Detailed Description

The SuperShape node implements a SuperShape!

A SuperShape is an implementation of the SuperFormula. The SuperFormula is a formula that can be used to describe geometric shapes found in nature. For information about the parameters defining the SuperShape see 2d-equation on http://local.wasp.uwa.edu.au/~pbourke/surfaces_curves/supershape3d/ This geometryNode implements a 3D-version of the SuperFormula by using two functions. The parameter names for one function is ss1_x and for the other it is ss2. Experiment with values to see what they do.

Examples:

Member Function Documentation

◆ render()

void SuperShape::render ( )

virtual

the render() function is used for the depth-first rendering traversal of the scene-graph.

Reimplemented from H3D::Node.

References coord, H3D::GlobalSettings::getActive(), H3D::GlobalSettings::getOptionNode(), H3D::X3DGeometryNode::getOptionNode(), normal, H3D::GraphicsOptions::preferVertexBufferObject, H3D::Node::render(), and resolution.

◆ startTexGen()

void SuperShape::startTexGen ( )

protected

Start texture coordinate generation.

Texture coordinates will be generated for all texture units used by the currently active texture. Texture coordinates will be generated from the bounding box of the geometry

References H3D::H3DBoundedObject::bound, H3D::BoxBound::center, H3D::X3DTextureNode::getActiveTexture(), H3D_FULL_LOCATION, H3DAbs(), H3D::BoxBound::size, and H3D::MultiTexture::texture.

◆ traverseSG()

void SuperShape::traverseSG ( TraverseInfo & ti )

virtual

Traverse the scenegraph.

A HAPIHapticShape is added for haptic rendering if haptics is enabled.

Parameters

ti	The TraverseInfo object containing information about the traversal.

Reimplemented from H3D::X3DGeometryNode.

References H3D::X3DGeometryNode::traverseSG(), and H3D::X3DGeometryNode::useBackFaceCulling().

◆ coord

H3DUniquePtr< SFCoordinateNode > H3D::SuperShape::coord

protected

Field that contains a Coordinate node with the coordinates generated by SuperShape.

C++ only field.

Referenced by render().

◆ normal

H3DUniquePtr< SFNormalNode > H3D::SuperShape::normal

protected

Field that contains a Normal node with the normals generated by SuperShape.

C++ only field.

Referenced by render().

◆ resolution

H3DUniquePtr< SFInt32 > H3D::SuperShape::resolution

Parameter to define the resolution of the supershape.

A higher value generally give a shape that more closely follows the values generate by the implicit SuperFormula than a lower value.
