Hardware Architecture for Fast Camera Effects Rendering
نویسنده
چکیده
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 motion blur.

An Image-Based Model for Realistic Lens Systems in Interactive Computer Graphics
Many applications, such as realistic rendering, virtual and augmented reality, and virtual studios, require an accurate simulation of real lens and camera systems at interactive rates, including depth of field and geometric aberrations, in particular distortions. Unfortunately, camera models used in Computer Graphics are either too simple to describe these effects or too expensive to simulate f...
متن کاملStandalone Distributed Rendering For Supercomputers
We present a method for rendering large distributed meshes on large distributed architectures that lack traditional graphics rendering capabilites and hardware. This method renders each distributed portion of the mesh independently on an individual process into a depth-buffer and image-buffer. After individual renderings are taken, the Message Passing Interface is used to merge the individual r...
متن کاملFast Incident Light Field Acquisition and Rendering
We present a practical and inexpensive approach for the acquisition and rendering of static incident light fields. Incident light fields can be used for lighting virtual scenes or to insert virtual objects into real world video footage. The virtual objects are correctly lit and cast shadows in the same way as real objects in the scene. We propose to use an inexpensive planar mirror and a high d...
متن کاملDepth of Field Simulation in Computer Graphics
A major part of the amount of realism in a rendering engine is the engine's camera model. Simulating real camera models can produce desired realistic effects such as depth of field (DOF). Several methods are currently used to simulate DOF but they are either computationally expensive methods that produce realistic results or inaccurate but fast methods. This paper includes a list of reasons beh...
