grrlib's Issues

Various issues with the camera

I've found a few issues with the camera recently. The most likely problem is that I'm not using it properly, if I'm not, please tell me.

Problem 1: When using GRRLIB_Camera3dSettings to change the position of the camera, it seems to pivot towards the origin. One way around this is to change the rotation of the same axis by the same amounts.

Problem 2: When rotating the camera, the closer I get to 90 degrees in any direction, the slower the rotation gets. The camera never rotates a full 360 degrees.

Like I said, I'm probably using the camera wrong, this is how I am updating it every frame:
GRRLIB_Camera3dSettings(position.x, position.y, position.z, 0, 1, 0, rotation.x, rotation.y, rotation.z);

GRRLIB_PrintfTTF and GRRLIB_PrintfTTFW do not display the text in correct alpha value

Hi,

I would like to draw text with some transparency, however the text is always drawn fully opaque, no matter the A value in the RGBA color.
Example:
GRRLIB_PrintfTTF(280, 180, GCFont,LG, fontSize, 0xFF000000); or GRRLIB_PrintfTTF(280, 180, GCFont,LG, fontSize, 0xFF000080); will display the same thing as GRRLIB_PrintfTTF(280, 180, GCFont,LG, fontSize, 0xFF0000FF);

I'm not super knowledgeable in C but looking at the underlying GRRLIB code, it seems to me that the alpha component of the RGBA color is never passed down to the final DrawBitmap function. Instead it takes an argument that I don't really understand for the alpha value:

static void DrawBitmap(FT_Bitmap *bitmap, int offset, int top, const u8 cR, const u8 cG, const u8 cB) {
    FT_Int i, j, p, q;
    FT_Int x_max = offset + bitmap->width;
    FT_Int y_max = top + bitmap->rows;

    for ( i = offset, p = 0; i < x_max; i++, p++ ) {
        for ( j = top, q = 0; j < y_max; j++, q++ ) {
            GX_Begin(GX_POINTS, GX_VTXFMT0, 1);
                GX_Position3f32(i, j, 0);
                GX_Color4u8(cR, cG, cB,
                            bitmap->buffer[ q * bitmap->width + p ]);
            GX_End();
        }
    }
}

Question regarding 3D object rotation

It is possible to do multiple transformations in an object "block" (begin - end).

GRRLIB_ObjectViewBegin();
GRRLIB_ObjectViewRotate(0,0,a*4);
GRRLIB_ObjectViewTrans(0,1.0,0);
GRRLIB_ObjectViewRotate(0,0,a*2);
GRRLIB_ObjectViewTrans(0,0.5,0);
GRRLIB_ObjectViewRotate(0,0,a*2);
GRRLIB_ObjectViewEnd();

GRRLIB_DrawCube(0.4f,0.5,0x0000FFFF);

It seems that rotation is always relative to 0,0,0 position.

How can I make my object rotate relatively to a 0,1,0 ?
I need to rotate object like a planet orbit around the sun, not on itself.

//The following code won't work
GRRLIB_ObjectViewBegin();
GRRLIB_ObjectViewTrans(0,1.0,0);
GRRLIB_ObjectViewTrans(0,0.5,0);
GRRLIB_ObjectViewRotate(0,0,a*2);
GRRLIB_ObjectViewEnd();

GRRLIB_DrawCube(0.4f,0.5,0x0000FFFF);

'cannot find -libgrrlib'

Hello,
I was trying to compile the examples, but when I run the make command, I get the following output:
-----------------------------------------------------------
make[1]: Entering directory '/c/grr/examples/3D_CubedTileDemo'

make[1]: Leaving directory '/c/grr/examples/3D_CubedTileDemo'

I made sure that GRRLIB was installed correctly, and it looks like there aren't any issues with the installation.
Am I missing something?

Any idea as to why a particularly large PNG wouldn't load?

So, I have this large .png spritesheet (1616x1920px) and while it seems to load (I DID receive a pointer from GRRLIB_LoadTextureFromFile(), mind you!), the entire texture is transparent (I guess that the image size is "incorrect" according to the docs?). Is there any workaround for this problem that doesn't require manual png edits? Here is a screenshot of code snipped with load attempt results:

error with command make clean all install

when i am installing GRRLIB i dd all until the command make clean all install and it gives me the error:
C:\grr\GRRLIB>make clean all install
make: *** No rule to make target 'clean'. Stop.
can someone help me?

Build on Linux

Hello,
i'm trying to build grrlib on linux, but i get immediately this error:

pngu.c
pngu.c:1290:1: fatal error: opening dependency file /pngu.d: Permission denied
 }
 ^
compilation terminated.
/opt/devkitpro/devkitPPC/base_rules:17: recipe for target 'pngu.o' failed
make: *** [pngu.o] Error 1

This happens for every makefile. it seems the dependeny file is not generated correctly.

