A method, apparatus and computer program product utilize digital signatures to efficiently identify objects of interest within images and cause graphical presentation data to be accurately displayed for the objects of interest. The method receives one or more images generated by an image capture device. The method determines one or more digital signatures associated with one or more objects within the one or more images. Based on the one or more digital signatures, the method also determines graphical data placement information comprising one or more graphical data placement regions for the one or more objects. The method also receives graphical presentation data comprising one or more graphical assets. The method also causes display of the graphical presentation data that includes overlaying at least one graphical asset of the one or more graphical assets on the at least one graphical data placement region.

A bounce light map for a scene is determined for use in rendering the scene in a graphics processing system. Initial lighting indications representing lighting within the scene are determined. For a texel position of the bounce light map, the initial lighting indications are sampled using an importance sampling technique to identify positions within the scene. Sampling rays are traced between a position in the scene corresponding to the texel position of the bounce light map and the respective identified positions with the scene. A lighting value is determined for the texel position of the bounce light map using results of the tracing of the sampling rays. By using the importance sampling method described herein, the rays which are traced are more likely to be directed towards more important regions of the scene which contribute more to the lighting of a texel.

A platform for design of a lighting installation generally includes an automated search engine for retrieving and storing a plurality of lighting objects in a lighting object library and a lighting design environment providing a visual representation of a lighting space containing lighting space objects and lighting objects. The visual representation is based on properties of the lighting space objects and lighting objects obtained from the lighting object library. A plurality of aesthetic filters is configured to permit a designer in a design environment to adjust parameters of the plurality of lighting objects handled in the design environment to provide a desired collective lighting effect using the plurality of lighting objects.

A system for generating a path for navigating an environment, the system comprising a bounding volume hierarchy, BVH, generation unit operable to generate a BVH comprising a plurality of bounding volumes representing one or more objects in the environment, a BVH analysis unit operable to identify information about the geometry of the environment from the BVH, and a path planning unit operable to generate a path through the environment in dependence upon the identified geometry.

Disclosed herein are system, method, and computer program product embodiments for mobile device tracking system within a VR simulation. The method includes determining a position and orientation of a mobile device tracking module (e.g., case) attached to a mobile device, calculating a position and orientation of the of the mobile device based at least partially on a position and orientation of a tracking module, simulating a real world environment, generating a virtual visualization of the mobile device and rendering a VR simulation based at least partially on the position and orientation of the display screen of the mobile device. The position and orientation of the display screen provides a virtual position and orientation of the display screen relative to a virtual origin within the VR simulation.

Augmenting real-time views of a patient with three-dimensional (3D) data. In one embodiment, a method may include identifying 3D data for a patient with the 3D data including an outer layer and multiple inner layers, determining virtual morphometric measurements of the outer layer from the 3D data, registering a real-time position of the outer layer of the patient in a 3D space, determining real-time morphometric measurements of the outer layer of the patient, automatically registering the position of the outer layer from the 3D data to align with the registered real-time position of the outer layer of the patient in the 3D space using the virtual morphometric measurements and using the real-time morphometric measurements, and displaying, in an augmented reality (AR) headset, one of the inner layers from the 3D data projected onto real-time views of the outer layer of the patient.

A system of properly displaying chroma key content is presented. The system obtains a digital representation of a 3D environment, for example a digital photo, and gathers data from that digital representation. The system renders the digital representation in an environmental model and displays that digital representation upon an output device. Depending upon the context, content anchors of the environmental model are selected which will be altered by suitable chroma key content. The chroma key content takes into consideration the position and orientation of the chroma key content relative to the content anchor and relative to the point of view that the environmental model is displayed from in order to accurately display chroma key content in a realistic manner.

A bounce light map for a scene is determined for use in rendering the scene in a graphics processing system. Initial lighting indications representing lighting within the scene are determined. For a texel position of the bounce light map, the initial lighting indications are sampled using an importance sampling technique to identify positions within the scene. Sampling rays are traced between a position in the scene corresponding to the texel position of the bounce light map and the respective identified positions with the scene. A lighting value is determined for the texel position of the bounce light map using results of the tracing of the sampling rays. By using the importance sampling method described herein, the rays which are traced are more likely to be directed towards more important regions of the scene which contribute more to the lighting of a texel.

Video conferencing can be provided between a first participant using first augmented reality, AR, glasses with a first forward facing glasses camera and using a first conferencing camera and a second participant using second AR glasses with a second forward facing glasses camera and using a second conferencing camera.
