How to convert OpenGL code to Irrlicht?

Hi everyone,

I have a problem in converting OpenGL code to Irrlicht. This code is to draw a character based on motion capture data and composed with several links such as fore arms, tights, feets, etc. However, I don't know how to convert this code to Irrlicht. If you have any idea, let me know, please.

glPushMatrix();
glTranslatef(t[0], t[1], t[2]);
glRotatef( len( rv )*180/M_PI, axis[0], axis[1], axis[2] );
// draw
glPopMatrix();

translate needs to go through quaternion and euler into setRotation, Translate can be used via setPosition. At least if there are separate meshes. Otherwise you either need to use a skeleton, or move mesh buffers. However, the latter won't have parent/child hierarchies, so calculation of positions needs to take this into consideration.

I'm pretty sure he means rotate.

Oh yeah, had my eyes on the original code, but wanted to start with the interesting part
