smh not using Linux

-v doesn't work due to compiling issues that I was too lazy to fix; rest should work fine.

Edit: does Windows really think it's a virus <.<

Thanks! I finally got this homebrew to compile.

One more thing, how was an obj converted for use in Citro3D homebrew. Like this one in the loop_subdivision example:

Code:

static const vertex vertex_list[] =
{
	/*0*/ FACE(0.500000, 0.000000, -0.500000, 1.000000, 0.000000, 7),

I can look at the obj file made by blender in a text editor, but I don't know which coordinate goes where.

EDIT: I also don't know what the "index_list" array is.

For anyone else who has used the GPU for rendering textured polygons, how much faster is rendering when textures are stored in VRAM vs FCRAM? Can't check it myself right now as I'm not at home to try.

Hello! I'm having trouble compiling my program, it says

Code:

make[1]: *** No rule to make target `citra.png.o', needed by `/c/Users/XXX/Documents/3ds/3DSPROJECT/output/3DSPROJECT.elf'.  Stop.
make: *** [all] Error 2

The error happens when I want to compile and have a "data" folder with a file named "citra.png". It is the first error to show up, and doesn't even compile the main.cpp file.
EDIT: I'm using this template

If you have cfw, yes.

If you don't have a cfw, then no.

Can I call the GX_DMA function a number of times in a row without having to call the waitforDMA function each time? Are such GX functions set up in a queue form that is actively processed?

Also, I recall having a problem with the waitfor<x> functions, specifically with DMA, where if there wasn't something already being processed, and I called that function, it would lock up my program.

https://www.3dbrew.org/wiki/GSP_Shared_Memory#Command_Header
https://github.com/smealum/ctrulib/blob/master/libctru/source/gpu/gx.c and
https://github.com/smealum/ctrulib/blob/master/libctru/source/services/gspgpu.c#L193

There seem to be 15 slots for GX transfer commands(I didn't know that before I checked the source code), but I didn't test it, so maybe I'm wrong.

DiscostewSM said:

Yes, I know this. If you really have to check when a request has been finished, you can register a callback function(https://github.com/smealum/ctrulib/blob/master/libctru/include/3ds/services/gspgpu.h#L73)

Thanks @catlover007. I'll still be cautious about utilizing them, but I should have enough info to get working with them.

That didn't work... However, I get new errors in citra: http://prntscr.com/ctggh5

--------------------- MERGED ---------------------------

Nvm, got it to work by swapping my charvector with an empty vector.

catlover007 · Oct 13, 2016

I would recommend you to change the vector type from char* to const char*. You're adding constant strings to the buffers, but the pointers look like there are in a modifiable memory region. This may lead to very hard to find bugs.

EDIT: Why aren't you using std::string, it's much more safe.

Thank you so much, I'll do that right now

Is there a good dsp audio example program? I heard csnd is deprecated.

Quantumcat · Oct 16, 2016

I posted about this before and got no replies so I'll probably just get ignored again but I thought I'd try just one last time before giving up completely. Could anyone possibly zip their libctru, libsftd, and libsf2d folders from devkitpro and share it? Assuming you're able to compile stuff. Thanks in advance if anyone would do this.

https://gbatemp.net/threads/ndsp-minimal-example.405907/ -> https://github.com/CurryGuy/ndsp-example/blob/master/source/main.cpp
(in that example, use that fix:
"The reinterpret_cast in not needed at all (at least with latest ctrulib), this fixes the issue:
waveBuf.data_vaddr = (const void*)data;" )
