Abstract
When performing ray tracing in a graphics processing system a ray tracing acceleration data structure comprising nodes having associated bounding volumes is provided for use when determining a sub-triangle of a displacement micromapped triangular primitive that may be intersected by a ray. The bounding volumes of the nodes of the ray tracing acceleration data structure comprise volumes having triangular ends and are formed by the triangular ends and planes joining corresponding sides of the triangular ends of the volume. When a ray intersects the triangular primitive having the associated displacement micromap, the ray tracing acceleration data structure for the primitive is traversed for the ray.
