Abstract: The present technology pertains to validating a virtual camera in a simulation environment by utilizing an improved camera model to provide quantitative measurements of the model's performance. A method of validating a virtual camera in a simulation environment comprises presenting at least one reference chart in the simulated environment and capturing images of the reference chart in the simulated environment using a virtual camera. The method further includes interrupting an image pipeline of the virtual camera after at least one simulated process in the image pipeline to extract a RAW image. The method analyzes the RAW image to derive measurements of metrics to characterize the virtual camera. The measured metrics are compared to metrics of a calibrated real-world camera to verify that the metrics are within a threshold delta that is indicative that the virtual camera sufficiently approximates the real-world camera.

Abstract: Methods, systems and apparatuses may provide for technology that determines the size of a graphics primitive, renders pixels associated with the graphics primitive on a per tile basis if the size exceeds a threshold, and renders the pixels associated with the graphics primitive in a mesh order if the size does not exceed the threshold. In one example, the technology discards state data associated with the graphics primitive in response to a completion of rendering the pixels associated with the graphics primitive in the mesh order.

Abstract: Methods and ray tracing units are provided for performing intersection testing for use in rendering an image of a 3-D scene. A hierarchical acceleration structure may be traversed by traversing one or more upper levels of nodes of the hierarchical acceleration structure according to a first traversal technique, the first traversal technique being a depth-first traversal technique; and traversing one or more lower levels of nodes of the hierarchical acceleration structure according to a second traversal technique, the second traversal technique not being a depth-first traversal technique. Results of traversing the hierarchical acceleration structure are used for rendering the image of the 3-D scene. The upper levels of the acceleration structure may be defined according to a spatial subdivision structure, whereas the lower levels of the acceleration structure may be defined according to a bounding volume structure.
