Can't make extrusion work

[slapin]

Hi, all!
The results I get from single-segment extrusion over a path

The code:

	Procedural::Shape *pierShape = new Procedural::Shape();
	pierShape->addPoint(6.f, 0.7f);
	pierShape->addPoint(0.f, 0.6f);
...
	Procedural::RoundedCornerSpline3 *pierCurve;
	Procedural::Path pierCurvePath;
...
	if (jp.find("pierPath") != jp.end()) {
		pierPath.reserve(jp["pierPath"].size());
		pierCurve = new Procedural::RoundedCornerSpline3();
		for (auto &jpt : jp["pierPath"]) {
			Ogre::Vector3 pt;
			from_json(jpt, pt);
			pierPath.push_back(pt);
			pierCurve->addPoint(pt);
		}
		OgreAssert(pierPath.size() > 0, "empty path");
		pierCurvePath = pierCurve->realizePath();
		Procedural::Extruder extruder;
		Ogre::MeshPtr extrudedMesh =
			extruder.setShapeToExtrude(pierShape)
				.setExtrusionPath(&pierCurvePath)
				.setEnableNormals(true)
				.setTextureRectangle(
					Ogre::RealRect(0.4f, 0.0f, 0.1f, 0.1f))
				.realizeMesh("pierPathMesh" +
					     Ogre::StringConverter::toString(
						     e.id()));

(can ignore json stuff now, the actual path is (starts with pierPath):

[{"orientation":{"w":1.0,"x":0.0,"y":0.0,"z":0.0},"position":{"x":-9966.490234375,"y":7.0036211013793945,"z":-3791.760498046875},"properties":"{\"pierDepth\":39.581451416015625,\"pierHeight\":7.724061965942383,\"pierLength\":60.0,\"pierOffset\":44.0,\"pierPath\":[{\"x\":0.0,\"y\":0.0,\"z\":0.0},{\"x\":0.0,\"y\":0.1390056610107422,\"z\":2.0},{\"x\":0.0,\"y\":0.2879347801208496,\"z\":4.0},{\"x\":0.0,\"y\":0.4421849250793457,\"z\":6.0},{\"x\":0.0,\"y\":0.5964345932006836,\"z\":8.0},{\"x\":0.0,\"y\":0.6842670440673828,\"z\":10.0},{\"x\":0.0,\"y\":0.7177095413208008,\"z\":12.0},{\"x\":0.0,\"y\":0.7020454406738281,\"z\":14.0},{\"x\":0.0,\"y\":0.6652541160583496,\"z\":16.0},{\"x\":0.0,\"y\":0.6284627914428711,\"z\":18.0},{\"x\":0.0,\"y\":0.4784627854824066,\"z\":20.0},{\"x\":0.0,\"y\":0.32846277952194214,\"z\":22.0},{\"x\":0.0,\"y\":0.17846277356147766,\"z\":24.0},{\"x\":0.0,\"y\":0.028462767601013184,\"z\":26.0},{\"x\":0.0,\"y\":-0.1215372383594513,\"z\":28.0},{\"x\":0.0,\"y\":-0.27153724431991577,\"z\":30.0},{\"x\":0.0,\"y\":-0.42153725028038025,\"z\":32.0},{\"x\":0.0,\"y\":-0.5715372562408447,\"z\":34.0},{\"x\":0.0,\"y\":-0.7215372323989868,\"z\":36.0},{\"x\":0.0,\"y\":-0.8715372085571289,\"z\":38.0},{\"x\":0.0,\"y\":-1.021537184715271,\"z\":40.0},{\"x\":0.0,\"y\":-1.171537160873413,\"z\":42.0},{\"x\":0.0,\"y\":-1.3215371370315552,\"z\":44.0},{\"x\":0.0,\"y\":-6.903621196746826,\"z\":60.746253967285156},{\"x\":0.0,\"y\":-6.903621196746826,\"z\":62.746253967285156}],\"type\":\"harbour\"}"}]

[slapin]

Looks like path produce incorrect rotations. And I don't see a way to control these...

