Detailed Description

Render engine mode.

The render engine mode class indicates how a node performs its rendering. For example, the node can be using OpenGL calls or Open Inventor calls in order to achieve this task.

By default, a custom node is assumed to use the OpenGL compatibility-profile which means that it is allowed to use all OpenGL features even the ones that were deprecated in recent versions. If a node is only using core-profile OpenGL calls, it should give this information to the renderer using this enum.

However, it is strongly encouraged to avoid calling directly OpenGL methods to perform the rendering of a node and rely on Open Inventor instead. Using only Open Inventor calls is the optimal way as it allows harnessing a wide range of optimizations that are not available when using direct OpenGL calls.

Member Enumeration Documentation

RenderMode

enum SbRenderEngineMode::RenderMode

Defines the list of supported render mode for a custom node.

Enumerator
OIV_UNKNOWN_RENDERING_MODE	Internally used to detect that a node did not set explicitly its RenderEngineMode by calling setRenderEngineMode method (This is the default). If parent class has called setChildrenInherit(true), then this node type will inherit it. Else a warning will be issued and OIV_OPENINVENTOR_RENDERING will be used.
OIV_OPENINVENTOR_RENDERING	The node uses only Open Inventor calls to perform its rendering (optimal way)
OIV_OPENGL_COMPATIBILITY_RENDERING	The node relies on OpenGL fixed-function pipeline & deprecated features (OpenGL compatibility profile)
OIV_OPENGL_CORE_RENDERING	The node uses OpenGL but only shader and modern features (OpenGL 3.3+ core profile)

Constructor & Destructor Documentation

SbRenderEngineMode()

SbRenderEngineMode::SbRenderEngineMode ( )

inline

Default Constructor.

Definition at line 52 of file SbRenderEngineMode.h.

Member Function Documentation

enableWarnings()

static void SbRenderEngineMode::enableWarnings ( bool flag )

static

Enable or disable RenderEngineMode warning messages.

Default is true. Default value can be changed by using OIV_OPENGL_COMPATIBILITY_WARNING environment variable.

getRenderMode()

RenderMode SbRenderEngineMode::getRenderMode ( ) const

inline

Returns the current RenderMode.

Definition at line 89 of file SbRenderEngineMode.h.

isChildrenInherit()

bool SbRenderEngineMode::isChildrenInherit ( ) const

inline

Returns true is derived node should inherit this RenderMode.

Definition at line 103 of file SbRenderEngineMode.h.

isNotDefined()

bool SbRenderEngineMode::isNotDefined ( ) const

inline

Return true if the RenderMode has not be defined explicilty.

Definition at line 109 of file SbRenderEngineMode.h.

postInitWarning()

static void SbRenderEngineMode::postInitWarning ( const char * methodName )

static

Post a warning related to Open Inventor 10 OpenGL support.

SbRenderEngineMode has not been set before SO__NODE_INIT_CLASS macro by a custom node.

setChildrenInherit()

void SbRenderEngineMode::setChildrenInherit ( bool isChildrenInherited )

inline

Indicates if any derived node should inherit this RenderMode.

Default is false

Definition at line 97 of file SbRenderEngineMode.h.

setRenderMode()

void SbRenderEngineMode::setRenderMode ( RenderMode renderMode )

inline

Set the RenderMode.

Default is OIV_UNKNOWN_RENDERING_MODE. If you specify your node type in the initClass() method, this method should be called before calling the SO_NODE_INIT_CLASS macro
