Abstract
A method and system measuring the correctness of rendered images. A reference renderer generates a reference image from data describing the image. A tolerance buffer is generated that includes a tolerance for a pixel representing a portion of the reference image. If a renderer renders the pixel outside the tolerance for the pixel, the renderer is deemed to have rendered the pixel incorrectly. If the renderer renders the pixel within the tolerance, the renderer is deemed to have rendered the pixel correctly.
Claims31
A computer-readable medium having computer-executable instructions, comprising:
- generating a reference buffer from data associated with an image, the reference buffer having a value associated with a pixel representing a portion of the image;
- generating a tolerance buffer that includes a tolerance value that indicates a tolerance for the pixel;
- generating a rendered buffer from the data associated with the image, the rendered buffer having a value associated with the pixel;
- and
- determining whether the value of the render buffer that is associated with the pixel is outside the tolerance value for the pixel.
A method, comprising:
- generating a reference buffer from data associated with an image representable by pixels, the reference buffer including a value associated with each pixel;
- in conjunction with changing a value in the reference buffer, changing a corresponding value in a tolerance buffer, wherein each value in the tolerance buffer comprises a tolerance for rendering a pixel associated therewith.
A system, comprising:
- a reference renderer arranged to render a pixel representing a portion of a reference image based on data associated with the image;
- and
- a tolerance buffer arranged to include a tolerance to determine correctness in rendering the pixel.
