How to do ray tracing in modern OpenGL? - Stack Overflow

    https://stackoverflow.com/questions/3667218/how-to-do-ray-tracing-in-modern-opengl
    Opengl and glsl can be used for both ray and path tracing if you are really good at it. however there are few other better options like Nvidia optix with Cuda toolkit, directx 12, vulkan ray tracing, metal, falcor. Note that, all these are low level APIs that could be good performance with Nvidia recent rtx technology and support multi gpus

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 is not for raytracing. (Pedants here might say you can, but that's probably not how they want you do to your homework assignment.) 9. level 2. Zeliss. · 6y. When I took my graphics courses a few years ago, we had a graphics homework assignment which was to implement a ray-tracer using a fullscreen quad and a fragment shader. It's not ...

    The steps in the tutorial are: Step 1 - Create a simple scene graph. Step 2 - Using an Alternative Renderer. Step 3 - Examining COpenGLRender. Step 4 - Ray Trace Mode and Menu. Step 5 - Create An Image to Render To. Step 6 - Display the Ray Trace Image. Step 7 - Create a Renderer Class.

My Ray Tracing Tutorial : opengl

    https://www.reddit.com/r/opengl/comments/hnzhej/my_ray_tracing_tutorial/
    The first series covers building a simple ray tracer in GLSL. I just stumbled upon this reddit group and decided to share it with you. I hope some of you will find it useful, that would make me super happy. Currently, there are 4 parts, covering basic sphere-ray intersection, directional and point light, Phong shading, and reflections.

Speed of ray tracing compared to e.g. OpenGL (or other …

    Even if implemented in software, a rasterizer like OpenGL can be blazingly fast, quite easily. The rendering complexity with rasterizers mostly depends on the amount of input geometry. Since everything happens locally (= one triangle at a time) it's also quite cache friendly. Raytracing is a global rendering model.

3D C/C++ tutorials - Ray tracing

    http://3dcpptutorials.sk/index.php?id=16
    To compile and run these tutorials some or all of these libraries are required: FreeImage 3.16.0, GLEW 1.11.0, GLUT 3.7.6 / GLUT for Dev-C++, GLM 0.9.5.4. Ray tracing algorithm generates an image by tracing the path of light through pixels in an image plane. It is capable of producing a very high degree of visual realism, but at a greater ...
