摘要： Un aspect de l'invention concerne un procédé de calcul d'un score de visibilité d'au moins un objet dans une scène en trois dimensions, comprenant les étapes suivantes mises en oeuvre par une caméra dédiée clone d'une caméra principale et associée à un pipeline graphique dédié :
- Sélection d'au moins un objet (600) parmi la pluralité d'objets de la scène,
- Association de l'objet sélectionné (600) à une image de texture ne comportant qu'une seule couleur prédéterminée,
- Rendu, par la caméra dédiée, de la scène pour produire au moins une image dédiée (70),
- Pour l'objet (600) sélectionné,
- Lecture, dans l'image dédiée (70), de la couleur (710) en au moins un point correspondant à l'objet (600) dans la au moins une image dédiée (70),
- Comparaison de la couleur lue (710) avec la couleur prédéterminée pour obtenir le score de visibilité associé à l'objet (600).

摘要： Hidden surface removal logic and methods for performing full resolution depth testing in a graphics processing system in which a rendering space is subdivided into a plurality of tiles and each tile comprises a plurality of pixel samples. The hidden surface removal logic is configured to: receive a primitive fragment of a set of primitive fragments associated with a tile of the plurality of tiles, the primitive fragment corresponding to a pixel sample of the tile; receive information indicating whether the primitive fragment requires a depth buffer read for full resolution hidden surface removal; if the primitive fragment is a first primitive fragment in the set, initialize a current best depth value buffer for the tile and a depth value update map for the tile, wherein the current best depth value buffer for the tile comprises a depth value for each pixel sample of the tile, the depth value update map indicates which values of the current best depth value buffer have been updated, and the depth value update map is initialized to indicate that no depth values in the current best depth value buffer have been updated; determine whether the primitive fragment has a best depth value for the pixel sample corresponding to the primitive fragment according to a depth compare mode; and in response to determining that the primitive fragment has the best depth value for the pixel sample corresponding to the primitive fragment, update the depth value for that pixel sample in the current best depth value buffer with the depth of the primitive fragment, and update the depth value update map to indicate that the depth value for that pixel sample has been updated; wherein, when the first primitive fragment does not require a depth buffer read, initializing the current best depth value buffer comprises initializing each depth value in the current best depth value buffer to a worst depth value according to the depth compare mode, and, when the first primitive fragment requires a depth buffer read, initializing the current best depth value buffer comprises initializing each depth value in the current best depth value buffer to the corresponding depth value in the depth buffer for the tile..

摘要： Methods and graphics processing units are provided for processing a plurality of fragments a graphics processing system. The system comprises: (i) hidden surface removal logic, and (ii) processing logic configured to execute shader programs for fragments. A first fragment to be processed is received, wherein the first fragment has a shader-dependent property. The first fragment is processed by: performing an early depth test on the first fragment with the hidden surface removal logic using a depth buffer; in response to the first fragment passing the early depth test, executing one or more instructions of a shader program for the first fragment on the processing logic to determine the property of the first fragment; and after the determination of the property of the first fragment, performing a late depth test on the first fragment with the hidden surface removal logic using the depth buffer. After said receiving a first fragment, a second fragment to be processed is received, wherein the second fragment does not have a shader-dependent property. The second fragment is processed by, before said late depth test is performed on the first fragment, performing an early depth test on the second fragment with the hidden surface removal logic.

摘要： A compiler configured to analyse a shader program which is for execution in a graphics processing system which comprises: (i) hidden surface removal logic configured to perform hidden surface removal on fragments, and (ii) processing logic configured to execute shader programs for fragments, wherein one or more of the fragments has a shader-dependent property, the compiler being configured to: identify an instruction in the shader program which can affect the shader-dependent property of a fragment; split the shader program into stages by splitting the shader program at a point after the identified instruction in the shader program; and store the stages of the shader program in a memory, wherein the graphics processing system can read the stages of the shader program from the memory.

摘要： A computer-implemented method of determining an extent to which an object in a computer-generated scene is visible from a virtual camera, including rendering the computer-generated scene, generating a plurality of points distributed across a surface of the object, determining a depth map value for each point within a field of view of the virtual camera, determining whether each such point is visible from the perspective of the virtual camera based on a comparison between the determined depth map value for the point and a corresponding one or more depth map values stored in a depth buffer populated during the rendering, and determining the extent to which the object is visible in dependence on which of the plurality of points are determined to be visible from the perspective of the virtual camera.
