set too low.Caution: Activating clamping and reducing the multiplier will reduce the maximumresulting image color range.Pixel FilterA pixel filter weights the image samples taken per pixel and therefore controls theantialiasing quality of the rendering. High image filter sizes may result in blurry imageresults.» 0Width: The pixel filter width defines the number of neighboring pixels in width0 taken in account for sampling.» 0Heigh: The pixel filter height defines the number of neighboring pixels in height0 taken in account for sampling.There are 7 different pixel filter available in VRED:» Box Filter: The box filter is the simplest pixel filter. It weights each image sampleequally. A size of 0.5 should be used for this pixel filter.» Triangle Filter: The triangle filter linearly distributes the samples between the variouspixels. It gives decent results and is therefore the default pixel filter in VRED.it should be used with a size of 1.0 independent of screen resolution.» Gaussian Filter: The gaussian filter uses a gaussian function to weight the samples.samples near the center of a pixel receive a larger weight compared to samplesthat are further away from the pixel center. It gives slightly better results comparedto the triangle filter in some situations. A size of 1.0 to 1.2 is recommended.» Mitchell Netravali: The mitchell netravali filter prevents blurring that may occurwhen using box, triangle, gaussian, or bspline filter by sharpening the image. It givesthe highest quality result but may suffer from ringing on hard contrast edges. A sizeof 2.2 is recommended.285
