This is a demo of IrrPhysx with hardware fluids.

NOTE: PhysX hardware acceleration is required.

Credit goes to Chris Mash (JP) from the Irrlicht forums for the original demo and for IrrPhysx 0.2.

Source code included. Requires IrrPhysx 0.3 library source code from the Misc section and the nVidia PhysX SDK v2.8.1 in order to recompile.

IrrPhysx: Physics library for the Irrlicht 3D engine using nVidia PhysX.

This release of IrrPhysx - v0.3 - has added support for Fluids, both in hardware (given a compliant GPU) and software (cpu).

Note: v0.3 was developed on an nVidia GPU with hardware PhysX support. Although software (cpu) fluids are possible with v0.3 the GameExample expects hardware PhysX support.

Credit goes to Chris Mash (JP) from the Irrlicht forums for creating IrrPhysx 0.2 from which this is based.

Hardware Ray Trace Demo (DirectX 10)

arising from the use of this software.

Description
===========
Email : sio2 'at' users.sourceforge.net
Website : http://sio2.g0dsoft.com

This is a demo of hardware ray tracing using the IrrSpintz 3D Engine. It is a modified version of the original nVidia demo. This version makes use of the enhanced capabilities of Shader Model 4.0 under DX10. In addition to the hard-edged shadows of previous DX9 versions, this version also has support for softer shadows.

The scene is rendered by drawing a viewport-sized quad (two triangles) and "tracing" a ray from the viewpoint through each pixel in the viewport. The Pixel Shader calculates the intersection of each ray with primitives in the scene, determines the "closest hit" and then calculates the colour of the given pixel. Reflections are handled by tracing another ray from the intersection point into the scene. The hard-edged shadows of previous versions are calculated by tracing another ray from the intersection point to the light to determine if any other object is blocking the light source. Softer shadows are calculated using a linear approximation of the amount of light that a given point could possibly receive from the scene (a very simple form of radiosity).

Shadows can be switched on and off at runtime and switched between hard-edged and software shadows. This is achieved by sending "bool" values to the pixel shader enabling different execution paths withou the need for a separate shader for all of the possible combinations of shading.

Usage
=====
Move mouse to alter viewpoint.
WASD keys to move camera.
Alt-F4 or Escape key to exit.

F1 - Toggle shadows on/off.
F2 - Toggle between hard-edged and softer shadows.

Requirements
============
OS:
Windows Vista.

Drivers:
Latest DirectX 10.0 drivers (August 2007 or later) [www.microsoft.com/directx].
Latest DirectX 10.0 drivers for your graphics hardware [from your HW vendor].

Graphics hardware with support for:
DirectX 10.0

Supported cards:
DirectX 10.0 (such as nVidia 8 series)

Notes
=====
1. This demo may require the Visual Studio 2005 Redistributable Files installed on your machine. These can be obtained from http://www.sio2.g0dsoft.com in the "Misc" section of "Downloads" or from the Microsoft web site.
2. In previous versions (DX9) Shader Model 3.0 used a "brute force" approach requiring a massive 4083 instruction slots. This Shader Model 4.0 version (DX10) is considerably more efficient in terms of instructions.
3. This demo should run on all DX10.0 hardware.
4. Note the requirements: Windows Vista, a DX10.0 level graphics card and you must have at least the "August 2007" DirectX drivers.

Hardware Ray Trace Demo (nVidia 8800)

arising from the use of this software.

Description
===========
Email : sio2 'at' users.sourceforge.net
Website : http://sio2.g0dsoft.com

This is a demo of hardware ray tracing using the IrrSpintz 3D Engine. It is a modified version of the original nVidia demo.

The scene is rendered by drawing a viewport-sized quad (two triangles) and "tracing" a ray from the viewpoint through each pixel in the quad. The Pixel Shader calculates the intersection of each ray with primitives in the scene, determines the "closest hit" and then calculates the colour of the given pixel. Reflections are handled by tracing another ray from the intersection point into the scene.

The original demo hard-coded the scene objects into the shader; this demo uses Irrlicht scene nodes for the scene objects (spheres and light) and Irrlicht SceneNodeAnimators for animating the scene nodes. Shader constants are gathered for each scene node every frame and uploaded to the pixel shader for calculation of the scene.

