Bug ID: 110516
Summary: OpenGLCurveEvaluator does not return affine
coordinates
Product: Mesa
Version: 19.0
Hardware: All
OS: All
Status: NEW
Severity: major
Priority: medium
Component: GLU
Assignee: mesa-dev@lists.freedesktop.org

fix for bug report
According to the spec the GLU_NURBS_VERTEX and GLU_NURBS_VERTEX_DATA callbacks
should always return affine coordinates. But in case of a NURBS curve
definition in homogeneous coordinates it returns homogeneous coordinates. The
transformation to affine coordinates is missing. See accompanying patch for a
fix.
