Motion Blur Algorithm for Clipped Triangle Rendering
نویسنده
چکیده
The rendering process reduces the 3D geometry to a set of 2D triangles in the image plane. The projection from 3D is standard. The projected triangles are clipped and sorted so that the final collection of triangles in a pixel do not overlap each other. So at frame f , the image plane holds a collection of pixels Pk, k = 1, . . .M , each of which contains a set of 2D nonoverlapping triangles {Tq(f), q = 1 . . . Nk(f)}. We give the triangles a frame dependence because the motion blur process means the geometry moves around in the image plane. Also, the number of triangles in the pixel varies with frame number. The set of all of the triangles from all of the pixels in the image plane will be labelled T (f):

Clip Space Sample Culling for Motion Blur and Defocus Blur
Motion blur and defocus blur are two common visual effects for rendering realistic camera images. This paper presents a novel clip space culling for stochastic rasterization to render motion and defocus blur effects. Our proposed algorithm reduces the sample coverage using the clip space information in camera lens domain (UV) and time domain (T). First, samples outside the camera lens were cull...
متن کاملBackface Culling for Motion Blur and Depth of Field
For triangles with linear vertex motion, common practice is to backface cull a triangle if it is backfacing at both the start and end of the motion. However, this is not conservative. We derive conservative tests that guarantee that a moving triangle is backfacing over an entire time interval and over the area of a lens. In addition, we present tests for the special cases of only motion blur an...
متن کاملESM-Blur: Handling & rendering blur in 3D tracking and augmentation
The contribution of this paper is two-fold. First, we show how to extend the ESM algorithm to handle motion blur in 3D object tracking. ESM is a powerful algorithm for template matching-based tracking, but it can fail under motion blur. We introduce an image formation model that explicitly considers the possibility of blur, and show it results in a generalization of the original ESM algorithm. ...
متن کاملMotion Blur for EWA Surface Splatting
This paper presents a novel framework for elliptical weighted average (EWA) surface splatting with time-varying scenes. We extend the theoretical basis of the original framework by replacing the 2D surface reconstruction filters by 3D kernels which unify the spatial and temporal component of moving objects. Based on the newly derived mathematical framework we introduce a rendering algorithm tha...
متن کاملHardware Architecture for Fast Camera Effects Rendering
Current commercial graphics cards do not offer fast enough special hardware to render camera effects like motion blur or depth of field. Even the pixel shader, which is useful in many rendering algorithms, is unable to support these effects. This paper presents a hardware structure, which provides fast rendering capability for realizing filtering effects, including also depth of field and motio...
