vk_raytracing_tutorial_KHR VS tinyraytracer

The program is based on iOrange RTX On tutorial and nvidia vk_raytracing_tutorial_KHR.The problem is output image is just whatever color i write on miss shader and no triangle at all.The acceleration structure seems correct like in the image. Any idea why no triangle hit at all?

These code samples should help you get familiar with the vulkan raytracing apis: https://github.com/nvpro-samples/vk_raytracing_tutorial_KHR

I am reading Nvidia's intersection shader tutorial. It shows how to add an intersection shader for ray-sphere-intersection and add it to a new hit group. However, I am using the ray query approach in my project, which means I don't have the ray tracing pipeline. How can I customize an intersection for a bunch of special objects then? I have created AABB BLAS for them but there must be more work to be done in my `while(rayQueryProceedEXT(rayQuery))` loop.

Edit: check this tutorial https://github.com/nvpro-samples/vk_raytracing_tutorial_KHR/tree/master/ray_tracing_intersection

The other option is the main NVIDIA tutorial, https://github.com/nvpro-samples/vk_raytracing_tutorial_KHR, of which I am a co-author. This assumes prior Vulkan experience and takes quite a while to work through; I'm obviously biased but I think there's some worth in still reading this second if you choose to start with the other tutorial.

Tiny raytracer and the related tiny series are pretty good implementations of certain popular rendering techniques, without the use of an API.

For some reason, that reminded me of this.

An excellent starting point for anyone interested in low-level graphics programming is Sokolov’s tinyraytracer [0]. It’s also a great way to learn a new language (work through the code while porting it to $DIFFERENT_LANGUAGE).
