iXors3d is based on OpenGL ES 1.1. Implementation of OpenGL ES 2.0 is planned. Rendering: multiple viewports rendering vertex lighting directional point spot fog different FX-flags for entities different blending types alpha testing, alpha sorting order of rendering for different entities frustum culling instancing emulation with automatic generation of texture atlases Meshes: .b3d .md2 .3ds, .ms3d, etc (in development) primitives with automatic uv-mapping (quad, box, sphere, cylinder, cone) skeletal (b3d) and per-vertex (md2) animation children management bones management access to vertex and index buffers Textures: .bmp, .jpg, .png, .tif, .gif, .xbm different use flags (color, alpha, mask, clamped etc) static and animated textures FFP texture blending (alpha, add, multiply, lightmap etc) moving, scaling, rotating Other: ray casting system (different modes of entity picking) mesh collisions and intersections billboards (sprites) heightmap based terrains basic 2d graphics (lines, quads, ovals, text, images) more functionalities are being developed
