Claim 12:
13. A non-transitory computer-readable medium storing program code executable by a processor to perform operations, the operations comprising:
accessing a native base surface defined by a mesh of polygons and a map of displacement values useable to render a textured surface;
precomputing a conservative bounding volume for each polygon of the mesh of polygons, the conservative bounding volume including a portion of a displaced surface;
a step for producing a 3D position and a texture coordinate for a polygon based on an intersection of a query ray with at least one of a plurality of increasingly granular bounding volumes corresponding to the polygon and associated with the conservative bounding volume;
selectively using at least one real-time displacement parameter value to identify the at least one of the plurality of increasingly granular bounding volumes; and
rendering the textured surface using at least one of the 3D position or the texture coordinate for the polygon.
