Nvidia patents method to draw 3D curves using angled triangle strips
Nvidia describes a way to draw smooth 3D lines by breaking them into small straight pieces. For each piece, the system uses two flat, angled shapes made of triangles to create the line's surface.
In the filing’s own words
Various examples, systems, and methods are disclosed relating to orthogonal triangle strips. A first computing system can execute one or more operations to obtain an approximation of a three-dimensional (3D) curve including a plurality of linear segments. The first computing system can execute one or more operations to determine two quadrilateral primitives (quads) for each of the plurality of linear segments using a plurality of triangle primitives, wherein each of the two quads includes two of the plurality of triangle primitives, wherein the two quads corresponding to each linear segment of the plurality of linear segments are angled relative to one another and extend along the corresponding linear segment. The first computing system can execute one or more operations to render the two quads for each of the plurality of linear segments.
What exactly they claim (claim 1)
1. A system, comprising: one or more processors to: determine two primitives for a linear segment using a plurality of triangle primitives, wherein each of the two primitives comprise two of the plurality of triangle primitives, wherein the two primitives corresponding to the linear segment are angled relative to one another; and render the two primitives for the linear segment.
