Probably someone should take on this, I can’t I don’t have proper opencl support, but if someone wants to make a port, please save the original code (so that it continues to work on old systems) and through ifdef or through other mechanisms add work on modern systems.

@anzhi0708 If you have opencl support in your system and want to make this demo work, then I think everyone will be happy if you make it work. ^.^

blogdron commented 3 years ago

for fast fix add #define CL_USE_DEPRECATED_OPENCL_1_2_APIS in Corange/demos/metaballs/include/kernel.h after #define CL_USE_DEPRECATED_OPENCL_1_1_APIS and build again

try and please report me ))

I would like to fix this by myself very much but unfortunately I'm only 16 and barely know anything about CS, sad... I'm using Linux Mint and the CPU is Intel(R) Core(TM) i5-5350U CPU @ 1.80GHz, OS Linux Ulyana 5.4.0-53-generic #59-Ubuntu SMP Wed Oct 21 09:38:44 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

You probably don't have software support, unfortunately I can't help here. Maybe someone else will come here and tell you what is needed to solve the problem.

I add in Corange/demos/metaballs/include/kernel.h defines

#define CL_TARGET_OPENCL_VERSION 220 
#define CL_USE_DEPRECATED_OPENCL_1_1_APIS
#define CL_USE_DEPRECATED_OPENCL_1_2_APIS

So it is probably not enough to simply specify permission to use the deprecated API, but rather explicitly fix the code. Here I am also powerless because I do not have the necessary support in the hardware and I cannot check the work.

Here I myself do not understand it is written that the default version is 220, but clinfo reports that only the 110 version is supported. I have no experience with this, but it looks strange.

I'm only 16

Great, you have good interests. But since you have little experience, and I have no opportunity, then we will just leave this issue for now, maybe someone will read about the problem and try to solve it with the right hardware and skills and then offer a patch.

You can check other demos, they are interesting too :)

If something also does not work or is incomprehensible, let us know it will be useful for everyone.

...

Although it is not a fact that someone will take on corrections :smile: : ))))

@fedor-elizarov Thanks a lot man, appreciate your help, I love you :3 Appreciate you guys' work! Very cool! ^_^

blogdron commented 3 years ago

@anzhi0708 Okay :D Maybe someone can figure out the problem. The error is somewhere in the code, and probably all in the context initialization. Okay, good luck. Dig into the code it's interesting Corange is basically a project for fun and experimentation. Don't close this issue. All the best.

Sorry to join to this thread one year later :disappointed:. I'm on Linux and have problems compiling the demo "metaballs" too.

I've solved the openCL issue just by defining -D"CL_TARGET_OPENCL_VERSION=120". Well, almost... On Linux I'm using the following command to compile "metaballs":

gcc -O3 -fno-pie -no-pie -DNDEBUG -D_NDEBUG -D"CL_TARGET_OPENCL_VERSION=120" ./src/*.c -I./include -I../../include -std=gnu99 -Wall -Werror -Wno-unused -L../../ -Wl,-rpath,../.. -lcorange -lGL -lSDL2 -lSDL2_net -lSDL2_mixer -lOpenCL -lm -o metaballs

(Note that here using rpath I've hard-coded the path of corange.so to ../.. for convenience).

I had a first issue about metaballs/kernels/particle.cl line 41: that was easy to fix this way:

      velocities[i].xyz = velocities[i].xyz * 0.75;  // error
      velocities[i].xyz = velocities[i].xyz * 0.75f; // correct!

But then I've found an unsolvable issue in: https://github.com/orangeduck/Corange/blob/9a7372d660dc469965297aea6935a85279a7b6f7/demos/metaballs/assets/podium/podium.mat#L1 because I get:

[ERROR] (src/casset.c:asset_hndl_ptr:182) Failed to get Asset '/.../Corange/assets_core/shaders/forward', is it loaded yet?

There is no Corange/assets_core/forward directory...

Not sure what I can do to replace it...

[Edit] If I replace Corange/demos/metaballs/assets/podium with Corange/demos/rendering/assets/podium it compiles and run, but... I just see something dark with some tiny particles inside, like in this screenshot:

I suppose that something in my settings is wrong (maybe my OpenCL configuration).

Nevermind. The other demos work perfectly. Thanks for making and sharing this engine :smiley:

@CORANGE is path to Corange/assets_core/ yes assets_core/shaders not have forward directory. forvard is OOOOLDD renderer is deprecated you can see him in old commits https://github.com/orangeduck/Corange/tree/e1a6688e1d0e6870f5a434ef878572f52ad2a8c9/core_assets/shaders

for current engine need replace forward to deferred in all *.mat files 

-$CORANGE/shaders/forward/static.vs
+$CORANGE/shaders/deferred/static.vs

Unfortunately I have a very old video card and I don't have OpenCL support so I just can't build the metaspheres. And check if anything works

But that's not all, you need to make a full-fledged transfer there, many paths are not correct. You need to port. There is clearly old code / configuration

Thanks for your quick feedback.

Basically even after having copied the old files (and re-addressed their references), the best I could get was the same output I already got in the last screenshot I posted above.

However, by looking at metaballs.c, I've seen two extra definitions: -D"VOLUME_RENDERER" -D"MARCHING_CUBES". If I compile using both (or just MARCHING_CUBES), I get an OpenCL error:

[...]
[DEBUG] (src/casset.c:file_load:282) Loading: '/.../Corange/assets_core/fonts/console_font.fnt'
[DEBUG] (src/casset.c:file_load:282) Loading: '/.../Corange/assets_core/fonts/console_font_0.dds'
[DEBUG] (src/cui.c:ui_elem_new_type_id:125) Creating UI Element score (ui_button)
[ERROR] (./src/kernel.c:kernels_check_error:156) OpenCL error on clEnqueueWriteBuffer: Out of resources

And, if I compile with VOLUME_RENDERER only (without MARCHING_CUBES) the program compiles, runs, hangs and in the worst case I have to turn off my PC.

Unluckily I know almost nothing about OpenCL programming, and I'm not going to use openCL with Corange anyway. So it's OK for me.

I'm just sad I cannot help further to port this demo :sob: !

Me too :D

Someone who understands will come and fix it =)

It is worth making a contribution only in those things that you know and that will be useful to you and everyone. Personally, I offered solutions to those problems that I faced myself and they interfered with me and I was sure they interfere with others. I know at least 10 places where fixes and improvements are needed, but I pray for them. They do not bother me, I do not know how to correct them and others do not talk about them. The one who understands and fixes will come if he is not too lazy =)

relax :D Understand the code because you like it, not because you owe someone. :tea:
