## Build
- [](https://gitlab.uni-koblenz.de/vulkan2021/vkcv-framework/-/commits/develop)
+Git submodules are used for libraries. To download the submodules either clone using
+`git clone --recurse-submodules` or after `git clone` use `git submodule init` and
+`git submodule update`.

+
+## Documentation
-The documentation concerning the respective merge request is listed here:
-https://vkcv.de/branch/
+A pre-built documentation can be found here:
+https://userpages.uni-koblenz.de/~vkcv/doc/
-It is automatically generated and uploaded using the CI pipeline.
+But it is recommended to build the documentation with Doxygen locally to get the most recent
+changes. There is also an optional CMake target to build the documentation via Doxygen.

+## How to build with Clang on Linux
+
+Just follow the steps of "How to build on YOUR DISTRO" but replace `gcc` with `clang` and `g++` with `clang++`.
+This should work actually but maybe the names of the packages are a little different. So look at your official
+repository for the packages and their names if it doesn't work.

+# Bindless textures
+An example project to show usage of bindless descriptor indexing with the VkCV framework
+
+
+
+## Details
+
+The project utilizes a Vulkan extension to access an array of descriptors with arbitrary size. The
+size does not need to be known during shader compilation and can be adjusted during runtime when
+creating the graphics pipeline.
+
+## Extensions
+
+Here is a list of the used extensions:
+
+ - [VK_EXT_descriptor_indexing](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_EXT_descriptor_indexing.html)

+# Fire works
+An example project to show a particle simulation via compute shader to visualize virtual firework
+
+
+
+## Details
+
+The project uses many different compute shaders to calculate different steps of the particles
+lifecycle. Particles can dynamically be spread to different events for explosions on the GPU. The
+particles will then be rendered as volumetric smoke and geometric smoke using geometry shader
+invocations.

+# First mesh
+An example project to show a simple mesh can be rendered with the VkCV framework
+
+
+
+## Details
+
+This project is rather a proof of concept to show that rendering a more complex mesh than a single
+triangle was indeed possible with the given API. It was used as a benchmark for further API design
+changes.

+# First scene
+An example project to show a whole scene can be rendered with the VkCV framework
+
+
+
+## Details
+
+Similar to the projects to show rendering a single triangle or a simple mesh was possible. This
+project shows that a whole scene can easily be loaded from any GLTF file and be rendered using the
+modules from the VkCV framework.

+# Head demo
+An example project to show how the VkCV framework could be used for medical applications
+
+
+
+## Details
+
+This project renders a mesh from a human skull by [HannahNewey](https://sketchfab.com/HannahNewey)
+and splits the rendering on three axes into diffusive shading and drawing the vertices as point
+cloud. In a similar way you could visualize different layers of a human body to make a specific
+part the visual focus without blending the layers above completely away.

+# Indirect dispatch
+An example project to show usage of indirect compute shader dispatching
+
+
+
+## Details
+
+The project shows off indirect dispatching of compute shaders for an implementation of motion
+blur. Additionally, the calculated motion vectors for the motion blur can be used for temporal
+upscaling techniques such as FSR2.

+# Indirect draw
+An example project to show usage of indirect draw calls
+
+
+
+## Details
+
+The project utilizes multiple Vulkan extensions to access to make indirect draw calls which can be
+modified on the GPU from within compute shaders. This will be used to cull the rendered scene on
+the GPU instead of (potentially) more expensive frustum culling on the CPU.
+
+## Extensions
+
+Here is a list of the used extensions:
+
+ - [VK_KHR_shader_draw_parameters](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_shader_draw_parameters.html)
+ - [VK_EXT_descriptor_indexing](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_EXT_descriptor_indexing.html)

+# Mesh shader
+An example project to show usage of mesh shaders with the VkCV framework
+
+
+
+## Details
+
+The project utilizes a Vulkan extension to use hardware accelerated mesh shaders. Those mesh
+shaders can replace the usual vertex-, tessellation- and geometry-shader stages in the graphics
+pipeline. They also act more similar to compute shaders.
+
+The application uses those mesh shaders to cull a rendered mesh into individual groups of triangles
+which are called meshlets in this context.
+
+The project currently uses the Nvidia GPU exclusive extension for mesh shading but it could be
+adjusted to use the cross compatible extension
+"[VK_EXT_mesh_shader](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_EXT_mesh_shader.html)"
+instead.
+
+## Extensions
+
+Here is a list of the used extensions:
+

+# MPM
+An example project to show the implementation of an MPM soft-body simulation with the VkCV framework
+
+
+
+## Details
+
+The project shows off an example implementation of an MPM simulation which are widely used
+in computer graphics to simulate the behavior of solids, liquids or gases. It utilizes the discrete
+representation of objects as combined particles as well as a discrete grid of data. Together both
+representations help to stabilize the result while providing as much detail as possible.

