The Demo Room

The ShaderViews demonstration illustrates the image processing capabilities of the programmable shaders available on POWERVR SGX enabled platforms. It includes a variety of different post-processing effects applied to floating windows and frames zooming across the background. A variety of backgrounds are shown, including still photos, 3D scenes rendered-to-texture (Urban, Asia and Space scenes), and dynamically tessellated terrain.<br/><br/>More than 25 different post-processing effects are illustrated include edge detection, procedural deformations & distortion effects (punch, swirl, mirror, twirl, etc.), color matrix operations, blurring, frosted glass, greyscale and sepia filters. This demonstration includes a rolling demo with scrollable windows and a touch menu to select scenes and effects.

OpenGL ES 2.0 Shader Views

The Shader Show demo illustrates the exciting possiblities of programmable shaders. It highlights procedural texturing effects (wood, fire, clouds, polka dots, brickwork, etc.), procedural deformations (wobbling, waves, variable scaling, melting, etc.) and advanced lighting effect (anisotropic, per-pixel bumpmapping, specular effects, cartoon cell shading, etc.). In addition there is environment mapping and fragment shader branching applied to a variety of different static (mask, lobster, bear, statue, sphere, knot, etc.) and vertex skinned objects (monkey, duck, etc.).<br/><br/>This demonstration includes a rolling demo mode with more than 20 different shader effects on-screen at the same time and an interactive mode which allows the user to browse the catalog of effects and objects.

OpenGL ES 2.0 Shader Show

The SailBoat demo is an extension of the Water demo from the POWERVR OpenGL ES 2.0 SDK, and shows high quality water effects rendered on POWERVR SGX. Generating efficient and detailed water effects can add a great deal of realism to programs that utilise real-time graphics. This demo uses techniques based on the use of vertex and fragment shaders to alter the appearance of a given plane to simulate a water effect.

The RealCharacter demo illustrates hardware vertex skinning applied to a collection of male and female characters with variable level of detail from high (5000 Triangles and 42 Bones) to low (550 Triangles and 25 Bones), advanced per-pixel lighting is used for maximal realism and detail including a base texture layer, normal map and a per-pixel specular map. Ultimate realism is achieved through the usage of high quality motion-capture data, optimised and exported using the POWERVR SDK Toolset, combined with the implementation of real-time soft shadows based on industry-standard shadow mapping algorithms.

$ExtremeBall is a joint project between Digital Legends Entertainment and Imagination Technologies. The demo aims to push current generation hardware to new limits and show features hitherto only seen on high-end games consoles or desktop PCs. The focus is on showing how advanced OpenGL ES 2.0 shaders can dramatically increase the visual quality of mobile graphics.<br/><br/>Among the advanced effects demonstrated here are water shaders complete with refraction and radiosity, multiple levels of detail for each shader, as well as motion captured animation with mesh deformation skinning to support it. The polygon throughput is in excess of 1 million triangles per second.<br/><br/>Hopefully this showcase will inspire mobile developers to further push the incredibly powerful POWERVR SGX hardware, which is found in a long list of top of the range smartphones from all the major OEMs as well as UMPCs, MIDs, STB/DTVs and many other consumer electronics products.$
