Detailed Description

The SoProfileCoordinate3 class is a node specifying a set of 3D coordinates for profiles.

Use nodes of this type to provide coordinates to profiles.

The third element of the coordinate vectors is used for normalization. A node of this type where all the normalization values are equal to 1.0 is the equivalent of setting up an SoProfileCoordinate2 node.

Note that an SoProfileCoordinate3 node will replace the profile coordinates already present in the state (if any).

FILE FORMAT/DEFAULTS:

     ProfileCoordinate3 {
         point 0 0 1
     }

Member Function Documentation

void SoProfileCoordinate3::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 SoNode.

void SoProfileCoordinate3::doAction (SoAction * action) [virtual]This function performs the typical operation of a node for any action.

Reimplemented from SoNode.

References SoMField::getNum(), SoAction::getState(), SoMFVec3f::getValues(), and point.

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

void SoProfileCoordinate3::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().

void SoProfileCoordinate3::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().

void SoProfileCoordinate3::pick (SoPickAction * action) [virtual]Action method for SoPickAction.

Does common processing for SoPickAction action instances.

Reimplemented from SoNode.

References doAction().

void SoProfileCoordinate3::getPrimitiveCount (SoGetPrimitiveCountAction * action) [virtual]Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoNode.

References doAction().
