Title: Tessellation method using recursive sub-division of triangles
Inventor: PETER MALCOLM LACEY
IPC: G06T17/20
Filed: 2020-07-15
Abstract: To provide a tessellation method which uses vertex tessellation factors defined for each vertex of a patch which may be a quad, a triangle or an isoline.SOLUTION: This method is implemented in a computer graphics system. This method involves comparing vertex tessellation factors to a threshold. If the vertex tessellation factors for either a left vertex or a right vertex, which define an edge of an initial patch, exceed the threshold, the edge is sub-divided by addition of a new vertex which divides the edge into two parts, and two new patches are formed. Vertex tessellation factors are calculated for each vertex in each of the newly formed patches including the newly added vertex. This method is then repeated for each of the newly formed patches until none of the vertex tessellation factors exceed the threshold.SELECTED DRAWING: Figure 5
