As a proposed method, we implemented UDP, hidden surface removal
and parallax to improve the prototype system.
Imagination's Tile-Based Deferred Rendering technology enables on-chip processing of hidden surface removal
and pixel blending.
By doing only what is absolutely necessary, and by keeping as much 3D processing as possible on-chip, PowerVR's combination of Tile Based Rendering, 32-bit True Color, 8 Layer Multitexturing and Hidden Surface Removal
allows maximum performance to be extracted from the available memory bandwidth.
In the recent past polygon clipping is used to render 3D images hidden surface removal
[9, 11] and to procuce high-quality surface details using techniques such as Beam tracing .
Hidden surface removal
is performed prior to filtering, texture mapping and atmospheric effects to avoid unnecessary work on unseen pixels.
This single-slot PCI card delivers very high frame rates for truly immersive game play and serves up fantastic 3D realism through support of perspective-correct anti-aliased texture mapping, pixel-perfect hidden surface removal
, translucency, real time shadows and smooth shading.
Examples ther PowerVR Ready titles not in the Extreme or p hidden surface removal
with a unique method screen resolutions by combining the on-chip 3 ASICs, microprocessors and microcontrollers, 3Dited States (a).
RenderGL uses the 3D capabilities of OpenGL graphics accelerators to handle rendering algorithms such as hidden surface removal
, Z-buffering, shadow calculations and polygon coordinate calculation -- tasks which normally would be handled by the main system processor.
NEC and VideoLogic have dramatically reduced memory bandwidth requirements by replacing the Z-buffer memory and associated bandwidth with on-chip hidden surface removal
The key to this cost reduction and effective AGP use is the PowerVR's on-chip hidden surface removal
and deferred texturing, which require a fraction of the memory bandwidth needed by conventional 3D systems.
