Raytracing | OGRE - Open Source 3D Graphics Engine
https://www.ogre3d.org/tag/raytracing
Over the last couple months we have been working on Voxel Cone Tracing (VCT), a Global Illumination solution. Voxel Cone Tracing could be seen as an approximated version of ray marching. The scene is voxelized and three voxels are generated, containing albedo, normals and emissive properties. In other words, we build a Minecraft-looking ...

Re: Ray tracing support for Ogre 2.2+. Post. by dark_sylinc » Wed Jan 27, 2021 3:58 pm. Your approach requires 2 rays per pixel: 1 from camera to pixel + 1 from pixel to light source. That is wasteul: You already know the pixel's location from the rasterization pass (see inPs.pos which is in view space). You can:

Voxel Cone Tracing is similar to Ray Marching in the sense that we trace a few rays, and march across them until we hit obstacles. But instead of sending hundreds of rays, we only trace 4 to 6 ‘rays’ (called cones) and use 3D …

A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects. This can be converted to a point in space by calling getPoint (). Definition at line 112 of file OgreRay.h. References Ogre::Math::intersects ().

Ogre is a realtime rendering engine. Many of the pictures on cgtalk and other sites are rendered offline or slowly, often with ray tracing. The technology of the two are fundamentally different. One can make offline rendered pictures as detailed …
How does ogre raytracing for gpu_laser work? - Gazebo: Q&A Forum
https://answers.gazebosim.org/question/20200/how-does-ogre-raytracing-for-gpu_laser-work/
Thanks! I studied the interface a bit more and came to the conclusion that Ogre don't use ray tracing, but a different technique. (For me) It looks like that they create a special kind of texture for the rendering of depth data. The actual data a stored as RGB in a float array (R is range, G is ???, B is Intensity).

Ogre offers various GI techniques and it can be overwhelming which one to choose.. Ambient Lighting. The simplest and fastest solution there is. It can be: Flat. Use SceneManager::setAmbientLight and set upperHemisphere and lowerHemisphere to the same value or set HlmsPbs::setAmbientLightMode to AmbientFixed.. This is just a solid colour …
