    Abstract: This disclosure relates generally to the field of image processing and, more particularly, to various techniques and animation tools for allowing 2D and 3D graphics rendering and animation infrastructures to be able to dynamically render customized animations—without the need for the customized animations to be explicitly tied to any particular graphical entity. These so-called entity agnostic animations may then be integrated into “mixed” graphical scenes (i.e., scenes with both two-dimensional and three-dimensional components), where they may be: applied to any suitable graphical entity; visualized in real-time by the programmer; edited dynamically by the programmer; and shared across various computing platforms and environments that support the entity agnostic animation tools described herein. The entity agnostic animations created by the techniques described herein may be output directly to the current scene file that a programmer is working on, or they may be output to standalone, reusable entity agnostic animation object files.

    Abstract: Systems, methods and program storage devices are disclosed, which comprise instructions to cause one or more processing units to analyze input images to a texture atlas and determine how each texture should be modified before being stored in the texture atlas to prevent undesirable drawing artifacts. For example, “tileable” images may be identified on a per-edge basis (e.g., by determining whether each edge pixel is above a certain opacity threshold). The tileable images may then be modified, e.g., by extruding a 1-pixel border identical to the outer row of pixels, before being stored in the texture atlas. “Character”-type sprites may also be identified on a per-edge basis (e.g., by determining whether each edge pixel is below the opacity threshold). The character-type sprites may then by modified by adding a single pixel transparent border around the outer rows of pixels before being stored in the texture atlas.

    Abstract: Systems, methods and program storage devices are disclosed, which comprise instructions to cause one or more processing units to dynamically generate refined normal maps for 2D texture maps, e.g., supplied by a programmer or artist. Generally speaking, there are two pertinent properties to keep in balance when generating normal vectors comprising a normal map: “smoothness” and “bumpiness.” The smoothness of the normal vectors is influenced by how many neighboring pixels are involved in the “smoothening” calculation. Incorporating the influence of a greater number of neighboring pixels' values reduces the overall bumpiness of the normal map, as each pixel's value takes weight from those neighboring pixels. Thus, the techniques described herein iteratively: downsample height maps; generate normal maps; scale the normal maps to maintain bumpiness; and blend the generated scaled normal maps with generated normal maps from previous iterations—until the smoothness of the resultant normal map has reached desired levels.

    Abstract translation: 公开了系统，方法和程序存储设备，其包括使一个或多个处理单元动态地生成2D纹理贴图的精细法线贴图的指令，例如由程序员或艺术家提供。 一般来说，当产生包含法线贴图的法向矢量时，有两个相关的属性保持平衡：“平滑度”和“颠簸”。法向矢量的平滑度受“平滑”计算中涉及的相邻像素数量的影响 。 结合更多数量的相邻像素值的影响可减少法线贴图的整体颠簸，因为每个像素的值从这些相邻像素获取权重。 因此，本文描述的技术迭代地：下采样高度图; 生成法线贴图; 缩放法线贴图以保持颠簸; 并将生成的缩放法线图与先前迭代中生成的法线贴图混合，直到得到的法线贴图的平滑度达到期望水平。

    Abstract: Systems, methods, and computer readable media to improve the operation of graphics systems are described. In general, collision avoidance techniques are disclosed that operate even when the agent lacks a priori knowledge of its environment and is, further, agnostic as to whether the environment is two-dimensional (2D) or three-dimensional (3D), whether the obstacles are convex or concave, or whether the obstacles are moving or stationary. More particularly, techniques disclosed herein use simple geometry to identify which edges of which obstacles an agent is most likely to collide. With this known, the direction of an avoidance force is also known. The magnitude of the force may be fixed, based on the agent's maximum acceleration, and modulated by weighting agents
