Materials & Textures |
Materials | · Powerful material declaration language · Multiple material · Material LOD · Multi-texture and multi-pass blending · Projective texturing · Textures can be provided and updated in real-time by plugins | · Provide common built in materials based on fixed function pipeline or programmable pipeline · add new materials to Irrlicht at runtime, without the need of modifying/recompiling the engine | |
Textures and Mapping | 自動產生MipMap； 自動調整紋理大小以滿足硬件需求。 支持可程序控制的紋理坐標生成和轉換。 | · Bump mapping · Parallax mapping · Light maps · Sphere mapping | DOT3 Bump mapping 沒有提供多層紋理和混合模式 |
Shaders | · Supports vertex and fragment programs, both written in assembler, and in Cg, DirectX9 HLSL, or GLSL · Support many commonly bound constant parameters like worldview matrices, light state information, object space eye position etc | · Pixel and Vertex Shaders 1.1 to 3.0 · ARB Fragment and Vertex Programs · HLSL · GLSL | · Hardware Vertex Shaders · HLSL |
Scene Management |
General | · Highly customizable, flexible scene management, not tied to any single scene type. · Hierarchical scene graph; nodes allow objects to be attached to each other and follow each others movements, articulated structures etc · Scene querying | · Using a hierarchical scene graph, can mix indoor and outdoor scene seamless together · Extensible hierarchical scene management | |
BSP Support | BSP 場景的天空穹、粒子特效、高級材質屬性，乃至 BSP 的空間分割規則都會被正確識別、自動實現 | · 對 BSP 的特性支持比較貧乏 | 對 BSP 的讀取存在 BUG |
