چکیده

Existing subsurface scattering rendering algorithms try to reproduce the phenomenon aiming at physically accurate results. Recent research has demonstrated that in some scenarios, to make some assumptions about the way we perceive translucency helps us speeding up calculus achieving real-time results. In this paper we present a new algorithm based on previous perceptual studies general enough to work with measured and user-de ned data. The results obtained make the algorithm interesting in scenarios were a plausible appearance of translucency is enough.

Screen-Space Subsurface Scattering, A Real-time Implementation Using Direct3D 11.1 Rendering API

Context. Subsurface scattering the e ect of light scattering within a material. Lots of materials on earth possess translucent properties. It is therefore an important factor to consider when trying to render realistic images. Historically the e ect has been used for o ine rendering with ray tracers, but is now considered a real-time rendering technique and is done based on approximations o pre...

Efficient Rendering of Local Subsurface Scattering

A novel approach is presented to efficiently render local subsurface scattering effects. We introduce an importance sampling scheme for a practical subsurface scattering model. It leads to a simple and efficient rendering algorithm, which operates in image-space, and which is even amenable for implementation on graphics hardware. We demonstrate the applicability of our technique to the problem ...

Subsurface Scattering in Point-Based Rendering

Point-based graphics has gained much attention as an alternative to polygon-based approaches because of its simplicity and flexibility. However, current point-based techniques do not provide a sufficient rendering quality for translucent materials such as human skin. In this paper, we propose a point-based framework with subsurface scattering of light, which is important to create the soft and ...

Real-Time Translucent Rendering Using GPU-based Texture Space Importance Sampling

We present a novel approach for real-time rendering of translucent surfaces. The computation of subsurface scattering is performed by first converting the integration over the 3D model surface into an integration over a 2D texture space and then applying importance sampling based on the irradiance stored in the texture. Such a conversion leads to a feasible GPU implementation and makes real-tim...

A Combined Approach to Subsurface Scattering-Draft

Current techniques for rendering multilayered translucent materials such as skin, marble, jade, and paper can achieve startling realism by modeling subsurface scattering. However, due to performance concerns, all of these techniques require fixing the material properties, including the depth and scattering parameters of each layer, before rendering begins. This makes it impractical to calculate...
