Good evening. After making a git pull and rebuilding KOS, my code, that previously worked, throws the following errors on lxdream : Descobertos 16 ficheiros para carregar rewinddir: call ignored A carregar o .png inside add_texture: string duplicada overlay WIDTH : 512, HEIGHT : 64 H: 64 W: 512 text...

So Dreso741, when will we be able to try out your lib ? Best Regards. I hope to go into an open testing phase of the graphics module by christmas, but I could always use help with testing, documentation, etc. If you're interested in that PM me and I'll get back to you. Why not create a repo and let...

Adding support for simple 2d Overlays. (useful to put graphics such as logos, etc on the screen).

So Dreso741, when will we be able to try out your lib ?

Best Regards.

Problems while compiling examples : make[4]: Leaving directory `/home/jaerder/development/Tools/dreamcast/kallistios/examples/dreamcast/kgl/demos/mipmap' make -C multitexture make[4]: Entering directory `/home/jaerder/development/Tools/dreamcast/kallistios/examples/dreamcast/kgl/demos/multitexture' ...

Good Afternoon. I've checked out the latest version of the API, but now I get the following error : /home/jaerder/development/Tools/dreamcast/kallistios/utils/bin2o/bin2o romdisk.img romdisk romdisk.o kos-cc -o bin/main.elf bin/asset_loader.o bin/data_estructures.o bin/dc_render.o bin/fnt_parser.o b...

Good evening. When glEnable(GL_KOS_NEARZ_CLIPPING); on lxdream it simply shows a blank screen with a matching glclear() color, until the emulator crashes with --- Aborting with signal 11 --- Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sy...

Well, this is my code running on real HW, but it has some bugs that did not appear on lxdream.



I wonder on how I'm going to debug something running on the real HW..........hummmmmm gotta see if I can get DDD and GDB running on DC hw....

MisterDave, how did you embed the video on your post ?

Good afternoon. Hi PH3N0M, the fix did indeed work, but the bitmapped font and the render to texture on my code stopped working. (To be fair, I've pulled the latest version and did the editing you suggested , instead of testing first and then making the edit). How do I revert my copy of libgl ? Usin...

After some tests, the issue seems to go away if I comment the following code : glGenTextures(1, txr); glBindTexture(GL_TEXTURE_2D, *txr); glKosTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, iw, ih, 0, PVR_TXRFMT_TWIDDLED, PVR_TXRFMT_ARGB4444, txaddr); Therefore it appears that the gl related textures are cha...

Good Morning. I've been writing a simple progress bar to show load progress. Although I'm only drawing a quad and setting is color with glColor3f(), the quad's color changes when a texture is loaded, even with glDisable(GL_TEXTURE_2D). And I've been unable to find the cause of this artifact so far. ...

Looks very good MisterDave! What algorithm do you use create the blur ?

Best Regards!

Thank you BlueCrab! It worked after this edit was suggested : void pvr_to_grayscale(pvr_ptr_t texture_ptr, long unsigned int w, long unsigned int h) { uint16** txt_ptr = texture_ptr; uint16 bytemask_r = 0xF800 ; uint16 bytemask_g = 0x7E0 ; uint16 bytemask_b = 0x1F ; uint16 r = 0 ; uint16 g = 0 ; uin...

Good Evening. I've been attempting to directly modify the texture returned glutCopyBufferToTexture(); function, but I've been unable to access and modify its contents via the pvr_ptr_t. In this example I'm attempting to convert a a RGB 565 texture to gray scale (without changing the texture format o...

Good afternoon. I've been having a odd issue while using the render the texture feature. I've copied the code from the examples (the radial blur example) that came with libgl and I'm rendering the texture into a quad (using ortho projection). I'm initializing the texture just like the example and, i...

Starting to experiment with the render to texture feature.

Although que quad only appears mid scene (due to some bug I'm still hunting).

PH3N0N, glClearColor(1.0f, 1.0f, 1.0f, 1.0f); , appears to have no effect. I should have mentioned that I did not plan to be fully backwards compatible with old KGL API. The old KGL was not exactly doing things by the standard, so in some areas I attempted to be a bit closer to the standard. If you...

My issue is now fixed. This the the following code to bind a png texture as a OGL texture : (Based on the new examples provided, although I dunno where on earth the .pvr file format came from, I'm only assuming, from the examples, that it is raw texture data plus a header) #include <kos.h> #include ...
