Detailed Description

Data required to render tetrahedral meshes.

Provides and interface for the data structures required for rendering a tetrahedral mesh with OpenGL.

Data structures for tetrahedra indexing and face enumeration based on M. Lage, T. Lewiner, H. Lopes, and L. Velho. CHF: A scalable topological data structure for tetrahedral meshes. In Brazilian Symposium on Computer Graphics and Image Processing (SIBGRAPI'05), pp. 349-356, 2005, doi: 10.1109/SIBGRAPI.2005.18

Member Function Documentation

clone()

virtual TetraMesh * inviwo::TetraMesh::clone ( ) const

pure virtual

Implements inviwo::SpatialEntity.

get()

virtual void inviwo::TetraMesh::get ( std::vector< vec4 > & nodes, std::vector< ivec4 > & nodeIds ) const

pure virtual

Fill the nodes vector with the 3D coordinates of each node along with its scalar value (vec4). The scalar is stored in the w component. The nodeIds vector is filled with the node/vertex IDs for each tetrahedron (ivec4). The faces opposite of each node are implicitly encoded. The coordinates are given in Data space and can be transformed to Model space using the Model matrix or SpatialCoordinateTransformer::getDataToModelMatrix().

Implemented in inviwo::VolumeTetraMesh.

getBoundingBox()

virtual mat4 inviwo::TetraMesh::getBoundingBox ( ) const

pure virtual

Return the bounding box of all nodes of the tetrahedral mesh in world space. The bounding box is represented using a mat4, where all positions are between bbox * (x,y,z,1) where x, y, and z are between 0 and 1.

Implemented in inviwo::VolumeTetraMesh.

getDataRange()

virtual dvec2 inviwo::TetraMesh::getDataRange ( ) const

pure virtual

Return the data range of the scalar values

Returns

scalar value range

Implemented in inviwo::VolumeTetraMesh.