NOTE: This updated demo is designed for the nVidia 8800 graphics card or above. The Pixel Shader used by this demo requires hardware with at least 4083 instruction slots.

Usage
=====
Move mouse to alter viewpoint.
WASD keys to move camera.
Alt-F4 or Escape key to exit.

Requirements
============
Drivers:
Latest DirectX 9.0b drivers [www.microsoft.com/directx],
Latest DirectX9 drivers for your graphics hardware [from your HW vendor].

Graphics hardware with support for:
Vertex Shader 3.0 or better
Pixel Shader 3.0, or better.

Supported cards:
nVidia 8 series (8800)

Notes
=====
1. This demo may require the Visual Studio 2005 Redistributable Files installed on your machine. These can be obtained from http://www.sio2.g0dsoft.com in the "Misc" section in "Downloads" or from the Microsoft web site.
2. The pixel shader uses a "brute force" approach, hence the massive 4083 instruction slot. A Shader Model 4 (DX10) version would be considerably more efficient and is planned as a future update.
3. Although this demo will theoretically run on hardware that supports SM3.0 and has 4096 instruction slots (such as nVidia 7800GTX), performance will be extremely poor on any hardware prior to nVidia "8" series graphics cards (such as nVidia 8800).

Motion Blur Demo for the IrrSpintz 3D Engine
============================================

See license.txt for license details.

Email : sio2 'at' users.sourceforge.net
Website : http://sio2.g0dsoft.com

This is a demo of motion blur using the IrrSpintz 3D Engine (Subversion revision 23). The scene is a Quake3 level map in which crates can be "thrown" using the left mouse button. Physics is implemented via the Newton Physics library. Movement of the viewing camera and other objects in the scene is subject to a "motion blur" effect.

Warning - may cause motion sickness!

The demo uses the following features:
1. FP16 floating-point texture support (RGBA16F)
2. Render to FP16 texture.
3. NPOT (non-power-of-two) render-target support.
4. MRT (Mulitple Render Target). If the graphics card supports MRT then two of the passes are folded into one via MRT.
5. Physics.
6. Quake3 map lighting enhanced via a vertex/pixel shader.

Usage
=====
WASD keys or arrow (cursor) keys to move camera.
Move mouse to orientate camera.
Alt-F4 or Escape key to exit.
Keys 0-9 alter blur amount (5=default)
M key toggles MRT on and off (if available).

Requirements
============
Drivers:
Latest DirectX 9.0b drivers [www.microsoft.com/directx],
Latest DirectX9 drivers for your graphics hardware [from your HW vendor].

Graphics hardware with:
Vertex Shader 2.0 support, or better
Pixel Shader 2.0 support, or better.
Support for render-to-texture.
FP16 floating-point texture support (as rendertarget).

Notes
=====
1. This demo may require the Visual Studio 2005 Redistributable Files installed on your machine. These can be obtained from http://www.sio2.g0dsoft.com in the "Misc" section in "Downloads".
2. Quake3 levels can be dark. This demo uses a pixel shader to make the lighting stand out a little better.
3. The demo will use MRT if it is available. Using MRT allows two of the motion blur passes to be folded into a single pass with the two outputs going to separate render-targets.

Overview
========
This is a demo of implementing the MultiAnimation sample from the DirectX9 SDK in the Irrlicht 3D Engine. The sample demonstrates mesh animation with multiple animation sets using high-level shader language (HLSL) skinning and the D3DX animation controller. The animation controller blends animation sets together to ensure a smooth transition when moving from one animation to another.

Usage
=====
The TAB key toggles the Irrlicht GUI on/off.

When the GUI is hidden the camera can be oriented via the mouse and moved with the WASD keys or cursor keys.

When the GUI is visible, information is printed to the screen and the following buttons are enabled:
Add Instance - Add an animated character to the scene.
Next View - Attach the fixed camera to the next character in the scene.
Previous View - Attach the fixed camera to the previous character in the scene.
Reset View - Switch from the fixed camera back to the movable camera.

Alt-F4 or Escape key to exit.

Requirements
============

Latest DirectX 9.0b drivers [www.microsoft.com/directx],
Latest DirectX9 drivers for your graphics hardware [from your HW vendor].

