GPU Ray Tracing With GLSL Tracing light rays from a virtual camera into a 3D scene Ray tracing, at its core, is the process of tracing beams of light through some physical 3D space. Light beams (or rays) typically travel in straight lines until they bump into some object.

First there is ray generation: i draw a full screen alligned quad with an ortho projection and generate then ray position in the I've started toying with some (very simple) real time ray tracing on the GPU and i'm having troubles figuring out what space i am in.

Yes, raytracers can use rasterizers to do parallel ray computations, and that's good. But the bulk of the algorithm doesn't fit the needs of a rasterizer. Indeed, now that there are GP-GPU specific languages like OpenCL and CUDA, most of the research time and money is invested in them, not in shoehorning GP-GPU functionality into a rasterizer.

GLSL = Open Graphics Library Shader Language Part of the OpenGL specification Adapted for browsers as WebGL GLSL is a C/C++ flavoured language with more type safety and no recursion; it executes on the GPU GLSL is used to write shader programs, which are used by OpenGL applications to render graphics What is GLSL?

Ray tracing: GLSL vs CUDA/OpenCL. sansan June 16, 2010, 12:09pm #1. Hello everybody! I have been asked to implement an efficient ray tracing algorithm in my app. After some surfing on the web and some thinking I have identified two hardware-accelerated ways to do this: Parallel implementation using CUDA/OpenCL. Implementation based on OpenGL SL.

Apply a little displacement (e.g. a 1/1000 of the smallest voxel size) to I0e by the r unit vector of the ray: I1 = I0e + r/1000. Find the voxel to these I1. This is the next voxel in the sorted list of voxel-ray intersections. Repeat finding I1e then I2 then I2e then I3 etc. until the bounding box is exited. The list of crossed voxels is sorted.
CUDA or GLSL for ray tracing? : opengl - reddit

GLSL was used for GPGPU because there were no tools to use GPU in a different way. Now there is CUDA. CUDA is designed for GPGPU on NVidia (only) videocards. It does require some learning, but it is not bound to rendering pipeline and other things, that will slow you down.
