Features
General Features Object-Oriented Design, Plug-in Architecture, Save/Load System, Other:
• Physics, Database, Networking, VR input devices, Stereo display, Force feedback, Pathfinding, Per-pixel shading, Plug-in structure with SDK
• 5DT data glove support
• Support for force feedback input device
• Publish as single executable, installer, webpage, or screen saver.
• No programming commands or script, fully graphical interface!
Scripting
• Quest3D uses a graphical form of scripting. The graph editor allows you control the dataflow and logic of your project by drawing relations. This method is better than traditional scripting in many cases. It provides much more room for experimenting and you never have to worry about syntax. An additional benefit is that this method does not need any compilation and is extremely fast.
• In some cases might rather use traditional scripting. The expression system is a very simple form of scripting. The next version of Quest3D will have Lua scripting build in which is one of the fastest script languages and uses little memory.
Built-in Editors Quest3D's main strength is the editor. The editor allows you to control every detail of your project using very intuitive, task specific interfaces. The interface is completely customizable and has friendly feel to it.
Physics Basic Physics, Collision Detection, Rigid Body, Vehicle Physics:
• Quest3D uses ODE for physics. Create complex physics simulations using the graphical interface.
• Provides collide and slide collision for simple character collision.
• Can use ray intersections, sphere and box intersection tests.

• Dynamic lighting (up to eight lights, types: spot, omni and linear)
• Diffuse and specular lighting
• Import radiosity light maps from applications such as MAX and Maya
• Build-in light map ray tracer
Shadows Shadow Mapping, Projected planar, Shadow Volume:
• Quest3D can either use hardware or software shadow volume creation.

• Quest3D includes a texture tool that allows you to map textures. Cube maps are supported.
• Bump mapping using environmental bump map technique

Shaders Vertex, Pixel:
• Quest3D includes vertex colors support (.x import) and several per-pixel shaders are provides. HLSL is planned for the next version.
Scene Management General, BSP, LOD:
• Quest3D is not optimized for portal rendering or anything. The BSP is used for collisiona and path finding. There is optimized rendering for huge character crowds and massive vegitation.
