TVMiniMesh.SetRotationArray() is broken

[Mietze]

Hey,

I just found out that TVMiniMesh.SetRotationArray() does not work as expected in the managed dll. I expect the following code to do the same, but unfourtunately the SetRotationArray() seems to add a random rotation. The TVMiniMesh uses Meshs for instancing and no billboards.

Code:

m_pMiniMesh.SetRotationArray(nInstances, vaRotationArray);

for (int i = 0; i < nInstances; i++)
    m_pMiniMesh.SetRotation(vaRotationArray[i].x, vaRotationArray[i].y, vaRotationArray[i].z, i);

Are you using radians or degrees?

[Mietze]

Radians

[jviper]

...and what you you have set for the TVEngine.SetAngleSystem? Is that Degrees or radians?

[Mietze]

Also radians Meh.. I use TV3D for almost five years

[jviper]

hmm.....strange, perhaps internally it's always using degrees....unless....
when you say it "adds random rotation", does it seem to change rotation even when you do not?

[Mietze]

Nope, this would only happen when using billboards with a certain rotation mode, wouldn't it?

[jviper]

well what I meant is, is there erratic rotation? Like say you set rotation to (0,0,0). Does it go to (0,90,23) then to (234,210,23), (34,22,230), (4,95,242)....ect? Or does it stay still after you set the rotation but rotations just seems off?

[Mietze]

It seems like there is no erratic rotation, its more like a constant factor. The weird thing is, that after a SetRotation(0, 0, 0) a GetRotation() returns something different :/

[jviper]

hmm....does SetMatrixArray work?

[ZaPPZion]

do you have any rotations applied when adding the mesh to the minimesh? like a random value to make it look more natural? might be a bug that it keeps that value?

Well I don't know exactly what's going on, the code seems ok.
It's maybe the managed wrapper that corrupts the data someway.

But BTW I fixed a bug in that function, because it didn't work if you were in Degrees mode