Recommended: Graphics card should support Vertex Shader 2.0 and Pixel Shader 2.0.

Some Vertex Shader 1.1 cards may be supported based on their capabilities.

Notes
=====
1. This demo is Direct3D9 only.

2. This demo may require the Visual Studio 2005 Redistributable Files installed on your machine. These can be obtained from http://www.sio2.g0dsoft.com in the "Misc" section in "Downloads".

3. This Irrlicht build is based on Irrlicht Subversion revision 444.

Hardware Skinned Mesh Demo for the Irrlicht 3D Engine
=====================================================

sio2 'at' users.sourceforge.net

This is a proof-of-concept demo of hardware mesh-skinning using the Irrlicht 3D Engine. Mesh skinning allows an animated mesh to be controlled by an underlying skeleton (hierarchy of bones) - as the skeleton is animated it moves the "skin" mesh. Irrlicht already supports animated meshes, but this demo uses an Irrlicht custom-scenenode and handles the animation in hardware, hence giving a boost in performance. An unmodified Irrlicht dll is used (the source code from which the dll was built is unaltered) - this demo uses functionality exposed by the Irrlicht API.

This demo supports four different skinning methods (five are available - see notes). Some may not be available, based on your hardware capabilities. In general, the "HLSL skinning" method should be fastest. The current FPS (frames-per-second) shows how efficient the current method is (this will be slightly slower with the GUI active - close the GUI to see full performance).

Usage
=====
TAB - toggle GUI (open/close Irrlicht GUI controls).
Move mouse to alter viewpoint (when GUI is closed).
WASD keys to move camera (when GUI is closed).
Alt-F4 or Escape key to exit.

Notes:
When the GUI is open the mouse is used to control the cursor and the drop-down box can then be used to select a different mesh skinning method.
When the GUI is closed the mouse is used to alter the viewpoint of the camera.

Requirements
============

Essential:
Latest DirectX 9.0b drivers [www.microsoft.com/directx],
Latest DirectX9 drivers for your graphics hardware [from your HW vendor].

Notes
=====
1. This demo is Direct3D9 only.

2. One of the five different skinning methods, "Fixed function indexed skinning", does not currently work. This is because Irrlicht creates a Direct3D9 device with HARDWARE_VERTEX_PROCESSING and fixed-function-indexed-skinning in this demo requires MIXED_VERTEX_PROCESSING. This demo is based on an unaltered Irrlich dll so this has not yet been corrected.

3. This demo may require the Visual Studio 2005 Redistributable Files installed on your machine. These can be obtained from http://www.sio2.g0dsoft.com in the "Misc" section in "Downloads".

4. This Irrlicht build is based on Irrlicht Subversion revision 444.

This is a demo of hardware ray tracing using the Irrlicht 3D Engine. It is a modified version of the original nVidia demo.

The scene is rendered by drawing a viewport-sized quad (two triangles) and "tracing" a ray from the viewpoint through each pixel in the quad. The Pixel Shader calculates the intersection of each ray with primitives in the scene, determines the "closest hit" and then calculates the colour of the given pixel. Reflections are handled by tracing another ray from the intersection point into the scene.

The original demo hard-coded the scene objects into the shader; this demo uses Irrlicht scene nodes for the scene objects (spheres and light) and Irrlicht SceneNodeAnimators for animating the scene nodes. Shader constants are gathered for each scene node every frame and uploaded to the pixel shader for calculation of the scene.

NOTE: This updated demo is for graphics cards with high-performance Pixel Shader hardware - see Requirements below. Pixel Shader requires hardware with at least 1191 instruction slots.

This is a simple demo of using the Newton Physics Engine in the Irrlicht 3D Engine. A level map, in Quake3 format, is loaded into Irrlicht (for Irrlicht to render) and the mesh defining this level is used to build a Newton "collision map" for its physics calculations. The user can move the viewing camera around the level and can press the LMB (left-mouse button) to create a new crate (box) and "throw" it into the scene. Crates interact with the level map and other existing crates based on physics calculations by the Newton physics library. A new crate is created each time the LMB is pressed; the maximum crates that can be created is limited by system memory, graphics card and cpu.
