を描こうとする機能です。骨の向きについては
private void DrawBone(Skeleton skeleton, JointType jointType0, JointType jointType1)
{
Joint joint0 = skeleton.Joints[jointType0];
Joint joint1 = skeleton.Joints[jointType1];
// If we can't find either of these joints, exit
if (joint0.TrackingState == JointTrackingState.NotTracked ||
joint1.TrackingState == JointTrackingState.NotTracked)
{
return;
}
// Don't draw if both points are inferred
if (joint0.TrackingState == JointTrackingState.Inferred &&
joint1.TrackingState == JointTrackingState.Inferred)
{
return;
}
// We assume all drawn bones are inferred unless BOTH joints are tracked
if (joint0.TrackingState == JointTrackingState.Tracked && joint1.TrackingState == JointTrackingState.Tracked)
//jointvector(joint) takes a joint and returns a Vector2 with its position data, with the z invtred to work properly with directx11
Vector3 bonevector = Vector3.Subtract(jointVector(joint0), jointVector(joint1));
//cubevector is supposed to describe the initial vector of a cube centred at (0,0,0) with a side length of 2. A fair amount of guesswork has gone into this bit.
Vector3 cubevector = new Vector3(0, 2, 0);
//midpoint of two joints
Vector3 transTest = Vector3.Divide(Vector3.Add(jointVector(joint0),jointVector(joint1)), 2);
//divide by two because our original cube has side length 2
float scaleFactor = Math.Abs(bonevector.Length()/cubevector.Length());
//we haven't been taught quaternions in class or anything, but after a fair while searching for similar problems they seemed like the go-to option for rotations.
world = Matrix.Transformation(new Vector3(0, 0, 0), new Quaternion(0), new Vector3(0.05f, scaleFactor, 0.05f), new Vector3(0, 0, 0), new Quaternion(Vector3.Cross(cubevector, bonevector), (float)Math.Acos(Vector3.Dot(bonevector, cubevector))), transTest);
//view and proj are defined elsewhere and are working fine, it's just the world that is being lame
worldViewProj = world * view * proj;
worldViewProj.Transpose();
sDXdata.context.UpdateSubresource(ref worldViewProj, sDXdata.constantBuffer);
//36 vertices of the cube (two triangles per face) defined elsewhere
sDXdata.context.Draw(36, 0);
return;
こんにちはヴィンス、これはこれまで行ったことがありますか?モデルを3Dでどのように表示したかを理解することに興味があります。 –
