From 9b434e50f02f9ec02ce230de9042ce7448bae451 Mon Sep 17 00:00:00 2001 From: ArielG-NV <159081215+ArielG-NV@users.noreply.github.com> Date: Fri, 15 Mar 2024 16:14:32 -0400 Subject: Implement raytracing extension(s); resolves #3560 for GLSL & SPIR-V targets (#3675) The following PR implements raytracing extensions (GLSL_EXT_ray_tracing, GLSL_EXT_ray_query, GLSL_NV_shader_invocation_reorder & GLSL_NV_ray_tracing_motion_blur); for GLSL & SPIR-V targets. Fully implements all functions, built-in variables, & syntax; resolves #3560 for GLSL & SPIR-V Targets. notes of worth: * __rayPayloadFromLocation, __rayAttributeFromLocation, and __rayCallableFromLocation, were added as SPIR-V Intrinsics to refer to location's of raytracing objects in SPIR-V for when using GLSL syntax. --- source/slang/slang-emit-glsl.cpp | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'source/slang/slang-emit-glsl.cpp') diff --git a/source/slang/slang-emit-glsl.cpp b/source/slang/slang-emit-glsl.cpp index d37a6840b..7e5c84533 100644 --- a/source/slang/slang-emit-glsl.cpp +++ b/source/slang/slang-emit-glsl.cpp @@ -2659,10 +2659,18 @@ void GLSLSourceEmitter::emitVarDecorationsImpl(IRInst* varDecl) prefix = toSlice("callableData"); locationValue = getIntVal(decoration->getOperand(0)); break; + case kIROp_VulkanCallablePayloadInDecoration: + prefix = toSlice("callableDataIn"); + locationValue = getIntVal(decoration->getOperand(0)); + break; case kIROp_VulkanRayPayloadDecoration: prefix = toSlice("rayPayload"); locationValue = getIntVal(decoration->getOperand(0)); break; + case kIROp_VulkanRayPayloadInDecoration: + prefix = toSlice("rayPayloadIn"); + locationValue = getIntVal(decoration->getOperand(0)); + break; case kIROp_VulkanHitObjectAttributesDecoration: prefix = toSlice("hitObjectAttribute"); postfix = toSlice("NV"); -- cgit v1.2.3
