Irrlicht Engine

Hallo

I am trying to recompile Irrlicht 1.84 on either Visual Studio 2015 or 2017. I do not have access to old DirectX SDK (Feb or June 2010). Which SDK should be used to compile this version of Irrlicht within these development environments?

Regards

CuteAlien All I have done is to use CDynamicMeshBuffer instead of SMeshBuffer in the STL and OBJ loaders and adding checking for > 65335 indices. I have tested on a number of models (from Thingiverse). I will send some links to these test models and somebody can then verify the changes. I will look ...

I have changed the STL loader to use Dynamic Buffers and my test model is now loading correctly. I have never submitted any changes re irrlicht - how do I go ahead to add the changes to some kind of version control? The issue was simply related to the fact that the number of vertices was a lot more ...

I will see if I can track the problem down. I need these loaders to work as my application as is CAD system, which uses irrlicht as a 'viewer, but we need to load external models'. I think it is not actually related to the large index buffers, but something else in the files. Is there an example loa...

I converted the file (STL) using an online converter (to .OBJ) and I still had issues. When you look in the .OBJ file the indices has this format :- f 3027//685 3029//1177 3043//685 (as an example) which looks like an index into vertex normals as the 2nd number?? Other .OBJ files do not have the add...

Hello There seems to be an issue with large STL files (more than 65535 vertex indices). I am using 1.8.1. Is this a known issue - has it been resolved. Here is a sample model http://www.thingiverse.com/thing:293268 that does not load correctly. Triangles all over the place. Looks like STL loader onl...

It appears to write the location of the image used as the texture. I have updated the file above, with a new version, with a mesh containing a texture image in it. Maybe this will give you some clues. It appears as if the path might be relative, rather than absolute.

Thanks

Well, well, well... Some success! Enabling the default scene to be exported, certainly made a huge difference. I was not aware of this feature - the model is now loading in Sketch-up. I am still not seeing any textures - i am using :-                         ((IColladaMeshWriter*) writer)->setWriteD...

Any timescales on 1.7.3?

Thanks

For reference, here is the code I use to generate the export files :-                 IWriteFile *out = Device->ifs->createAndWriteFile(Filename);                 if (out)                         {                         IMeshWriter *writer = 0;          DCELMESHPTR Mesh;          PATIT ipos,end = ...

Some progress :- I recompiled the system, using the latest SVN trunk and now the Collada validator test and validates the file correctly. The bad news is however that neither Sketch-up nor Blender loads the file. Neither system generates any useful information as to what the issue(s) might be. For r...

Hello Been trying to create collada (.DAE) files using irrlicht 1.7.2 and I am having some major issues. I tried to create a simple file with a single face in it and then trying to load that in Sketch-up. The face simply has 2 triangles and a material. Sketch-up does not load the file. I then ran th...

Hello

I am upgrading from Irrlicht 1.5 to the 'latest' stable version of the library. Looking at http://irrlicht.sourceforge.net/downloads/ the latest version appears to be 1.7.2, which was uploaded in November 2010! Are there any later stable release available, other than SVN builds?

Thanks

Anton

Are you not allocating a huge amount of memory and then not freeing it? I have had problem when exiting (e.g. it takes a while), when I did not de-allocate memory properly.

Travis I am doing a Hidden Line Removal routine as per the Weiler-Atherton algorithm. This requires 3D polygons to be converted to 2D to enable a polygon clipping routine to then determine visible surfaces. Once the visible lines have been identified, I need to convert it back to 3D (this is an opti...
