Ogre2GpuRays Class Reference

Gpu Rays used to render range data into an image buffer The ogre2 implementation takes a 2 pass process to generate the final range data. 1st Pass: Creates a cubemap of range data. The cubemap is created from six cameras looking in all directions. Depending on the min/max angles specified, not all cameras need to be created. Internally in the 1st pass shaders, we reconstruct 3d viewspace pos from depth buffer data then convert them into ranges, i.e. length(pos.xyz). 2nd Pass: Samples range data from cubemap using predefined rays. The rays are generated based on the specified vertical and horizontal min/max angles and no. of samples. Each ray is a direction vector that is used to sample/lookup the range data stored in the faces of the cubemap. More...

Detailed Description

Gpu Rays used to render range data into an image buffer The ogre2 implementation takes a 2 pass process to generate the final range data. 1st Pass: Creates a cubemap of range data. The cubemap is created from six cameras looking in all directions. Depending on the min/max angles specified, not all cameras need to be created. Internally in the 1st pass shaders, we reconstruct 3d viewspace pos from depth buffer data then convert them into ranges, i.e. length(pos.xyz). 2nd Pass: Samples range data from cubemap using predefined rays. The rays are generated based on the specified vertical and horizontal min/max angles and no. of samples. Each ray is a direction vector that is used to sample/lookup the range data stored in the faces of the cubemap.

Constructor.

~Ogre2GpuRays()

virtual ~Ogre2GpuRays ( )

virtual

Destructor.

Member Function Documentation

ConnectNewGpuRaysFrame()

virtual common::ConnectionPtr ConnectNewGpuRaysFrame ( std::function< void(const float *_frame, unsigned int _width, unsigned int _height, unsigned int _channels, const std::string &_format)>  _subscriber )

overridevirtual

Copy()

virtual void Copy ( float *  _data )

overridevirtual

Copy to the specified memory direction the gpu rays data.

Reimplemented from BaseGpuRays< Ogre2Sensor >.

CreateRenderTexture()

virtual void CreateRenderTexture ( )

virtual

Create dummy render texture. Needed to satisfy inheritance.

Data()

virtual const float* Data ( ) const

overridevirtual

All things needed to get back z buffer for gpu rays data.

Returns

Array of gpu rays data.

Implements GpuRays.

Destroy()

virtual void Destroy ( )

overridevirtual

Destroy any resources associated with this object. Invoking any other functions after destroying an object will result in undefined behavior.

Reimplemented from Ogre2Node.

Init()

virtual void Init ( )

overridevirtual

Reimplemented from Ogre2Node.

PostRender()

virtual void PostRender ( )

overridevirtual

Preforms any necessary final rendering work. Once rendering is complete the camera will alert any listeners of the new frame event. This function should only be called after a call to Render has successfully been executed.

Reimplemented from BaseCamera< Ogre2Sensor >.

PreRender()

virtual void PreRender ( )

overridevirtual

Prepare this object and any of its children for rendering. This should be called for each object in a scene just before rendering, which can be achieved by a single call to Scene::PreRender.

Reimplemented from BaseCamera< Ogre2Sensor >.

RenderTarget()

virtual RenderTargetPtr RenderTarget ( ) const

overridevirtual
