Backward Ray Tracing

  title={Backward Ray Tracing},
  author={Backward Ray Tracing},
Ray tracing has become a very popular method for image synthesis due to its un paralleled exibility and its ability the generate images of high quality and realism Simulation of e ects such as re ection and refraction have been the hallmarks of ray tracing since its introduction With the advent of stochastic ray tracing the range of e ects expanded to include motion blur soft shadows depth of eld and both blurry re ections and translucency A notable omission from the repertoire of ray tracing… Expand
Transparency modeling for mesh object using ray tracing
Some experiments had done to verify if the caustic effect visualized correctly, and to test the influent of refractive index, number of casted ray, light energy and map size toward the caUSTic's appearance. Expand
Adaptive radiosity textures for bidirectional ray tracing
A rendering method designed to provide accurate, general simulation of global illumination for realistic image synthesis, using a three-pass, bidirectional ray tracing algorithm that traces rays from both the lights and the eye. Expand
Pipeline rendering: interaction and realism through hardware-based multi-pass rendering

Photon maps in bidirectional Monte Carlo ray tracing of complex objects
A bidirectional Monte Carlo ray tracing method simulating global illumination in models containing complex objects that do not have to be tessellated, which makes it possible to treat caustics upon such objects without having to parameterize the surface of the objects. Expand
Accelerating Path Tracing by Eye Path Reprojection
This paper shows that this reprojection of an eye path can be implemented efficiently on graphics hardware with only a small overhead and is able to increase the rendering speed by reusing the reprojected paths instead of tracing new paths while maintaining the same quality. Expand

Consideration of all of these factors allows the shader to accurately simulate true reflection, shadows, and refraction, as well as the effects simulated by conventional shaders. Expand
The hemi-cube: a radiosity solution for complex environments
The method provides an accurate representation of the "diffuse" and "ambient" terms found in typical image synthesis algorithms, and extends the radiosity method beyond the bounds previously imposed. Expand
