VCT is a way to apply indirect lighting to a scene to approximate Global Illumination. GI helps increase the realism of a given scene. Paper Blog
Light Propagation Volumes
Light propagation volumes is a technique to approximately achieve global illumination (GI) in Real-time.It uses lattices and spherical harmonics (SH) to represent the spatial and angular distribution of light in the scene Paper Blog
Post Processing Effects
Yume Engine has rich post processing effects such as Depth of Field,SSAO,Bloom,Auto Exposure and Godrays.It is really easy to implement/try new post process effects with the render call driven renderer.
Horizon Based Ambient Occlusion
Adapting from the sample in NVidia SDK’s DirectX 9 HBAO implementation, Yume Engine supports HBAO. Ambient Occlusion is not a simple concept to explain but in easiest words… Paper
Since Yume is fully deferred,there has to be a way to implement lights.In a deferred pipeline,we must create a pass for each light,be it directional, point or spot light. For each point light,we draw a tesellated sphere,move it to lights Blog
Scaleable Ambient Obscurance
Scaleable Ambient Obscurance is really easy to implement and very light on the performance side.In the implementation… Paper Blog
There is a way to achieve light shafts/god rays/light beams without too much of a work.As described in GPU GEMS god rays can be achieved with a simple trick.It wont be very accurate but we’ll get results The “shaft” effect comes from the second pass,blur passes and tonemapping is not necessary but it looks good.The math behind the effect is explained in the Gpu Gems 3 papers so if you want to check it out its free.
