bcrt VS vk_raytracing_tutorial_KHR

I with the sport of writing business card code would catch on more. It's a compelling format. I can't resist mentioning my own efforts in this category, https://github.com/2bt/bcrt.

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.
