The graphics pipeline takes geometric data representing an object or scene ( typically .... Most lighting and other shading computations involve quantities such as ...

In graphics, this can be done by rendering the z-values for all objects first, before shading. For general-purpose computation, the z-cull unit can be used to select ...

Jul 13, 2009 ... Geometric complexity—how many objects are visible and how detailed ... processing for the vertex- and pixel-shading units, then generalizing those to be ... occlusion information, yet minimally increases computation cost.

Apr 20, 2011 ... Broadly, this type of language is called a shading language. ... recipe for how to render an object by using programmable graphics hardware. ... In such a model, computation occurs in response to data that flows through a ...

Vegetation Procedural Animation and Shading in Crysis ... but also the leaves, in detail, with all computations procedurally and efficiently done on the GPU. ... which is enough for our vegetation case, because it is a single vegetation object.

To compute the tangents in our test case, we use a custom mental ray shader that temporarily overrides the current object's shading and displays the tangents as ...

The SceniX scene management engine is an object-oriented programming ... SceniX takes advantage of modern GPU shading and compute power by fully ...

In this chapter, we discuss one use of object detection: overlaying a tracked object with an image. As you'll see, the computational requirements of this ...

First, we compute the surface shading information by performing various ... Then we loop over each light source that illuminates the object and compute its ...

Typical rendering engines perform all four of these steps at one time when rendering an object in the scene. Deferred shading is a technique that separates the ...
