Subject: Covert PBRT left-hand coordsys to OpenGL right-hand

---

Hi,

i am working with a programme to render the PBRT scene with OpenGL.
Unfortunately i found PBRT is based on left-hand coordinate system. i
need convert all primitives and transform data to right-hand format.

point.z -= point.z can convert all point data in the primitives
presentation correctly.

my question is how to convert a 4x4 transform matrix correctly which
contain some basic transform matrix product. (eg. translate, rotate,
scale, lookat etc.,)

i google it and havent found a exact explanation. so i seek help here.

it would be appreciated for some advice or discussion.
