![img](ray_tracing_gltf/images/vk_ray_tracing_gltf_KHR_2.png) | [glTF Scene](ray_tracing_gltf) <br> Instead of loading separate OBJ objects, the example was modified to load glTF scene files containing multiple objects. This example is not about shading, but using more complex data than OBJ. However, it also shows a basic path tracer implementation. ![img](ray_tracing_gltf/images/vk_ray_tracing_gltf_KHR_2.png) | [glTF Scene](ray_tracing_gltf) <br> Instead of loading separate OBJ objects, the example was modified to load glTF scene files containing multiple objects.

![img](docs/Images/indirect_scissor/intro.png) | [Trace Rays Indirect](ray_tracing_indirect_scissor) <br> Teaches the use of `vkCmdTraceRaysIndirectKHR`, which sources width/height/depth from a buffer. As a use case, we add lanterns to the scene and use a compute shader to calculate scissor rectangles for each of them. ![img](docs/Images/indirect_scissor/intro.png) | [Trace Rays Indirect](ray_tracing_indirect_scissor) <br> Teaches the use of `vkCmdTraceRaysIndirectKHR`, which sources width/height/depth from a buffer.

![img](ray_tracing_ao/images/ray_tracing_ao.png) | [AO Raytracing](ray_tracing_ao) <br> This extension to the tutorial is showing how G-Buffers from the fragment shader, can be used in a compute shader to cast ambient occlusion rays using ray queries ([GLSL_EXT_ray_query](https://github.com/KhronosGroup/GLSL/blob/master/extensions/ext/GLSL_EXT_ray_query.txt)).
