I heavily depended on https://github.com/MarioSieg/BGFX_Noesis_Renderer/tree/main and https://github.com/Dakror/noesis-bgfx/tree/master but tried to remove their in-house features (convert to plug and play). Later worked from https://github.com/kuncarous/nextmu/tree/main as well.
https://github.com/kuncarous/nextmu/tree/main is probably a better implementation and I would recommend using his stuff if this doesn't work.
Example is a conversion of this project https://github.com/Noesis/Tutorials/tree/master/Samples/IntegrationGLUT You can press F1 to view debug information. No idea if it's useful though.
Here's an example of the intended output (The mouse click artifacts aren't actually there): https://i.imgur.com/x76BcOz.gif
If you're trying to get this to work first make sure that BGFXRenderDevice/Src/Shaders/build_shaders.bat is ran before the program to compile the shaders.
You may want to remove BGFXRenderDeviceApi.hpp when compiling. I had linker problems with this file in a different project and I really have no idea what it does but the official Noesis examples have a similar file so I added it anyway.
If the program crashes immediately hopefully the issue is just you're compiling to the wrong shader language.
Change --profile s_5_0 to whatever is more appropriate. Use the debugger to check what bgfx::getRendererType() is set to. Probably metal on MacOS and spirv on Linux.
Possible profiles:
100_es OpenGL ES Shading Language / WebGL (ESSL)
300_es
310_es
320_es
s_3_0 High-Level Shading Language (HLSL)
s_4_0
s_5_0
metal Metal Shading Language (MSL)
pssl PlayStation Shader Language (PSSL)
spirv Standard Portable Intermediate Representation - V (SPIR-V)
spirv10-10
spirv13-11
spirv14-11
spirv15-12
spirv16-13
120 OpenGL Shading Language (GLSL)
130
140
150
330
400
410
420
430
440
If the program still crashes then idk lol.
This project was made in CLion on windows. I use vcpkg for bgfx, glfw3 and glm. There are other packages in vcpkg.json. No idea why; they might be needed.
NoesisGUI is installed in C:/dev/NoesisGUI
