XLIGHTS Angle?

[Juddge]

what is the difference between the xlights download and the xlights_ANGLE edition ?
does anyone know ?

 

[fugley]

never heard of it altho if you google it google will point you to this forum for the anwser ... maybe seach here

Related to porting to iPadOS perhaps?

 

[Katekate]

where are you seeing that?

They're building an ANGLE rendering variant of xLights. Instead of native GL drivers it uses ANGLE (OpenGL ES 3.0 translated to Direct3D 11 on Windows, Vulkan on Linux). https://en.wikipedia.org/wiki/ANGLE_(software)

You cannot do both old and new way in the same binary so there are 2 binaries.

so it will be more useful in the future for windows pcs as the 3d graphics card will be utilised properly for rendering

Scott just removed all the ANGLE stuff, so ignore it. We don't really have OpenGL on the iPad so we added support for ANGLE for the Shader effect (all ui is Metal, so not needed there), but the performance of ANGLE was horrible for our use case. Thus, over the last several days, I moved the ShaderEffect from using ANGLE/OpenGL to using gslang -> spirv -> metal directly. This is actually slightly faster than OpenGL on Mac, WAY faster than ANGLE on iPad.

We also now have a complete Vulkan accelerated render engine for Windows and Linux. On Linux, the same gslang -> spirv can be used for the shader as Vulcan uses the spirv directly. Scott is working on the same for the Vulkan on Windows use case.

In any case, ANGLE on Windows was more or less an experiment that is now irrelevant. The path we are going is Vulkan on Linux and Windows and Metal on Mac/iPad.

excellent thankyou for the explanation, if it was going to be used for FPP advancement i was going to use it for testing to assist
