What Is an OpenGL® Shadow? (with picture) - EasyTechJunkie
https://www.easytechjunkie.com/what-is-an-opengl-shadow.htm
This means real-time ray tracing, although it would accurately render shadows, usually is not practical. Another method that can be used to create an OpenGL® shadow is known as shadow mapping. This method uses the depth or stencil buffer to render a scene from the angle of the light source as a series of distances from the light source to the surfaces of …

Ray tracing with OpenGL Compute Shaders (Part I)
https://blog.lwjgl.org/ray-tracing-with-opengl-compute-shaders-part-i/
Dec 8, 2014 • 1 min read. An excellent first part article/tutorial of a series on 'Ray tracing with OpenGL Compute Shaders' by Kai Burjack. Its pretty rare to find good tutorials covering such topics especially using modern OpenGL techniques. By the end of the tutorial series its expected that you'll be able to produce cool results like the ...
opengl - Problems implementing a screen space shadow ray …
https://gamedev.stackexchange.com/questions/44758/problems-implementing-a-screen-space-shadow-ray-tracing-shader
The idea is to calculate the view coordinates of pixels and cast a ray to the light. The ray is then traced pixel by pixel to the light and its depth is compared with the depth at the pixel. If a pixel is in front of the ray, a shadow is casted at the original pixel.

Ray traced hard shadows for OpenGL using Vulkan RTX and Windows memory handles. Requirements. C++ 17; GPU support for: gl_ext_memory_object_win32; vk_nv_ray_tracing; How does it work? Scatter is a small Vulkan library that produces a screen space shadow texture based on a single directional light. As for now, the technique is 1spp hard shadows.
Implementing soft shadows in a ray tracer - Stack Overflow
https://stackoverflow.com/questions/31658226/implementing-soft-shadows-in-a-ray-tracer
Show activity on this post. what I am trying to do is implementing soft shadows in my simple ray tracer, developed in C++. The idea behind this, if I understood correctly, is to shoot multiple rays towards the light, instead of a single ray towards the center of the light, and average the results. The rays are therefore shot in different ...