Example wont complile

I have devkitpro and have compiles games on it its just grrlib thats giving me issues

Compilation on Ubuntu WSL

I have been making WII stuff without any graphics. Just looking at the registers in Dolphin was good enogh for me but now I want to make actual games. I have been using Ubuntu WSL to compile my code because it is more reliable than msys2 in my opinion. When I tried to install GRRLIB it gave me manny errors. I worked through a few but now I cannot figure it out. I tried running msys2 and it compiled but it is annoying to have to use msys2 rather than WSL which works with VSCode. I get one of two errors

make[1]: Entering directory '/mnt/c/grr/GRRLIB/GRRLIB'
GRRLIB_gecko.c
powerpc-eabi-gcc.exe: fatal error: cannot execute 'cc1': CreateProcess: No such file or directory
compilation terminated.
make[1]: *** [/mnt/c/devkitPro/devkitPPC/base_rules:24: GRRLIB_gecko.o] Error 1
make[1]: Leaving directory '/mnt/c/grr/GRRLIB/GRRLIB'
make: *** [Makefile:4: all] Error 1

or sometimes i get this

liblto_plugin-0.dll not found

I don't really know why it is an issue that i am on WSL rather than msys2 and the only changes that I have made to the original make file is using absoulte path names rather than makefile varibles that had nothing in them. If I did not do this it would fail because it couldnt find powerpc-eabi-gcc.exe

Is it possible that after compiling GRRLIB with msys2 that i could move it to Ubuntu?

Add .OBJ loader

Just found this branch exists. I've my own .OBJ loader implementation (no materials support, just diffuse).
I think would be amazing to have this function implemented in Vanilla GRRLIB.

Do you have any plan to implement it?

Thanks!!!

Examples don't work properly

I was unable to properly run a few of the examples in the newest version of GRRLIB.
Bitmap_fx
3D_sample3
unlimited2D

I didn't test many more of them, None of these properly display textures or text for me, they end up corrupted or don't display at all, however using GRRLIB 4.3.2 seemed to fix the issue.

Some questions you might start asking that I might know and that I can answer are:

Did you install the required libraries? Well yes, I even tried uninstalling and reinstalling the libraries, but that doesn't count.

Now its my turn to ask y'all a question. Why I'm getting this compile error and is there a solution to this?

mkdir: illegal option -- -

When trying to build GRRLIB, i get the error

Missing documentation / weird behaviour with PNG where `size % 4 != 0`

Hi,

This question may have been ask earlier on GRRLIB forum, but I did not find any reference to this issue.

Problem description

There is weird / maybe undocumented behavior with PNG texture loading.
If texture width or height is not multiple of 4, then PNG data is zeroed.

This is due to the following check in GRRLIB_LoadTexturePNG:

GRRLIB/GRRLIB/GRRLIB/GRRLIB_texEdit.c

Lines 173 to 176 in 3ee20bf

 if (imgProp.imgWidth != width || imgProp.imgHeight != height) { 

 // PNGU has resized the texture 

 memset(my_texture->data, 0, (my_texture->h * my_texture->w) << 2); 

 }

Width and height parameter are changed in libpngu in function PNGU_DecodeTo4x4RGBA8 here:

GRRLIB/GRRLIB/lib/pngu/pngu.c

Lines 601 to 602 in 3ee20bf

 if(padWidth%4) padWidth += (4-padWidth%4); 

 if(padHeight%4) padHeight += (4-padHeight%4);

There are others conditions that may update witdh and height but this one is the most obvious and error prone to me.

Questions

What is the exact purpose of this check ?
Why cannot we load not multiple by 4 PNG data ?
When check is removed, all seems to work fine. Is this related to Wii hardware ?

Do we really need to recompute image size + decode PNG data if content is zeroed after ?
Does this check can be moved to libpngu ?
Looking at the code, most PNG loading tricks are not needed if we drop content.
Function can be simplified (see 2654a89).

This may be silly, but what is the exact purpose of libpngu ?
Is it here to make an abstraction layer between GRRLIB and libpng ?
Does it come from somewhere else ? Most of the code in it look unused / dead.

Should we add some documentation on GRRLIB_LoadTexturePNG on the image size multiple by 4 (instead of not correct) ?

Code to reproduce

I have made a branch on repository fork to store code and resources (see commit: 2b73935).

Bellow are some screenshot of running application.

