Number: | rdar://33931715 | Date Originated: | August 16 2017, 8:16 PM |
Status: | Open | Resolved: | |
Product: | iOS + SDK | Product Version: | 11 beta 6 |
Classification: | Serious Bug | Reproducible: | Always |
Area: SceneKit Summary: According to doc and header files: * SCNMatrix4Translate(m, t) should be equal to SCNMatrix4Mult(t, m), * SCNMatrix4Rotate(m, r) should be equal to SCNMatrix4Mult(r, m). However, the reality is: * SCNMatrix4Translate(m, t) == SCNMatrix4Mult(m, t) * SCNMatrix4Rotate(m, r) == SCNMatrix4Mult(m, r) Only SCNMatrix4Scale(m, s) is correctly equal to SCNMatrix4Mult(s, m). Steps to Reproduce: Run the sample playground and read console logs. Code: https://mega.nz/#!0DBzSJTT!DLDDwsURb9-lszL3eCM_IGHN91tRO9s-_rihYmbwzso
