Questions tagged [irrlicht]

Irrlicht is a free open-source cross-platform real-time 3D engine written in C++. The engine is free for open source and commercial use under the zlib/libpng license.

Irrlicht, like others 3D engines (Ogre, Unity, CrystalSpace, …), enables you to create 3D games and programs without having to deal with low level details.

In a few lines of code, you can load a complex mesh created in a 3D modeling software like Blender, apply a texture to it, add some lighting, fog and other visual effects, render it and even animate it.

For a complete description of the features of the engine, checkout the list of features.

Is there any way to parse an APNG with an unmodified libpng?

I'd like to parse APNGs without modifying libpng. This is important because libpng may get security patches and if I modify libpng I need to maintain my version of it. Is there any way to parse APNGs without a modified libpng?
