Castle Game Engine: Support for PLY model format and InlineGeometry node

From Castle Game Engine: link to original post

1. We support now loading models in PLY format, commonly used for 3D scanning and printing.
   • We support all common variants, which means ASCII and binary with any endianness.

   • We support both models with faces (loaded to TIndexedFaceSetNode) and without (loaded to TPointSetNode).

   • As usual, “support” means we support them everywhere in our engine and tools. In particular Castle Model Viewer can load them, Castle Model Converter can convert them (to X3D, IFC, STL and soon to glTF), and in our engine editor you can load them inside TCastleScene.

   • They can also be used with X3D TInlineNode and TInlineGeometryNode nodes.

   • For more information about the format follow our docs.

   • Some testcases: Kaktus from Sketchfab (can be downloaded as PLY source) and our demo-models ply subdirectory.

2. We support X3D InlineGeometry node.

   • It allows to get geometry (polygons, vertexes) from an external 3D model and reuse it with a different appearance (material, textures, shader effects).

   • Our testcase is here.

   • More testcases in X3D archives: here and here.

Have fun with Castle Game Engine and 3D standards!
