May be a silly question to ask, but if i want to write my own object shaders does it depend on dx11 or opengl backend ?? I mean do i have to write an hlsl or a glsl shader ?
Custom shader are written in glsl and then it is trans-compiled to platform’s own shading language for example for:
Mac/IOS -> MSL,
Windows-> Hlsl/Glsl (DX/OpenGl, depend on api you choose),
Linux -> Glsl/SPIR-V (OpenGl/Vulkan, depend on api you choose)
So, you just have to write shader in glsl and let armory/kha handle platform’s backend.
Ok, that was my understanding of how armory was working but i was not sure. Thanks for clarifying.
I come back to you, do we have access to geometry shader too ?
Yep, we can do whatever kha can do, you can access and use geometry shader too but i haven’t used geometry shader.
I guess i have to investigate what kha can do
Geometry shaders currently only work when targeting GLSL, HLSL support is unfinished. It will never work on Metal though because that simply doesn’t support geometry shaders (which tells you a lot about the general state of geometry shaders which are frowned upon by many developers because of their performance problems (see for example http://www.joshbarczak.com/blog/?p=667)).
Ok, great! thanks for clarify this …
