Currently, the cube plugin uses mipmapping only when cube is unfolded. When the cube is rotated, mipmaps are not used, which leads to ugly look of textures. The attached patch fixes this. This leads to another kind of artifacts, which are fixable with anisotropic filtering. http://team.pld-linux.org/~wolf/aniso.png The leftmost image is the current state of cube plugin. The center image is with mipm...

I'm currently implementing mipmaps but I have a set of troubles guessing the block height and block depth of them. According to https://envytools.readthedocs.io/en/latest/hw/memory/g80-surface.html#textures-mipmapping-and-arrays the texture unit auto resizes mipmaps' blocks but how do I know how many blocks each one uses? I'...

...is the size of the mipmap level, should be used. Second, the current code does not 64-byte align the pitch of swizzled textures. However, on my NV40 this causes a pgraph error regarding the pitch register (and sometimes a system lockup too), which is fixed by this patch. I'm not sure how small mipmaps could have worked with the previous code. Also the offset code below may need some review. And furthermore, wide_pitch is set for any kind of texture usage, so maybe it should be made unconditional (what's the point of allocating a texture that the GPU can't use in any way?). diff --git a...

Hello, I have been looking at cubic texture mapping for a bit, and I have found that hw mipmap generation doesn't work at all or the textures are all messed up (normal 2d work fine). This is with linear textures. Also of note is that software mipmap generation works fine. I have done sanity checks for the miptree pitches, offsets, etc and everything seems to match up fine for both the

Hi, I've been trying to get the new i915tex DRI module to work with the new DRM memory manager and finally succeeded. Unfortunately it seems to break compiz which errors out complaining that there are no GLXFBConfigs for the default depth. I was able to trace the problem to the following block of code in src/screen.c, starting on line 1897: if (s->fbo) { (*s->getFBConfigAttrib)

I'll check that once the 2D code is otherwise finished and working * Swizzled 1D/2D/3D textures Mipmaps are laid sequentially with no gap in between. Each mipmap is laid "swizzled". To get the swizzled address of a texel, take an x bit, then an y bit, then a z bit and so on. If you exceed a dimension, skip taking their bits. This means in particular that 3D textures are "3D swizzled&qu...

Hi Why is the quality of scaled textures/objects using --indirect-rendering much worse than direct rendering? Also, vsync does not work with indirect-rendering. I am using an Nvidia Geforce go 7300, with 97.55 drivers. Thanks, Matt

Hi guys again. A homebrew developer (homebrew is custom software made for the switch using openGL under nouveau) reported to me that 'glGenerateMipmap' wasn't working on yuzu (Nintendo Switch emulator). I looked into it and I noticed all the triangle data used by nouveau to render the mipmaps was all zeroed out, meaning that probably we don't implement the mechanism you guys use to upload that data. How can I track this in your code and know what you guys use to upload the triangles data into gpu memory ? -------------- next part -------------- An HTML attachment was scrubbed... UR...
