## [Jitter Camera (Anti-Aliasing)](vkrt_tuto_jitter_cam.md.htm)
|
|
|
|
Anti-aliases the image by accumulating small variations of rays over time.
|
|
|
|
* Random ray direction generation
|
|
* Read/write/accumulate final image
|
|
|
|
|
|
|
|
## [Handle Thousands of Objects](vkrt_tuto_instances.md.htm)
|
|
|
|
The current example allocates memory for each object, each of which has several buffers.
|
|
This shows how to get around Vulkan's limits on the total number of memory allocations by using a memory allocator.
|
|
|
|
* Extend the limit of 4096 memory allocations
|
|
* Using memory allocators: DMA, VMA
|
|
|
|
|
|

|
## [Any Hit Shader (Transparency)](vkrt_tuto_anyhit.md.htm)
|
|
|
|
Implements transparent materials by adding a new shader to the Hit group and using the material
|
|
information to discard hits over time.
|
|
|
|
* Adding anyhit (.ahit) to the ray tracing pipeline
|
|
* Randomly letting the ray hit or not which is making simple transparency
|
|
|
|
|
|
|
|
|
|
## [Reflections](vkrt_tuto_reflection.md.htm)
|
|
|
|
Reflections can be implemented by shooting new rays from the closest hit shader, or by iteratively shooting them from
|
|
the raygen shader. This example shows the limitations and differences of these implementations.
|
|
|
|
* Calling traceRayEXT() from the closest hit shader (recursive)
|
|
* Adding more data to the ray payload to continue the ray from the raygen shader.
|
|
|
|
|
|
|
|
|
|
## [Multiple Closest Hits Shader and Shader Records](vkrt_tuto_manyhits.md.htm)
|
|
|
|
Explains how to add more closest hit shaders, choose which instance uses which shader, and add data per SBT that can be
|
|
retrieved in the shader, and more.
|
|
|
|
* One closest hit shader per object
|
|
* Sharing closest hit shaders for some object
|
|
* Passing shader record to closest hit shader
|
|
|
|
|
|
|
|
|
|
## [Animation](vkrt_tuto_animation.md.htm)
|
|
|
|
This tutorial shows how animating the transformation matrices of the instances (TLAS)
|
|
and animating the vertices of an object (BLAS) in a compute shader, could be done.
|
|
|
|
* Refit of top level acceleration structure
|
|
* Refit of bottom level acceleration structure
|
|
|
|
|
|
|
|
|
|
## [Intersection Shader](vkrt_tuto_intersection.md.html)
|
|
|
|
Adding thousands of implicit primitives and using an intersection shader to render spheres and cubes. The tutorial
|
|
explains what is needed to get procedural hit group working.
|
|
|
|
* Intersection Shader
|
|
* Sphere intersection
|
|
* Axis aligned bounding box intersection
|
|
|
|
|
|
|
|
|
|
|
|
## [Callable Shader](vkrt_tuto_callable.md.html)
|
|
|
|
Replacing if/else by callable shaders. The code to execute the lighting is done in separate callable shaders instead of been part of the code.
|
|
|
|
* Adding multiple callable shaders
|
|
* Calling ExecuteCallableEXT from the closest hit shader
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## [Ray Query](vkrt_tuto_rayquery.md.htm)
|
|
|
|
Invoking ray intersection queries directly from the fragment shader to cast shadow rays.
|
|
|
|
* Ray tracing directly from the fragment shader
|