GX_end is static compile warning

Good day all.

just trying to update my libogc to the latest version but I am getting this warning when compiling my current project;

:/devkitPro/libogc/include/grrlib/GRRLIB_fbGX.h:45:5: warning: 'GX_End' is static but used in inline function 'GRRLIB_GXEngine' which is not static
GX_End();
^~~~~~

I get about 17 or so errors anywhere a GX function ( e.g. GX_Color1u32(color[i]); GX_Position3f32(v[i].x, v[i].y, v[i].z); ) is used in GRRLIB. my own code compiles and runs fine. is there anything I can do about the warnings or just ignore them?

GDB and GRRLIB: undefined reference to DEBUG_Init

/opt/devkitpro/devkitPPC/bin/../lib/gcc/powerpc-eabi/13.2.0/../../../../powerpc-eabi/bin/ld: main.o: in function `main':
/Users/lily/sandbox/gamecube-devkitpro-test/source/main.cpp:16:(.text.startup.main+0x20): undefined reference to `DEBUG_Init'

I'm trying to use libogc's implementation of gdb, but I can't seem to get it to work with the template example for GRRLIB.

I'm fairly certain I've written a minimal example here, though I'm relatively new to C/C++ so I could be way off base.

I'm able to build and run the gdbstub.c example from devkitPro, and connect via gdb, and I can build and run the examples for GRRLIB, but I'm unable get gdb working within GRRLIB.

I've included the make command I'm running and its output, the main.cpp file I'm trying to compile, and the Makefile I'm using to build the project.

I'm able to build other libogc and GRRLIB projects just fine, but I'm unsure of next steps for debugging this issue.

Add Video Support

I don't know if i'm asking too much, i'll just say that it would be nice to have some sort of built-in video player for GRRLIB, since some projects will kinda need it for cutscenes and such (like mine for example).

Just by adding the video player and probably a pause and play option will be more than enough.

problem compilng

Whenever I try to compile I get this
powerpc-eabi-gcc: fatal error: cannot specify '-o' with '-c', '-S' or '-E' with multiple files'

Compiling+installing seems to be problematic on GNU/Linux

After installing all the needed packages using pacman, installing GRRLIB seems to fail.

make[1]: Entering directory '/home/peter/gitrepos/GRRLIB/GRRLIB/GRRLIB'
GRRLIB_3D.c
GRRLIB_3D.c:804:1: fatal error: opening dependency file /GRRLIB_3D.d: Permission denied
  804 | }
      | ^
compilation terminated.
make[1]: *** [/opt/devkitpro/devkitPPC//base_rules:18: GRRLIB_3D.o] Error 1

I'm not really sure why this fails, but running it as root seems to work... although that causes the issue of having this later

/opt/devkitpro/devkitPPC/bin/../lib/gcc/powerpc-eabi/10.2.0/../../../../powerpc-eabi/bin/ld: cannot open map file 3D_CubedTileDemo.elf.map: Permission denied

this does compile fine if I set the needed environment variables and run it as root
I'm probably just being stupid, but I'm not really sure if there is a more appropriate way than just opening an issue on this repo.

Drawing 3D over 2D

I'm trying to draw 3D objects over 2D but it seems like doing any kind of 2D operation (including GRRLIB_FillScreen) before 3D ones makes the 3D not show up at all. I'm trying to use GRRLIB_CompoStart and GRRLIB_CompoEnd and then render that out to a texture (which does work if the 3D drawing code is first.) I guess I was kind of expecting it to draw to something like an FBO instead the main frame buffer. However, I can't really render 3D first with my setup, I need to draw some 2D, then some 3D, then some 2D on top of that. Is there any way I can clear all the 2D stuff blocking the way of the 3D stuff so far when doing CompoStart or do I have to always draw 3D first?

pass environment variables in documentation

I think the build instructions should have a note for Linux users to use sudo -E to pass the DEVKITPRO and DEVKITPPC environment variables to Make. I was smart enough to convert the instructions, but I got stuck here for hours.

Bug while installing GRRLIB on Windows

Hi, i try to install GRRLIB on Windows after compiling it and i have this issue :

cp: target '/opt/devkitpro/portlibs/wii/include' is not a directory
make[1]: *** [Makefile:98: install] Error 1
make[1]: Leaving directory '/home/teoja/Documents/Grrlib/GRRLIB/GRRLIB/GRRLIB'
make: *** [Makefile:15: install] Error 1

Can you help me please ?

	if (imgProp.imgWidth != width \|\| imgProp.imgHeight != height) {
	// PNGU has resized the texture
	memset(my_texture->data, 0, (my_texture->h * my_texture->w) << 2);
	}

	if(padWidth%4) padWidth += (4-padWidth%4);
	if(padHeight%4) padHeight += (4-padHeight%4);
