Happy new year!

Thanks again.

Strange no idea why image won't show up for you.

You seem to use an invalid SSL certificate on your server: https://imgur.com/a/zREL4A8

Yes, the artifacts look weird. But the UVs are good i think, at least i don't see them in my app: https://imgur.com/a/ZTWHUlR

Hey, thanks for looking into it. Can't see your image, my browser shows a "broken image" icon. I've applied your changes and this is what it looks like with a square texture: https://imgur.com/a/rptS79q Note that i don't use Irrlicht but only the mesh geometry code in a vanilla OpenGL app....

The CGeometryCreator creates cone meshes without texture coordinates despite the comment for CGeometryCreator::createConeMesh says so:

A cone with proper normals and texture coords.

When compiling Irrlicht with GCC in release mode ( NDEBUG=1 ), there are the following switches to GCC: -fstrict-aliasing -fexpensive-optimizations -O3 You can reduce this to -O3 since the other two are already included by -O2 , which in turn is included by -O3 . See https://gcc.gnu.org/onlinedocs/g...

There are 2 spelling errors of "First" in the CNullDriver class (spelled "Frist"):   xx@xxx:~/development/libs/irrlicht/source$ grep -rin frist * Irrlicht/CNullDriver.h:288:     //! this: Frist, draw all geometry. Then use this method, to draw the shadow Irrlicht/CNullDriver.cpp:...

Hi, i think i have discovered a subtle bug in the CPLYMeshFileLoader.   CDynamicMeshBuffer *mb = new CDynamicMeshBuffer(video::EVT_STANDARD, vertCount > 65565 ? video::EIT_32BIT : video::EIT_16BIT);   Shouldn't it check for vertex count > 65536 instead of 65565? Edit: CNullDriver checks for   if ((i...

Thanks, i think i solved it.   unsigned char get_bit(unsigned char *data, const unsigned bitoffset) {     unsigned char c = (unsigned char) (data[bitoffset >> 3]); // X>>3 is X/8     unsigned int bitmask = 1 << (bitoffset & 7);  // X&7 is X%8       return ((c & bitmask) != 0) ? 1 : 0; } ...

Hi, i try to get pixel data out of GIF89a images. Parsing the file works ok, but now i struggle with the LZW encoded image data. I have a byte stream of image data, out of which i need to extract n bits at a time. n can between 2 and 12 inclusive, that means that a code (sequence of bits) can spread...

The app works for me. Your system is broken somehow, for the dynamic loader to crash. Sorry, i forgot to tell that i compile with -lGL compiler switch. Without the OpenGL lib, the app works ok indeed. I've updated the original post. EDIT: Problem is solved: I had to add -pthread to the linker flags...

Hi, i want to convert an std::vector<unsigned char> to std::string. Unfortunately, the application crashes. Can you help me? Edit: The app only crashes when using the -lGL compiler switch. Without it, the app works ok. Edit2: Problem solved, see last post of mine. Example code:   #include <vector> #...

Sorry for bumping, but i just made an example which uses the suggested method to send core::matrix4 Matrix = driver->getTransform(ETS_TEXTURE_0); as a uniform variable. As you can see in the screenshot, only scaling works this way. (Bottom left cube is the shader one, bottom right is textured with t...

@randomMesh: My suspicion (without coding yet) would be that you try to set translation and scaling in the same matrix and one overwrites the other. No, i set scale for one buffer and translate for another buffer. These values are altered in my update method in case it makes a difference.   ... thi...

As CuteAlien said, you can use IVideoDriver::getTransform and pass this matrix manually.

I tried this but it only works for scaling. Translation is ignored.
