Making it easier to work with shaders https://git.yummers.dev/slang.git/atom?h=master 2018-06-28T18:14:48+00:00 2018-06-28T18:14:48+00:00 Tim Foley tfoleyNV@users.noreply.github.com 2018-06-28T18:14:48+00:00 urn:sha1:dfe13b54286b27dd15f591455bbb86b7798285c2 The `render-test` project has an in-progress graphics API abstraction layer, and it makes sense to share this code with our examples rather than write a bunch of redundant code between examples and tests. Most of this change is just moving files from `tools/render-test/*` to a new library project at `tools/slang-graphics/`. The most complicated code change there is renaming from `render_test` to `slang_graphics`. The existing `hello` example was ported to use the graphics API layer instead of raw D3D11 API calls. It is still hard-coded to use the D3D11 back-end and the `SLANG_DXBC` target, so more work is needed if we want to actually support multiple APIs in the examples. I also went ahead and implemented an extremely rudimentary set of APIs to abstract over the Windows platform calls that were being made in the example, so that we could potentially run that same example on other platforms. I did *not* port `render-test` to use those APIs, and I also did not implement them for anything but Windows (my assumption is that for most other platforms we would just use SDL2, and require people to ensure it is installed to their machine before building Slang examples). 2018-06-22T17:09:01+00:00 jsmall-nvidia jsmall@nvidia.com 2018-06-22T17:09:01+00:00 urn:sha1:d0c9571be3a2167a9f019310aca8f7cd326972c0 * Added Result definitions to the slang.h * Removed slang-result.h and added slang-com-helper.h * Move slang-com-ptr.h to be publically available. * Add SLANG_IUNKNOWN macros to simplify implementing interfaces. Use the SLANG_IUNKNOWN macros to in slang.c * Removed slang-defines.h added outstanding defines to slang.h 2018-05-03T18:25:13+00:00 jsmall-nvidia jsmall@nvidia.com 2018-05-03T18:25:13+00:00 urn:sha1:367f3a78a40731da45ee12b9a18c94707f1d1429 * First pass at InputLayout for Vulkan Add support for RGBA_Float32 * Use VulkanModule and VulkanApi to handle accessing Vulkan types. * First pass at Vulkan swap chain/Device queue. * Added VulkanUtil for generic function functions. * Move more functionality to VulkanApi and VulkanUtil. Make Buffer able to initialize itself. * More tidy up around VulkanDeviceQueue * First pass use of VulkanDeviceQueue in VkRenderer * First pass use of VulkanSwapChain on VkRenderer * Added depth formats. Binding for constant and vertex buffers for Vulkan. * Setting up VkImageView on backbuffers. * First pass support for setting up vkRenderPass. * Fixes to work around Vulkan swap chain/verification issues. * Added support for Pipeline and a pipeline cache. * Working without waiting - because use of pipeline cache. * Added support for VkFramebuffer in Vulkan. * First pass at creating Vulkan graphics pipeline. * More efforts to get Vulkan to render. * Small improvement for checking of Binding flags. * Removed setConstantBuffers from the Renderer interface - so that all resource binding takes place through the BindingState. To make this work required a 'hack' in render-test main.cpp - so that the constant buffer binding that is needed in some tests is only added when it doesn't clash. * RendererID -> unified into RendererType. Added getRendererType to Renderer interface. Added ProjectionStyle, and function to get from RendererType. Added getIdentityProjection to RendererUtil - to get projection that is the 'identity' - but hits the same pixels for all projection styles. * Fix build problem on Win32 on Vulkan where should use VK_NULL_HANDLE. * Improve naming, comments. Remove dead code. * Remove unwanted comment.
