Get texture created in outside exe in c++ WASM module

Dear ASOBO, dear MSFS developers! First of all - thanks for your efforts in
developing SDK and supporting this community. May I ask You to reveal possible
ways to get textures in WASM module (for next drawing to gauges/panel) created
in an external EXE. Sure, no problem to render any 2D gauges in external exe
module using any of OpenGL/DirectX/Vulcan/GDI+ to some texture/framebuffer.
But is it possible and how to practically get this texture or framebuffer
using nanoVG c++ code within gauge WASM module? And if several ways are
possible - please advise the best one in Your opinion.

Hello @SimGoGo The first question I’d ask would be: what prevents you from
rendering that texture directly in your WASM module rather than trying to pass
it from an external exe to the module? If you are accessing data you can’t
have access to through WASM, I’d say there’s no solution at the moment. You
could technically render this texture to a file and load it in your module but
I doubt it will be efficient. Maybe a better solution will come with the
network API we are working on as it will allow you to pass information between
an external exe and your module. Regards, Sylvain

Thank you for your answer, Sylvain. I am care about performance aspect in this
case. The concept may be different (I mean “heavy” aircraft with very complex
displays in this case): 1. - Calculate aircraft systems in exe with minimum
performance loss - Calculate and draw all displays in exe - Use WASM to
render on panel that predrawed textures (need a way to transfer it from
exe->WASM) 2. - Calculate systems and displays in WASM and render 2D
displays in WASM to panel 3. - Some “Mixed” approach of 1 and 2. So, as WASM
limited with functions/memory/multithreading/performance - do some part of job
in external exe - is a good idea. So, at least All systems and drawing data
may be calculated in exe. But if use WASM for drawing as next step - need
transfer precalculated drawing data for displays (color and positions of
graphic primitives, values and so on) from EXE->WASM. This is not trivial task
to send drawing data flow from one module to another. As I see - Fenix A320
show a mixed way with very good results - most of job executed in exe - and
some - in WASM. So, be good if ASOBO may explain a native or advanced way to
use similar “mixed” approach, at least for heavy drawing purpose. If texture
rendering in external exe with “reading” it in WASM for next panel drawing not
possible - what will be better way to calculate and draw very complex displays
on your opinion, please? I mean without performance loss, for sure.

Hello @SimGoGo Have you actually tried to run your systems in a WASM module
and experienced performance issue you can report? Several studios also have
ported their whole systems (complex ones) to WASM with success so unless you
have experienced some issues already, I’d say you should give it a try and we
will be interested to know and help if you encounter performance issues. If
you want to stick to the external exe, I’d say the best option at the moment
would be a mix where the rendering is done in WASM and you pass the data
needed for it using SimConnect Client Data. But the time you think you gained
by running your logic in an external exe will be lost waiting for the data to
reach the WASM module so don’t expect any miracle. Let us know what solution
you chose in the end and what result you got. Regards, Sylvain

Thank you, Sylvain.
Already done some part of job with WASM only, but look like I need to try both
this ways to determinate better concept. I will inform about result.
