Does extempore "graphics pipeline" still work?

[Extempore]

Hello all

Curiosity only looking at this thread:

 https://groups.google.com/g/extemporelang/c/u7MQ-SXliFg/m/F87ux2-1AQAJ

In the past I have run "~/extempore/examples/external/xtmrender1.xtm"

and got a nice slowly rotating picture of peppino.

Tried it again after updating to MacOS 13.6.4 Ventura and I get  only a black graphics window and no peppino.

Everything seems to load fine intil the final gl_draw_loop

Then I get this repeated error message:

Error setting uniforms! in xtm_draw_mesh: Invalid Value
Error drawing VAO!: Invalid Operation
Error drawing XTMMesh!: Invalid Value
Error drawing XTMMesh!: Invalid Value
Error drawing XTMMesh!: Invalid Value

Error before drawing XTMModel: Invalid Value
Error drawing XTMMesh!: Invalid Value
Error BEFORE drawing XTMMesh!: Invalid Value
error setting tex parameters: Invalid Value
Error setting uniforms! in xtm_draw_mesh: Invalid Value

Does anyone have any suggestions?

Ben says his glfw3.xtm is setup for  GLFW 3.2.1

The latest is  GLFW 3.4

My macbook air has intel chip.

I never used that library, but for me it fails even before that: 

(sys:load "libs/external/glfw3.xtm")

(sys:load "libs/core/scheduler.xtm")

Traceback: 

```

Hello again Michelle

Nice to hear from you.

I'm running through it now ..........

That all goes well to this point. Do you have the most recent extempore v0.89? 

I'm using Visual Studio Code.

All the rest seems OK

Although there are some complaints about "No bones" in Pepino. Don't know if that means anything.

...........................................

Then line 69:

(gl_draw_loop (now) (/ 1.0 30.0))

..................

But THIS TIME IT WORKS!! It is rotating nicely - a bit jumpy

MAYBE I didn't wait long enough last time.

I'll try xtmrender2.xtm and others to see if they work. 

Following Andrew's suggestion I'm looking at Blender which goes nicely so far. I'm not much into graphics

but thought it would be fun to try something.

Michele let me know if you get any better result

Regards

George

Glad to hear it's working for you! 

I'll give it another try over the weekend..
