Feature request: Add functions to retrieve attribute information from programs
Current reflection API is great and is already quite useful. having the ability to query for attribute information such as location, in/out, and type could greatly aid in the porting process from OpenGL to Vulkan. Especially for tools and middleware that parse this information at run-time. Thanks.
Running glslangvalidator with -V -q shows little useful information on attributes:
a_position: offset 0, type 8b51, size 0, index 0, binding -1
a_normal: offset 0, type 8b51, size 0, index 0, binding -1
Being able to get attribute location and dimension information would be very nice to have indeed.
Same thing here, I was really surprised that this didn't work... great tool otherwise...
` Vertex attribute reflection:
vertexNormal: offset 0, type 8b51, size 0, index 0, binding -1, stages 0 vertexTexcoord: offset 0, type 8b50, size 0, index 0, binding -1, stages 0 vertexTangent: offset 0, type 8b51, size 0, index 0, binding -1, stages 0 vertexBitangent: offset 0, type 8b51, size 0, index 0, binding -1, stages 0 vertexPosition: offset 0, type 8b51, size 0, index 0, binding -1, stages 0 `
@chaoticbob is this still needed or is the equivalent functionality available through spirv-reflect?
