I got a easy porblem for guru:D

Unity Engine
1

why doest object’s z coordinate is negative in the camera space,on windows
ie: objectWorld is (0.4,0.4,0.4)
cameraWorld is (-0.3,-0.3,-0.3)
the result coord caculate by this way
objectCamera=mul(UNITY_MATRIX_MV, objectWorld)
result is: (0.7, 0.7,-0.7)

why object coord in camera space is(0.7, 0.7,-0.7)?

I think that’s just the OpenGL convention: the camera is pointing in the direction of the negative z axis in camera space.
