  • Patent number: 8405657
    Abstract: One embodiment of the invention sets forth a mechanism for displaying lighting values associated with a 3-D graphics model by superimposing an overlay grid with lighting values on the 3-D graphics model. A software rendering engine computes lighting values for each frame that includes the 3-D graphics model, where each frame may have different lighting settings. An overlay grid with lighting values may be superimposed on an area defined by a light meter on the 3-D graphics model. The lighting values on the overlay grid are associated with the light meter and may vary frame-over-frame. In another embodiment, a JPEG image with a superimposed overlay grid with per-pixel lighting values covering a 3-D graphics model is generated for each frame that includes the 3-D graphics model. These JPEG images may be displayed on the screen and stored to an external memory.

  • Publication number: 20100122243
    Abstract: A method for generating a library of materials that can be applied to geometry in a graphics scene when performing rendering operations. The method includes generating a class file that includes material parameters representing rendering characteristics of a material class and generating a library root file that includes a reference to the class file. The method further includes generating a rendering implementation file for translating values of the material parameters into a format recognized by a particular rendering engine and generating a user interface file that includes at least one user interface configured to allow a user to modify the values of the material parameters. The method also includes linking the class file to the library root file, and linking the rendering implementation file and the user interface file to the class file. Advantageously, the library can be organized and updated more effectively when compared to prior art techniques.

  • Publication number: 20100037205
    Abstract: A method for generating a user interface within a graphics application for a set of materials, such that each material includes a material definition and is capable of being applied to a geometry in a graphics scene when performing a rendering operation. A GUI generation engine obtains configuration information associated with an environment for a computer system and determines that a first set of materials is associated with the configuration information. The GUI generation selects the first set of materials to be displayed in a graphical user interface, and the graphical user interface is displaying to an end-user. Advantageously, embodiments of the invention provide for a technique for exposing only those materials, user interface objects, editable material parameters, user interface elements, vocabulary, rendering engines, and/or rendering engine implementations that are relevant to the user of a particular rendering application.

  • Patent number: 7594324
    Abstract: A method of assembly of a turbomachine that includes a first module and a second module with a second shaft assembled by a bearing, the bearing including an outer ring shrink-fitted inside a journal integral with the first module and an inner ring integral with the second shaft. The second module is assembled on the first module by engagement of the second shaft, with the inner ring, inside the journal. The method includes a step of inserting the second module in the first module up to a determined distance such that the first and second modules are only partially assembled. The second shaft is centered with respect to the journal, the centering being controlled on the basis of measuring distance deviations with respect to a reference on the journal. The journal is expanded by heating its outer surface. After the step of expanding, the second module is displaced inside the first module so as to complete the assembly. This displacement step is started based on a predetermined temperature.

  • Patent number: 4361783
    Abstract: The invention relates to a shooting target.The signal plate covering one of the faces of the actual target is subdivided into a plurality of electrically independent elementary signal plates in order to reduce the stray capacitance during the sampling of the signal on said plate. According to a preferred arrangement, these elementary plates are oriented in the same way as the scanning lines by the reading electron beam. This reading is performed either by a single beam or by a certain number of independent beams each covering a portion of the target.The applications are the same as in the prior art and in particular to infrared photography.
