SoTextureCoordinateEnvironment.3coin2

NAME

SoTextureCoordinateEnvironment -

The SoTextureCoordinateEnvironment class generates texture coordinates by projecting onto a surrounding texture.

The texture specifying the enviroment will be mapped around the scenegraph below this node using a sphere. The texture will be mapped onto the scenegraph taking camera position into account. This will lead to an object reflecting its enviroment.

SYNOPSIS

#include <Inventor/nodes/SoTextureCoordinateEnvironment.h>

Inherits SoTextureCoordinateFunction.

Detailed Description

The SoTextureCoordinateEnvironment class generates texture coordinates by projecting onto a surrounding texture.

The texture specifying the enviroment will be mapped around the scenegraph below this node using a sphere. The texture will be mapped onto the scenegraph taking camera position into account. This will lead to an object reflecting its enviroment.

Here is a scenegraph example showing how enviroment mapping can be applied to an object:

Inventor V2.1 ascii

Separator {

Texture2 { filename 'ocean.jpg' # the enviroment, in this case ocean } TextureCoordinateEnvironment {}

Cube {} # the enviromentally mapped object }

FILE FORMAT/DEFAULTS:

     TextureCoordinateEnvironment {
     }

Member Function Documentation

void SoTextureCoordinateEnvironment::initClass (void) [static]Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoTextureCoordinateFunction.

void SoTextureCoordinateEnvironment::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

References SoAction::getState().

Referenced by callback(), GLRender(), and pick().

void SoTextureCoordinateEnvironment::GLRender (SoGLRenderAction * action) [virtual]Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoNode.

References doAction(), SoFieldContainer::get(), and SoAction::getState().

void SoTextureCoordinateEnvironment::pick (SoPickAction * action) [virtual]Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

References doAction().

void SoTextureCoordinateEnvironment::callback (SoCallbackAction * action) [virtual]Action method for SoCallbackAction.

Simply updates the state according to how the node behaves for the render action, so the application programmer can use the SoCallbackAction for extracting information about the scene graph.

Reimplemented from SoNode.

References doAction().
