Irrlicht Engine

Translate the node to the centre, rotate it, translate it back. If this is too hard, rotate it as you have done then translate it back to its initial position. Or, centre the entire scene on the node.
I found my problem, the model was exported from 3D max and saved its relative position in 3D max ...

I added a node to the scene, and changed its position, then I added a rotation animator(vector(0, 1.5, 0)) to the node, but the node feels like rotating around the center of the scene. How to rotate a node around its central axis? Thanks.

That works perfect thank you

Yeah, that's exactly what I want, thanks dude, I'll try it tomorrow.

There are two matrix, matrixA(rotation(X1, Y1, Z1)), matrixB(rotation(X2, Y2, Z2)), and matrixC setRotationAngle((X1 + X2, Y1 + Y2, Z1 + Z2)), then finally matrixC.transformVector(VectorV) to get a vector rotation result? Suppose matrixA and matrixB have same translation and scale primitives, so ...

Setting the target only changes the view matrix, as expected. What is the issue? The projection matrix does not affect the target.

if(mpHmd)
{
ovrHmd_BeginFrame(mpHmd, 0);

//Get eye poses, feeding in correct IPD offset
ovrVector3f ViewOffset[2] = {mpVrData->EyeRenderDesc[0 ...

Hi, I am new to irrlicht and new to 3D programming, recently I'm doing a vr project, I set the camera's projection matrix from the vr glasses' result, and now I need to set the 'right' target to 'fit' the new projection matrix, for which I mean is the target-posistion vector is at the center of the ...