[slapin]

Single segment vs single segment works fine:

[slapin]

However 5 points are broken:

The points:
Vector3(0, 0, 0)
Vector3(0, 0.139006, 2)
Vector3(0, 0.287935, 4)
Vector3(0, 0.442185, 6)
Vector3(0, 0.596435, 8)
Vector3(0, -6.90362, 62.7463)

So the tests were:

1. Vector3(0, 0, 0)
   Vector3(0, -6.90362, 62.7463)
   OK
2. Vector3(0, 0, 0)
   Vector3(0, 0.139006, 2)
   Vector3(0, -6.90362, 62.7463)
   OK
3. Vector3(0, 0, 0)
   Vector3(0, 0.139006, 2)
   Vector3(0, 0.287935, 4)
   Vector3(0, -6.90362, 62.7463)
   OK
4. Vector3(0, 0, 0)
   Vector3(0, 0.139006, 2)
   Vector3(0, 0.287935, 4)
   Vector3(0, 0.442185, 6)
   Vector3(0, -6.90362, 62.7463)
   OK
5. Vector3(0, 0, 0)
   Vector3(0, 0.139006, 2)
   Vector3(0, 0.287935, 4)
   Vector3(0, 0.442185, 6)
   Vector3(0, 0.596435, 8)
   Vector3(0, -6.90362, 62.7463)
   FAILURE (see screenshot).

The shape is single segment (see code above):
pierShape->addPoint(6.f, 0.7f);
pierShape->addPoint(0.f, 0.6f);

[slapin]

Catmull variant breaks tangents in different way - it rotates segments 180 degrees backwards on relative X axis unlike rounded corner variant which rotates 180 degrees around Z axis (the curve general direction axis).

[slapin]

Looks like there is some problem with UP vector calculation or something as after some segment tangets break completely.

-- manual handles, CubicHermiteSpline3, again breaks on 5th segment. Had hopes for manual handles, but problem is the same.

-- automatic handles, CubicHermiteSpline3, looks much better almost there but there is weird turn 180 degrees around X axis without any reason before curve goes down.

Looks like I can't use this as it is too unstable, and have to go back to taming primitives.

Looks like it would be much better to use quad from primitives and cross product from up and direction vector to set points, that one can't be broken in so uncontrollable way...

[slapin]

Tested all my paths using primitives and found no problems with them so I guess I'm on my own here and have to implement extrusion myself. With primitives framework it should not be too hard.

[slapin]

Made it work.
The only type of curve which works is CubicHermiteSpline3 and one must set tangent manually,
i.e.

pierCurve->addPoint(pt, Ogre::Vector3(0, 0, 1));

All other ways do not work. Automatic tangents do not work.

Finally!

[slapin]

The only problem remains is UV control. It is possible to set shape track and path track during extrusion but what they do is a big mystery as they don't get UVs to be from rectangle I expect them to be in... Kind of no idea, need to debug this... Also extruder completely ignores setting of texture rectangle setting top left corner to always zero making it useless, so I guess the bug is somehow related...

[slapin]

I create tracks and generate triangle buffer this way:

        Procedural::TriangleBuffer tb;
         ...
        Procedural::Track shapeTextureTrack =
            Procedural::Track(Procedural::Track::AM_POINT)
                .addKeyFrame(0, 0.4f)
                .addKeyFrame(2, 0.6f)
                .addKeyFrame(3, 0.8f)
                .addKeyFrame(5, 0.9f)
                .addKeyFrame(6, 1);
        Procedural::Track pathTextureTrack =
            Procedural::Track(Procedural::Track::AM_POINT)
                .addKeyFrame(0, 0.45)
                .addKeyFrame(2, .58f)
                .addKeyFrame(3, .8f)
                .addKeyFrame(5, 1);
        Procedural::Extruder extruder;
        extruder.setShapeTextureTrack(&shapeTextureTrack)
            .setPathTextureTrack(&pathTextureTrack)
            .setShapeToExtrude(pierShape)
            .setExtrusionPath(&pierCurvePath)
            .setEnableNormals(true)
            .setUTile(1.0f)
            .setVTile(1.0f)
            .addToTriangleBuffer(tb);

And dump UVs this way:

        for (const auto &v : tb.getVertices()) {
            std::cout << v.mUV << std::endl;
        }

The result:

So first 14 UVs are incorrect and the rest are controlled by tracks normally.
So there is some bug somewhere again. Fixed these in my code by manual intervention.

Looks like manual UV clamping is required on primitives too as setTextureRectangle is not reliable too...

[slapin]

Yes, manual clamping is way to go.