+# Particle simulation
+An example project to show thousands of particles can be simulated with the VkCV framework
+
+
+
+
+
+## Details
+
+Similar to the projects to show rendering a single triangle or a simple mesh was possible. This
+project shows that many particles can be simulated using compute shaders and rendered using the
+usual graphics pipeline, all with the VkCV framework.
+
+The behavior of the particles can easily be adjusted loading a different compute shader. That is
+the reason the application can be started with three different pipelines using one of those
+parameters:
+
+ - `--space` to simulate particles flying around in a wild way through space
+ - `--water` to simulate particles dropping down like a waterfall to the ground
+ - `--gravity` to simulate particles being drawn by points of gravity in space flying around those points

+# Path tracer
+An example project to show the implementation of a path tracer with the VkCV framework
+
+
+
+## Details
+
+The project shows off an example implementation of a path tracer using compute shaders to render
+a physically plausible image given an artificial subset of materials. The path tracer uses a
+converging technique to reduce the noise of the image iteratively.

+# Ray tracer
+An example project to show the implementation of a ray tracer with the VkCV framework
+
+
+
+## Details
+
+The project shows off an example implementation of a ray tracer using compute shaders to render
+an image containing abstract geometry and materials with different properties. The ray tracer
+limits the maximal depth to allow highly detailed reflections without getting too slow for
+realtime use.

+# RTX ambient occlusion
+An example project to show usage of hardware accelerated ray tracing with the VkCV framework
+
+
+
+## Details
+
+The project utilizes multiple Vulkan extensions to make use of hardware accelerated ray tracing.
+Newer GPU architectures provide special hardware to allow the use of acceleration structures and
+ray tracing pipelines. This application uses those features to render an implementation of
+ambient occlusion in realtime.
+
+## Extensions
+
+Here is a list of the used extensions:
+
+- [VK_KHR_get_physical_device_properties2](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_get_physical_device_properties2.html)
+- [VK_KHR_maintenance3](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_maintenance3.html)
+- [VK_KHR_deferred_host_operations](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_deferred_host_operations.html)
+- [VK_KHR_spirv_1_4](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_spirv_1_4.html)
+- [VK_KHR_pipeline_library](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_pipeline_library.html)
+- [VK_EXT_descriptor_indexing](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_EXT_descriptor_indexing.html)
+- [VK_KHR_buffer_device_address](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_buffer_device_address.html)
+- [VK_KHR_acceleration_structure](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_acceleration_structure.html)

+# SPH
+An example project to show the implementation of an SPH fluid simulation with the VkCV framework
+
+
+
+## Details
+
+The project shows off an example implementation of an SPH fluid simulation which are widely used
+in computer graphics to simulate the behavior of fluids with a discrete amount of particles. The
+implementation is able to run in realtime allowing interactive use.

+# Voxelization
+An example project to show a volumetric global illumination technique with the VkCV framework
+
+
+
+## Details
+
+The project utilizes multiple Vulkan extensions (some of them optionally) to implement multiple
+graphics effects in an advanced visualization of a whole scene. Together this brings visual
+features like shadow maps, indirect lighting via discrete voxels and multiple post-processing
+effects like bloom and lens-flares to the screen. To make all of this available in realtime even
+on low powered hardware, it is possible to utilize multiple different upscaling methods.
+
+## Extensions
+
+Here is a list of the used extensions:
+
+- [VK_EXT_descriptor_indexing](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_EXT_descriptor_indexing.html)
+- [VK_KHR_shader_subgroup_extended_types](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_shader_subgroup_extended_types.html)
+- [VK_KHR_shader_float16_int8](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_shader_float16_int8.html)
+- [VK_KHR_16bit_storage](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VK_KHR_16bit_storage.html)
