Term
Vergence-Accommodation Conflict
Definition
mismatching cues between distance of a virtual object and your focus

Term
Difference between Gouraud Shading and Phong Shading
Definition
* Gouraud shades each vertex and fills triangles using interpolation
* Phong Shading actually performs a shading computation using a reflection model at each pixel and not just at the vertices
Term
Colors barycentric
